To transport larger loads or specialised cargo, trucks require trailers. A trailer is an additional cargo-carrying unit attached to a truck. There are many types of trailers, each with different load capacities and requirements. Some of the commonly found trailer types in Indonesia include flatbed, refrigerated trailers, dry vans, and dump trailers.
Do you own or manage multiple types of trailer trucks in your fleet? Managing the operational risks of your trailer truck fleet is certainly an important consideration. Telematics can help you manage these risks, specifically through vehicle monitoring devices. Because trailer types and purposes vary, you may also need different monitoring devices. This article will help you determine which monitoring devices are most needed for your trailer truck fleet.
1. GPS Tracker
This device must be installed on each of your trailer trucks before adding other monitoring devices. Basically, a GPS tracker allows you to monitor the location of each of your vehicles in real-time. Currently, GPS tracker features have advanced. You can monitor vehicle activity by using geofencing and aggressive driving behaviour (sudden acceleration, hard braking, sharp turns, and speeding). These two features are important for monitoring productivity and safety in the use of your trailer truck.
2. Door Sensor
For enclosed trailers, both dry vans and refrigerated units, you will need to add a door sensor. This device monitors cargo door open-and-close activity. You can track the time, location, and duration of when the door is opened or closed. It helps you monitor loading and unloading activities, as well as possible deliveries outside the assigned schedule. You can also set alerts to be notified when the door is opened and/or closed, allowing you to take immediate action if the door is opened at an incorrect location.

3. Temperature Sensor
If you have a truck with a refrigerated trailer, a temperature sensor will be very useful for you. With a temperature sensor, you can ensure the temperature inside the trailer is optimal during the trip, so that the quality of the food or beverages being delivered is also maintained. To be immediately informed when the refrigerated temperature exceeds the upper or lower limits you set, you can set instant alerts.
4. Sensor Power Take-Off (PTO)
The use of mechanical devices on trucks, such as a dump trailer bed that is raised using a specific button or switch, can be monitored with a PTO sensor. This device allows you to track the time, location, and the geofence area where the PTO is activated and deactivated. This data is useful for monitoring operator and vehicle productivity as well as detecting truck misuse. You can also set alerts to be notified instantly when the PTO is turned on and/or off.
5. Camera
For more comprehensive monitoring, you can add cameras inside or pointing at the trailer. This way, you can visually monitor how the trailer is being used, the loading and unloading process, and the security of the goods inside the trailer. With Cartrack, you can install up to four cameras in one vehicle, allowing you to monitor from four different angles.
Many trailer trucks carry high-value cargo, which is why a monitoring system is essential. Telematics helps monitor your trailer truck more efficiently and ensures safety while travelling. You can add a GPS tracker and several monitoring devices to your trailer truck as needed. Choose Cartrack as the best telematics provider for your trailer truck operations.
