Hoisting refers to the use of corresponding mechanical equipment and facilities to complete structural hoisting and facility installation in construction projects. The operation is dangerous, and the operation environment is complex and technically difficult.
1. Before the operation, a special construction plan should be prepared according to the characteristics of the operation, and the plan and safety technology should be clarified to the participating operators.
2. Warning areas should be set around during operation, and eye-catching warning signs should be set up to prevent irrelevant personnel from entering; guarding personnel should be set up in particularly dangerous places.
3. Most of the hoisting operations must be operated by professional and technical personnel; personnel who belong to special operations must undergo special safety operation training in accordance with relevant national regulations and obtain special operation qualification certificates before they can start operations.
4. Operators should choose a safe location for on-site operating conditions. The hoist and ground pulley must pass through the area of the wire rope, and personnel are prohibited from standing and passing.
5. The hoisting process must be commanded by a dedicated person, and other personnel must obey the command. Lifting command can not be used as other types of work. It should also be ensured that the crane driver is clear and accurate and hears the command signal.
6. The operation process must abide by the principle of "Ten No Lifting" of the crane.
7. The binding requirements of the hoisted objects follow the requirements of the hoisted objects binding operation in the first section of the tower crane.
8. The component storage site should be flat and solid. The stacking of components should be leveled with square wood, which must be stable and not allowed to be ultra-high (generally not more than 1.6m). In addition to stows for component storage, corresponding supports should be provided when necessary to improve its stability. It is forbidden for irrelevant personnel to pass through the stacked components to prevent the occurrence of component collapse and crowding accidents.
9. In the open air, when there are strong winds above level 6, or heavy rain, heavy snow, heavy fog and other weather, the lifting operation should be stopped.
10. When the crane is operating, it is strictly forbidden for anyone to stay, work or pass under the boom and hanging objects. When lifting heavy objects, it is strictly forbidden for people to pass from above. Strictly prohibit cranes to carry people.
11. Precautions for frequently used lifting tools
⑴Manual rewinding: Operators should be trained and qualified before they can work. When hanging objects, they should be hung firmly and then slowly pull the rewinding chain, and do not pull it diagonally. When one person cannot pull, the reason should be found out, and multiple people are prohibited from pulling violently.
⑵Hand lifting hoist: Operators should be trained and qualified before they can work. Check the reliability of the self-locking clamp device before use. After the wire rope is clamped, it should be able to reciprocate, otherwise it is prohibited to use it.
(3) Jacks: Operators should be trained and qualified before they can work. The jacks are placed on a flat and solid ground with wood or steel plates to prevent ground subsidence. The top contact surface with smooth objects should be padded with hardwood to prevent sliding. At the beginning of the operation, the jacking should be gradually raised, pay attention to prevent the jacking, and always keep the balance of the heavy object
