What conditions do you need to apply for a crane special operation certificate?

Two certificates are required to operate the crane, one is to run on the ground and need B2 driver's license, and the other is to operate the crane and obtain the certificate of People's Republic of China (PRC) Special Equipment Operator (mobile crane project).

7. If there are no maintenance facilities at the working edge or the maintenance height is less than 800 mm, main protective facilities must be set; The height of the protective railing in the horizontal working face is 1.2m, and the protective railing is closed with a safety net, or a skirting board with a height of not less than 180mm is set at the bottom of the railing.

8. When working at the height of the hole and the edge of the hole, protective facilities must be set up, including the edge of the pile hole, the edge of the groove and the edge of the hole reserved for installing equipment and pipelines. These are all formed by the construction technology.

9, smaller holes, should use a solid cover tightly, the cover should be able to prevent displacement; Large openings should be closed with safety net or cover plate, and protective railings should be set around the openings.

10, vertical hole on the wall (such as elevator wellhead and pipeline wellhead), except for protective railing or fixed gate at the wellhead, a flat net should be set every 10m in the shaft.

1 1. The ladder must not be raised for use. The bottom of the ladder foot should be solid and anti-skid measures should be taken, and the upper end should be fixed. When using the folding ladder, there should be reliable support measures.

12, operators are not allowed to climb up and down the specified passage, and they are not allowed to climb at will by using construction equipment such as elevator frames.

13, when aerial work is carried out in the surrounding air, there should be a solid foothold (such as scaffolding or working platform), and safety measures such as protective railings, hanging safety nets and wearing safety belts should be set according to the working conditions.

14, steel binding, skeleton installation work should be scaffolding. Do not use any construction equipment such as elevator frame to climb.

15, when pouring concrete more than 2m from the ground, an operation platform should be set up, and it is not allowed to stand on the formwork or support rod for operation.

16, cross construction should not be in the same vertical direction. The position of the lower operation should be outside the possible falling radius of the upper height. When the requirements cannot be met, a safety protection layer should be set up.

17, all kinds of demolition work (such as steel formwork, scaffolding, etc. ) shall not be cleaned at the same time; The temporary stacking place of materials shall be no less than 1m from the edge.

18, above the entrance and exit of the building, the entrance of the elevator and other places where people are concentrated,

Protective shed should be set up. The length of the protective shed should not be less than the provisions of the falling radius of objects with protective height.

19. Personnel involved in lifting operations, including drivers, cranes, signalmen, welders, etc. , should be a special operation personnel, must be a professional training and examination to obtain a certificate, and proved by experience to be able to work at heights.

20. Before the large-scale hoisting operation, the site shall be investigated in detail, and a special plan shall be prepared according to the engineering characteristics and working environment, and approved by the technical director of the enterprise. Its contents include: site environment and measures, general situation of the project and construction technology, selection basis of hoisting machinery, design and calculation of lifting arm, design and selection of ground anchor, design and selection of wire rope rigging, ground endurance and road requirements, arrangement of component stacking and various protective measures during hoisting.

2 1. After the hoisting machinery comes into the site and is inspected and accepted, the reassembled hoisting machinery shall be put into trial operation according to regulations, including static load and dynamic load tests, and the sensitivity and reliability of various safety devices shall be tested. After the suspender is assembled according to the scheme, it should be tested and used only after it is confirmed to meet the requirements.

22. In addition to regular maintenance in accordance with regulations, truck cranes should also be operated regularly every year, including rated load and overload tests, to check their mechanical properties, structural deformation and load capacity. If they fail to meet the requirements, the load should be reduced.

23, lifting rigging sling before use to check and accept the construction scheme design requirements one by one.

24, crane running road inspection, can't meet the requirements of durability of subgrade box and other bedding measures should be adopted.

25. The preparation of various protective measures, materials, scaffolding and enclosure of dangerous operation areas for hoisting meets the requirements of the scheme.

26. Conduct safety technical disclosure before hoisting operation, including hoisting technology, component weight and matters needing attention.

27, overload or object weight is not clear should not be operated; Don't operate objects with overload or unknown weight, such as lifting buried objects with unknown weight or tension, cable-stayed and inclined hanging; It is forbidden to stay when lifting; When there are people or floating objects on the hoisted object, it is forbidden to operate; Hanging heavy objects should be tied evenly and firmly, and padding should be added between the edges and corners of the heavy objects and the wire rope; When lifting, no one is allowed to pass above, and no one is allowed under the boom; Special hanging baskets must be used for lifting gas cylinders.

28, heavy vertical speed should be smooth, uniform, shall not suddenly brake; The left and right rotation should be balanced, and the reverse movement is not allowed before the rotation stops; When lifting at or near full load, it is forbidden to put down your arm or do two actions at the same time.

29, lifting objects should pull the rope, the speed should be uniform, it is forbidden to suddenly brake and change direction; When operating the controller, the operating direction shall not be changed directly.

30. When the crawler crane needs to walk with load, the load shall not exceed 70% of the allowable lifting weight, the walking road shall be solid and flat, the weight shall be in front of the crane, and the weight shall not exceed 500mm from the ground, and the rope shall be tied to drive slowly; Long-distance driving with load is prohibited. When the ground of the crane is soft and uneven, it is forbidden to lift two actions at the same time.

3 1. When two or more cranes lift the same heavy object, the wire rope should be vertical; The lifting and operation of each crane should be synchronized; The load borne by each crane shall not exceed the rated lifting capacity of each place. If the above requirements cannot be met, the rated lifting weight shall be reduced to 80%; The rated lifting capacity can also be reduced by the chief engineer according to the actual situation. When hoisting, the chief engineer should be present to guide.

32, crane in safety protection device failure, failure or inaccurate when it is forbidden to work in spite of; During operation, it is forbidden to repair, maintain and adjust the transmission part, moving part and the area where the moving part is located; The transmission part should be well lubricated.

33, in the open air in case of more than six winds or heavy rain, heavy snow, fog and other bad weather, should stop lifting operations. After the rain and snow, before the operation, try hoisting first, and then make sure that the brakes are sensitive and reliable before the operation.

34, when the high lifting operation or the driver can't see the job site or signal, signal transmission personnel. Adequate lighting equipment should be set in the workplace with insufficient light or at night.
