Abstract
A stabilizing arrangement (1) to support an object above four ground engaging means (2c,3c,4c,5c) has first 2, second 3, third 4 and fourth 5 levers each having a beam portion (2a,3a,4a,5a), an actuating portion (2b,3b,4b,5b) and a ground engaging means (2c,3c,4c,5c). Each lever is connected to a common interconnection means (6) by a respective pivot with a pivot axis. The levers engage consecutively first to second, second to third, third to fourth and fourth to first, via respective projections (2d,3d,4d,5d) permitting ground engaging means warp displacement and thereby the arrangement provides support of the object on uneven ground. For each lever part, the distance a between the respective ground engaging means and the respective pivot axis is a primary lever-rotating moment arm, and the distance b between the respective ground engaging means and the centre of the pivot is a friction loading distance. The friction loading distance b can be greater than or equal to the primary lever-rotating moment arm a.
