Technical Features
（1）Power system：
The well-chosen chassis from world renowned brand features strong power output and stable performance. The original German STIEBEL transfer case features long service life, high power output, high efficiency, and stable and reliable operations.
（2）Hydraulic system：
The pumping hydraulic system adopts double-pump double-circuit open hydraulic system and adopts the German Rexroth oil pumps. The main cylinder and swing cylinder are driven by two pumps separately. The swing cylinder features quick and powerful motions. The pumping hydraulic system adopts the electronically controlled reversing mode, featuring simple and clear system structure and convenient malfunction repairs. The hydraulically controlled reversing mode is optional.
（3）Pumping system：
The maximum capacity of the hopper is 600L and the inner walls of hopper adopt arc-shaped design to eliminate dead angle for material deposit and minimize the residual material. The S-valves adopt highly wear-resistant wearing plate and cutting ring to ensure long service life and sufficiently reduce the operation cost of the user. The mixing blades of the mixing mechanism feature reasonable design to improve the concrete suction efficiency. The hydraulic motor adopts direct drive mode, featuring simple transmission structure and convenient repair. The mixing mechanism is capable of automatic reversing in event of material blockage and then automatic resumption of forward rotation.
（4）Boom and outriggers：
Through the finite element calculation and modal analysis, simulation of multi-body dynamics, and repeated testing and backed by the precise data, the optimized design in terms of weight, strength, stiffness, and stability is achieved to guarantee the reasonable design and outstanding performance of the structural parts. All structural parts for boom and outriggers are made of WELDOX high strength steel plates from Swedish SSAB, featuring high strength, light weight, and predominant fatigue resistance. The boom adopts the RZ-shaped folding mode, featuring wide placement scope and flexible operations. The boom balance valves adopt RZ products with overload cushion protection function to effectively prevent the possibility of overload failure of hydraulic system and the damage of structure. The outriggers are of the traditional backward-swinging type, featuring quick extension and simple and reliable operations.
（5）Central lubrication system：
The S-shaped valve and concrete delivery cylinder of the pump truck adopt central lubrication mode so that the hydraulically controlled follow-up grease pump guarantees the lubrication effect and features low grease consumption. All lubrication points of the multi-plate progressive grease distributor are fitted with blockage indicator to ease the maintenance and checking. In event of blockage in any oil line, the other oil lines can still function normally.
（6）Efficient cooling system
The efficient electronically controlled cooling system guarantees low temperature rise of hydraulic oil.
（7）Operation and control system：
The operation modes of the pump truck include: 1. Electric panel operation; 2. Wireless remote operation; 3. Manual emergency operation.
