The performance of QTZ63 Hydraulic self-lifting Tower Crane is good, and it has following functions: it can be independently installed or attached installed to a building, hydraulic climbing heightened, horizontal boom support, equipped with luffing carriage, self-lifting upper platform. It has standard boom length of 45m, and 50m with an extended boom; Max. Lifting weight 6t; Rated-lifting moment is 630KN.m.
Following is the main characteristics:
1.2 High working speed, good speed adjusting performance, stable operation and high working efficiency. The lifting mechanism adopts tri-speed motor and single reduction ratio reducer, and could realize functions of low speed with heavy load and high speed with light load, it max speed could reach to 65.5m/min. The luffing carriage could move along the horizontal boom to realize the radius changing, and it is easy to be installed. Slewing mechanism adopts planetary gear reducer, equipped with moment limiting type coupling, and it has functions of high lifting capacity, stable startup, reliable working condition, and working normal in wind, etc.
