, QTZ260 (TC7016)

The TC7016 hammerhead tower crane has advanced technical parameters with a maximum radius of 70m and a maximum height of 183m with mast sections and anchorages.

The hammerhead tower crane has a high speed for its trolley and slewing mechanisms and are easily adjusted without compromising the construction crane's stability. The hoisting mechanism uses a frequency motor and can reach a maximum speed of 80m/min.

With an imported electronic control system, the top slewing crane has a service life that is three times longer than other tower 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) 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
