Abstract:
A system for cleaning a plurality of grates, each grate being of the type having a corresponding predetermined length characteristic, the system comprising:a first power wash portion for applying a pressurized wash fluid to a first side of each of first and second grates, the first and second grates being of the type that have waste paint dried on the respective first sides thereof, the pressurized fluid from said first pressure wash portion being applied at a pressure sufficient to blast the waste paint off of the first side of each of the first and second grates; a second power wash portion for applying a further pressurized wash fluid to a second side of each of the first and second grates, the first and second grates being of the type that have waste paint dried on the respective second sides thereof the pressurized fluid from said second power wash portion being applied at a pressure sufficient to blast the waste paint off of the second side of each of the first and second grates; and a transport arrangement for defining a grate path through the first and second power wash portions, said transport arrangement further having a grate drive arrangement for engaging the first grate and urging the first grate while the first grate is in a vertical orientation along an initial portion of the grate path for a distance corresponding to the length characteristic of the first grate, and subsequently urging the second grate while the second grate is in a vertical orientation along the initial portion of the grate path for a distance corresponding to the length characteristic of the second grate, whereby the urging of the second grate along the first portion of the grate path applies a linear force to the first grate that urges the first grate along the remainder of the grate path.
