Abstract
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.
