Abstract

1,169,060. Shovelling machines. PACIFIC CAR & FOUNDRY CO. 13 Nov., 1967, No. 51638/67. Heading E1F. The gravitational torque of the components of a shovel-carrying boom assembly mounted on a .tractor is at all times balanced by a pressurized gas-containing, closed circuit, pistoncylinder arrangement 48 acting between the tractor and the boom so that the full engine power applicable to rams 24 controlling vertical swinging of the boom can be utilized in overcoming the torque set up by the load in the bucket during breaking out and raising of the loaded bucket.
