Truck weight&location monitoring

"TruckCaliber" is equipped with sensor and IoT device (Also known as On-board Truck Scale) on the transport vehicle, which allows the driver to check the vehicle weight(gross, axle, payload) immediately while loading without any weighing. The manager of the transportation agency can monitor the vehicle weight, real-time tracking, vehicle status, volume and number of transportation. "TruckCaliber" provides a more efficient transportation monitoring system by confirming proper treatment of environmental substances, checking unauthorized dumping, permitted zone departure.

Case study

  • Case study #1

    On board overload prevention

    "TruckCaliber", which is installed in the vehicle of private and transport company', provides the driver to the information of gross, axle and payload weight in real time with a smartphone app. The driver can maximize the loading weight in the safety range and prevent overload in advance. In addition, driver do not have to drive far distance by truck scale to check the overload weight, thus ensuring more efficient and safer driving operation.

    Prevention of illegal dumping and route monitoring

    In the case of waste or dangerous environmental material collection and transportation vehicles, there are cases in which illegally dumping on the route to the treatment station or driving on an arbitrary route without permission to operate in order to save money. If there is accidents in water supply protection areas or downtown, it may lead to catastrophic disasters. "Truck Caliber" is installed in such collection and transport vehicles to prevent illegal dumping and to provide proper monitoring of freight weight and driving route, so that it helps to check the proper handling at the loading and unloading places as a smart invoice or waybill.
