This is an elevator platform for lopping in forestry work, the platform being fifteen or so square metres in size, and fixed on a tractor by means of two supports which make it possible, with the aid of two manual winches, to raise this platform to a height of five metres and to provide two or four workers with a work surface on which they can carry out, under optimum conditions, lopping up to nine to ten metres. <IMAGE>
