The electric chain hoist is equipped with a safety clutch, when the lifting load exceeds 1.5 times times the rated load, the electric chain hoist safety clutch will skid, protects the hoisting mechanism not to damage. For example, the Elk type chain electric hoist is fitted with a safety clutch on the second-stage transmission gear. The skid torque of the safety clutch is adjusted to 1.5 times times the rated moment, the skid torque is large, then the safety clutch does not skid when the load is more than 1.5 times times the rated load, the safety protection function is lost, and the skid torque is small, then the load rated loading can not work normally.
Shell: The shell is lightweight and strong, the heat dissipation rate is high, the whole sealing design is suitable for use in the environment with poor working conditions.
Reverse phase protection device: for special electrical device, when the power wiring is wrong, the control circuit can not work.
Limit switch: Heavy lifting hanging under the limit switch device, so that the motor automatically stop to prevent the chain beyond, to ensure safety.
24v/36v device: When in operation, if the switch leakage, can prevent accidental accident occurred.
Braking device: This device can be realized in the power cut off instantaneous braking.
Chain bag: Lightweight, beautiful, durable. Chain: Adopt the imported FEC80 heat treatment alloy steel chain.
