The boom driven by a single cylinder and the synchronously amplitude-varying and lifted stand column enhance the operating speed, and realize the fast access to the construction area, which will improve the construction efficiency.

2、Better Adaptability to Poor Construction Enviroment

The application of a lubrication-free shaft sleeve and slider relieves the friction between each hinge point for connection and inter-arm slider, thus resulting in better adaptability to welding and dusty enviromeent.

3.Advanced power system integration control

Electronic-controlled engine is adopted as the dynamical system, oil pressure, water temperature, rotating speed, sensor etc. are integrated by engine and controlled through ECU, which is safe and reliable. Meanwhile, there is a fault diagnosis interface as supporting for convenient of fault diagnosis and maintenance.
