Vulcan On-Board Scales designs and manufactures specific on-board weighing solutions for high capacity dump trucks, articulated dump trucks, and specialty hauling vehicles and equipment.
On-board scales give the driver the ability to monitor the payload weight accumulated during the loading process. This allows control of the haulage weight, minimizing liability issues while promoting hauling efficiency and reinforcing positive driving habits. Managers have the option of setting operational weight limits. The driver can then act on the set weight limit using continual real-time feedback from the in-cab meter. The meter has payload warning options letting the loader know when a capacity target is reached. It is the most basic weight management / monitoring system.
Other forms of information derived from the basic weight data include: number of loads hauled per shift, tons hauled per shift, time between loading and dumping, and carry back weight. All data is stored and can be sent to external computing devices. This information is useful in creating vehicle service strategies and determining overall vehicle service lifetime. The Vulcan On-Board Scale system is a simple and effective entry point for companies looking for a way to monitor and control how much any single vehicle or fleet is hauling to maximize efficiency and vehicle uptime while minimizing safety and liability issues.
HOW THE SYSTEM WORK
The basic measurement components of the weigh system are the chassis mounted load cells and the rear hinge pin load cells. As payload is added to the dump body, the weight is transferred to the truck frame chassis through the load cells and rear load sensing hinge pins. These components measure the weight and send the weight value as an electrical signal to be displayed by the meter in the cab of the vehicle.
