Tower crane rental operators to understand the tower crane common failure emergency treatment

When using tower crane rental equipment, operators often encounter some glitches. If operators do not know how to solve these problems, then not only a waste of time, but also a certain impact on the construction time.

 

The following Xiaobian tell you about what are the common failure tower crane and different solutions to the problem, I hope you can have some help:

 

1, tower crane foundation sink, tilt

 

Emergencies in this case: (1) should immediately stop the operation, and lock the slewing mechanism to limit the rotation (2) According to the situation to set the anchor to control the tower crane tilt.

2, tower crane balance arm, boom arm

 

(2) According to the emergency plan, adopt the means of welding and other means to reinforce the tower crane structure, or connect the tower crane structure with other objects by the connection method to prevent the tower crane Tipping and disassembling during the accident. (3) 2-3 2-3 tonnage crane, a lock boom, a lock balance arm.One of the arm in the balance when the role of torque, to prevent the force (4) according to the emergency program in the order specified, the jib or balance arm connector in the deformation of the connector removed, cut with gas welding, with a crane arm removed; The normal demolition tower crane tower crane will be demolished, deformation structure with steam welding open.

3, tower crane tipping over

Emergence of such emergency measures: (1) to take welding, connecting methods, without undermining instability increased under the balance of torque to control the development of the crisis. (2) use the right amount of tonnage crane crane in accordance with the rescue plan to demolition of the tower crane, deformation of components Gas welding cut or adjusted.

4, the anchor system danger

In case of emergency measures: (1) the tower balance arm corresponding to the building, the arm process to be smooth and locked (2) the tower crane anchoring system reinforcement (3) If you need to change the anchoring system components, the first After lowering the tower crane to the required height, replace the parts.

 

5, the tower structure deformation, fracture, open welding

 

Emergence of emergency measures in this case: (1) the tower balance arm corresponding to the deformation, the arm process to be smooth and locked (2) according to the circumstances using welding and other means, the tower crane structure deformation or fracture, open welding site Reinforced. (3) Drop the tower to replace the damaged structure.

 

In fact, for the tower crane leasing such equipment, the emergence of any accident will pose a security risk, so the tower crane equipment operators, we must be able to handle crane accidents.
