How the Hoisting Function Works
The electric motor rotates the axle, which makes the hoisting gear helical steps turn. The gear transfers the motor power to the hoisting chain which then moves according to the selected direction (up/down).
The assembly includes a slipping clutch that allows the lifting of loads corresponding to 110% of nominal SWL (safe working load) and prevents the lifting of loads that exceed 160% of the SWL. An overload slips the clutch, allowing the motor to continue running while preventing the gearbox helical steps (and hoisting chain) from moving.
Only use the emergency stop button to stop movement in the event of malfunction or other emergency situation. Using the emergency stop button can cause the load to swing unexpectedly.
