    Hydraulic Lifts: A Comprehensive Guide

    Hydraulic lifts are powerful devices used to handle heavy loads in manufacturing warehouses, construction sites, and other industrial environments. Available in a range of designs, these ergonomic lifting solutions enhance the safety and efficiency of various material handling tasks. Below, we provide a general overview of hydraulic lifts, including the following topics:

    What is a Hydraulic Lift?

    Hydraulic lifts use a hydraulic cylinder system to lift, move, and position heavy loads. While their designs vary depending on the intended application, all hydraulic lifts function using the same basic components:

    • A hydraulic cylinder enclosing a piston
    • A reservoir for oil storage
    • A pump for generating fluid energy
    • A motor for generating mechanical power
    • Valves for manipulating fluid flow

    How do Hydraulic Lifts Function?

    During lift operation, a pump pushes an incompressible oil from the oil reservoir to the cylinder. This pushes the piston upward, providing the force necessary to raise the lift. Once the desired height is reached, the pump is switched off and the lift is held securely in position by the oil trapped within the cylinder. To return the lift to its original position, a valve is opened to release oil back into the reservoir, and the piston is lowered by gravitational force.

    Depending on the position, size, and operation of the cylinder, hydraulic lifts can be categorized as holed or hole-less systems. With holed hydraulic systems, the cylinder extends into a hole in the ground at a distance that is equivalent to the lift’s maximum vertical travel height. In contrast, hole-less hydraulic systems use a direct-acting piston to raise the lift, eliminating the need for a hole.

    Hydraulic lifts consist of several interacting systems:

    • Circuits. A hydraulic circuit is designed to control the flow and pressure of the liquid.
      Pump. Hydraulic pumps are responsible for converting mechanical energy to hydraulic energy. The mechanical action of the pump creates a vacuum at the inlet. This forces the liquid to move from the reservoir to the inlet line, then through the outlet to the hydraulic system.
    • Motor. The hydraulic motor is a rotary actuator that converts hydraulic energy into torque and rotation.
    • Cylinder. The cylinder converts hydraulic fluid energy into force and creates pressure in the fluid.
    • Piston. The hydraulic piston, which is housed within the cylinder, moves upward in response to fluid pressure.
    • Fluid. The hydraulic fluid allows power to be transferred throughout the system. While water and mineral oil are the most common hydraulic fluids, other options include:
      • Glycol ether
      • Organophosphate ester
      • Polyalphaolefin
      • Propylene glycol
      • Silicone oil

    Types Of Hydraulic Lifts

    Hydraulic lifts are available in several types, each of which is optimized to meet specific load, safety, and mobility requirements. These include:

    • Table lifts. Available in scissor or column-type designs, table lifts are ideal for lifting heavy loads across relatively short vertical distances.
    • Personnel lifts. Personnel lifts are designed to safely raise personnel above ground level for maintenance, stocking, and other activities. Lightweight and portable, these lifts are suited for applications in which space is limited or weight is a concern.
    • Forklifts. Forklifts are powerful devices that lift and transport heavy loads in warehouses, construction sites, and other industrial settings.
    • Medical lifts. In the medical industry, medical lifts allow patients with limited mobility to be easily and safely moved by caregivers.
    • Automotive lifts. Automotive lifts are designed to elevate vehicles to a comfortable working height for maintenance and repair tasks.
    • Post car lifts. Post car lifts feature sturdy symmetrical columns positioned directly across from one another. This design aligns the vehicle’s center of gravity with the lift, ensuring that the load is evenly distributed across the columns, carriage, and bearings.
    • Platform lifts. Platform lifts feature a supportive platform that is raised and lowered using crisscrossing braces. These lifts are useful for ceiling construction, cable wiring, and other tasks performed at elevated levels.
    • Pallet lifts. Pallet jacks are used to lift and transport pallets and palletized loads in warehouses and trailers.
    • Hand-pumped lifts. Designed for manual operation, hand-pumped lifts utilize a hydraulic hand pump to raise and lower loads.

