1 Hoisting Mechanism
Three-gear speed modulation by electrical motor or frequency conversion, giant winch.
2 Rotation Mechanism
Speed modulation with frequency conversion, stable break, accurate position, outstanding on performance and operation all around the world.
3 Luffing Mechanism
Speed modulation with frequency conversion, less concussion, stable operation.
4 Control System
PLC control, auto diagnosis on electric malfunction, corresponding alarm on light and sound, key components adopting international top brand product.
5 Security & Protection Mechanism
Besides security mechanism usually used in domestic tower crane adopted, Zoomlion tower crane adopted lots of advanced mechanism self-developed by Zoomlion, to keep the security of the tower crane and convenient operation, such as unique double tighten mechanism on luffing steel cable, anti-break mechanism on sliding vehicle, anti-drop mechanism on standard section, speedy link between rotary body, hoisting boom and balance boom.
6 Structure
Through advenced design, mechanical-electrical integration design, CAD supporting design, optimization design, modularization design, makes Zoomlion tower crane's steel structure haveing outstanding intensity, firmness and anti-fatigue capability, outstanding performance and reliability. With beautiful profile, it embodies the design standard of Zoomlion.

 

International Top Brand Electrical Components
Electricla components are global top brand.
 
 PCL control
Intelligent control, more accurate, more cooperative, more convenient maintanence, and more reliable.
 
 Hoisting Mechanism
Frequency conversion speed modulation, multipolar winding machine series resistance speed modulation, and polar conversion speed modulation for hoisting mechanism. Frequence conversion modulate speed smoothly, and reliable; multipolar winding machine series resistance has less concussion electricity in speedy hoisting, breaking, and gear shifting, reliable operation; polar conversion speed modulation mechanism is simple, economical and practical.
 
 Luffing Mechanism
 Luffing mechanism has two speed modulation way. Frequency conversion speed modulation is stable and no concussion, polar conversion speed modulation is practical and economical.
 
 Rotary Mechanism
Rotary Mechanism speed modulated by frequencey conversion and winding machine series resistance.
 
 Data Supervising System
Adopting data supervising system, tells you whatever you want to know.
 Hook auto modulate ratio
Hook auto modulate ratio, convenient, speedy, embodied low speed for heavy load and high speed for light load, more efficiently.
