Explosion-proof electric chain hoist transformer How does it work?

Explosion-proof hand chain hoist emergency stop switch: When proof electric hoist button is pressed, the power will be cut off, the button lock automatically. Reverse protection circuit design ensures that when the motor power and avoid a wrong phase, does not result in the motor burned. Explosion-proof electric chain block and safety tongue, hook is highly resistant steel forged and heat treated to meet the needs of intensity levels under the hook can be rotated 360 degrees, and with a safety hook tongue in order to ensure the safety of Ascension when. Mechanical load brakes, mechanical load brakes at full load does not result in a fall faster and faster, and is independent of the motor brake, mechanical load brake effect still makes load at a slow rate slowly decreased.
