Printed Gaskets in Hydraulic Control Equipment

Printed Gaskets in Hydraulic Control Equipment Dowty Seals Limited 

This equipment was developed for use in roof support systems in coal mines (although it is expected to find numerous applications in other industries). 

The roof support shields are used to control the overlying strata, at the coal face, and thus protect the operators of the coal-cutting and conveying equipment. During mining operations the shield canopy is raised hydraulically against the mine roof later it can be lowered and the shield moved laterally with a hydraulic ram thus the shield is self-advancing.
