Tower crane xx year work plan
1, continue to do a good job of tower crane lifting operations.
2, to strengthen the tower division, signaling command staff safety education.
3, arrange and organize the demolition of the tower crane.
4, strengthen the construction elevator, basket and other mechanical equipment safety management.
Without adequate planning and supervision, will lead to crane accidents, the resulting consequences can be disastrous, such as serious damage to property, and even cause casualties. A good lifting and hoisting operations plan can be very protective of the crane itself and of the people working near the crane.
The preparation of lifting and hoisting operations plan should be considered:
(1) to have a full understanding of their own conditions. Once it is determined that the need to use mobile cranes to lift loads, the lifting company needs to decide whether it has qualified personnel to prepare a safe operating plan for the lifting operation. Depending on the situation, you may choose to rent a crane for the lifting or contract out the lifting operation. Whether renting or contracting, a person needs to be appointed to take full control and responsibility for the planned lifting operation.
(2) visit the lifting site. The designated person needs to visit the planned lifting site to obtain all the necessary information, and thus a comprehensive understanding of the lifting operation requirements. A detailed and comprehensive written report on the load and the operation site is required after the visit, providing information on the type of load, its weight, dimensions, lifting points, the presence of concealments that affect the weight and stability of the load and that would be dangerous in the event of spillage, and the presence of collision hazards near the operation site and the condition of the ground at the operation site.
(3) Crane selection. The designated person should be very understanding of the crane, such as various types of crane lifting capacity and operating limits, crane operating mode, rated lifting capacity, crane specifications and weight and the calculated load of the outstretched leg. At the same time, the designated person and the crane supplier good relationship to obtain high-quality cranes and useful advice is essential.
(4) Lifting accessories are correctly selected and visually inspected before use.
(5) Staffing. The designated person can in some cases take on the responsibilities of the crane supervisor, the crane supervisor is responsible for carrying out the instructions of the designated person rather than giving instructions, one of the important roles is to stop the lifting operation when: do not understand what needs to be done lifting operation unplanned changes and doubts about the lifting operation and the safety of the people involved.
