QTZ80 Tower Crane

11 years golden suppier in China, exported to more than 50 countries. 25 years history.
1.1 The tower could be heightened with hydraulic climbing standard sections, and the tower height could be adjusted according to the actual building height, and the tower crane lifting capability wont be affected even it is heightened.
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. 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.
1.3Wide working range and wide application.
Through changing and adjusting some parts or associated devices, the tower crane could be installed independently from or attached to a building, to meet different requirements. The max lifting height could reach to 120m under attached installation method (multiply factor 2), and 29m to be supply height under stationary type.
