Abstract

1,157,486. Shovelling machines. WARNER & SWASEY CO. 25 Nov., 1966 [4 April, 1966], No. 52801/66. Heading E1F. In a material-handling machine, e.g. a back hoe shovel excavator, a dipper stick - carrying boom can be swung vertically either at a high speed through a relatively large angular displacement by a low torque or at a slow speed through a smaller angular displacement by a greater torque by a hydraulic ram according to the powered positioning of the positioning of the pivot axis 32 of the ram 15 on the boom-supporting structure 12 of the machine. The ram cylinder 28 is pivotally connected at 32 to a block 35 pivotable by a ram 30 about an axis 36 on the structure 12. Specifications 1157487 and 1157488 are referred to.
