The lifting operation of cranes requires attention to the following important safety matters:
First, Equipment Inspection
Before each operation, a comprehensive inspection of the crane must be carried out, including but not limited to:
1.The integrity and reliability of mechanical components, such as whether the hook has cracks or deformations, and whether the wire rope has broken wires or wear.
2.Whether the electrical system is normal, such as control buttons, indicator lights, etc.
3.The performance of the braking system is good to ensure timely braking in an emergency.
Second, Operator Qualification
1.Operators must undergo professional training and obtain the corresponding operation qualification certificates.
2.Be familiar with the performance, operating procedures and emergency handling methods of the crane.
Third, Environmental Assessment
1.Ensure that there are no obstacles at the lifting site, including in the air and on the ground.
2.Pay attention to the weather conditions. Severe weather such as strong winds, thunderstorms, etc. may affect the safety of lifting.
3.Understand the bearing capacity of the ground to prevent the crane from toppling due to ground subsidence.
Fourth, Preparation of Lifted Objects
1.Correctly bind and fix the lifted objects to prevent them from slipping during the lifting process.
2.Confirm that the weight of the object is within the rated load capacity of the crane.
Fifth, Signal Communication
1.There must be a clear and distinct signal communication method between the operator and the commander.
2.Ensure that the signal transmission is accurate and without errors to avoid accidents caused by misunderstandings.
Sixth, Operating Specifications
1.Start and stop the crane smoothly, avoiding sudden acceleration or deceleration.
2.Operate strictly in accordance with the operating procedures and do not operate against regulations.
Seventh, Equipment Maintenance
1.Regularly maintain and service the crane and replace worn parts in time.
2.Keep maintenance records to track the use and maintenance of the equipment.
For example, at a certain construction site, due to the operator not carefully checking the condition of the hook before lifting, the hook suddenly broke during the lifting process, and the heavy object fell, causing casualties and property losses. Another example is that in another factory, the lifting operation was not stopped due to bad weather, and the strong wind caused the crane to lose balance and tip over, resulting in a serious accident. These examples all highlight the importance of strictly abiding by the safety matters of lifting operations.
