What should be paid attention to when using electric winch?

The electric winch is driven by an electric motor, and the winch that drives the device to reverse the drum. The motor is able to control the speed through a frequency converter.

1. The equipment of the winch during construction is mostly temporary equipment, which is fixed on the ground anchor by using the reserved hole on the machine base or coiling the machine base with a steel wire rope. The weight iron is added to the rear of the base to ensure that the hoist does not slip, shift, or overturn during operation.

2. The steel wire rope should be led out from the bottom, and the middle of the drum should be perpendicular to the middle line of the first guide pulley at the beginning. The first guide pulley is not allowed to use open pulleys, and the pulleys should be fixed with ground anchors. on the shelf.

3. The distance between the pulley and the hoist should be at least 8-12 meters, and the hoist with more than 3 tons should be greater than 15 meters. The steel wire rope is wound to the middle of the drum, and its inclination angle is not allowed to exceed 1.5 degrees to 2 degrees.

4. In order to ensure the stability, when the lifting weight is at a lower position, the steel wire rope should not be fully released from the drum, except for the number of turns fixed by the pressure plate, at least 3 safety circles should be left.

5. The winch should be installed in a place with a slightly higher terrain, a good view, and a solid foundation. The winch of outdoor equipment should be protected from rain and smashing. Usually, a simple shed is set up. After the shed is set up, it should be ensured that the operator can see the lifting, falling and location of the hoisted objects.

6. The control system of the winch should be installed beside the driver. Make sure the setting is reliable and useful to prevent electric shock.

7. The driver of the winch should pass the training and check, hold a certificate to work, and set the machine and the person. Before operation, a test run should be carried out to check whether the braking equipment is flexible and reliable, whether the connecting fasteners are loose, whether the working conditions and safety equipment meet the requirements, and the vehicle is allowed to drive after confirming that it is correct.

8. It is forbidden to overload the winch, and the wire rope is not allowed to mop the floor during work. When passing through the passage, protective equipment should be added to prevent people from stepping on or pressing on vehicles, and it is forbidden for personnel to step over the working wire rope.

9. Matters needing attention when laying ground anchors: Necessary calculations should be made according to the pulling force of the cables when laying ground anchors, and the corresponding safety factor should be considered to make it have a satisfactory anchoring force. According to the accounting and embedding conditions, select the specifications and methods of ground anchors.
