When using an electric winch for lifting operations, a series of rigorous operating steps must be followed to ensure safety and efficiency, which can be divided into four stages: pre operation preparation, electric operation, power braking operation, and post operation maintenance. The following is a detailed explanation:

1、 Preparation before operation

Check the status of the winch:

Check the mechanical components of the winch, such as brakes, clutches, gears, etc., to ensure that they are in good condition and free from wear or damage.

Check the electrical system of the winch, including the motor, controller, cables, etc., to ensure that the connections are secure and free from damage or aging.

Check the wire rope of the winch to ensure that there are no broken wires, wear or distortion, and that it is firmly fixed.

Confirm load information:

Understand the weight, size, and shape of the load to ensure that they are within the rated lifting capacity of the winch.

Select appropriate lifting equipment and fixing methods based on the characteristics of the load.

Choose a suitable location:

Choose a stable and solid ground to place the winch, ensuring that it does not move or tilt during the lifting process.

Ensure that there are no obstacles around the winch so that it can be quickly evacuated in emergency situations.

Prepare safety equipment:

Wear personal protective equipment such as helmets, safety shoes, gloves, etc.

Prepare emergency stop devices and fire extinguishers and other safety equipment, and ensure that they are in an easily accessible location.

2、 Electric operation

Connect the power supply:

Connect the power supply according to the electrical diagram of the winch, ensuring that all connections are firm and reliable.

Check if the power indicator light is on and confirm that the power is connected.

Start the winch:

According to the winch operation manual, starting the motor is usually achieved by pressing the start button or turning the start switch.

Observe whether the running direction of the winch is correct and ensure that it is consistent with the lifting direction of the load.

Control the lifting speed:

Use a controller (such as a cam controller or frequency converter) to adjust the lifting speed of the winch.

Choose the appropriate speed gear based on the weight of the load and the lifting height, avoiding being too fast or too slow.

Monitoring operational status:

Pay close attention to the operating status of the winch, including parameters such as current, voltage, and oil pressure.

Observe the rise of the load to ensure it is stable and without shaking.

Parking operation:

When the load reaches the designated position, press the stop button or turn the stop switch to stop the winch.

Use the brake device to firmly fix the load in the designated position.

3、 Power braking operation (if applicable)

Prepare the braking system:

If the winch is equipped with a power braking system, ensure that it is properly connected and in standby mode.

Check if the brake power supply and brake contactor components are working properly.

Activate the braking system:

When the load drops or deceleration is required, press the brake button or turn the brake switch to activate the power braking system.

Observe the braking effect to ensure that the load can smoothly decelerate and stop.

Adjust braking parameters:

Adjust parameters such as braking current and braking time based on the characteristics of the load and the speed of descent.

Ensure that the braking system can provide sufficient braking torque while avoiding excessive braking that may cause load damage or winch failure.

4、 Post operation maintenance

Disconnect the power supply:

After completing the lifting task, disconnect the power supply of the winch according to the electrical diagram.

Confirm that all indicator lights have been turned off and the power supply has been completely cut off.

Check the status of the winch:

Check for any abnormalities or damage to the mechanical components and electrical system of the winch.

Clean the dust and dirt on the surface of the winch and keep it clean and dry.

Record the homework situation:

Record the load weight, lifting height, running time and other parameters of this lifting operation.

Record the operating status of the winch and any abnormal phenomena or fault information for subsequent analysis and handling.
