QTZ63 50m CE Hammer Head Tower Crane

QTZ63 Hammerhead Tower Crane is a multifunctional tower crane which is of horizontal jib, trolley mechanism and stationary jack-up type. QTZ63 top-kit tower crane`s max. Lifting capacity is 8 tons, independent hoisting height is 45m, maximum height can reach 180m in anchorage state. QTZ63 works fast and stable, the adjusting ability is excellent. The hoisting mechanism adopts three-speed motor, which can offer multiple speeds by changing the fall, and realize low-speed heavy loading, high-speed heavy loading and high reliability. The slewing mechanism adopts wound-type electromotor, planetary reducer and is equipped with hydraulic couplers, can obtain the slewing speed of 0-0.7r/min, which of high loading capacity, stable starting and braking. The operating room is side-seated type, all sides and the bottom are equipped with glass window, which can enable the operator see the loading condition of the minimum range. QTZ63 tower crane is widely applied to high-rise restaurant, residence and industrial building, big-span factory, high-tower building, port, wharf and cargo carrying and handling of cargo yards and so on.
