Are the ratchet and pawl devices of the electric chain hoist and the chain hoist the same

The electric chain hoist has strong load-bearing capacity, fast operating speed, saves time and effort in lifting heavy objects, improves work efficiency, and has a high safety factor, making it less prone to heavy object falling accidents. Because there is a ratchet and pawl device in the system of the electric hoist, it will brake the lifting system in a timely manner in case of unexpected situations.

The working principle of the ratchet and pawl is that when the braking torque of the conical brake motor is insufficient or the transmission link is broken, causing the load to accelerate and decrease, the safety brake will have an emergency braking protection effect, triggering the ratchet to mesh with the ratchet, generating a braking mode, and the chain of the electric chain hoist will stop rotating accordingly. When the operator presses the lifting button again, the pawl will actively disengage from the ratchet under the tension of the spring, restoring the normal lifting function of the electric hoist.

The function of the ratchet and pawl is to avoid serious damage caused by the acceleration and descent of the load to the heavy object, protect the safety of lifting the heavy object and the safety of surrounding operators.

The ratchet and pawl equipment is not only a safety brake in electric chain hoists, but also a safety brake in operational devices such as chain hoists, fall arresters, and manual winches, effectively ensuring the safe operation of mechanical equipment.
