Sitema (Rockford, IL) has introduced the safety catcher, which stops and locks a dropping platen via a wedge mechanism located on a smooth rod that can be placed in any position and that is activated by the weight of the dropping mass. Installing the safety catchers on hydraulic presses and other machines in which dropping masses are a concern can eliminate dangers, says the company. Infinite position locking is an advantage. These safety catchers lock the mass to a smooth round bar. The safety catchers can be on any machines in which dropping masses must be stopped for safety reasons, including vertical-axis devices of machine tools, portals, and material handling systems.
