What should we pay attention to when the crane hook group is working?
The following things to be paid attention to when working in the crane hook group: 1. Check before use
Appearance inspection: Carefully check the appearance of the hook group to see if there are cracks, deformation, wear, etc. Especially for dangerous cross-sections of the hook, if cracks or wear exceeds the specified standards, they should be stopped immediately and replaced.
Opening degree check: Measure the opening degree of the hook to ensure it is within the specified range. If the opening degree increases, it may cause the hook to be decoupled during lifting, which poses serious safety hazards.
Rotation flexibility check: Check whether the rotating part of the hook is flexible, such as hook shafts, pulleys, etc. If the rotation is inflexible, it may affect the stability and safety of the lifting, and lubrication or repair should be carried out in time.
Anti-decoupling device inspection: Ensure that the anti-decoupling device of the hook group is intact and effective. Anti-decoupling device can prevent the hook from accidentally decoupling during lifting and is an important part to ensure safety. Check whether the spring of the anti-decoupling device is normal and whether the snap is firm.
2. Correct installation and connection
Installation position: The hook group should be installed on the crane's crane's crane's crane's crane's crane's installation position should be accurate to ensure that the hook can lift heavy objects vertically. During installation, 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 inspected regularly to ensure that the connection is firm and there is no looseness. During the connection process, 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 strictly follow the rated lifting weight of the crane and the load-bearing capacity of the hook group, and must not be overloaded. Before lifting, you must understand the weight of the heavy object and determine whether it is safe to lift according to the performance parameters of the crane. If it is overweight, it may lead to serious accidents such as hook group breakage and crane overturn.
Highing angle: When lifting heavy objects, keep the center of gravity of the hook and the heavy objects on the same vertical line to avoid slanting and oblique hanging. The narrowly-staggered inclined lift will cause the hook to bear additional lateral force, increase the load of the hook group, and easily lead to the hook breaking or unhooking. At the same time, the narrowly-staggered inclined crane will also affect the stability of the crane and increase the risk of accidents.
Lifting speed: During the lifting process, you must control the lifting speed to avoid being too fast or too slow. A lifting speed that is too fast may cause heavy objects to swing too much, increasing the risk of collision; a lifting speed that is too slow will affect work efficiency. During the lifting process, the lifting speed should be adjusted reasonably based on factors such as the weight, shape and lifting environment of the heavy object.
Still steady lifting: Keep it stable when lifting heavy objects to avoid sudden start or stop. Sudden start or stop will cause the heavy object to produce inertia forces, increasing the load of the hook group, and easily causing the hook to break or decouple. During the lifting process, the crane should be started and stopped slowly to ensure the stability of the lifting.
4. Precautions for working environment
Severe weather: In severe weather conditions, such as strong winds, heavy rainstorms, thunder and lightning, the use of crane hook sets should be stopped. Strong winds may cause heavy objects to swing too much, increasing the risk of collisions; heavy rain and thunder may affect the crane's electrical system, resulting in safety accidents.
Narrow space: When carrying out lifting operations in a narrow space, pay special attention to the distance between the hook group and the surrounding objects to avoid collisions. During operation, you must closely observe the surrounding environment to ensure safety of lifting.
High temperature environment: When working in a high temperature environment, pay attention to whether the material properties of the hook set are affected. High temperatures may reduce the strength of the hook set and increase the risk of fracture. When working in high temperature environments, the hook group should be inspected and maintained regularly to ensure its safety and reliability.
5. Maintenance
Routine inspection: Regular inspection of the hook group, including appearance, opening degree, rotation flexibility, anti-decoupling device, etc. The inspection cycle should be determined based on factors such as the use frequency of the crane and the working environment, generally once a month or once a quarter.
Cleaning and lubrication: Keep the hook set clean and remove dirt and debris from the surface of the hook in time. Regularly lubricate the rotating parts of the hook set, such as hook shafts, pulleys, etc., to reduce wear and extend service life.
Repair and replacement: If the hook group is found to have cracks, deformation, wear, etc., repair or replacement should be carried out in time. The repair must be carried out by technicians to ensure the quality of the repair. When replacing the hook group, select a product that meets the standards and install it according to the correct installation method.
