HydraulicSystem of the Trailer Concrete Pump
Both the main pumping circuit and "S" valvecircuit are open-circuit. They are separately driven by a pump, which makes thetwo circuits independent to each other. The simplified system, results in alonger service life, higher reliability and easier troubleshooting.
Proximity switch used to control the direction of the main pumping makeschangeover steady and reliable.
Main components of the hydraulic system are famous brand products. The use ofspecial safety devices, such as relief valve, pressure cut-off control,alarming system and auto-reversing device, promises the system will be morereliable than ever.
Driven by the constant pressure pump with an accumulator, the swivel cylindercan get enough moment and save power at the same time.
All imported seal kits ensure higher reliabilityand a longer lifetime.
Due to the electrical solenoid or hydraulic directional valve, the switchingfrom high pressure to low pressure becomes easy and quick. There is lesshydraulic leakage than the similar domestic products.

Electrical System of the TrailerConcrete Pump
It features advanced performance, effortlessoperation and high reliability.
The electrical system comes with a Programmable Logic Controller (PLC), whichtakes the place of many relays such as time relays. This not only greatlyreduces the use of components but also simplifies wiring in the system,resulting in a higher reliability. In combination with PLC, a visual displaycan indicate the status of inputs and outputs, leading to an easiertroubleshooting. 90% of the electrical components are gathered from worldrenowned brands, so their reliability is guaranteed. The utilization of aremote controller enables the user to conveniently operate the system from along distance. In addition, the proximity switches can help to realizeautomatic direction changeover.

Mechanical System of the TrailerConcrete Pump
In designing key parts, such as "S" pipe distribution valve andhopper, software I-DEAS is adopted to realize Finite Element analysis of loaddistribution, construction rigidity and stress concentration. As a result, theoptimized hopper and "S" valve system effectively avoid the followingphenomena like hopper distortion and breakage of "S" pipe valveshaft during high pressure conveying.
By a specially designed sealing structure of agitator,hydraulic motors are completely separated from bearing seats, so even under thesituation of sealing failure, the slurry has no chanceof getting into motor. High-torque motors ensure high mixing torque. Thanks tothe auto-reversing device and anti-wearing blades, the blockade will neverhappen even under severe conditions.
The wearing parts, such as the anti-wearing plate and the cutting ring, have along service life up to 20000m3under favorable condition.
The distance between the anti-wearing plate and thecutting ring can be automatically adjusted.

Driven System
Deutz diesel engine, equipped with electronicaccelerator device.

Lubrication System
The patented central automatic lubrication system comes with a pistongrease-pump, which features high pressure and reliability and can realizeautomatic lubrication of piston. The filters at the outlet and the inlet of oilports provide double protection, thus guaranteeing the system reliability.
