The skew wheel work conveyor is a basic system that conforms to the arc spray pattern requirements and is used frequently for in-line systems where blast cleaning, wheel or airblast, and coating are on a single line. The rear wheels power the work rotation and the front wheels are on a slight angle to the work to produce a small amount of travel forward for each revolution of the work.
The work cart style places the submersible pump on carts which have two sets of wheels - one set on tip to rotate the work, and the second set for the cart travel. The carts are moved by a chain and a gear motor. The rpm of the rotation and the speed of the chain are independently controlled to produce the exact pattern spacing required to match the spray pattern overlap and the coating thickness desired. (see below)
The coating thickness is typically measured using a magnetic coating thickness indicator (shown below) or a micrometer.
