Abstract

1308600 Vehicle stands J I CASE CO 18 May 1971 [22 July 1970] 15497/71 Heading B7J [Also in Division B8] A mobile crane (see Division B8) (Fig. 1, not shown), comprises a telescopic jib (24) mounted for slewing and luffiing on a base (12) supported on wheels (14). In order to stabilize the crane at a location of operation, outriggers 34, 36, 38, 40 attached to the base (12) are actuated to raise the wheels (14) above the ground. The outriggers 34 to 40 are fluid actuated, each including a single acting cylinder 42 having a piston rod 44 extending therefrom with a ground-engaging rod 46. The piston rods 44 are biased to the retracted position by biasing means 48 and extended by pressure fluid supplied from a reservoir 50 by a pump 52 supplying a control valve 54 with conduits 58 to the outriggers. Each cylinder 42 has a pressure-responsive means 60 preset to be actuated when the pressure drops to a predetermined level. This closes a micro-switch 76 and actuates a warning device 74 indicating that the crane is near a tipping condition.
