Engineering the future of intelligent trailer security and active theft prevention.
EM6000 Auto locks a trailer's landing gear physically and electronically, so an unauthorized tractor cannot couple to it and drive off. This is prevention built into the trailer itself—not a tracking dot that shows up after the theft is already done.
Reports a trailer's location after it has already been hooked up and moved.
Recovery starts once the asset and its cargo are already gone.
Locks the landing gear so an unauthorized tractor cannot hook up at all.
The theft is stopped at the coupling point, before the trailer ever leaves the lot.
Move from recovery to prevention.
EM6000 Auto puts a physical barrier between unauthorized tractors and your trailer.
Cargo theft is not a rare event anymore, and most of it does not happen on the highway. It happens while a trailer sits still.

Why traditional tracking falls short
A standard GPS tracker reports where a trailer is. It does not stop an unauthorized tractor from hooking up in a drop lot at 2 a.m. and driving away with it.
By the time the alert fires, the trailer and cargo are already moving.
Many cargo theft targets trailers sitting still—in a drop lot, distribution yard, warehouse area, or unsecured parking location—not trailers already in transit.
That is exactly where a trailer immobilization system matters most.
EM6000 Auto turns the landing gear itself into the access control point. That stops unauthorized coupling and yard movement at the source.

Intelligent trailer immobilization
Instead of simply monitoring a trailer after movement begins, EM6000 Auto integrates security directly into the landing gear. The result is a physical and electronic barrier against unauthorized coupling.

Smart access control
The system locks the trailer's landing gear in place so an unauthorized tractor cannot hook up and pull away. The lock mechanism sits inside the landing gear housing rather than as an exposed add-on. That is why it is harder to spot and harder to defeat.
When an authorized tractor disconnects from the trailer, the system locks down automatically. There is no separate step for a driver or yard employee to remember, which closes a gap that a lot of manual security processes leave open.
Authorized unlocking works through whichever method a fleet security team assigns:
The system immediately flags break-in attempts and unusual movement. Combined with live GPS and geofence tracking, your security team knows the exact moment a locked trailer is tampered with - not the next morning when it's already too late.
Real-time security awareness
Tamper + GPS + geofence monitoring
EM6000 Auto adds an active security layer to every trailer, helping fleets move from reactive recovery to proactive prevention without slowing down everyday operations.
Respond after unauthorized movement has already occurred.
Block unauthorized coupling before the trailer can leave the yard.
Prevention Over Recovery
Recovery teams work a case after cargo is already gone. A trailer immobilization system removes the hookup that theft depends on in the first place.
Operational Speed
Legitimate drivers unlock in seconds through app, Bluetooth, RFID, or keypad. Security does not have to come at the cost of drop-and-hook speed.
Risk & Insurance
When you prevent unauthorized hookups, you get fewer claims and avoid wasting time tracking down stolen freight. Plus, you have solid evidence to negotiate better terms with your insurer at renewal time.
Real-Time Visibility
Real-time GPS and geofence alerts flag unexpected movement or boundary crossings the moment they happen. This gives security teams a chance to respond before a trailer leaves the area.
Yard Security
Trailer-mounted power means the system stays locked and active whether a tractor is attached or not, which is exactly the condition trailers sit in most of the time they are targeted.
Asset Protection
Asset protection directors get a consistent, fleet-wide control they can point to, instead of relying on yard checks, cameras, or driver habits alone.
Everything you need to know about Trailer Immobilization System to Prevent Unauthorized Movement.
It physically and electronically locks the landing gear in place so an unauthorized tractor cannot couple to the trailer at all. Instead of tracking a trailer after it is stolen, the lockdown prevents the hookup that theft depends on.
Yes. The immobilization system runs on its own trailer-mounted power supply. That is why it stays locked and active whether or not a tractor is connected, including trailers parked in a drop lot overnight.
The lock mechanism is built into the landing gear housing rather than left exposed. The system includes tamper and motion detection that flags forced entry attempts and unexpected movement in real time.
They solve different problems. GPS tracking tells you where a trailer went after it was taken. An immobilization system is built to stop the unauthorized hookup before the trailer ever leaves, and works best paired with GPS and geofence alerts rather than replacing them.
Authorized drivers and yard workers unlock it however the fleet's security team has set up: mobile app, Bluetooth, RFID card, one-time-password keypad, or a remote security portal.
