Crane

Brief introduction of tower crane

The working mechanism of the crane is simply in drive lines, small in size, reliable in operation and convenient in transportation. The Modular tools of the tower crane are made through welding angle iron which is safe and reliable. Every mechanism is compact in structure, advance in technology, complete with all the safety equipments and it is also mechanical or mechatronics products, applicable to bad construction environment which can ensure the tower crane working reliable.

The design of the tower crane is trying to adapt advanced mature technology in domestic and abroad based on the situation of countries and principle of safe and reliability to develop the technology level. The adopted technologies are as follows:

The Electric Assemble applied in our tower crane is manufactured by Professional Electric appliance Factory which introducing the advanced technology from France.
Introducing foreign advanced technology and domestication equipments such as Weight limiter, Moment limiter, Height Limiter, Amplitude Limiter, Slewing Limiter, swing brake, Traction mechanism brake etc safety equipments in the tower crane.
