Hydraulic control system replaces the easily damaged four big parts in the electric control and reversing concrete pump, such as PLC, constant pressure pump, accumulator, the proximity switch and so on.
Pump and S pipe distribution for reversing motion alternately doesn’t need electrical signals, which diminish the reversing impact, prolong the service life of the components, reduce the failure rate, greatly improve the overall reliability of the machine, reduce the late maintenance cost and ensure the machine can work safely under harsh conditions.
The main oil pump uses Germany Hawe/ Rexroth/Japanese Kawasaki series. Main electrical components adopt Schneider, hydraulic hose connectors use American Eaton, big oil cylinder sealing elements uses American Parker to ensure product quality.

Trailer-Type Concrete Pump Features
Wear-resisting Concrete Piston Concrete piston made of high toughness and high wear-resistant material adopts the latest design to improve its lubricating effect and increase its service life more than 2 times than conventional concrete piston.
S tube made of manganese steel tube surfacing wear-resisting material and swing axle made of high strength alloy steel can effectively avoid the abrasion of S tube and fracture of shaft head.
Wear-resistant Hard Alloy Glasses Plate and Cutting Ring the service life of glass plate and cutting ring made of the wearable and high-strength alloy material same as hard alloy cutter is extended more than 3 times than those made of surfacing material.
Mixed support structure of unique spherical roller bearing and contacting parts with hard chrome plated wear-proof casing makes the service life of the mixing part improved more than five times.
Streamlined hopper structure are more reasonable, no remaining material blind angle, better material absorbing and easier cleaning.
Multiple Protection Technology Electrical system is equipped with the phase sequence protection, low voltage start, electrical system fault display, multiple protection measures to reduces the damage to the equipment operation.
