Abstract
741,213. Breakdown cranes. DAIMLERBENZ AKT.-GES. Oct. 29, 1953 [Oct. 29, 1952], No. 29979/53. Classes 78 (3) and 78 (4). A breakdown crane comprises a single-axle trailer provided with car lifting means 6, initially adjustable towards the car, lifted by a cable 19 and pivotable into a position vertically above the axle. The hook 6, Fig. 1, is at one end of arms 7, pivoted to a sleeve 9 slidable on an upright 10 secured to the axle 1 of the trailer which is connected by divergent poles 3 to a tractor 5. The arms 7 are also connected by links 15 to the upright. The hook is raised over the axle for towing the car by the cable 19 which is anchored at 13 to the top of the upright and passes over pulleys 16, 20, round a pulley 24 carried by arms 25, over a pulley 28 on supports 12, and round a pulley 22 to the winch 21. The arms 25 are mounted on the axle 1 and carry angularly adjustable groundengaging arms 26. As the winch is actuated the pulley 24 is raised to cause the arm 26 to engage the ground and then to lift the hook supporting the car until the arms 7 and links 15 are vertically over the axle 1 where they are secured by a bolt. During transport the member 26 is adjusted relatively to the member 25 into a horizontal position. The supports 12 can be disengaged from the pole 3 and the parts folded down when not in use. In an alternative form (Fig. 5, not shown) an auxiliary post carrying a sleeve for the hook is pivoted to the top of the upright and is swung to and from the vertical for towage or load-engaging respectively by a screw and nut. The hook is raised by a cable anchored to a cross-head slidable on the upright, urged upwardly by a spring and having a toggle connection with a ground-engaging support. In another form (Fig. 8, not shown) the car is engaged by a hook on a pivoted jib which is swung by a cable to bring the hook over a vertically-adjustable support over the wheel axle. The support is then adjusted to engage and take the load. In another form, Fig. 9, the hook 96 is attached to a pulley 95 which is suspended by a cable from the top of uprights 90, the cable passing over a pulley 97 to a winding drum 99. The uprights and a pair of jib members are tiltable forwardly, by releasing a locking device 92, or by a screwed spindle, to engage a lifting framework 107 secured to the car by wedges and chains. The end of the framework is lifted by the hook and the supports 90 are tilted back so that a ball 108 beneath the end of the framework engages in a socket in a member slidable on the uprights and is locked in position. Adjustable groundengaging members 103 are provided.
