Abstract

1,157,488. Shovel excavators. WARNER & SWASEY CO. 25 Nov., 1966 [4 April, 1966], No. 27954/68. Divided out of 1157486. Heading E1F. To allow of variation of the speed-load lifting relationship of a boom of a materialhandling machine, e.g. a back hoe shovel excavator, the boom 80 of the machine is supported for rotation about a pivot 51 on the superstructure of the machine by a support 60 pivotally mounted on the pivot 51, the boom being pivotally dependant at 61a from the support and angularly aidjustable with respect to the support by a ram 62 connected between the support and the boom. Thus the length of the lever arm between the pivot 51 and the line of thrust of a ram 53 controlling vertical swinging of the boom may be varied to allow of either low torque, large amplitude, fast movement or high torque, smaller amplitude, slower movement, or intermediate variants, as desired of the pivotal movement of the boom.
