device and beam contrast for the correzzione that elastic structure which are load-bearing sleds operators.the flessotorsione a beam (bar) orizzontabile that leads to a mobile cantilever load can be canceled by downloading on a beam against the effect produced by the mobile load.the conditions of balance are: p x b = r1 x a1 + rn x a1.results: straightness and parallelism of sled movement along the axis - consistency of orthogonality of vertical motion (z axis) compared with the plan of reference - size less dethe crossbar. areas of intervention: machines that require precision of movement and position.the beam may be strong elastic deformation contrast essential to the proper functioning of the system provided that it is adhered to the constancy of pressure of reaction between the beams.
