Tower crane's common faults and emergency deal
 
Tower crane in outdoor work process will often encounter a variety of small fault, if we know about the causes of these failures are not very, there was no way to timely find out the solution, not only waste the time, also reduces the efficiency of our work. Below small make up to you to introduce what are the common fault of tower crane and the solution of different fault, hope can help to you:
1, tower crane foundation subsidence and tilt
Appear this kind of circumstance of the emergency measures: (1) should immediately stop operation, and to lock slewing mechanism, to limit its rotation. (2) set the anchor according to the circumstance, control of tower crane.
2, balance arm of tower crane, crane boom boom
Appear this kind of circumstance of the emergency measures: (1) the tower crane can't do any action. (2) according to the emergency rescue plan, welding methods according to the circumstance, the tower crane structure reinforcement, or use the connection methods will tower crane structure linking with other object, to prevent the tower crane tilting and accidents in the process of demolition. (3) in 2-3 moderate tonnage crane, a lock hoist boom, a balance arm lock. One of them in the purpose of balancing moment when disassembling arm, prevent due to force a sudden change in the tilting. (4) order, as stipulated in the rescue plan will lift arm or balance arm fittings fittings removed, the deformation in gas cutting, arm off with a crane;(5) according to the normal of the demolition of the tower crane tower program, use steam hange in deformation of structure.
3, tower crane overturning
Appear this kind of circumstance emergency measures: (1) welding, connection methods, without destroying the buckling stress increase the balance torque, control the focal point. (2) choose a suitable amount of tonnage crane of the demolition of the tower crane in accordance with the emergency plan, open or adjust the gas welding deformation components.
4, anchor system danger
Will appear this kind of circumstance of the emergency measures: (1) balance arm is corresponding to the tower building, derrick process smoothly and locked. (2) the tower crane reinforcement anchoring system. (3) if you want to change the anchoring system components, tower first drop to a certain height, the replacement parts.
5, the tower structure deformation, fracture, open welding
Will appear this kind of circumstance of the emergency measures: (1) balance arm tower parts, corresponding to the deformation process of jib to smooth and locked. (2) the welding methods according to the circumstance, the tower crane structure deformation or fracture, open welding area reinforcement. (3) the drop tower replacement of damaged structure.
Saw the introduction of the above, you must in a similar situation next time, will know how to deal with. Thank you for coming on this site, my company is in line with "customer first, honesty first" principle, with a number of enterprises established long-term relations of cooperation.
