The integrated maintenance and support center provides testing of hydraulic components, hydraulic cylinders and pump motors, as well as oil detection and purification. Based on the different environmental cleanliness requirements of the various functions, the maintenance and support center is divided into two parts: the clean test area and the standard test area. The hydraulic part test area is located in the clean test area, while the pipeline manufacturing and hydraulic pre-treatment area is in the standard test area. A modular design is used for the test beds in each part of the test area.
