Abstract
Official abstract text for this publication.
A sealed hydraulic tank system for a mining shovel ( 10 ) includes an upper tank ( 68 ) and a lower tank ( 70 ). An air bladder ( 69 ) system is coupled to the upper tank to exchange air between the tank system and the bladder. The tanks include baffles ( 100,102,104,106,108 ) which filter the hydraulic fluid and which direct fluid flow along an elongated path to allow for de-aeration of the oil in the tank.
