The crane hook group needs to pay attention to the following matters when working:

1. Inspection before use

Appearance inspection: Carefully inspect the appearance of the hook group to see if there are cracks, deformations, wear, etc. Especially if the dangerous section of the hook is found to be cracked or worn beyond the prescribed standards, it should be stopped immediately and replaced.

Opening degree inspection: Measure the opening degree of the hook to ensure that it is within the specified range. If the opening is increased, the hook may be decoupled during the lifting process, posing a serious safety hazard.

Rotational flexibility inspection: Check whether the rotating parts of the hook are flexible, such as hook shafts, pulleys, etc. If the rotation is not flexible, it may affect the stability and safety of lifting, and it should be lubricated or repaired in time.

Inspection of anti-decoupling device: Ensure that the anti-decoupling device of the hook group is intact and effective. The anti-decoupling device can prevent the hook from accidentally decoupling during lifting and is an important component to ensure safety. Check whether the spring of the anti-unhooking device is normal and whether the buckle is firm.

2. Correct installation and connection

Installation position: The hook group should be installed on the lifting arm or lifting mechanism of the crane. The installation position must be accurate to ensure that the hook can lift heavy objects vertically. When installing, follow the crane's instruction manual to ensure that the installation is firm and reliable.

Connection method: The connection between the hook group and the crane should adopt a reliable connection method, such as pin connection, bolt connection, etc. The connection parts should be checked regularly to ensure that the connection is firm and there is no looseness. During the connection process, it is necessary to pay attention to the center of gravity of the hook group matching the center of gravity of the crane to ensure the stability of lifting.

3. Precautions for lifting operations

Lifting weight limit: Lifting operations are strictly carried out in accordance with the rated lifting weight of the crane and the load-bearing capacity of the hook group, and no overloading is allowed. Before lifting, it is necessary to understand the weight of the heavy object and determine whether it can be lifted safely based on the performance parameters of the crane. If it is overweight, it may cause serious accidents such as the hook set to break and the crane to overturn.

Lifting angle: When lifting heavy objects, keep the center of gravity of the hook and the heavy object on the same vertical line to avoid diagonal lifting. Inclined hanging will cause the hook to bear additional lateral force, increase the load on the hook group, and easily cause the hook to break or decouple. At the same time, the cable-stayed crane will also affect the stability of the crane and increase the risk of accidents.

Lifting speed: The lifting speed must be controlled during the lifting process to avoid being too fast or too slow. If the lifting speed is too fast, the weight may swing too much and increase the risk of collision; if the lifting speed is too slow, the work efficiency will be affected. During the lifting process, the lifting speed must be reasonably adjusted based on factors such as the weight, shape, and lifting environment of the heavy object.

Smooth lifting: Keep steady when lifting heavy objects and avoid sudden starts or stops. Sudden start or stop will cause the heavy object to generate inertia force, increase the load of the hook group, and easily cause the hook toBroken or unhooked. During the lifting process, start and stop the crane slowly to ensure the stability of the lifting.

IV. Things to note in the working environment

Severe weather: In severe weather conditions, such as strong winds, heavy rain, lightning, etc., the crane hook set should be stopped from use. Strong winds may cause heavy objects to swing too much, increasing the risk of collisions; heavy rain and lightning may affect the crane's electrical system, leading to safety accidents.

Narrow space: When performing lifting operations in a narrow space, pay special attention to the distance between the hook group and surrounding objects to avoid collisions. During operation, pay close attention to the surrounding environment to ensure lifting safety.

High temperature environment: When working in a high temperature environment, pay attention to whether the material properties of the hook group are affected. High temperatures may reduce the strength of the hook set and increase the risk of breakage. When working in a high temperature environment, the hook set must be inspected and maintained regularly to ensure its safety and reliability.

5. Maintenance

Regular inspection: Regularly inspect the hook group, including appearance, opening, rotation flexibility, anti-decoupling device, etc. The inspection cycle should be determined based on factors such as the frequency of use of the crane and the working environment, and is generally once a month or once a quarter.

Cleaning and lubrication: Keep the hook set clean and remove dirt and debris on the surface of the hook in a timely manner. Regularly lubricate the rotating parts of the hook set, such as hook shafts, pulleys, etc., to reduce wear and extend service life.

Maintenance and replacement: If the hook set is found to be cracked, deformed, worn, etc., it should be repaired or replaced in time. Maintenance must be carried out by technicians to ensure the quality of maintenance. When replacing the hook set, choose products that meet the standards and install them according to the correct installation method.
