High Quality Shantui 56m Boom Pump Truck

Technical Features
(1)Strong and reliable power system:
*The well-chosen three-axle chassis of world's renowned brand abundantly plays the potentials of three-axle chassis to save the cost for you and improve the competitive edge of the product.
*The original German STIEBEL transfer case features long service life, high power output, high efficiency, and stable and reliable operations.
(2)Stable hydraulic system:
*The double-pump double-circuit open hydraulic system adopts the German Rexroth products.
* The swing cylinder features rapid and powerful motions, fast reversing, and low impact.
* The hydraulically controlled reversing system features simple and clear structure and easy troubleshooting.
* The unique design of independent oil tank and water tank eases the cleaning and maintenances.
* The prominent filtration system keeps the hydraulic oil clean without contamination.
(3)High-efficiency pumping system:
*The maximum capacity of the hopper is 600L and the inner walls of hopper adopt arc-shaped design to eliminate dead spaces for material deposit and achieve high suction performance..
*The S-valve adopts highly wear-resistant wearing plate and cutting ring, featuring long service life and low maintenance cost.
*The hydraulic motor driven mixing system features simple drive structure and easy maintenances.
*The design optimized vanes improve the material suction performance and are capable of automatic reversing in event of blockage and then automatic resumption of forward rotation.
(4)Lightweight boom and outriggers:
*The WELDOX high strength steel plates from Swedish SSAB are completely applied, featuring high strength, light weight, and pdominant fatigue resistance.
*The five-section boom adopts the RZ-shaped folding mode, featuring high placement scope and flexible operations.
*German HAWE balance valves feature overload cushion protection function to improve the product reliability.
*The X-shaped outriggers feature high space utilization rate and more reasonable frame design.
(5)Low-consumption and high-efficiency lubrication system:
*With the application of central lubrication mode, the hydraulically controlled follow-up grease pump guarantees the outstanding lubrication effect and features low consumption and high efficiency.
* Multi-plate progressive grease distributor is adopted and all lubrication points are fitted with blockage indicator. The blockage of individual oil line will not impair the normal operations.
(6)Efficient cooling system
* The efficient electronically controlled cooling system guarantees low temperature rise of hydraulic oil.
(7)Humanized operation and control system:
*Three operation modes, namely electric panel operation, wireless remote operation, and manual emergency operation, are provided to ease your operations.
