Description of QTZ series tower Crane
 
1) the tower crane is one of the most popular type and hot-selling self-erecting tower crane, which is researched and designed by Institute of Building Mechanization of China Academy of Building Research. It absorbs many advanced technology both from China mainland and abroad.
2) We adopt to use Dual drawbars structure on lifting boom, which enables the lifting boom to be unfer no stress at lifting surface other than uniaxial stress, and moreover, it gets rid of the stress peak. It greatly improves the fatigue safety performance of lifting boom.
3) Adopts VVVF stepless speed variation device for lifting, radius changing and slewing mechanisms, to make sure it works steadily and effectively, it also lowers the maintenance cost.
4)We can offer crane standard sections such as the FO/23B standard sections for customers to choose from.

Description of QTZ series tower Crane
 

1. QTZ series tower crane adopts standard section hydraulic lifting and connecting.
2. The max. height of crane can reach 180m -200m with wall tie ins.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 construction, which enables heavy load low speed and light load high speed.
   The range-change structure drives the trolley cart moving on the horizontal lifting jib, with good positioning performance. Planet gear decelerator is applied in the circumventing structure, together with moment-limiting hydraulic coupler, which can realize high load capacity, steady starting and reliable operation.
   4) The crane has complete set of safety devices, which can guarantee the safe and high efficient operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..
   5)The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.
