Drive-through versus roller
Roller systems, which require the disengagement of drive systems so that wheels can spin freely on rollers, are generally more compact and cheaper to build.
“The driver has to move up, disengage the drive train, then move up again for each axle. The whole process takes about eight minutes,” says Waystack. “But once you have the wheels on the roller, just keep washing until they’re clean. That’s ideal for heavy clay sites.”
The deciding factor is volume. If 25 or fewer trucks are washed per day, and if the site is dealing with heavy clay, roller systems can be cost-effective. For almost all other sites, drive-through is the way to go. Average wash time is 45 seconds, and the possibility of driver error is greatly reduced.
“Roller systems require training,” says Waystack. “Not releasing the truck from gear is a mistake that can really tear up the roller units.”
Whether roller or drive-through, most systems recycle water.
