Walking Floor Trailer Monitoring: See Where Every Load Came Off

A walking floor trailer unloads itself, which is the whole point of it. Monitoring the floor shows when it ran and where, so you know every load came off where it was supposed to. We set it up for haulers across Georgia, South Carolina, North Carolina, Tennessee, Virginia, Alabama, Florida and Mississippi.

How can I see when and where my trailer was unloaded?

A walking floor trailer, also called a live floor or moving floor trailer, has floor slats that move back and forth to walk the load out the back. Chips, mulch, scrap, trash and crops come off without a dump body or a loader. A GPS tracker shows the trailer stopped at a site. Monitoring the floor shows it actually unloaded there, with the time and how long it took.

For haulers paid per load, or customers who want proof of delivery, that is the record that settles the question.

What is PTO monitoring on a walking floor trailer?

The trailer's floor runs on hydraulics, but the trailer usually has no pump of its own. The pump is on the tractor, driven by the engine through a power take-off, or PTO, as part of what is called a wet kit. The driver engages the PTO and the hydraulic lines to the trailer drive the floor. So there are two places to monitor: the tractor's PTO, or the hydraulic line on the trailer itself.

Which is better, monitoring the tractor or the trailer?

How is walking floor monitoring hooked up?

There are a few ways to give the tracking device a reliable on and off signal, and the right one depends on the truck:

On the trailer side, the switch and its wiring have to live with the dust, chips and pressure washing these trailers get, so they are mounted out of the load's path and sealed. Truck-side wire colors are in our Vehicle Wiring Database.

How do you know the monitoring is right?

We run the floor, stop it and run it again, and confirm the platform shows each run at the right time and place. If the trailer is monitored on its own, we also check it reports with a different tractor hooked up. See PTO and equipment integration for the other trucks we wire this way.

Common questions

Questions We Get Asked

Can a GPS tracker show when a walking floor trailer unloaded?

Yes, through the tractor's PTO signal or a pressure switch on the trailer's floor hydraulics, tied to the tracker.

What if different tractors pull the trailer?

Then monitor the trailer itself, with a pressure switch on its floor hydraulics and a tracker on the trailer.

Do you install trailer trackers as well?

Yes. See our trailer GPS tracker page.
