CranesSafety in crane lifting operations is a crucial component of overall project safety. To ensure the safety of crane lifting operations, it is essential to operate in accordance with operational regulations. Specific precautions include:
1. Individuals involved in crane lifting operations, including drivers, crane operators, signal controllers, and welders, are all classified as special operations personnel. They must have completed professional training, passed the required examinations to obtain a qualification certificate, and been confirmed fit for high-altitude work through physical examinations.
Prior to crane lifting operations, a detailed on-site survey should be conducted. A special construction plan should be formulated based on the project characteristics and working environment, approved by the company's technical supervisor. The content should include: on-site environment and measures, project overview and construction techniques, selection criteria for lifting equipment, design calculations for crane jibs, ground anchor design, design and selection of wire ropes and rigging equipment, ground bearing capacity and road requirements, component storage and placement diagrams, as well as various protective measures during the lifting process.
Upon arrival at the site, lifting machinery should undergo inspection and acceptance. Reassembled lifting machinery must be tested according to regulations, including static and dynamic load tests, and the sensitivity and reliability of various safety devices should be tested. After the crane is assembled according to the plan, it should be tested for lifting to ensure it meets requirements before use.
4. In addition to regular maintenance and repairs as required, mobile cranes should undergo annual operational tests, including rated load and overload tests, to assess their mechanical performance, structural deformation, and load-bearing capacity. If they do not meet the specified requirements, they should be operated at reduced loads.
Before using lifting equipment, each piece should be inspected and approved according to the design requirements of the construction plan.
6. The crane's operating path should be inspected, and if it does not meet the ground bearing capacity requirements, measures such as subgrade boxes should be used for padding.
Section 7: The materials for various protective measures in lifting and hoisting operations, the construction of scaffolding, and the encirclement of hazardous work areas should comply with the requirements of the plan.
