| Electric motor lifting device: A lifting device consists of an electric motor, a gearbox and a drum with a cable for lifting a mass. Overload safety couplings are used to reduce electric screw jack and motorized screw lifting system damage, repairs and downtime by acting as torque limiters and overload protection. In the event of excessive torque the safety function disengages and the motor gets separated from the motorized screw jack drive system. Overload safety couplings are a life insurance for electric and motorized screw jack or lifting systems, no matter whether the error is due to incorrect operation, faulty programming, material overload or tool breakage. | |||||||||