    Types of Hydraulic Lift Tables

    Hydraulic lift tables safely raise and lower loads in heavy-duty material handling processes. Types of lift tables include:

    • Mobile. Mobile lift tables are portable solutions for raising and accurately positioning heavy loads. Commonly used in warehouses and manufacturing plants, they help prevent strains and injuries related to the handling and inspection of heavy or bulky items.
    • Rotating. Ideal for assembly applications, rotating lifts are equipped with a rotating top that allows easy access from multiple sides.
      Low profile. With their low collapsed height, low profile lift tables allow for ergonomic lifting of heavy loads from the floor. Their design also provides easy access for pallet jacks.
    • Stainless steel. Stainless steel lift tables offer a durable and corrosion-resistant solution for handling loads in corrosive or harsh industrial environments.
    • High capacity. Ideal for large loads and heavy cargo, high-capacity lift tables feature a robust and durable platform with a wide base to maximize stability.
    • Ground entry. Ground entry lift tables provide access to pallet jacks for easy loading and unloading. Loads can also be positioned to various ergonomic working heights for inspection, maintenance, and other tasks.
    • Tilting. Tilting lift tables feature lift heights and tilt angles that can be independently controlled, making them great for applications requiring precise positioning of large loads.
    • Tandem. Tandem lift tables incorporate two standard base frames connected by a single platform. This design provides increased stability and safety when handling long or wide loads.
    • Multi-stage. Multi-stage lift tables are light-capacity units featuring a small platform supported by two stacked pairs of scissor legs. This allows vertical travel to be maximized while maintaining a small, compact design.

  5. Hydraulic vs. Pneumatic Systems

    Leave a Comment

    Pneumatic and hydraulic systems use fluid power to increase pressure and move mechanical parts in machinery. While pneumatic systems use compressible air or pure gas to achieve their function, hydraulic systems use compressible liquid, such as oil. Commonly seen in lifts and other handling equipment, pneumatic and hydraulic systems offer many advantages, making them ideal for a wide range of applications.

    Hydraulic Vs. Pneumatic Lifts

    Lifts refer to equipment used to raise or lower objects, such as people, cargo, heavy machinery, and more. In order to produce the upward pushing force necessary to move objects, lifts utilize a range of actuating mechanisms and components. The two most common actuator types include hydraulic and pneumatic.

    Hydraulic Lifts

    Hydraulic pneumatic systems

    Hydraulic lifts utilize a lifting mechanism that compresses a liquid, such as oil, to increase pressure within the cylinder, generating the linear motion that is needed to raise and lower the platform and object. Capable of producing more than 25x the force of pneumatic lifting systems, hydraulic lifts can tolerate very heavy loads. Hydraulic lifting mechanisms can also hold torque and force at a constant level without continuous fluid flow, unlike their pneumatic counterparts.

    One primary concern of hydraulic lifts is their environmental impact. Since these mechanisms use hydraulic fluid, they can be damaging to the environment in the event of a leak. Additionally, hydraulic lifts tend to take up more space due to having several components and parts, meaning they are best for applications where space isn’t a primary concern.

    Pneumatic Lifts

    The lifting mechanism within a pneumatic lift utilizes a hollow cylinder and piston. Through the use of an external motor or pump, the piston moves within the cylinder to increase air pressure, allowing the cylinder to move and create enough linear force to extend the lift components.

    One primary advantage of pneumatic lifts is their versatility. Since most pneumatic lifts don’t require electricity, they are suited for a variety of applications, including those exposed to extreme temperatures and other environmental conditions. Pneumatic systems are also very accurate, capable of generating extreme force, and less expensive than hydraulic systems.

    However, pneumatic lifts must maintain operating pressure during use, making them less efficient and more costly to run than other lift types. Also, pneumatic actuators are normally sized for specific applications, limiting them to the needs of that application’s specifications and requirements.

    Applications for Hydraulic and Pneumatic Systems

    While both hydraulic and pneumatic systems are powerful lifting tools, they are each suited to their own applications.

