A dual-cylinder tilting assembly for use with a vacuum tank. The tank is mounted on a frame, such as a trailer or a truck bed, at a pivotal connection at its end. A door is disposed near the end with the pivotal connection. The tilting assembly is at the other end, and has two cylinders with their rods facing alternate directions. The rod of one of the cylinders is pivotally attached to the frame and the rod of the other is pivotally attached to the tank. The barrels of the two cylinders are joined physically and hydraulically linked. The cylinder assembly, when fully extended, extends approximately three times its unextended length and tilts the tank at an angle of thirty to fifty degrees.

Cylinder assembly for tilting a vacuum tank

A system for controlling pressure to a vacuum tank. The system comprises a conduit disposed between the vacuum tank and a blower. The conduit has a sealable connection disposed along its length between two sections that are geometrically conforming. The connection may be conical and threadless. Tilting the vacuum tank relative to the blower causes the connection to separate, allowing pressure within the vacuum tank to equalize with atmospheric pressure. Filters may be provided on each side of the connection for removing particulates from air evacuated from the tank.
