Product Description
Hammerhead Tower Crane
 QTZ125 (TC6018/6313/6515)

Flattop Tower Crane Qtz125 Construction

The QTZ125 hammerhead tower cranehas advanced technical parameters with a maximum radius of 60/63/65m and a maximum height of 181m with mast sections and anchorages. If customers need, we can design this self-erecting craneto reach 200m.

The hammerhead tower crane can come in stationary, external climbing and inner climbing models that can be used in different construction sites. It has a high speed for its trolley and slewing mechanisms and are easily adjusted without compromising the construction machinery's stability.

With an imported electronic control system, the top slewing crane has a service life that is three times longer than other cranes on the domestic market, and has fewer errors and is easier to maintain.

The tower crane features a lightweight structure in which the mast sections have integral angle steel welding that is safe and reliable. Advanced mechanical or Mechatronics products work efficiently even in poor conditions to keep the tower cranes working safely at top performance.


Advanced Electronic Appliances

1) Excellent safety devices including weight limiters, moment limiters, height limiters, radius limiters, slewing limiters, and slewing and trolleying brakes
2) Device to prevent the wire ropes and shafts from breaking
3) The rope controlling system of hoisting mechanism
