A vehicle lift designed to be arranged on a floor and including: • an upper platform that is substantially rectangular in shape and that has a substantially flat and horizontal upper surface, two longitudinal edges and two transverse edges, • a supporting structure designed to selectively raise and lower said upper platform relative to the floor between two predetermined limit positions, • at least one substantially horizontal supporting arm with a longitudinal axis, which has a free end and an end connected in an articulated manner to said upper platform, as well as a lower face and an upper face, wherein said supporting arm is mounted in a pivotable manner on a U-shaped supporting-element support fixed to one of said longitudinal edges of said upper platform, wherein said articulated end of said supporting arm is able to pivot about a vertical axis that runs through said supporting-element support so as to be able to turn selectively between a rest position in which said supporting arm is folded against one of the longitudinal edges and a position of use, • locking means (51, 52, 53, 54, 55) designed to lock selectively and automatically said supporting arm in a position of use, said vehicle lift being characterized in that said locking means (51, 52, 53, 54) include: • a fixed locking element fixed to said support element so as to be traversed by said vertical axis, • a movable locking element that can translate along the axis of said supporting arm, wherein said movable locking element is fixed to • a pull strip provided with a handle, which are both movable in translation along said axis, wherein said pull strip is arranged inside said supporting arm and said handle extends said pull strip outside said supporting arm so as to be able to move said pull strip, by a pulling effort exerted on said handle along the axis Z, and thus to move said movable locking element from a locking position, in which said fixed locking element and said movable locking element are in contact and mutually engaged, to an unlocking position, in which said fixed locking element and said movable locking element are spaced apart and disengaged with respect to each other, wherein the return from the unlocking position to the locking position is effected by return means that cooperate with said pull strip when the handle is released. • an upper platform that is substantially rectangular in shape and that has a substantially flat and horizontal upper surface, two longitudinal edges and two transverse edges, • a supporting structure designed to selectively raise and lower said upper platform relative to the floor between two predetermined limit positions, • at least one substantially horizontal supporting arm with a longitudinal axis, which has a free end and an end connected in an articulated manner to said upper platform, as well as a lower face and an upper face, wherein said supporting arm is mounted in a pivotable manner on a U-shaped supporting-element support fixed to one of said longitudinal edges of said upper platform, wherein said articulated end of said supporting arm is able to pivot about a vertical axis that runs through said supporting-element support so as to be able to turn selectively between a rest position in which said supporting arm is folded against one of the longitudinal edges and a position of use, • locking means (51, 52, 53, 54, 55) designed to lock selectively and automatically said supporting arm in a position of use, • a fixed locking element fixed to said support element so as to be traversed by said vertical axis, • a movable locking element that can translate along the axis of said supporting arm, wherein said movable locking element is fixed to • a pull strip provided with a handle, which are both movable in translation along said axis, wherein said pull strip is arranged inside said supporting arm and said handle extends said pull strip outside said supporting arm so as to be able to move said pull strip, by a pulling effort exerted on said handle along the axis Z, and thus to move said movable locking element from a locking position, in which said fixed locking element and said movable locking element are in contact and mutually engaged, to an unlocking position, in which said fixed locking element and said movable locking element are spaced apart and disengaged with respect to each other, wherein the return from the unlocking position to the locking position is effected by return means that cooperate with said pull strip when the handle is released.
