Steps to operate the Lifting Clutch

In actual operation, the Lifting Clutch is very flexible and easy to use. Its T-slot design enables it to easily engage with the head of the dog bone lifting anchor, ensuring stable load transfer and operational safety.

Coupling

The coupling operation is the most basic and critical step in using the Lifting Clutch. It is necessary to ensure the correct matching of the anchor and the lifting device. The following are the detailed steps:

Check the load capacity: 

Before operating, first check whether the load capacity of the anchor meets the lifting requirements. The Lifting Clutch has a clear load limit, so under no circumstances should the load limit of the anchor be exceeded, otherwise it may cause equipment damage or cause safety hazards.

Engagement device: 

When connecting the Lifting Clutch to the anchor, first push the opening of the spherical head down onto the ball head of the anchor. At this time, ensure that the anchor is fully entered into the opening of the spherical head and is in close contact with the body of the clutch.

Fixing:

Rotate the tongue at the bottom of the ball head downward so that it tightly surrounds the anchor. This process ensures a secure connection between the Lifting Clutch and the anchor, providing the necessary stability when the load is lifted. After securing, the clutch is ready for lifting operations.

During this process, it is crucial to keep the connection clean and free of obstructions. Any foreign matter or dirt may cause a poor connection, which in turn affects the safety of the equipment.

Lifting

Lifting operation is one of the core functions of using the Lifting Clutch, which can cope with a variety of different loads and operating environments. The following are the main steps and precautions for lifting operations:

Axial load and tilting operation:

The Lifting Clutch is designed to handle axial loads and allow limited tilting operations during lifting. This design provides workers with flexibility and can better adapt to complex construction environments.

Rotation operation: 

During the tilting operation, the Lifting Clutch can rotate on the lifting chain, which allows workers to be more flexible when handling precast panels. The rotation operation needs to be carried out under the premise of ensuring that the tongue is closed to avoid load instability.

Load release control: 

During the lifting process, the balancing function of the tongue ensures that the spherical head remains in the correct position, even when the load is released. The design of the tongue allows operators to better control the equipment and reduce unexpected operating errors.

Lubrication: 

During the rotation operation, if the rotation is difficult due to friction, grease can be used in moderation to improve the smoothness of the operation. However, lubrication should be used with caution to prevent excessive slippage or loss of control.

Release

After the lifting operation is completed and the load is safely placed, the Lifting Clutch must be released correctly to ensure the safety of the equipment and the smoothness of the next use. The steps of the release operation are as follows:

Release the load: 

When the load has been unloaded, the tongue can be turned to the release position by rotating the spherical head. This operation needs to be performed under the condition that there is no load, otherwise it may cause damage to the equipment or cause safety hazards.

Remove the equipment:

After releasing the Lifting Clutch, it needs to be completely removed from the anchor to prevent it from swaying in the air or uncontrolled contact with other equipment or workpieces.

Through standardized operating procedures, every use of the Lifting Clutch can be ensured to be safe and efficient, and its service life can be extended.

How to choose the right Lifting Clutch supplier

When choosing a Lifting Clutch supplier, you need to consider several key factors to ensure that the products and services provided by the supplier can meet the needs of the project. The following are the main considerations when choosing a supplier:
