, QTZ100 (TC5516/6010/6013)

The QTZ100 hammerhead tower crane is a newly designed self-erecting top slewing tower crane. The maximum radius is 55/60m and the maximum height reaches 150m by adding mast sections and anchorages.

With various models such as stationary, external climbing and inner climbing slewing cranes, this balance crane is widely used at 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 hammerhead 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) Equipped with excellent safety devices, produced by leading technology, 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
