An Inside Look at On-board Weighing Systems
There are certain instances in mining operations where weighing loads from a designated weighing site is purely inefficient. This is when on-board weighing systems come into play.
On-board weighing systems are some of the most simple, accurate, easy-to-install, and universally-applicable weighing systems for haul trucks and other load-bearing equipment.
What Are On-board Weighing Systems?
On-board scales are weighing systems that are integrated to the vehicles, trucks or equipment and measure the weight of their in-bound loads without needing external weighing systems. In trucks for instance, they’re seamlessly installed onto the trucks’ chassis with interface provided in the driver’s cab.
How Do On-board Weighing Systems Work?
They work using mounting sensors, which are installed in-between the chassis and axle of the trucks, vehicles or equipment. In vehicles, the load sensor mechanism measures the spring deflection once you load the vehicle, from which on-board load weight measurements are derived instantly. This is usually measured through electronic burden cells, applying strain gauge technology onto the overall vehicle scale system. The temperature of the cells is repaid and requires minimum maintenance.
The digital read-out display fitted inside the vehicle’s cabin allows for easy recording and assessment of the weight metrics. In most systems, the display takes the form of a huge LCD screen with illuminated digits.
Applications of On-board Weighing Systems
What purpose do on-board weighing systems serve in helping various businesses and industries determine the weight of heavy-duty loads on different pieces of equipment?
Conveyor belt on-board weighing systems are suitable for stationary applications such as in mining operations or warehouses. Multiple scales can be monitored from one controller, which minimizes error and supervisory overhead.
On-board forklift weighing systems are usually smaller than other scales, but offer increased productivity and improved safety in high-paced environments. They allow operators to load vehicles correctly and to check the available stock against predetermined benchmarks or pallet weights pre-programmed onto the on-board weigh systems.
There are certain on-board weigh systems which are so sophisticated that they are used in grain carts, loaders and combines to track weight as well as to record moisture content, grain yield, harvest rate and speed of collection.
On-board rail car weigh systems are designed to aid assign value to loads being transported on railroad cars. They are often installed onto the main lines of rail tracks, and not necessarily onto rail cars themselves.
Haul Trucks & Dump Trucks
On board weighing systems fitted on dump trucks and haul trucks are common option for ag weighing. They can be fitted on various types of load bearing trucks, which makes them very versatile.
Pfreundt On-board Systems for Mining
Pfreundt, a German-based manufacturer and engineer behind some of the most revolutionary on-board weighing technology, is a leading brand in the mining industry. Pfreundt on-board scales can be integrated various forms of heavy-duty vehicles and equipment providing weight data of the loads being carried.
In North America, there are various suppliers of on-board weighing systems. One of the most reputable suppliers of Pfreundt on-board weighing systems is Walz Scale.
