Ergonomic Lift Equipment -- Test
Test comparison. Subjects simulated high cycle and precision placement tasks typically performed with lifting devices. They were instructed to work as fast as reasonably possible while keeping their heart rate in a target region of 45 to 55% of their maximum heart rate, which is considered to be a safe working pace. Manual lifting required 78% more energy expenditure than with this G-Force ™ lift and the other lifting devices. Operators were an average of 68% more productive with the G-Force ™ while exerting approximately the same energy as with the other lifting devices.
Standing at an Assembly Line:
Ergonomic options:
If the environment is well designed, the worker can choose from among a variety of well-balanced working positions and change between them frequently. Working tables and benches should be adjustable in height to match the station to the worker's individual body size and the particular task. Adjustability ensures the worker can carry out work in well-balanced body positions. If the workstation cannot be adjusted,...
There should be enough room to move around and to change body position. Also, built-in foot rails or portable footrests allow the worker to shift body weight from one leg to the other. Elbow supports for precision work reduce upper arm and neck tension. Controls and tools should be easily reached without twisting or bending. Where possible, a seat should be provided so the worker can do the job either sitting or standing. It must place the worker at a proper height. For work that requires standing, a seat will allow the worker to sit occasionally. Seats at the workplace expand the variety of possible body positions and offer more flexibility. The number of muscles is increased, which equalizes the distribution of loads on different parts of the body. Thus, there is less strain on individual muscles and joints used to maintain the upright position. Changing body positions enhances the blood supply to working muscles and reduces fatigue. Footwear and flooring materials are also important factors
