The concrete pumps are our corporation proper motion develop successfully concrete pump, they possess hereinafter main feature.

1. Hydraulics is electric-hydraulic control commutation and the system is simple low failure rate.

2. Control circuit adopt Omron corporation's programmable logic controller, it simplifies circuit and increases system reliability.

3. of the circuit high pressure small quantity and low pressure large quantity amphi-mean of delivery

4. with the function of crawl advance and crawl fallback.

Main cylinder automatism topping-up oil and charged with plug-in mounting type non-return valve both end. When the plunger moves approach to the stroke end pressure oil open non-return valve and topping-up of oil to the closing oil circuit.

Hydraulics adopt the component element from Rexroth electric-hydraulic control, both easy and simple to handle, smooth performance shake and noise all are on the small side possess perfect electricity-hydraulic overload protection and meter display system.

Advanced integration electric control unit; Control circuit adopts the programmable controller from Omron Corporation. The rest electric application component element partly adopt import component element. Large logical control was finished by programmable controller. It simplifies circuit and increase the performance and reliability of the electric system.
