A tank cleaning system used for cleaning large crude oil storage tanks. The cleaning system includes a large rail vacuum pipe, a high pressure air line and a high pressure steam line connected to an air/steam mixing box. The mixing box includes an air nozzle connected to the air line, a steam nozzle connected to the steam line and a mixing box vacuum tube connected to the rail vacuum pipe. The rail vacuum pipe includes a steering, guide rail mounted thereon for receiving a swivel wheel. The swivel wheel is attached to a door opening bracket. The door opening bracket is attached to opposite sides of a door opening in a side of the tank. The steering, guide rail pivots on the swivel wheel and allows an operator, standing outside the tank, to move the mixing box back and forth, left and right for engaging and vacuuming up the sediment in the bottom of the storage tank. |
