Claim:
An electric fork-lift truck, comprising a unitized body equipped with one or more directional rear wheels and with a safety roof and including the passenger compartment for the operator with related controls and hydraulic and electric circuits, as well as compartments for housing an electric battery and a ballast and a mast extended in height and which in case can be elongated vertically, whereon a slide is assembled sliding in vertical direction and bearing front forks for gripping and supporting the load to be moved, characterized in that it comprises an intermediate frame ( 14 ), bearing idle or driving front wheels ( 21 , 22 ) of the truck and assembled with respect to said body ( 11 ) in an oscillating way around a transversal axis (X-X) parallel to the axis (Y-Y) of said front wheels, in that an operating-cylinder ( 30 ), operatively connected in the truck's hydraulic circuit, is articulated on one side with respect to said body ( 11 ) and, on the other one, with respect to said intermediate frame ( 14 ), by respective axes parallel to said transversal axis (X-X) so that said unitized body ( 11 ) equipped with said intermediate frame ( 14 ) with front wheels, constitutes a structural autonomous and movable/semi-movable unit ( 40 ), suitable for storage and transportation and wherein a pitch or a wheelbase between the front wheels and the rear wheel or wheels is selectively variable by oscillating said intermediate frame ( 14 ) around said transversal axis (X-X) by said operating-cylinder ( 30 ) and in that said mast ( 12 ) is dismountably fastened to said intermediate frame ( 14 ) so that said mast ( 12 ) can be made to oscillate integrally with the intermediate frame ( 14 ) itself around said transversal axis (X-X), by said operating-cylinder ( 30 ) to swing forwards and rearwards, with both idle ( 21 ) and driving ( 22 ) front wheels, whereas said mast ( 12 ) can be disassembled and assembled easily with respect to said intermediate frame ( 14 ).
