Abstract

Improvements introduced in mechanisms for the control of the working depth of an excavator of the type that have a shovel or similar earthmoving tool mounted on the end of a boom structure mounted, in turn, together with a turret of control, in a frame structure, characterized by at least one duct foldable at least in parts along its length and filled with a fluid, said duct being attached to the boom structure in such a way that it will follow the movements thereof and that, at one or both ends thereof, it is connected or arranged, in such a way as to establish communication, to act on a receptacle, which, under the influence of fluid pressure, will activate a device designed to indicate the pressure exerted on the receptacle.
