A telescopic spreader for lifting loads of various lengths i.e. load-holders or containers, comprising a main beam and within its longitude at least two opposingly movable telescopic beams. These have at their outer ends means for coupling to the load to be lifted. The main beam has extensions at its upper gable ends which extend out almost as far as that on the same side telescopic beam's  outer end when that telescopic beam is in its innermost position. Each extension  is designed to accept the extended inner end or that in the opposite direction extensible telescope beam when in its innermost portion. By the invention the forces the main beam are reduced thus rendering the beam a lighter weight.
