Abstract: A lifting apparatus includes a mast that is mounted orthogonally (perpendicularly) to the plane of a base supported by wheels. A beam and tension member are connected pivotally to the mast and further to a carriage assembly support in such a manner that the support and mast maintain a parallel relationship, as do the beam and tension member. A lifting ram is pivotally connected to the mast and to the telescopic beam. During a load lifting operation, the resulting parallelogram configuration of the mast, carriage assembly support, beam, and tension member serve to maintain the tines of the carriage assembly in a plane parallel to the base of the lifting apparatus as the carriage assembly is arcuately raised. The carriage assembly and tension member may be removed in order for the mast and boom to be used as an engine hoist, and the apparatus may be further used as an engine work stand by installing a plate on the engine which is pivotally installable on the mast at the ram attachment point.
