What safety issues should be paid attention to when lifting heavy objects with a crane?
When a crane is lifting heavy objects, safety issues are of vital importance, and operating procedures and safety requirements must be strictly followed. Here are some key considerations: First, before the operation, special commanders and operators must be designated, and it must be ensured that they have relevant training and qualifications. At the same time, the safety of the lifting slings should be checked and confirmed, including whether the hook safety buckle is effective, whether the wire rope has broken wires and strands, and whether the U-shaped ring has the risk of slipping and tripping. In addition, the implementation of safety measures and the safety of the lifting environment should be confirmed, and the safety of the lifting area should be checked, such as whether there are obstacles and whether the warning area is properly set.
During the hoisting process, the safe operating procedures for lifting operations must be followed. This includes using the correct command signals to ensure that other operators are clear about the safe operating procedures and command signals for hoisting. During the hoisting process, if a fault occurs, it should be reported to the commander immediately. In addition, the bundling requirements for the hoisted objects should be implemented in accordance with relevant regulations to ensure that the bundling is firm and reliable.
At the same time, the operator of the crane must undergo special training and hold the corresponding operation certificate. When operating the crane, the operating procedures must be strictly followed, the rated load of the crane must not be exceeded, communication must be kept open, and the actions during the hoisting process must be closely coordinated. In particular, it should be noted that the hoisted objects are strictly prohibited from falling freely, and the handbrake or footbrake should be used to control the slow descent to ensure stability and safety.In addition, the operating environment of the crane is also an important factor affecting safety. The operating area should be reasonably planned to ensure that there are no obstacles during the operation. When the crane is operating, it is strictly forbidden for anyone to stay, work or pass under the boom and the hoisted objects. Especially in open-air environments, if there are severe weather such as strong winds above level 6, heavy rain, heavy snow, and heavy fog, the hoisting operation should be stopped.
Finally, after the work is completed, the crane should be maintained and repaired in time to ensure that it is in good working condition. At the same time, any safety problems or hidden dangers that arise during the operation should be reported in time and appropriate measures should be taken to solve them. In summary, the safety issues that need to be paid attention to when the crane is lifting heavy objects involve many aspects, including personnel qualifications, equipment inspection, operating procedures, working environment, and maintenance after the work is completed. Only by fully considering and strictly complying with these requirements can the safe and smooth progress of the lifting operation be ensured.
