Automatic random weighing refers to an automatic selection method for measuring the weight of transported material, involving equipment such as trucks, excavators or wheel loaders, without the need for manual intervention. Through more effective data that is closer to the real situation on site, productivity can be assessed more clearly. The system randomly determines which equipment should be weighed each shift, avoiding operational losses and sampling bias.

The method of weighing ores on road scales is a crucial practice for guaranteeing the accuracy of the amount of material being transported, stored and subsequently processed. This information is essential for managing the amount of material being moved and optimizing productivity.
Exploring the advantages of automatic random weighing paves the way for more effective and economical logistics management, optimizing processes and reducing costs. Check out some of the main benefits:
Trucks are weighed using road scales on a sample basis, so that only a portion of the total number of trips made in each shift is weighed each day.
The random weighing method by the weighmaster (the person responsible for weighing the trucks on the road scales) is where the weighmaster himself randomly selects which truck should pass through the scales to check the load, i.e. there is human intervention in the weighing and collection of data for productivity analysis. This data may not accurately reflect actual daily production, as human bias can influence the choice of truck selected for weighing, resulting in a higher or lower average load than the real one.
In automatic random weighing, on the other hand, there is a system that randomly selects which trucks will be weighed by the road scale from a pre-defined weighing plan. The automation of this process makes it possible to have an accurate average load in real time and a high degree of assertiveness in assessing productivity and controlling the production plan.
For assertive management of the average load of the transport fleet, Mining Control offers random weighing functionality. Through the system, it is possible to create weighing plans targeted by fleet, shift and material, guaranteeing unbiased, automated sampling and the reliability of the reported mass.
By adopting Mining Control’s weighing module, it is possible to manage cargo and transport fleets more effectively, with more assertive average load control, resulting in increased productivity and reduced operating costs.
