Power for the trailer’s floor and other mechanisms comes from a hydraulic ‘wet kit’ on the tractor. “Experience has taught us that the pump runs for quite a long time for a moving-floor, so we help our customers chose a good, durable pump,” says Santry.
He identifies the clean-out mechanism as particularly critical. It is essentially a movable front bulkhead with a tarpaulin-like sheet attached and resting on the trailer’s floor. The weight of the load on the sheet “walks” the bulkhead to the rear of the body as the load discharges; a hydraulic winch retracts it for the next load. The difficult bit is the seal between the bulkhead and the trailer sides, achieving a good clean-out to prevent cross-contamination between loads. “We’ve spent a long time getting it right, so we know the pain of the learning curve that others are now going through,” says Santry, adding: “Ours now works well 99% of the time for 99% of products.”
