General Introduction

 

 

 

DT20 movable arm self-climbing tower crane is one of our new model of frequency control of motor speed of tower crane.    

 

 

 

The tower crane has the following characteristics:    

 

 

 

1, the tower crane is designed for small high-rise building construction, layout reasonable, beautiful appearance, small requirement for installation and rotary space, more convenient for small high-rise building construction requirements.      

 

 

 

2, compared with general tower crane has the advantages of simple structure, easy installation, good speed control performance, electrical automation with higher characteristic;

 

Hoisting mechanism, slewing mechanism, luffing mechanism adopts frequency control of motor speed, stable and reliable working, high efficiency.  

 

 

 

3, all kinds of security devices are complete, can guarantee work safe and efficient. This machine is equipped with the moment limiter, lifting weight limiter, rotary limiter device etc safety device;    

 

 

 

4, tower crane by increasing or decreasing some parts and auxiliary equipment, can be used for independent and internal climbing two working conditions.  

 

Under the condition of internal climbing, the tower crane can be raised with the building rises, using hydraulic jack-up, does not need increase the standard section.      

 

5, the maximum moment is 12 T.M, and arm length is 12 M, with a total of 4 sections.

 

 

 

By luffing winch and luffing pulleys to drive the forearm luffing. The arm luffing Angle is 15 ° ~ 75 °, upward arm within 75 ° ~ 60 ° arm Angle can be maximum loading for 2 t, lifting range of 12 meters, the capacity is 1 t.  

 

 

 

When hoisting exceed the permitted maximum lifting or lifting moment, electronic control system will automatically disconnect, implements the protection, improves the safety performance.
