Abstract

1426338 Staker props GEWERKSCHAFT EISENHUTTE WESTFALIA 10 July 1973 [13 July 1972] 32745/73 Heading E1P An advancable staker support prop 12 for a conveyor comprises a hollow floor member 10 having a beam 23 which is telescopically mounted therein and pivotally connected at 25 to guide means 24 for the conveyor, means such as a double-acting piston-and-cylinder unit 33, 35, 26, 28 being provided for effecting relative movement between the floor member and the beam and for adjusting the inclination of the guide means. The cylinders 26, 33 are pivoted to a fixed lug 27 by a pin 34 and their respective pistons 28, 35 are connected to a fixed cross-piece 30 and the wall 37 of the guide means 34 by ball joints 29, 36. For numerous minor modifications Fig. 2, (not shown), and the Specification should be referred to.
