МЭГ.00.000-01 electrohydraulic control assembly

Application of electrohydraulic control systems is a perspective advancement in mining industry development.

"МЭГ.00.000-01"High performance and labor safety in mining industry can be attained not only by improvements in coal mining technology and production technique, but also through reduction of labor-intensive and dangerous operations inside mining and development faces based on production processes automation. Electrohydraulic control assemblies «МЭГ» clearly serve this purpose.

Electrohydraulic control assembly МЭГ is intended for control over hydraulic power components of powered mine roof support. Implementing this type of control assemblies within mining face should allow achieving a significant increase in mining and extraction, labor safety and performance in longwall faces.

The assembly provides a possibility to control from 1 to 10 hydraulic cylinders.
