This option is required if you are going to use your conveyor as a front wheel pull application. Front wheel pull requires that we add additional height to the inside guide rail. If this option is ordered, PECO will add a piece of 3/4 x 3/4 square tubing to the inside guide rail. The extra height of 4 3/4” will insure that the front tire is less likely to twist on the conveyor, thus preventing vehicles from jumping the conveyor track. Also, the track width is reduced to 12”. Note: Front wheel pull is not recommended for conveyors over 90’ in length.
