Abstract

1,262,553. Telescopic crane booms. COLES CRANE Ltd. 17 Aug., 1970 [21 Aug., 1969], No. 41782/69. Heading B8B. A crane boom comprises teleecopic sections A1, A2, A3 extended and retracted by conjointly operated ropes (C3), (C4), Fig. 1 (not shown), so that as section A2 moves out of section A1, section A3 moves an equal amount out of section A2. A luffing rope B3 is attached at B4 to section A3, passes around pulleys B2, B5 on a strut B1, around pulley B6 at the outer end of section A1, around pulleys B7 at the inner end of section A2 and is attached at B8 to the outer end of section A1. This arrangement results in automatic compensation of the length of the luffing rope B3 as the boom is telescoped. A similar arrangement for the load rope (Dl), Fig. 3 (not shown), simultaneously provides similar automatic compensation for its length.
