Abstract

A levelling platform for levelling a ladder or the like, including a pair of laterally spaced apart uprights and an upper support arrangement arranged to engage with the uprights such that the ladder or the like can be placed on and supported by the upper support arrangement so as to be spaced from the ground, the arrangement being such that one part of the upper support arrangement is engaged by one upright, with a second part of the upper support arrangement being selectively engageable with one of a plurality of engagement points provided on the other upright to control/determine the vertical position of the second part relative to the first part, the plurality of engagement points being vertically spaced along the other upright such that the second part of the upper support arrangement can be positioned higher and lower than the first part of the upper support arrangement.