    Hydraulic Applications

    Hydraulic lifts are incredibly powerful and offer superior strength and capacity, making them ideal for the following applications:

    • Car Lifts
    • Dump Truck Lift
    • Elevators
    • Excavating arms for diggers
    • Forklifts
    • Turbines
    • Wheelchair Lift
    • Wing Flaps on Aircraft

    Pneumatic Applications

    Pneumatic actuators can be matched precisely to the power needs of each given application. They also don’t pose an environmental hazard because they use air instead of oil. Having the ability to absorb some amounts of shock, they are ideal for automotive and other sensitive applications. Some of the most common applications include:

    • Air brakes used by buses, trucks, and trains
    • Air compressors
    • Compressed-air engines and vehicles
    • Conveyor systems in pharmaceutical and food industries
    • Explosion-proof work areas
    • Manufacturing and assembly lines
    • Precision drills used by dentists
    • Pressure sensors, switches, and pumps
    • Vacuum cups for sheet lifting

    Leave a Comment

    Lift tables are simple yet versatile tools that help employees lift, lower, or reposition heavy loads of all kinds. In the medical industry, these lifts serve many critical functions. As a stable and quick lifting solution, lift tables enhance safety and efficiency in medical applications from patient care to medical equipment assembly. 

    Lift Tables for Patients

    Lift tables are devices that utilize a valve and hydraulic cylinder to raise or lower objects and/or people. As an easy to use, cost-effective lifting solution, lift tables are highly beneficial for enhancing safety, mobility, and productivity in many instances, especially when used for patient care applications. 

    Medical lift tables are commonly used as patient positioners in settings such as hospitals, rehab facilities, and more. Patients with mobility challenges, such as wheelchair users, require special support in a healthcare environment. Healthcare providers can use lift tables to provide a safe and easy means of positioning these patients since they may have difficulty moving on their own. 

    Common patient positioning applications include:

    • Overbed tables
    • Helping support patient’s arms or legs when extended from an exam table 
    • Transitioning patients from a bed to a wheelchair (commonly known as Hoyer Lifts)

    Speed and stability are critical concerns in hospital environments and other medical settings. Lift tables help to eliminate these concerns by allowing healthcare providers to quickly and safely move or position patients so that they can receive the medical attention they need, especially in surgical or emergency situations. 

    Medical Equipment Assembly Lifts

    Lift tables are also commonly used in manufacturing for medical equipment assembly. Mass production of medical equipment relies on assembly lines to rapidly build products step by step. As each piece of equipment passes through the assembly line, factory workers perform repetitive movements, such as turning, twisting, and lifting, to complete manual assembly tasks. Performing these repetitive tasks hundreds of times per day puts workers at serious risk for injury; therefore, proper ergonomics are critical, especially in medical equipment assembly lines where workers must handle heavy, bulky, or fragile components.

    Lift tables provide the power and stability to move heavy loads without placing repetitive strain on employees. Used in an assembly line, they drastically reduce the effort required to lift and lower raw components, increasing efficiency and reducing the likelihood of mistakes and injuries. At Unidex, we provide lift tables for assembly line manufacturing of respirators, x-ray machines, and other critical care equipment.

    Lift tables also serve as adjustable-height workbenches, which allow employees to quickly raise or lower the surface to a comfortable level. On an assembly line, this is yet another way of ensuring a safe and ergonomic work environment, eliminating the strain of reaching for an improperly positioned work surface. These advantages carry over to pharmaceutical companies as well, who use adjustable-height workbenches to quickly reconfigure testing and assembly areas depending on the needs of their employees.

    Lift Tables from Unidex

    Critical Applications That Require Ergonomic Lifting Solutions

    In the military and defense sectors, the products employed must demonstrate a high level of quality, dependability, and safety. This requirement is true for all materials, machines, and systems, including material handling equipment.  

    Material handling equipment finds applications in many military and defense operations, ranging from the loading and unloading of supplies to the transport of materials from one location to the next. In these often critical and sensitive situations, it’s important the lifting and positioning solutions are designed and manufactured to provide optimal performance without the risk of operator injury.

    The following blog post discusses the importance of integrating ergonomic design into Mil-spec material handling equipment and provides examples of the equipment used in military and defense applications.

    The Importance of Ergonomics in the Military and Defense Industries

    In the workplace, the term “ergonomics” refers to the design and optimization of equipment and a facility’s layout to suit the employees. While it is generally used when referring to offices and warehouses, its principles can be applied to all industries, including military and defense.

