Abstract

1365901 Taking up slack in flexible elements; luffing booms WARNER & SWASEY CO 14 July 1971 [10 Sept 1970] 32971/71 Headings B8B and B8H A telescopic boom assembly comprises an inner section 28 slideable within an outer section 30 and at least one flexible power conducting hose 100 coupling fixed power conduits on both boom sections, the looped hose 100 being restrained to a fixed path by a guide channel in a hose trough 80 secured to the outer boom section and a spring loaded roller 134 movable along the channel. The roller 134 operates on the loop 96 of the hose only during the outer half of movement of the inner boom section. Each boom section comprises triangularly disposed tubular longitudinal members 46, 50 interconnected by plates, the tubular members of each section being engaged by guide rollers on the other section. The tubular members 50 of the inner boom section constitute conduit means for conducting pressurized fluid from the hose 100 to a further hose at the end of the boom for operating a handling apparatus thereat. The boom is hydraulically extendable-retractable and is mounted on a vehicle for luffing and slewing motions.
