Abstract
Abstract To enable a conventional forklift truck with front mounted forks to be used as a side lift truck the invention provides an auxiliary carriage arrangement comprising a longitudinal member, supporting arms attached to said longitudinal member, means for fixing said longitudinal member to the lifting panel of the forklift truck so that it is perpendicular to said panel, and at least two transverse arms each carrying at least one pivoting wheel and mounted themselves in pivotable relationship to the supporting member so that they can swing downwards into a position in which they are substantially parallel to the supporting arms, the pivoting wheels numbering at least three and being located in such fashion as to constitute a stable support for the truck.
