To reduce load rotation and danger, we developed a suspender device activated by gyroscopic moment and applied it to construction work, finding that transport time of a hanging load was reduced and more comfortable and work without load rotation safer compared to conventional methods. Since characteristics of loads and restriction of work conditions vary at construction sites, the suspender device was not always suitable. To apply the device optimally, we improved the original device with new functions and the ability to handle larger loads. We describe new functions and applications and explain the device’s effectiveness and efficiency.
