The large hoppers of the wood chippers are filled with green waste from bushes, shrubs and trees by the personnel employed in gardening and landscaping. There is the risk that branches may become caught in the workwear resulting in the operators being drawn into the hopper of the chipper. In this situation, their hands are exposed to the greatest danger.
Previous safety devices are usually mechanical cut-outs that are fitted to machines at various points and require a great deal of presence of mind on the part of the employee to take effect in the event of an accident.
The electronic U-TECH Shred personal protection system has been optimised for use on chippers.
The transponder, which causes the shutdown of the machine in an emergency is not worn on the wrist but integrated into the ear protection so that the employee can continue to feed garden clippings into the hopper. If, however, he or she bends over the hopper too far and enters the danger zone with the ear protection, the chipper stops automatically. Injuries to the fingers, hands or arms by the brushwood chipper are thus avoided.
