Abstract

1,086,075. Counterbalancing apparatus. J. PRADON. April 18, 1966 [April 16, 1965], No. 16874/66. Heading B8B. [Also in Division E1] A machine, e.g. a bucket wheel reclaimer, comprises a support structure 1, a boom structure 2 and a counterbalance structure 5 having a counterweight 4, the boom 2 being luffed by a winch 6 via a cable 3. The end of the cable 3 opposite to that attached to the winch 6 is attached to a counterweight 7 vertically slidable on guides in the support structure 1. In operation the winch 6 winds in the cable 3 whereupon the weight 7 is raised into engagement with stops, after which the boom 2 is lifted. As cable is payed out the boom 2 is lowered until it is directly or indirectly supported on the ground whereupon the weight 7 moves downwardly to tension the cable 3 and support the weight of the boom 2, to maintain the stability of the machine. As the weight 7 is lowered, a cam surface thereon engages first a switch to de-energize the winch motor and secondly, in the case of an accident, a switch which de-energizes the whole machine. In the embodiment of Fig. 4 (not shown) the counterweight on the end of the cable is mounted at the outer end of the counterbalance arm and constitutes part of the main counterbalance weight.
