Use of Tower Crane


Main points of Tower Crane operation

1. Before tower crane operation, the following inspection and commissioning should be carried out: (1) track foundation should be straight without subsidence, joint connection bolts and track nails should not be loosened; (2) safety devices, transmission devices, indicators, main parts of connection bolts, wire rope wear, power supply cables and so on must comply with relevant regulations; (3) according to relevant regulations. Conduct test and commissioning.

2. When there are more than two cranes in the same construction site, the distance between the two cranes should not be less than 2m. 3. Before the hoisting hook, lifting trolley or traveling cart run to the limit device, they should slow down to the stop position and keep a certain distance from the limit device (the hook shall not be less than 1m, and the traveling wheel shall not be less than 2m). It is strictly forbidden to use the limit device as the control switch for stopping operation.

4. Lifting, turning and walking of boom crane can be carried out at the same time, and amplitude variation should be carried out separately. After each amplitude change, the location of the amplitude change should be checked. When the load reaches 90% or more of the rated lifting weight, it is strictly forbidden to change the load amplitude.

5. Lift heavy objects and prohibit free descent. When the weight is in place, slow positioning mechanism or brake can be used to slow down the weight.

6. When lifting a heavy object to move horizontally, it should be over 0.5m higher than the obstacles it crosses.

7. Cranes equipped with upper and lower control systems shall not be used at the same time.

8. In case of Gale or gust above grade 6, the operation should be stopped immediately, the rail clamp should be locked, the brake of the rotary mechanism should be completely loosened, and the lifting arm should be able to rotate with the wind. For light pitching Luffing Crane, the lifting arm should be lowered and locked together with the tower body structure.

9. In operation, when the operator leaves the control room temporarily, he must cut off the power supply and lock the rail clamp.

10. It is strictly forbidden for cranes to overload when loading special elevators. The rope breaking protection device must be reliable. When the crane is working, it is strictly forbidden to start the elevator. When the elevator is out of service, it should be lowered to the bottom of the tower body and not suspended in the air for a long time.
