Innophys (Hachioji City, Tokyo; President: Naotaka Otokawa) has delivered the “Muscle Suit Soft-Power” supporter-type assist suit to Yamaha Motor. It is being used to reduce the physical burden on workers in the management and shipping of repair parts.
By incorporating the artificial muscle assist technology developed in the Muscle Suit series into the back of the supporter, it achieves the strongest level of support among supporter-type suits. It reduces lower back strain by 35%. It is effective for tasks that place strain on the lower back, such as lifting and carrying tasks in manufacturing and logistics warehouses, maintaining uncomfortable postures in nursing care settings, and bending forward in agricultural work.
Yamaha Motor Co., Ltd.’s logistics warehouse manages and ships repair parts for motorcycles, marine products, electrically assisted bicycles, and power machinery, handling a variety of packages and weights on a daily basis.
One of the challenges specific to the company was that the shape and size of cargo varied widely, making many tasks impossible to handle with fixed support equipment such as lifting devices. Handling heavy loads in particular placed a great physical strain on workers, and improvements were needed in terms of safety and health.