    Ultimately, the goal of ergonomic design is to make the workplace safer and more efficient. These benefits then translate to lower risk of operator injury, higher employee productivity, and greater overall morale. Within the military and defense industries, the use of ergonomic material handling systems result in the following:

    Lower Risk of Injury to Life and Limb

    Well-designed lifting and positioning equipment can accommodate large and heavy materials without significant risk to the machine operator. On the other hand, the wrong equipment can increase the risk of employees experiencing back injuries as a result of lifting, handling, or carrying objects.

    Some of the factors that can cause back injury include:

    •   Awkward positioning or posture. When lifting heavy materials, the amount of force acting on the body and where it is concentrated depends on the lifter’s posture and lifting method. Improper lifting or carrying technique may result in excessive force acting on the back, which can cause injury.
    •   Continuous or excessive vibrations. During operation, powered hand tools often generate vibrational force. When used for significant amounts of time or under the wrong circumstances (e.g., in cold environments or by personnel with poor blood flow), the vibrations can cause muscular disorders, muscular spasms, vascular constriction, and other vibration-induced issues.   
    •   Constant or extreme force. The National Institute for Occupational Safety and Health (NIOSH) recommends personnel lift no more than 51 lbs. However, many industry professionals regularly lift more than the recommended amount in their day-to-day activities. These heavier loads cause strain on the body.
    •   Repetitive movement. Operations involving repetitive movement continually put stress and strain on the same muscle groups. Over time, this can lead to inflammation, irritation, and other injuries.

    Faster Operations

    Material handling equipment allows workers to move supplies easily without resorting to manual methods. In doing so, it enables them to complete transportation and distribution operations much faster.

    Better Accommodation of OSHA Regulations

    OSHA regulations dictate safety requirements for workers. Ergonomic equipment generally integrates these standards to enhance worker and workplace safety.

    Common Applications of Material Handling and Lifting Equipment

    Material handling equipment is used to load and unload various military and defense supplies, including engines, tank components, maintenance platforms, cargo doors, wheels, motors, and castings. Some of the typical machines and systems employed for these operations include:

    • Common Applications of Material HandlingYard ramps: These ramps allow workers to move trolleys and wheeled pallets between different heights, such as between a truck and the ground. Without these ramps, workers would have to make repeated lifting and twisting motions that could stress their backs, necks, shoulders, arms, and legs.
    • Drum handling equipment: Product stored in barrels, drums, and other containers typically require transportation or movement to other areas. Using specialized equipment designed for gripping, lifting, and dumping them reduces the risk of injuries related to tugging, lifting, and picking.
    • Tank lifts: Cylindrical tanks are often moved with a two-wheeled dolly. However, improperly secured tanks can fall off and injure the tank’s contents and the operator. Lifting devices with a securing mechanism facilitate safer transportation and lifting operations.
    • Manipulators: Floor-mounted manipulators with articulating arms are often used to pick and place products to build up pallets. Using vacuum cups or gripping arms to lift materials reduces the amount of physical stress experienced by workers.
    • Maintenance platforms: Powered work platforms that adjust to different heights eliminate the need for workers to climb up and down ladders multiple times—often with tools and parts in hand—during maintenance operations.
    • Positioners: During maintenance or rebuilding operations, positioners allow heavy or bulky parts to be lifted and rotated into the proper position.

    How EH Positioning Systems Power the Aerospace Industry

    Every industry is feeling the crunch to be more efficient, but perhaps none are more stringent than the aerospace sector. Aerospace companies need to be able to easily access and store thousand of unique parts, each type with wildly different dimensions and storage condition demands.

    Static storage and pick shelving are basic solutions, but they take up a lot of space. More complex systems like AS/RS systems, carousels, and gravity flow picking racks are more efficient. Aerospace facilities need material handling and storage solutions that can enable the movement of heavy and high-frequency parts while also being able to handle a wide variety of sizes for tubing, plates, sheet metal, and channels.

    Advantages for Improved Efficiency and Productivity

    Ergonomic Solutions for the Aerospace IndustryInvesting in better equipment handling systems doesn’t just save companies on square footage. Smart solutions also reduce the risk of workplace injuries by automating many lifting and handling tasks. These systems include material handling equipment, portable lifts, and any other equipment used to lift or move materials and inventory.

