Abstract

1448843 Grabbing machines CATERPILLAR TRACTOR CO 24 Aug 1973 [25 Aug 1972] 07262/76 Divided out of 1448841 Heading E1F [Also in Division B8] A hydraulic excavating machine including a boom 16 a stick arm 12, an implement e.g. a bucket 28, and an assembly pivotally attached to the arm at 30 and interconnecting the stick arm 12 with the implement 28, has a cushioned stop 210 arranged to limit pivoting of the assembly in the direction of the arm 12. The cushioned stop 210 may be fixed to the assembly as at a trunnion support 22, where it is positioned to limit pivoting by contacting the arm 12.
