Abstract
933,039. Mobile cranes. E. NATINO. June 30, 1961 [July 2, 1960], No. 23640/61. Class 78 (4). The load-hook 20, Fig. 1, of a mobile crane is located substantially centrally of the crane so that the load is equally distributed over the wheels. As described, the crane has two fixed wheels and a steerable driven wheel 3. The structure 4 which in addition to the wheel 3 carries a winch 6 and motor 5, is pivoted to the crane structure by ball bearings 10. Handles 7 and brakes 8 control the crane, the driving wheel and winch of which can be driven in either direction either independently or simultaneously. Rotatable brackets 21 support the load during transit. In a second embodiment the track of the crane is variable, a wheel 14, Fig. 4, being swung in or out when clamps 39 connecting a leg 13 to the frame 11 are loosened. A lever linkage 13, 35, 32, Fig. 5, pivoted at 36 to a member 12 maintains the wheel 14 parallel to the wheel 2 when the member 12 is swung to change the track. A bracket 37 linked to the lever 35 by a link 38 carries the load sheave 17 and ensures that it remains centrally disposed with respect to the wheels when the track is altered. Both embodiments may have a platform for the driver or he may walk.
