4.2.2. When Trucks are Greater Than the Balanced Number

But the loading time will be number of bucket loads multiplied by the bucket cycle time. ... So, only that capacity your machine can take because the structural frame of the machine is designed to handle that particular load only.

In construction and heavy machinery operation, understanding gravimetric capacity is crucial. This capacity refers to the maximum weight that a machine can safely handle, as provided by the manufacturer. It's fundamental to adhere to this limit to avoid damaging the machine. Overloading can lead to structural issues, excessive wear, and reduce the machine's lifespan. Therefore, consistently checking the load weight against the gravimetric capacity is essential.

Imagine a weightlifter who can only safely lift a certain amount of weight without risking injury. If they try to lift beyond their capacity, it can lead to serious injury. Similarly, heavy machinery has limits, and exceeding these can cause costly damage.

So, since the density of material can vary from case to case, it is always advisable to check whether the load weight is within the safe gravimetric capacity. ... if you keep on overloading your truck it will result in premature aging of the truck.

When trucks are overloaded, especially with denser materials such as wet sand, the risk of damage increases significantly. This can lead to higher operational costs due to more frequent tire replacements and repairs. It's essential to regularly verify the weight of the load to ensure it doesn't exceed the truck's rated gravimetric capacity to avoid these issues.

Consider a car overloaded with passengers and luggage. If the car is pushed beyond its designed carrying capacity, it could face tire blowouts or even engine problems, which illustrates the importance of adhering to weight limits.

Now let us see how to balance the interdependent machines, trucks and the excavators. ... So, balancing the capacity of the hauling equipment and the excavator bucket size will result in maximum loading efficiency, and reduce total cost.

Balancing the number of trucks and excavators is essential in construction operations to maximize productivity. Ideally, the truck capacity should be 4 to 5 times the capacity of the excavator bucket. This balance ensures that the loading and hauling operations are synchronized, reducing downtime and optimizing work processes.

Think of a relay race where each runner must pass a baton to the next at just the right moment. If one runner is too fast or too slow, it causes delays and inefficiencies. Similarly, in construction, ensuring that trucks and excavators are balanced is crucial for smooth operations.

So, that depends upon the cycle time of your truck and the cycle time of your excavator. So, divide the truck cycle time by the excavator cycle time, you will get the balance number of trucks.

The balanced number of trucks is determined by comparing the cycle times of the trucks and excavators. This involves calculating the cycle time of the truck (which includes loading, hauling, and dumping) and dividing it by the cycle time of the excavator. This calculation helps in determining how many trucks are adequately required to maintain efficient operations without causing delays.

Imagine a bus schedule where buses need to arrive at regular intervals. If one bus takes longer to complete its route, it affects the timing of the next bus. By understanding and calculating these times, we ensure that the buses (or in this case, trucks) arrive and depart efficiently.

So, the number of trucks are greater than the balance number, so the trucks will have the idle time, truck will be waiting for the loader, loader will be critical here.

When the number of trucks exceeds the balanced number, the trucks will sit idle, waiting for the loader to become available. This situation can lead to wastage of resources as trucks are not being utilized effectively. In scenarios where trucks are in excess, the loader's cycle time becomes the limiting factor for productivity, making it essential to find the right balance.

Think of a classroom filled with too many students for the number of teachers available. If there are more students than teachers, many students may not receive the immediate attention they need, leading to inefficiencies in learning.

But very commonly you can see that people prefer to round it to lower than balanced number... That is why people always prefer rounding it to lower number, but the logical way is to work out the economics of both the cases and then take a decision.

In practice, many operators opt to round down the number of required trucks below the calculated balance number to reduce the risk of over-utilizing machinery, especially loaders. This precaution helps in maintaining equipment faster and prolongs its operational life. However, the decision should be economically driven by analyzing costs associated with both options.

When planning a party, one might round down the number of guests to avoid overcrowding. While having fewer people might be safer and more manageable, budgeting for the food and drinks should also consider whether it meets the expected attendance to avoid waste.
