Control equipment
Based on the accumulated experience and continuous improvements, highly efficient control equipment has been created, which has a high degree of safety and reliability with a long service life:
- pilot control units;
- pilot-type control units with multi-hose;
- control units of manual type;
- limit pressure valves;
- check and controlled check valves;
- electrohydraulic control unit;
- irrigation system.
The electro-hydraulic control system was developed jointly with Marco (Germany). On the basis of cartridge-and-block technology with a large throughput, it provides a high speed of movement of the support with full or partial automation of the process, a slight loss of pressure and ease of operation and maintenance:
- Remote Control;
- hydraulic block;
- hydraulically operated check valves;
- safety and check valves;
- sensors for pressure, inclination, vibration, advance measurement, etc.;
- filters;
- system of cable connectors and hydraulic hoses;
- network power supply;
- explosion-proof РС.
All hydraulic control equipment is tested in a specialized laboratory, the conditions of which are as close as possible to operational ones.
