Abstract

Weight balancer, essentially characterized by being formed from a stiffened column to a support base optionally provided with wheels for transport, said column being an axial connection element and in a freely rotating state for a second column where it is installed parallel to it in an articulated manner, a pressure cylinder whose rod attacks inferiorly on a prismatic body displaceable by this second column; it being provided that such body comprises a vertically arranged slit slot where sliding and guiding pairs of bearings are mounted horizontal and parallel axes of the second column, the upper shaft, in turn, articulation point for a carrier arm at one end of a counterweight and in the opposite of another articulation point for the extremity of a vertical lever where the load to be balanced is opposed, also counting this lever with manually operated handles and the control of the pneumatic circuit for the cylinder; with the particularity said lever to receive at a relative distance from its upper articulation the relation also articulated in a second arm which, parallel to the first, disposes in opposition of an axis with bearings that slide and guide in a new slot horizontal and horizontal also practiced in the aforementioned prismatic body, this axis being the point of articulation for a final lever that serves as an articulated link between the parallel arms, forming a deformable parallelogram with the vertical displacement of the prismatic body due to the thrust to which the cylinder of the pressure.
