I. Matters needing attention
1. Confirm the lifting scope and safety factors.
Before hoisting operation, the scope of operation must be made clear to ensure that relevant personnel understand and abide by safety regulations. The hoisting site should be flat and have sufficient bearing capacity to avoid problems such as ground depression or inclination. In addition, the safety of lifting tools and equipment and possible risk factors, such as wind and humidity, should also be considered.
2, choose the appropriate lifting tools and equipment.
Select appropriate tools and equipment according to the actual situation of hoisting operation, such as cranes, slings, support frames, etc. Ensure the equipment is in good condition, and carry out inspection and maintenance according to regulations. In addition, the load and lifting speed should be reasonably configured to avoid overloading and dangerous situations.
3, in accordance with the provisions of the operation and monitoring
During the hoisting operation, it must be carried out in accordance with the specified operation flow to ensure that the hoisting process is stable and undisturbed. At the same time, we should always pay attention to the running state and load of the equipment, and take corresponding measures once abnormalities are found. In the process of operation, it is necessary to monitor the site in real time to ensure the safety of the surrounding environment and prevent accidents.
Second, the safety measures
1. Formulate special hoisting scheme and safety measures.
Before hoisting operation, a detailed hoisting scheme must be made, and the operation steps and safety measures must be defined. The plan should include risk assessment, safety precautions, emergency plans and other contents to ensure the safe and orderly lifting operation. In addition, the plan should be approved and accepted to ensure its scientificity and feasibility.
2. Strengthen on-site safety management and supervision and inspection.
In the process of hoisting operation, site safety management, supervision and inspection must be strengthened. First of all, it is necessary to ensure that relevant personnel have the qualifications and skills to engage in lifting operations, and understand and abide by safety regulations. Secondly, arrange the site reasonably to ensure the safety of the operation area without obstacles. At the same time, it is necessary to strengthen safety publicity and education to improve employees' safety awareness and self-protection ability.
Lifting operation without lifting.
1. There are people staying or walking under the boom and the hoisted heavy objects.
2, lifting command should be held by trained and qualified full-time personnel, no command or unclear signal.
3, steel, steel, pipe and other slender objects must be firmly hold, multi-point lifting. It is not allowed to hang a single head "one thousand catties" or bind it loosely.
4. There is no need to hang the perforated plate, ash hopper and hopper car at four o'clock or remove the external board of the large formwork. Precast reinforced concrete floors are not allowed to be hoisted in pairs.
5, hanging block must use safe and reliable block fixture, hanging block must use brick cage, and neatly stacked. Wooden bricks, embedded parts and other sporadic objects should be safely stacked in containers, and uneven stacking is not allowed for hoisting.
6, floors, girders and other hanging objects are not allowed to be lifted.
7, sheet pile buried in the ground, well point pipe, etc. , and adhesion, attached objects are not allowed to hang.
8. When working with multiple machines, ensure that the product weight is not less than 3m away from the side, and the multiple machines are working on the same track without safety measures.
9, more than six winds are not allowed to hang.
10, cable-stayed heavy objects or exceeding the allowable mechanical load.