    With more advanced material handling solutions in place, personnel can easily access vertical and lateral storage spaces and use machinery to move the actual equipment to its destination. Reducing workplace accidents increases employee productivity, reduces turnover, and also reduces the costs of paying for medical fees and temporary staff. It also lets people work faster throughout the entire day.

    Adding positioning tools to the system further increases its efficiency. These solutions allow workers to rotate airplane subassemblies, move them, and easily assemble or inspect the parts.

    Three key benefits of positioning systems specifically include:

    1. Consistent quality. Automated positioning machinery enables accurate, precise, and consistent movements. This ensures that the resulting assemblies and product placements are also accurate.
    2. Increased efficiency. With automated equipment, setup and positioning are faster. It also requires fewer trips to storage shelves to gather all of the necessary components for each assembly. EH systems create even more efficiency because they reduce the amount of direct labor per assembly.
    3. Work flexibility. Smart automated equipment can be trained and retrained on more than one task. It requires less lead time between function changes and can handle more discrete projects or assemblies.

    Common Applications

    The aerospace industry has unique demands that must be considered when sourcing material handling and lifting equipment. These demands include the size of very large and heavy aircraft components, the weight of assembled parts like jet engines, and the complexity of electronic configurations. Some of the most common applications of specialized EH positioning systems include:

    • Equipment to carry jet engines from storage to test cells, such as high-travel lifts and heavy-duty ram lifts
    • Lifting, inspecting, and working on large components
    • Lifts that provide cantilevered work platforms along fuselages
    • Lightweight lifts for manual positioning
    • Platform lifts to position jet engines in recessed pits for inspections and work
    • Portable hydraulic lifts that give workers access to various vertical points along jet fuselages
    • Portable hydraulic tables to carry satellites between storage and launch sites

    The Benefits of EH Positioners

    eletric-hydraulic positionersElectric hydraulic (EH) positioners use electric hydraulic pumps and cylinders to create safe and efficient ergonomic lifting processes. One of the most significant benefits provided by EH positioners over alternative devices is the ability to lift and rotate large components or materials. This one capability can widen a facility’s manufacturing capabilities.

    Other benefits include greater durability for equipment, flexibility and versatility in general lifting processes, and greater safety for workers at and around the workstation.

    The Advantages of Electric-Hydraulic Power

    EH positioners offer a range of advantages, such as:


    Every workplace needs to consider ergonomics and safe handling when considering new equipment for their facilities. Correctly applied ergonomic choices can reduce the number of injuries, repetitive stress injuries, and potential liabilities.

    Creating a more comfortable work environment for employees also boosts employee morale, productivity, and length of employment terms. Ergonomic EH positioners allow employees to operate heavy duty machinery and complete tasks in more comfortable and healthy positions.

    Controlled Lifting Speeds & Higher Load Capacities

    Safety is equally as important as ergonomics, if not more.


    Unidex’s ergonomic EH positioners can be customized to fit certain tasks. This customization improves task completion times for a greater overall rate of efficiency. EH positioners also fit in constricted areas, so more units can safely share a limited work floor.

    The system that’s implemented at the beginning of construction can be customized to meet both functional requirements and simplicity requirements.

    The ergonomic aspect of EH positioners also leads to increased efficiency. Operators are more comfortable and less likely to experience repetition-related or equipment-related injuries, so the regular pace of completing work will face fewer interruptions.


    Dual EH positioners may be used together to create a positioning system with multiple set controls and actions. They can share a single hydraulic pump so each station can handle multiple routine actions. EH positioners feature a full range of motion—they can rotate 360° to lift or rotate complete workstations. They also feature high loads and the positioner itself has welded steel components that facilitate a long service life.

    Custom Equipment for Versatile Applications

    Operators can use EH positioners in a variety of industries and for multiple applications, though they’re typically reserved for heavy duty tasks. Some common applications include:

    • Lifting dump truck wheel rims
    • Manipulating the orientation of aircraft components for assembly
    • Material handling on shop and sales floors
    • Moving loads and empty skids in a warehouse
    • Rotating, powering, lifting, and spinning jet engines for repairing, assembly, and inspection

    EH positioners can be used in any industry or facility where workers need to transport, lift, or manipulate heavy loads.
