Support cap for longwall-face support assemblies

摘要

The invention relates to a support cap (1) for the support of a longwall face underground, having at least one sliding cap (5) which is guided on said longwall face and can be moved by an allocated lifting cylinder (3). So that the roof at a longwall face supported with support assemblies can be supported over an area as soon as possible and as close to the coal face as possible after the coal is loosened, the sliding cap (5) is to be a drawer-like box which is open towards the top of the support cap and in which at least one pneumatically or hydraulically inflatable cushion (17) is arranged.
