1. The personnel who participate in the lifting and hoisting operations, including drivers, crane workers, signal commanders, electric welders, etc., should all be special operators, and must be professionally trained, evaluated and qualified, and confirmed by physical examination to perform high-altitude operations .
2. The site should be surveyed in detail before lifting and lifting operations, and a special construction plan should be prepared according to the characteristics of the project and the operating environment, and approved by the technical person in charge of the company. The basis for the selection of the model, the design calculation of the lifting bar, the design of the ground anchor, the selection of the design of the wire rope and rigging, the ground endurance and the requirements of the road, the location map of the component stacking and various protective measures during the lifting process.
3. The lifting appliances should be inspected and accepted after entering the site. The reassembled lifting appliances should be tested according to the regulations, including static load and dynamic load tests, and the sensitivity and reliability of various safety devices should be tested. After assembled according to the plan, the picking rod should be tested by test hanging to confirm that it meets the requirements before it can be used.
4. In addition to regular maintenance according to the regulations, the truck crane should also carry out regular operation tests every year, including rated load and overload tests, to check its mechanical properties, structural deformation and load capacity.载 使用。 Use.
5. Lifting rigging slings should be checked and accepted piece by piece according to the design requirements of the construction plan before use.
6. The road on which the crane is running should be inspected, and subgrade measures such as roadbed boxes should be adopted when the ground endurance requirements are not met.
7. Materials such as materials for lifting and lifting various protective measures, erection of scaffolding, and enclosures in hazardous work areas should meet the requirements of the plan.
