Abstract (en)
[origin: EP0894915A1] The invention relates to a concrete supply arm, to be mounted in particular on vehicle-transported concrete pumps, having several sections (11,12) and articulating joints between said sections. In this arm the relative movement of the sections (11,12) is performed, in correspondence of at least some of the articulating joints of the arm, by means of actuator mechanisms (23) consisting of a worm gear actuated by a hydraulic motor. Conveniently said actuators also comprise a locking brake. <IMAGE>
