1. ) Material
The steel of crane is from Chinese famous steel companies.
2. )Electrical mechanism
Elements for electrical system are Siemens or Schneider.
Electronic control adopts the advanced frequency conversion control technology, RCV/PLC stepless frequency speed electronic control system.
3. )Hoist mechanism
Brake wheel adopts cast steel materials, surface quenching and external circular, control the beating degree strictly. At the same time, also carrying on balance tests. Each hoisting mechanism is carrying on no-load, static load, dynamic load and so on, guarantee the reliability, safety and durableness.
4. )Trolley mechanism
Trolley mechanism with free maintenance planetary reducer and cone brake motor, is well-knit in structure, stable and powerful in trolley, high endurance and low failure rate.
5. )Slewing mechanism
Slewing motor adopts winding motor and hydraulic transmission.
6. )Operation device
Cabin with humanized design, is convenient and comfortable, facilitate for safe driving. It creates a good working environment for the operator.
7. )Safety devices
The crane has a complete set of safety devices: Crane high limiter, weight limiter, moment limiter, circumgyrating limiter, etc.2. Description of QTZ series tower Crane1) 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.3. Service
1. ) Providing timely delivery, standby engineers are ready to solve any problems
2. ) Providing 12 (twelve only)months product warranty period, with ample spare parts
3. ) Providing work site installation guidance and training of operation and maintenances ModelsFree height(m)Max. height(m)Jib length(m)Max.
