Abstract

1,212,622. Shovel loaders. CATERPILLAR TRACTOR CO. 1 Aug., 1968 [8 Sept., 1967], No. 36728/68, Heading E1F. A control system for automatically causing movement of the bucket and the lift arms of a shovelling machine between predetermined positions in the excavating cycle of the machine has tilt and lift control means 51 that on being manually set to cause tilt and lift of the bucket are held by detents 53', 54' and 56' to cause continuance of the required until the detents are freed from the control means on completion of the movements. The system is a combination of the control systems of the referred to Specifications 1,060,347 and 1,163,467.
