QTZ50(5008)construction towercrane

All of construction tower cranesare incorporated with internationally advanced "Tower Crane ComputerizedDesign Platform(TCDP)" optimized design,featuring in advanced mechanism,uniform load bearing,good appearance,superior performance and complete,reliablesafety devices.

QTZ series tower crane is a kindof upper-slewing fixed type tower crane. It can be used into every kind ofindustrial and civil construction, especially suitable for the constructionsite which is narrow and landform is complicated. 
Tower crane has hoisting, slewing and trolleying mechanisms. They can workrespectively or together to raise working efficiency. Hoisting mechanism adoptsdouble-speed electromotor, it has two kinds of work speed: Lifting and slowlyin position, so as to satisfy different work requirement. Jib can rotate 360°Freely. Level arm frame, trolley range-changing, agile and reliable, lifting inposition is accurate. It can satisfy vertical and level transport demand ofconstruction at a time.
