Abstract

877,174. Supplying electric power to overhead crane trolleys. SMITH (KEIGHLEY) Ltd., JOHN. Nov. 2, 1959 [Nov. 28, 1958], No. 38387/58. Class 78 (4). In a travelling overhead electric crane power is supplied to the motors on the crab 4 through an insulated cable 10 which is supported during movement of the crab by a trolley 6 moved by a rope 13 attached to the crab at 14. As the crab 4 moves the full distance between rails 1, the trolley 6 is drawn a distance equal to half the distance between the rails 1, along the rails 5, by the rope 13. Thus, there is never any slack in the cable 10 between a fixed junction-box 11 and the point 14 where the cable is attached to the crab 4. Means may be provided for adjusting the length of the cable 10 and the rope 13.
