It is highly reliable and durable with seven technical highlights. More advanced boom structure technology ,More efficient rock valve pumping technology, Steadier stabilizer structure technology, Steadier reversing buffering technology, more reliable fully-hydraulic reversing technology, Ultra-low pressure loss hydraulic system technology, safer and smarter electrical control system.
Smooth pumping and low blockage rate ensured by optimized pumping mechanism, which is created by years of experience. The whole pumping system can reduce concrete stratification time and slow down the rate of concrete separation during pumping.
With a 6-section RZ boom structure, the boom has a short folding and unfolding time, and the end hose can be moved quickly to the point where the concrete is needed. The last two boom section is short, ensuring that the boom able to passes through a tight space.
Rotary anti-swing control technology
With the new rotary brake technology, the boom swing amplitude is reduced by 60%.
High abrasion wear parts
The full integration of Germany’s technology has greatly improved performance. Straight pipe, hinged elbow pipe, large elbow pipe, and small elbow can reach a service life of 20-30 thousand cubes; the discharge port and transition sleeve can reach 40 to 60 thousand cubes; the life span of a piston can reach 20 thousand cubes; The service life reaches 50 thousand cubes, the cutting ring has a service life of 20 thousand cubes, and the delivery cylinder has a service life of 100 to 140 thousand cubes.
Fault self-diagnosis technology
The device status can be inspected every moment to monitor and diagnose faults in real time, which can effectively shorten the time for troubleshooting by 70%, saving you time and effort.
Intelligent arm system
Lift arm: Push the arm up/down switch up or down to automatically open or retract the boom.
Limited activity height: When working with obstacles places can effectively prevent the damage caused.
Boom overload protection technology:
A safety valve device is added to the boom cylinder balance valve. When the boom load is too large, the overload oil pressure is automatically released to protect the boom from damage.
Hydraulic oil level automatic detection and protection technology:
real-time monitoring of hydraulic oil reserves, automatic alarm or stop pumping when the amount of oil is insufficient to ensure that the hydraulic system is not damaged.
