Today we’ll discuss gravimetric capacity, which is the maximum weight a machine can safely operate with. Can anyone tell me how this is determined?
Is it set by the manufacturer?
Exactly! And exceeding this limit can cause serious damage to the machine. Let’s remember it like this: G for Gravimetric and G for Guidelines we must follow.
What happens if we overload a truck?
Good question! Overloading can lead to wear and tear. For example, tires may flex excessively, causing increased costs.
Let’s talk about material density. Why do we need to consider this when loading a truck?
Because denser materials weigh more, right?
Exactly! For instance, wet sand can easily exceed the truck's capacity. Always check the density first!
What can happen if we don't?
If you don't check, you risk damaging the truck, which will increase operational costs significantly!
Now, why do you think overloading might be tempting for companies, but not sustainable long-term?
Because it can increase productivity at first?
You're correct! But this benefit is often short-lived. Over time, the cost of repairs and possibly replacing the truck becomes a burden.
So it's more cost-effective to stay within limits?
Yes! A sustainable approach saves money and keeps machinery in better condition for longer.
Refers to the specified weight limit of a truck as defined by the manufacturer.
Materials with higher density can quickly lead to overloading issues if not monitored correctly.
Overloading increases wear and tear, which can significantly elevate operational costs.
If a truck has a gravimetric capacity of 15 tons and is loaded with wet sand weighing 2 tons per cubic meter, monitoring the load is crucial to avoid exceeding this limit.
An operator who routinely adds extra side boards to increase volume must check the actual load weight against the truck's stated capacity to prevent overload.
If you overload and break your truck, get ready for more than just bad luck!
Imagine a truck on a busy road with too much weight. The tires creak and the truck shakes. It soon breaks down, costing the owner lost time and money.

Overloading trucks can lead to serious mechanical issues and increased operational costs due to wear and tear.
This section discusses the gravimetric capacity of machines, emphasizing the importance of not exceeding this limit to avoid damages and increased costs. It also addresses the relationship between truck load and tire costs, as well as the risks associated with loading materials of varying densities.
Overloading trucks poses significant risks, primarily due to the structural limitations set by the manufacturer, known as gravimetric capacity. Each machine has a specified weight limit, beyond which it suffers damage. This section stresses the importance of verifying that the weight of the loaded material remains within this limit, taking into account the material’s density and the machine's capacity.
For denser materials, such as wet sand, the likelihood of overloading increases, leading to detrimental effects like premature tire wear, which constitutes a substantial portion of operating costs. While short-term productivity may temporarily benefit from exceeding the designated load, the long-term consequences include severe wear and the potential for equipment replacement, which has considerable financial implications.
Additionally, this section touches on the impact of load characteristics on the efficiency and cycle timing of trucks, as well as the interaction between the hauling machines and their workload. Understanding these effects aids in optimizing operational efficiency and reducing costs.
