A: Four main categories: normal tower crane with cat head, internal climbing tower crane, top less tower crane and luffing tower crane. 


Q: What kind of steel used for tower crane?

 A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.


Q: Your tower crane is similar to Potain or Liebherr type? 

A: We could develop any type of tower crane as per clients’ requirements if the clear information is provided. Originally, our tower crane design is based on Liebherr; but now, we not only introduced Potain design; but also developed special tower crane according to the market needs such as TC5013A with panel mast section. In addition, we also produce some models same as Potain original model, such as F0/23B, H3/36B and etc.

Q:Can the tower crane personnel install the construction elevator?
First of all, it is certainly impossible to install the elevator, because the tower and elevator certificate is not the same
Q:What are the safety devices for tower cranes?
Safety device for tower crane(1) lifting moment limiter, tower crane in lifting objects, the lifting radius and weight of the crane product is a constant number. According to this principle, a lifting torque limiter has been developed, the main function is to prevent overloading of the safety devices. The moment limiter only acts as a protection against the overload torque in the vertical vertical plane of the tower crane arm, and can not protect the tilting accidents caused by oblique hanging, wind load, rail inclination or collapse, etc..(2) weight limiter weight limiter's role is to protect the goods lifting weight does not exceed the maximum allowable weight of tower crane, tower crane is used to prevent the load exceeds the maximum rated load, avoid mechanical damage accident.
Q:How much height should tower crane work at M?
High building one meter high voltage line to keep the relevant national standard to ensure the forearm and the adjacent adjacent tower crane tower crane standard section has a safe distance of 2 meters, big boom high high tower mechanism area covering more than one meter, the end will need to receive from the nearest cab hook.
