PCT No. PCT/SE81/00115 Sec. 371 Date Nov. 12, 1981 Sec. 102(e) Date Nov. 12, 1981 PCT Filed Apr. 13, 1981 PCT Pub. No. WO81/03013 PCT Pub. Date Oct. 29, 1981.A telescope spreader for lifting loads of various lengths i.e. load-holders or containers, comprising a main beam (20) and within its longitude at least two opposingly movable telescope beams (21 and 22). These have at their outer ends means (23) for coupling to the load to be lifted. The main beam (20) has extensions (28) at its upper gable ends which extend out almost as far as that on the same side telescope beam's (22) outer end when that telescope beam (22) is in its innermost position. Each extension (28) is designed to accept the extended inner end (27) or that in the opposite direction extensible telescope beam (21) when in its innermost portion. By the invention the forces P1, P2 working upon the main beam are reduced thus rendering the beam a lighter weight.
