Electro-hydraulic integration system is matching product of compressed garbage truck and also the key part of it. It consists of three parts, hydraulic station, electric control cabinet and installation frame.
The first two is installed on the frame which is a movable guide rail that allows pushing and pulling. The system can be moved to an ideal position to be installed, repaired and maintained through windows on both sides. Like the way of a drawer, it is very easy to operate.
Electrical relay, alarm, PLC, control panel, etc. are all installed in the electric cabinet for control, display and alarm, simplifying the wire connection. Data collected can be read, written and saved, realizing digitalized control, allowing users to look through complete working procedures of the system without opening the cabinet. There are three ways of control, cabinet control, cable control and wireless control.
Introduction of hydraulic station & installation frame’s code
1 YTJ XX-XX-XX
YTJ——Electro-hydraulic integration system
XX——Motor power: 5.5KW /7.5KW
XX——D High standard configuration G Average standard configuration D
XX——Length：2052 /1997 /1900
Note: Types with length of 2052 and 1997 have air cooling, while the type with length of 1900 doesn’t.

3、Length of the hydraulic station (2052, 1997, 1900) is the width of the garbage compression box.
1. The wire between the cabinet and aviation plug of the compression box’s service entrance is 7 meter long. The wire between the plug to the power supply cabinet is 13 meter long.
2. Length of wire used in cable control: 20m
3. Length of wire used in cabinet control: 10m
|Configuration 1 |
|Motor power ||7.5KW |
