Abstract

996,853. Telescopic crane - Jibs. M. HAGANES. April 21, 1964, No. 16490/64. Headings B8B and B8H. The sections 1, 2, 3 of a telescopic crane-jib are extended and retracted by an hydraulic ram 9, 10, which is connected between sections 1, 2, and wires 12, 14, which are attached to the outer end of section 1 and the inner end of section 3. As the ram expands pushing out section 2, section 3 is pulled out by the wire 14 which passes round a pulley 15 on the outer end of section 2. When the ram contracts, the wire 12 and a pulley 13 on the inner end of section 2 retract section 3. The jib may be mounted on a vehicle by a bracket 4 for luffing and slewing movements.
