hand help hero / Heavy-labour supporting device

hand help hero

The concept hand help hero (h3) is a system to support building labors at their tough work. „h3“ consists of a vest with integrated accumulators on the back and the arm-supporting unit. The h3-drill, which runs by power from the back, is an extension of the system and allows a new ergonomic way of triggering by just slightly depressing the flexible sidewalls of the handle. The usual weapon-like-trigger will be replaced. To support the arm an electronic-motor and an artificial muscle will be used. The main focus of the concept is on supporting the human and not relieve him of the work, because skills can only be trained by repetitions.
