摘要 |
<p>The support frame is esp. used in mineral-extracting operations in inclined deposits, with bulk backfilling. At least one hydraulic prop is hinged between the floor skid and roof prop. Its lemniscate gear is independent of a backfilling screen at the rear end of the roof cap.S The backfilling screen (8) is approx. upright. There is at least one hydraulic cap-setting cylinder (22) between the lemniscate gear (13) and roof cap (5). This cylinder's flexible connecting joint (24) is located between the prop support point (4) of the roof cap and its backfilling-side end.</p> |
