Manufacturer of fixed self-climbing 6t Topkit Tower Crane QTZ63

  Product   China shandong baimai construction machinery co., LTD.                              Welcome new and old friends come to visit our factory Product Description 1) QTZ63 tower crane is one of the key product of BAIMAI company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.   2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected; The max. attached height can reach 140m.   3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.     4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.   5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.       Packaging & Shipping contact    Factory production of tower crane , can give you a satisfactory ex-factory price, quality assurance, welcome to visit  This product shipping need four  40' HQ   Inland transport need to use a flat car   Technical performance of crane  Hoisting performance table 60 meters working range
