    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.
