Onboard Weighing Solution for Mining Applications
Accurate and reliable payload measurement is an important element of profitability and operating safety in bulk hauling. Whether for municipal, county, state or private operations, Vulcan on-board scale systems allow optimum, safe use of a truck’s payload capacity-both for maximizing loads and preventing overloading.
Vulcan On-Board Scales offers model specific on-board weighing solutions for high capacity (greater than 20 tons) dump and articulated dump trucks. The scales include a meter in the cab of the truck and warning options to let the loader know when the
maximum capacity has been reached.
The weight information can be used by the driver to limit loading of the vehicle in order to avoid overweight conditions or to load the vehicle to maximize payload efficiency. Avoiding overweight conditions minimizes maintenance costs and safety/liability issues.
The weight information can also be used by management to determine loading efficiency of the vehicle, carry back weight and the unused truck capacity due to under loading. Overload information can be useful in creating vehicle service strategies and determining
overall vehicle service lifetime.
How the System Works
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.

Vulcan V600 Meter - Software Version C-19 Designed for Dump Truck Loading Cycles
Software Description
Software version C-19 is a special software edition of the Vulcan V600 Meter. It has been specially created for use in the load-haul-dump-return cycle. It has been configured with output options to trigger relays, drive scoreboards and warning lights. This version will also capture information about the hauled product, date, time, weight and automatically stores this information in the meter's memory for downloading into a PC for analysis. Two records will be stored during the load-haul-dump-return cycle. There is a "load cycle" and a "dump cycle". The "load cycle" records the full load weight. The "dump cycle" records the empty or carry back weight. The product code, date and time are recorded with each load and dump cycle. Each weight record has a sequence number prefixed to it. In addition, if a Truck ID has been entered into the meter, this Truck ID will be appended to each record. Data stored in the V600 meter can be easily downloaded into a PC or laptop using any number of readily available programs. This information will be in the form of a comma separated
ASCII text file, which can then be imported into many commercial database or spreadsheet programs such as Microsoft Excel.
