The working principle and usage techniques of the Hand Cranked Hoist can be summarized as follows:

working principle

Hand cranked winches mainly drive internal transmission mechanisms such as gears or chains by manually rotating the handle (also known as a crank), thereby achieving the lifting, traction, or tensioning of heavy objects. Its working principle is based on the principles of mechanics, which converts human power into mechanical force to achieve the purpose of lifting or moving heavy objects.

Usage skills

security check:

Before use, a comprehensive safety inspection should be conducted on the hand winch to ensure its structural integrity, no damage, good lubrication of transmission components, and reliable braking device.

Check if the fixing device is secure and ensure that the winch will not loosen or fall off during use.

Correct installation:

Choose the appropriate model and specifications of hand cranked winch based on the weight of the heavy object to be lifted or moved and the working environment.

Install the winch correctly according to the instructions or professional guidance, ensuring its stability and reliable connection with heavy objects.

Operating standards:

During the operation, the handle should be rotated steadily and uniformly to avoid sudden acceleration or deceleration, in order to prevent impact on the winch.

Pay attention to the movement of heavy objects, adjust the operation direction and force of the winch in a timely manner, and ensure that the heavy objects move according to the predetermined trajectory.

Reasonable load:

Strictly adhere to the rated load limit of the winch, avoid overloading, and prevent damage or safety accidents to the winch.

If it is necessary to lift or move heavy objects beyond the rated load of the winch, larger or more powerful lifting equipment should be selected.

Maintenance and upkeep:

Regularly maintain the winch, including cleaning, lubrication, fastening, etc., to ensure that it is in good working condition.

If damage or malfunction is found in the winch, it should be repaired or replaced in a timely manner to avoid working with problems.

Emergency situation handling:

In case of emergency during operation (such as loss of control of heavy objects, winch failure, etc.), the operation should be stopped immediately and corresponding emergency measures (such as starting the braking device, cutting off the power supply, etc.) should be taken to ensure the safety of personnel and equipment.
