Abstract
1488497 Luffing arm apparatus O & K ORENSTEIN & KOPPEL AG 29 Nov 1974 [1 Dec 1973] 51882/74 Heading B8H An elevator comprises an elevatable arm which consists of arm parts 3, 6 which are fixed relative to each other, a platform 7 pivotally attached at 8 to arm part 6, and the arm part 3 is pivotally attached to a frame part 1a of the elevator at 4, the elevator further comprising a link arrangement which comprises an outer link member 10 which is pivotally attached at 9, 12 respectively to the platform 7 and to an intermediate link member 11 which is pivotally attached at 13 to the arm and an inner link member 15 which is pivotally attached at 14, 16 respectively to the link member 11 and frame part 1a. On elevating the arm by means of an hydraulic ram 5 the angular position of the platform 7 relative to the frame of the excavator remains constant, since the pivot points 8, 9, 12, 13 and 13, 14, 16, 4 are disposed at the corners of a parallelogram.
