Hydraulic self-advancing support assembly in combination with a winning apparatus circulating at the roof and floor

摘要

The hydraulic self-advancing support assembly essentially consists of a floor skid 1, a prop 2 and a roof bar 3. Linked to the roof bar 3 on the waste side is an inclined gob shield 5 which on the floor side is supported with a shield link 7 on a base frame 9. The base frame 9 encloses the floor skid 1 all round and on the face side forms the support for a winning wall 11 which can be vertically adjusted in adaptation to the seam thickness and on which the winning apparatus is guided. A clamping cylinder 18 supported on the floor skid 1 is attached to the winning wall 11. An expanding cylinder 17 is linked in the gusset between gob shield 5 and shield link 7 at a distance from the joint 6.
