Abstract

792,685. Mobile cranes: EMANUEL, G., and EMANUEL, R., [trading as EMANUEL DI E R. EMANUEL & C. SOC. IN ACCOMANDITA SEMPLICE]. Nov. 30, 1955 [Dec. 2, 1954; Dec. 14, 1954; Jan. 5, 1955; Sept. 30, 1955], No. 34318/55. Class 78 (4). A portable gantry for lifting gear is supported at one end by a leg 1, Fig. 2, supported by wheels 6 and at the other end by legs 9 which can be raised from the ground and moved relatively to the gantry: this movement permits the legs 9 to clear part of the load, e.g. the wings V of an aircraft to be lifted. In the construction of Fig. 2 the legs 1, 9 are in pairs and the legs 1 are connected to a tractor 4 by a member 7 and by a pair of longitudinals 3 which straddle the nose of the aircraft. The legs 9 fold upwardly and forwardly about hinges below the beam 8 which can be slid back to overlie the member 7 when the lifting tackle 12, 12 is not in use. In the construction of Fig. 7 a pair of legs 21 can be folded by a ram 29 to lie against the beam 19 of the gantry which is turned about a hinge 20 on a column 15 by a ram 28. The column 15 can be luffed about a hinge 16 by a worm and wheel 24, 25 and is carried by a turntable 17 so that the gantry 19 can be turned through 180 degrees from the position shown and then, by conjoint operation of the worm drive 24, 25 and of the ram 28, may be lowered, while still horizontal to rest on the chassis 13 of the vehicle. The column 15 is normally stayed by a hinged back stay 26, 27 from an extension 17a of the turntable. In the construction of Fig. 8 a pair of gantry beams 55 are carried by vertically sliding collars 54 on transversely spaced posts 53 and are guyed by tackle 58. The front ends of the gantry beams 55 may be raised and lowered by hydraulic rams and the rear ends carry hydraulic rams 61 which can be folded about a pivot 63 by rams 61a to lie against the gantry beams. When not in use the gantry beams 55 can be swung about the column 53 to extend forwardly to rest on a portion 56 of the vehicle chassis. In a construction similar to that of Fig. 8 the gantry beams 55 can be locked in their rearwardly extending position by members operated by hydraulic rams. The tackle 58 may be operated by hydraulic rams carried on the beams 55. In the construction of Fig. 20 the transversely spaced beams 111 of a gantry may be pivoted about the rear axle of a tractor 114 by jacks 116 carrying wheels 117. This raises wheels 118 on legs 113 sufficiently high to clear the wing of an aircraft when the legs 113 are slid rearwardly along the beams 111. The tackle carried by the gantry beams may comprise stationary tackle, carriages running along the gantries, or carriages running on bridges extending between twin gantry beams and movable with carriages running on the beams. Dual controls for opposite directions of travel may be provided on the tractor vehicle.
