Automatic electric safety for lifting machinery

摘要

The safety (10) is for handling machines where the load (2) is moved by a manipulator (5) suspended at the end of an articulated arm (1). The load is held by jaws or another type of gripper. The safety is suspended at the end of the lift and supports the manipulator. It has a fixed body (11) mounted at the end of the arm (3). There is a contactor (15) in the circuit which controls the opening and closing of the gripper. There is a moving contact (16) which moves inside the fixed body (11) supporting the manipulator.
