Abstract

Safety device against hand grippers in a mobile concrete mixer, especially one intended to prevent hand catching in the extension maneuver of the unloading channel of a concrete mixer, more particularly those that, mounted on a truck, are intended to transport the concrete made in a concrete mixer to the construction site, in which the concrete mixer consists of a rotating tank and a concrete discharge channel, which, being inclined, is constituted by a half-level superior to that which is superiorly faced by bending a lower half-shell which is hinged at its upper end to the lower end of the upper half-shell, this folding arrangement permitting elusive parts protruding from the concrete mixer during its transport and which, by lowered the lower half-shell around the axis of the articulation with the upper half-casing, said lower half-casing is aligned with the upper channel, constituting between the discharge channel in the work of the transported concrete, characterized in that it consists of a pivot which, requested by a spring, automatically tends to be located between the two edges of the half-shells, in the position of folding them, and at a point end near one of the two joints of the half-shells with each other, which prevents such edges from coupling with each other to form the discharge channel and allows them to establish a safety opening of sufficient amplitude to avoid damaging a hand accidentally located in such place at the end of the lowering half-lower maneuvering maneuver, at which time the pivot is removed with one hand while the other hand is acted on said lower half-raise by raising it to allow said removal of the pivot with the other hand, after which it descends to align it with the other semichannel and to connect the edges of both half-channels to make the unloading channel usable.
