Abstract

1346662 Vehicle stabilizers RICHIER 12 Oct 1971 [12 Oct 1970] 47507/71 Heading B7J [Also in Divisions E1-E2] A mobile load-handling machine has two pairs of stabilizing pivotable legs arranged one pair 10, 11 (11 not shown) at the front and one pair 12, 13 at the rear, at least one of these pairs (e.g. 12, 13 as shown) being mounted on acrossbeam 4 pivotally attached about an axis 5 perpendicular thereto and parallel to the longitudinal vertical median plane of the chassis 1 of the machine, to the chassis 1, and the crossbeam 4 is able to be immobilized about the axis 5 relative to the chassis by means, such as two single-acting hydraulic or pneumatic jacks 18, 19, which can also pivot the cross-beam 4 about the axis 5 if either leg 12 or 13 ceases to bear upon the ground during operation so as to cause that leg 12 or 13 to resume bearing upon the ground. The chambers of the jacks 18 and 19, which are connected between the chassis 1 and cross-beam 4 on either side of the axis 5, can be put into communication to cause pivoting of beam 4 when a difference in pressure exists between the two chambers due to loss of ground contact by a leg 12 or 13. The stabilizing legs 10, 11, 12 and 13 are raised and lowered by double-acting hydraulic jacks 14, 15, 16 and 17 (15 not shown). The chambers of a pair of these jacks, e.g. 16 and 17 associated with one pair of legs 12 and 13 may be put into communication so that when a leg 12 or 13 loses ground contact, the pressure difference between these chambers causes lowering of the leg to re-establish contact. A suitable hydraulic/pneumatic control system is described with reference to Fig. 2 (not shown). One pair of legs 10 and 11 may be mounted on a cross-beam 3 fixed rigidly to the chassis 1.
