Highly Reliable Hydraulic System

· Duplex pump. The large displacement pump is used for the height adjustment system and the small displacement pump is used for the brake system to reduce the system power loss.

· The oil return pipeline is installed with a fin-type cooler to guarantee that the oil temperature is below 50℃.

High-Reliability Electric System

· The harness design within the electric cabinet realizes the stratified layout for cables and fluid pipes within the machine body.

· The high integrated and modularized design is taken for the main control cabinet and inspection cabinet to ensure integral replacement and easy maintenance.

· Shock test and inspection for electric components.

System Level Based Gear Micro-Modification Technology

· The gears are micro-modified based on the housing

· deformation condition to prevent the partial offset load of the tooth face.

High Machining Accuracy of Housing

· The housing is finish machined by an imported machining center to guarantee perfect dimensional tolerances and roughness for the housing and thus ensure the good functioning of the whole drive system.

· The imported constant-temperature coordinates inspection center is used to inspect the housing and guarantee 100% tolerance conformance.
