01

Double open hydraulic loops (pumping hydraulic circuit is independent of distributing hydraulic circuit) with two pumps, makes the whole hydraulic system much simpler. The reliability of the whole system is also much higher as well as the components’ life is prolonged greatly. This is convenient for judging and removing trouble.

02

Large valve changing direction, makes the main pumping loop quick response, small leakage, good stability, high reliability and high resist contaminative capability.

03

Hydraulic system has safe relief protection, at the same time, when the system pressure is over, the main oil pump cutting device makes itself be protected reliably.

04

Distributing hydraulic circuit adopts constant pressure pump, which can provide strong distributing pressure and economic energy control.

05

Cone sealing of all pipes make the pipe joints seal reliably.

06

The high-low pressure switch adopting cartridge valve of reduces the trouble of dismantling and installing the oil pipe.

07

Adopt emulsification technology of initiative and passivity recovery integration.

08

Compared with domestic product, the electric control system is simplest, the element quantity is fewest and its reliability is highest.

09

The wire remote equipment is convenient for operation from a far away distance.

10

Adopting proximity switch in hydraulic cylinder can realize changing direction with non-touch, which ensures that the direction can be changed reliably.

11

The design of hopper and S valve and so on adopt I-DEAS software to calculate, the hopper and S valve have good rigidity to avoid the phenomenon of hopper distortion and S valve breakage.

12

The agitator has unique form, which separates the hydraulic motor from agitator bearing pedestal. At the same time, adopting large displacement motor ensures that the agitator moment is big enough.

13

To make sure the pumping is good and avoid the phenomenon of pipe jam, the spectacles wear plate and cutting ring should be used in lower abrasion. FOCUS's spectacles wear plate and cutting ring use high wear material, making the components’ life prolonged greatly.

14

The hydraulic circuit will take high oil into double distributor, and then the lubricating part can obtain hydraulic oil. It ensures the lubrication of the concrete cylinder’s piston and other parts and prolongs the life of piston and other sealing knits.

15

The radiator equipment makes the working oil temperature of hydraulic system below 70℃ and makes the machine in normal status.
