Performance characteristics:

1.Automatic piston retraction, convenient to maintain

2.New generation electronic control system adopts energy-saving technology, which is easy to operate, safe and reliable.

3.Self-diagnosis system, CAN bus, dedicated controller application, allowing operators to monitor system status real time. Improving electrical system reliability

4.The boom movement flow is self-distributed, and the control system automatically adjusts the proportional current of the multi-way valve to ensure the continuity and coordination of the boom movement.


The 4-section “M” –folding placing boom is designed with such advanced design methods as finite element analysis and variable cross-section of equal strength parametric design and dynamic simulation, which optimizes structural design parameters; with lighter weight, better stability and smaller unfolding space, it is especially suitable for tunnel and interior operation whose building sites are confined.

The front “X” stabilizers single side working can make real-time detection of the positions of stabilizers on both sides and control the efficient slewing range of boom and can work normally in narrower space which doesn’t allow the stabilizers to be fully extended.

New breakthrough in remote monitoring technology

The remote monitoring system uses such technologies as computer network, radio-communication, special location and advanced geographical information to monitor the working condition of overall vehicle to realize remote diagnosis and prewarning of faults, which provides powerful technological support for marketing and after-sales service.  

Full-automatic high/low pressure automatic switchover

It means when operating high/low pressure switchover, instead of switching pipelines or turning valve plates, the user just press one button and all operation can be completed. It is easy to use and can quickly remove pipe blockage, leaving no leakage.

Piston automatic return

The concrete piston can automatically return to water groove by just pressing a button, which is convenient for replacing concrete piston and checking the wear of concrete piston at any time. It features easy operation, convenience, time and labor saving, and high security.

Flexible suspension pumping system

The connection between hopper and sub-frame adopts pivoted axle and adds flexible damping device, which absorbs the vibration produced when the core pumping system works, reduces the influence of pumping system on the vibration of superstructure and boom and thus largely extends the service life of structural parts and hydraulic parts.
