Abstract
19,406. McMyler, J. Aug. 29. Cranes.-In apparatus in which a grab is suspended from a trolly travelling on a bridge and the sag of the operating-ropes is supported by carriers travelling intermediate of the trolly and the ends of the bridge, the sag-carriers are connected so as to move simultaneously in the same direction. The operating-ropes D, E of the grab C and the traversing rope F of the trolley B are supported on sheaves g<3> carried by auxiliary trollies G on each side of the main trolley. These trollies are connected to the main trolly by ropes J, which are fastened to fixed points at one end, pass round sheaves g<4> on the trollies G, and are connected at their other ends to the trolly B, so that when the trolly B is traversed the trollies G move at half the speed so as to be each always midway between the trolly B and the end of the beam. In the arrangement shown, the trollies G are connected so as to move together by a rope K which passes round sheaves M at the ends of the bridge A.
