Trailer and container tracking
Track trailers and containers wherever they are, with alerts when doors open, conditions change or the unit moves without authorisation.
Asset handover record
One unit. Several points of responsibility.
A trailer or container has its own journey, even after the truck leaves.
Truck location and unit location answer related but different questions. Asset-mounted tracking keeps the unit's own record continuous through each handover.
Prepared illustration
The drawing scrolls sideways. Everything in it is written out below.
At loading
Identify the unit and the measurements its cargo requires. Temperature, humidity and door information can be included where the appropriate sensors are fitted.

- Trailer TR-118 (example)
- Door
- Open, loading bay
- Sensors fitted
- GPS, door, temperature
Text version of this diagram
A trailer drawn from the side with the tracker, door sensor and internal sensor positions marked, above a four-stage custody rail: loading, transit, depot and handover.
- At loading. Identify the unit and the measurements its cargo requires. Temperature, humidity and door information can be included where the appropriate sensors are fitted. Written example: Unit — Trailer TR-118 (example); Door — Open, loading bay; Sensors fitted — GPS, door, temperature.
- In transit. Follow the reporting position and compare movement against the expected journey. The unit reports for itself, so its record does not depend on which truck is pulling it. Written example: Reporting from — Kafue Road (example); Last update — 09:31, six minutes ago; Door — Closed since 07:55.
- At the depot. Check where the trailer or container was left, including when it is no longer attached to a truck. Power and device arrangements are chosen for the periods the unit needs to operate independently. Written example: Position — Depot yard, bay 7 (example); Detached — Parked 14 hours; Movement — None recorded. How long units stay parked is a specification question, not an afterthought.
- At handover. Use location history and the relevant condition records to support the conversation about the unit and its journey. Written example: Journey record — Loading to delivery, 11 hours; Door events — 2 recorded, with times; Followed up by — Named depot owner. A door opening may be an expected delivery. A movement may be a planned transfer. Operational context decides.
Read the signals together
| Signal | What it helps you check |
|---|---|
| GPS location | Where the connected unit is reporting from. |
| Door event | When and where a fitted door sensor recorded an opening. |
| Unexpected movement | A movement event to compare with your operating plan. |
| Temperature and humidity | Conditions at the installed measurement points. |
Give the team enough operational context to interpret events, with a consistent unit identity and a named person to follow up.
Specify the installation for its time away from the truck
Tell us how long units stay parked, whether they move between operators and where they travel. We assess mounting, independent power, environmental conditions, connectivity and sensor placement before selecting equipment.
Not every asset needs every sensor. A dry container, an unhitched trailer and a temperature-sensitive load can require different configurations. The scope should follow the information you actually need at each handover.
Installation includes checking that the selected device and sensors report correctly. We configure users, expected movement and alert thresholds, and discuss reporting and retention before routine use.
Tell us about the units
Four answers are enough for a realistic proposal.
- How many trailers or containers you manage
- Where they operate, including cross-border routes
- How long they remain independent of a truck
- Which events or conditions matter to the cargo
What it monitors
What you can see and control
GPS location
Real-time position of each trailer or container.
Door-open alerts
Know when a door is opened, and where.
Temperature
Track the conditions inside the unit.
Humidity
Spot conditions that can damage cargo.
Unauthorised movement
Alerts when a unit moves when it should not.
Why it matters
What it changes day to day
- Find unhitched trailers and parked containers quickly.
- Detect tampering and theft sooner.
- Show customers the conditions their cargo travelled in.
Who it is for
Typical users
- Freight and haulage
- Container and depot operators
- Cross-border logistics
How it works
From installation to alerts
- 01
Survey and install
We confirm what you need to monitor, fit the devices and check each one reports correctly before handover.
- 02
Connect
Devices send data to the cloud platform. You get user accounts, alert rules and the thresholds that matter to you.
- 03
Monitor and act
Watch live status on the web or mobile app, get alerts when something moves out of range, and review history when you need it.
Questions
Answered directly
Can we track a trailer that is not attached to a truck?
Yes. The tracker is on the trailer or container itself, so it reports whether or not a truck is attached.
Can this monitor temperature as well as location?
Yes. Temperature and humidity readings are recorded alongside location. For refrigerated trucks, see cold-chain temperature monitoring.
