Abstract
A hydrovac unit with a mud tank and water tank arranged symmetrically, so that the center of gravity does not substantially shift forwards or backwards during operation. The mud tank may be located inside the water tank. The mud tank may be supported and reinforced by external ribs, which may be fixed to the mud tank. The water tank may be formed by a rear face attached to the mud tank and a cylinder portion, the mud tank and rear face sliding into the cylinder portion for assembly and secured in place. The contents of the hydrovac unit may be dumped by tilting using a hoist. The tank assembly may be heated and insulated.
Claims20
A tank configuration for a hydrovac, the tank configuration including a water tank and a mud tank, the water tank surrounding the mud tank at least partly on lateral sides of the mud tank, the lateral sides of the mud tank connecting to form a bottom of the mud tank, the mud tank being supported by ribs within the water tank, and the ribs defining holes for allowing water flow through the ribs.
A hydrovac unit having a tank configuration including a water tank and a mud tank, the water tank surrounding the mud tank at least partly on lateral sides of the mud tank, the tank configuration being mounted on a hoist for dumping from at least the mud tank.
A hydrovac unit having a tank configuration including a water tank and a mud tank, the tanks being shaped to define a level orientation such that, when fluid is within each of the water tank and mud tank up to respective horizontal planes in the water tank and the mud tank, the fluid within each of the water tank and mud tank defines respective centers of volume, the centers of volume having respective positions in a forward-backward dimension that substantially coincide and are substantially independent of respective heights of the respective horizontal planes, in which the tank configuration is mounted on a hoist for dumping from at least the mud tank.
