Title: LOAD MANIPULATOR WITH IMPROVED BALANCING
Abstract:
A load manipulator comprising a boom arm (1) and a steering arm (3) that are parallel to each other, a balancing arm (2), and a counterbalance (4), thereby forming a deformable parallelogram, a substantially horizontal pivoting axis on which one of the arms of the parallelogram is articulated, and balancing means (8) applying pressure to a point of application for compensation (C) to compensate for the force of the load, said point being a point on the steering arm (3) and a point on the counterbalance as it is always aligned with a point (M) on the balancing arm, upon which the force of the load and the axis of rotation are applied, in which the balancing means (8) comprise a first counterweight (10) and a second counterweight (12) and a cylinder for compensating the value of the force of the load, the first counterweight (10) and the cylinder applying pressure to the point of application for compensation (C) and the second counterweight (12) exerting pressure on the boom arm (1).
