Structure and Working Principle of Construction Winch

There are mainly four parts for a construction winch: electric motor belongs to drive device, reducer is used to reduce speed, spooling device is used to make the rope or cable wind on the drum evenly and orderly, and the drum is used to wind the rope or cable, including letting in and out of the cable or rope as needed. These four parts are connected with gear or coupling to transfer torque.

The electric motor provides power, connect with input shaft of the reducer through coupling and input the power to the reducer. The reducer go through the output shaft via two-lever deceleration, transfer the power to the shaft of rope arranging device through the coupling, rotation of the gear on the shaft drives the parts on the drum to rotate and then the drum rotates. The spooling device is installed on the spooling shaft and it makes the wire rope wind on the drum evenly.

Safe Use and Operation of Construction Winches

1. The electric winch used for construction should be installed in the place with good view and far away from dangerous operation area; the installation of the winch should be firm and secure.
2. The wire rope should be arranged on the drum in good order. During the work, no one is allowed to pull, step on and cross the rope, or stop under the lifted materials.
3. The electric winch motor should be with separate operating switch, and equipped with overload and short-circuit protection device; its metal casing should be reliably grounded to keep safe and secure.
4. After finishing the installation, no-load test, dynamic loading test and overloading test should be carried out in accordance with standards.
5. Before using the winch for lifting or hoisting, it is necessary to check the winch, wire rope, ground anchor and other parts and accessories to make sure they are all in good working condition.
6. Whiling operating the construction winches, the operators should concentrate and see signals clearly and follow instructions. During the work, the operators cannot leave. The heavy loads should be lifted or lowered smoothly to avoid sudden lifting or lowering. If the temporary overhead stop is requested, both brake and ratchet wheel are needed to guarantee the safe operation.
7. If power failure happens suddenly during the operations, the power supply should be cut firstly, and then control the brake to lower the objects to the ground slowly.
8. The electric winch used for construction cannot be overloaded or used to hoist the objects that are heavier than the rated load of the winch.
