1. A lift truck for vehicles, comprising a telescopic support, two spaced axles projecting from one side of said support and two lifting arms projecting from said one side of said support between and substantially parallel to said axles, said telescopic support including a piston/cylinder unit including a power piston and a first cylinder movable relative to each other, and a second cylinder, said first and second cylinders being movable relative to each other, said first cylinder and said second cylinder each supporting one of said axles and one of said lifting arms, whereby said lifting arms can be urged aginst a vehicle wheel by retracting the telescopic support below the vehicle wheel axle.

Abstract
A lift truck for vehicles comprising a telescopic support. Two wheel-carrying axles extend from one and the same side of the support. Two lifting arms extend from said one side of the support between and parallel to the axles. When the support is contracted the lifting arms engage opposite sides of a vehicle wheel situated between them. Continued contraction of the telescopic support extends an upward component of force on the vehicle wheel and lifts it clear of the ground.

9. A lift truck for vehicles comprising a telescopic support, two spaced parallel axles extending from one and the same side of said telescopic support, said axles carrying wheels, two lifting arms extending from said one side of said telescopic support, said lifting arms being spaced apart and parallel to said axles, said telescopic support including a piston/cylinder unit including a power piston and a cylinder movable relative to each other, said piston and said cylinder each supporting one of said axles and one of said lifting arms, means for extending or contracting the telescopic support, whereby when the telescopic support is contracted, the lifting arms can be brought into engagement with opposite sides of the wheel of the vehicle to be lifted and whereby continued contraction of said telescopic support exerts an upward component of force on said vehicle wheel so as to lift the wheel.
