Product Description

Cab: The appearance is beautifully designed, the internal capacious and bright, pantoscopic and bult-in monolithic linkage work station. Nice shape and compact structure. All used ABB or Schneider contactors, make the work safe and reliable. This can provide more comfortable working environment for the drivers.

Electroplax: The power distribution system platoon walk line is reasonable,elegant appearance,simple and useful,easy to maintenance which produced by our conpany. Adopted the international famous brand ABB electric,which makes the quality performance more stable and reliable.

Organization: Hoisting mechanism is mainly adopted international famous brand jiangte organizations. The structure have some advantange, such as: compact structure, drive stable, big traction pull, low noise, easy installation,etc. The tower cranes work more smoothly and efficient. Because of the good quality and low maintenance rate, we have a very good reputation in the broad masses of customers.
Slewing mechanism: Mainly used the domestic famous brands Texas built institutions. This institutions structure is very reasonable,drive stable,low noise,make the tower crane smooth the same ring. The good quality and low maintenance are popular with the manufacturers and customers.
Trolleying: Our company adopted the horizontal planetary luffing structure form which popular and practical now in the dometic. The structure have some advantange , such as :compact structure,drive stable,low noise,etc.  This makes the tower crane more smooth and safe in operation,provide the convenience for users in the use and maintenance.
