Advantages

Divided into two types: stationary and rail-mounted.

Many choices when using, such as adjustable height according to job requirements, tubular or lattice towers, and foundation bases or rails.

Multiple rational combinations foe a variety of requirements and scientific safely protecting structures for higher reliability.

Widely used in construction buildings, such as the construction of precast concrete beams, bridges, nuclear power plants, infra-structures, harbors and ports.

Power& hydraulic system

We adopt the world-famous brands- Yantai motors and Beide motors of Siemens.

We adopt original VOLVO diesel engines as the power of the pumps.

The main oil pumps adopt German HAWE, Rexroth series and Japanese Kawasaki series.

The hydraulic valves apply the world-famous brand. The hydraulic concrete pump apply specially-made hydraulic valves with a large flow and a little energy loss. This insures the reliability of the system and at the same time saves energy.

The hydraulic rubber hose joints are products of American Eaton, insuring the safety and no leakage of hydraulic system.

The radiator is air-cooled type, enabling the machine to work under the allowable highest temperature.

The seal components in big oil cylinder adopt the products of American Parker.

Electric parts

Main electric elements are from Schneider and LG company, the reliability of the electric-control system is highly improved.

Mechanical parts

S tube valves are cast into shape with austenitic manganese steel, the quick wearing surface is welded with wear-resistant material, has the dual advantages of anti-high pressure and anti-wearing. The inner surface of the tube transits smoothly and the concrete can flow freely in the tube, improving the pumping performance further. The spilled shaft is made of alloy and the surface is specially treated, its abrasion performance and fatigue strength is enhanced.

Glasses plates and cut loops are made of anti-wearing horniness alloy, they have long service lives.

The mixing system has special double sealing structure, filled with high pressure lubricating oil, which can prevent the material entering the system and protect the mixing shaft feeding with highly wear-resistant and large-angle paddles efficiently boosts the absorption performance.

The concrete piston are precisely processed with imported material, having hydrolytic resistant, wear resistant and high temperature resistant characteristics.

Lubrication system

Centralized lubrication system adopts progressive distributor which supplies every lubrication point with oil in turn, and the oiling time can be set. So the oiling is accurate and the oil consumption can be saved.

Characteristics

Overall hydraulic commutation system: the alternative commutation actions between pumping and S tube distribution doesn’t involve electric signals. Little impact and noise occurs during the commutation, so the service live of the hydraulic pump and valves are evidently lengthened.

Overall hydraulic system saves the intermediate process of the electric signals. In this way, the reliability of the whole equipment is greatly increased.

Centralized valve plate: the hydraulic valves of main system are centralized in one valve plate. The number of cross-connected pipelines is reduced, the system gets more compact, at the oil leaking possibility is decreased.
