Countermeasures for the safest lifting operation

Countermeasures for safe lifting operation

1. Lifting operators must hold two kinds of work permits. Hoisting safety operation certificate shall be applied for objects with a hoisting quality greater than 10t

2. For objects with a lifting mass of 40t and the main structure of civil engineering, a lifting construction scheme should be prepared. Although the lifting object is less than 40t, the lifting construction scheme should also be prepared under the circumstances of complex shape, small stiffness, large length diameter ratio, precision and precious, and special construction conditions. The hoisting construction scheme can be implemented only after being reviewed by the competent construction department and the safety technology department and approved by the competent factory director or the chief engineer

3. Before all kinds of hoisting operations, safety warning signs should be set up at the hoisting site in advance, and special personnel should be assigned to monitor it. Non construction personnel are not allowed to enter

4. During the hoisting operation, there should be sufficient lighting at night. In case of heavy snow, rainstorm, fog and strong wind above level 6 during outdoor operation, the operation should be stopped

5. Hoisting operators must wear safety helmets, which should comply with the provisions of safety helmets (gb28ll 1989). When working at heights, the relevant provisions of the safety regulations for work at heights in the plant area shall be observed

6. Before hoisting operation, all kinds of machines and tools such as hoisting equipment, steel wire rope, wind rope, chain and hook should be checked to ensure safety and reliability, and they are not allowed to be used with diseases

7. During the hoisting operation, the division of labor must be clear, the post must be adhered to, and the unified command must be carried out according to the contact signal specified in the hoisting command signal (gb5082 1985)

8. It is strictly forbidden to use pipes, pipe racks, electric poles, electromechanical equipment after 23 years as lifting anchors. Without the examination and accounting of relevant departments, buildings and structures shall not be used as money points

9。 Before hoisting operation, detailed safety inspection must be carried out on the operating parts, safety devices, slings and riggings of various hoisting machinery, and the safety devices of hoisting equipment should be sensitive and reliable. Trial hoisting must be carried out before hoisting, and operation can be carried out only after confirmation

10. no one is allowed to go up and down with the hoisting heavy objects or hoisting machinery. Under special circumstances, if it must be lifted and lowered, reliable safety measures should be taken and approved by the on-site commander

11. If hot work is required at the lifting operation site, the relevant provisions of the safety regulations for hot work in the plant area shall be observed. The lifting rope and wind rope at the lifting operation site, the introduction of the manufacturer of Jinan gold testing material testing machine, the dragging rope, etc. should avoid the deformation of the same belt wire. Strengthening is one of the valuable properties of metal, which plays an important role in metal pressure processing and ensuring the safety of machine parts in case of occasional overload, and keep a safe distance

12. when using the finalized lifting machinery (crawler crane, tire crane, bridge crane, etc.) for lifting operations, in addition to complying with the general standards, the operating procedures of the finalized machinery should also be observed

13. During the hoisting operation, the hoisting must be carried out according to the specified load, and the slings and riggings shall be selected and used after calculation. Overload operation is strictly prohibited. When the hoisted weight is close to or reaches the rated lifting capacity, the brake should be checked. After the trial lifting with low height and short stroke, it should be lifted steadily

14. No one is allowed to stand, pass or work under the suspended load

15. In the lifting operation, one of the following situations is not allowed to lift:

(1) the command signal is unknown

(2) overload or unknown object mass

(3) oblique pulling of heavy objects

(4) the light is insufficient and the heavy objects cannot be seen clearly

(5) people standing under heavy objects, or heavy objects over the head

(6) heavy physics is underground

(7) the weight is not fastened firmly, and the rope is knotted and uneven

(8) there is no cushion for edge objects

(9) the medium in the container is too full

(10) safety device failure

16. During truck crane operation, in addition to strictly abiding by the relevant safety operation procedures of lifting operation and truck crane, the vehicle shall be kept in good condition, and it is not allowed to operate with diseases, so as to achieve driving safety

the potential danger of lifting operation is object strike. If the hoisted object is inflammable, explosive, toxic and corrosive materials, and if the sling is accidentally broken, the hook is damaged or the hoisted object falls in violation of the operating procedures, in addition to the possibility of direct injury, the packaging of the inflammable, explosive, toxic and corrosive objects will be damaged, and the medium will flow out, causing pollution, and even fire, explosion, corrosion, poisoning and other accidents. During the inspection and maintenance of the lifting equipment, there are dangers such as electric shock, falling from height, mechanical injury, etc. the truck crane has the potential to cause traffic accidents during the driving process. 3A composites/airexbaltekbanova revealed the detailed dangers of its contribution to the new Agena Marin taxi catamaran
