Device for lifting a load, particularly for lifting a motor vehicle, of the type comprising: - a column with a carriage sliding along said column, - a structure, which is associated with said carriage, for supporting the load to be lifted, - means for moving said carriage along said column, thus causing the load supporting structure to rise and/or descend, wherein said supporting structure of the load includes: - a single supporting arm which, at a first end thereof, is articulated to said carriage, - a longitudinal arm which is associated with said supporting arm, at the other end of said supporting arm, so as to be able to rotate with respect to said supporting arm, - arms which are provided at one or, preferably, both ends of said longitudinal arm and which develop in a substantially transverse, or in any case angled, direction with respect to said longitudinal arm, said arms being provided and/or configured to be engaged by members to support and/or support the load to be lifted, and characterized in that said longitudinal arm is telescopic at one or, preferably, both of its two ends, and that the supporting structure comprises an articulated parallelogram configuration of which one side is defined by said supporting arm, said articulated parallelogram configuration of said supporting structure comprising: - a first side defined by said single supporting arm, - a second side, articulated at one end of the first side and defined by a portion of said carriage, - a third side, articulated at the other end of the first side, and defined by a portion of said longitudinal arm, and - a fourth side consisting of a secondary arm configured so as not to have any substantial load-bearing function and configured to define, with the other three sides, said articulated parallelogram structure. - a column with a carriage sliding along said column, - a structure, which is associated with said carriage, for supporting the load to be lifted, - means for moving said carriage along said column, thus causing the load supporting structure to rise and/or descend, wherein said supporting structure of the load includes: - a single supporting arm which, at a first end thereof, is articulated to said carriage, - a longitudinal arm which is associated with said supporting arm, at the other end of said supporting arm, so as to be able to rotate with respect to said supporting arm, - arms which are provided at one or, preferably, both ends of said longitudinal arm and which develop in a substantially transverse, or in any case angled, direction with respect to said longitudinal arm, said arms being provided and/or configured to be engaged by members to support and/or support the load to be lifted, - a single supporting arm which, at a first end thereof, is articulated to said carriage, - a longitudinal arm which is associated with said supporting arm, at the other end of said supporting arm, so as to be able to rotate with respect to said supporting arm, - arms which are provided at one or, preferably, both ends of said longitudinal arm and which develop in a substantially transverse, or in any case angled, direction with respect to said longitudinal arm, said arms being provided and/or configured to be engaged by members to support and/or support the load to be lifted, and characterized in that said longitudinal arm is telescopic at one or, preferably, both of its two ends, and that the supporting structure comprises an articulated parallelogram configuration of which one side is defined by said supporting arm, said articulated parallelogram configuration of said supporting structure comprising: - a first side defined by said single supporting arm, - a second side, articulated at one end of the first side and defined by a portion of said carriage, - a third side, articulated at the other end of the first side, and defined by a portion of said longitudinal arm, and - a fourth side consisting of a secondary arm configured so as not to have any substantial load-bearing function and configured to define, with the other three sides, said articulated parallelogram structure. - a first side defined by said single supporting arm, - a second side, articulated at one end of the first side and defined by a portion of said carriage, - a third side, articulated at the other end of the first side, and defined by a portion of said longitudinal arm, and - a fourth side consisting of a secondary arm configured so as not to have any substantial load-bearing function and configured to define, with the other three sides, said articulated parallelogram structure.
