Product Overview
The system consists of a controller, solenoid valve drivers, an electro-hydraulic directional valve group, and a remote control transmitter. The system is compact in structure and easy to install. It is powered by a storage battery, allowing flexible deployment and installation in passive environments. The system adopts remote control operation, which facilitates on-site personnel operation, greatly reduces the labor intensity of on-site workers, and improves work efficiency.
Product Functions
Wide Applicable Scenarios
It can be widely used for the control of hydraulic supports in mining faces and gob-side entry retaining hydraulic support withdrawal, as well as advance support and temporary support in roadways and other passive scenarios.
Wireless Control
The remote control can perform remote operation of the system within the line of sight.
Continuous Operation
It can work continuously for ≥8h (withdrawal scenarios), with a standby time of ≥12h. It enters a low-power standby state when there is no action.
Flexible Assembly
The controller adopts a magnetic attachment design, allowing flexible installation and convenient use and maintenance.

Typical Applications
The electro-hydraulic control system for hydraulic support withdrawal can be widely used in coal mine mining faces and gob-side entry retaining hydraulic support withdrawal control. Due to the particularity of the withdrawal environment of hydraulic supports in mining faces and gob-side entry retaining, the operation of withdrawing supports is very difficult. In addition, support operation is difficult in scenarios such as advance support and temporary support in roadways. The electro-hydraulic control system for hydraulic support withdrawal developed for the above scenarios adopts a built-in storage battery for power supply, allowing the system to operate normally in passive scenarios. At the same time, the system adopts remote control operation, reducing the number of equipment and improving system stability. In addition, the equipment of the electro-hydraulic control system for support withdrawal is compact, allowing convenient on-site flexible installation and configuration.
