Abstract

Jack of elevation, being of which it is constituted, by means of four determining arms of a deformable parallelogram, in which two of its vortices are capable of approaching or distancing by the effect of a screw-nut assembly, while its other two vortices determine respectively the one of support on the ground and the one of unión to the element to elevate, preferably a motor vehicle, and incorporating in the ends of its determining arms of its superior vortex carved determinants of asymmetric teeth that mesh with each other and that determine in the extension of the cat a lateral displacement of said vertex, characterized in that the lower extremities of its other two arms, the determinants of the vertex of support on the ground, are directly related to each other by means of a bolt or transverse axis which, in turn, is installed on the own base of support of the cat, so that said lower arms are susceptible s of free swinging between them and jointly, of free tilting with respect to the support base, all in order that the fixed lateral tilting determined by the characteristics of the toothing of the upper arms, is corrected towards more or less, in function of the needs of the load to be lifted, and by the free articulation existing in the lower vertex of the parallelogram.
