Understanding Off Highway Trucks
Unlock Audio Lesson
Today, we’re introducing off-highway trucks. Can anyone explain why these trucks are termed ‘off-highway’?
They’re not allowed on public roads?
Exactly! They’re designed for specific environments like construction sites and quarries. What features do you think make them suitable for those environments?
Maybe they're built to handle rough terrains?
Right! They often have robust builds and powerful engines. Let’s remember that these attributes justify their high operational costs.
What’s the average cost for one of these trucks?
Good question! For example, the initial cost can be around 3 crores. This cost allows for advanced features suitable for their tasks.
Cost Estimation Methods
Unlock Audio Lesson
Now, let’s discuss how we estimate the costs associated with these trucks. Who can name one of the methods?
Is one of them the Caterpillar method?
Yes! The Caterpillar method is one, and it focuses on ownership and operational costs. Can you recall the main components we cover in such estimations?
We look at depreciation, operating wages, and maintenance costs.
Great! Understanding these components helps break down the total cost into manageable hourly rates.
Calculating Ownership Costs
Unlock Audio Lesson
Let’s calculate the depreciation for our off-highway truck using the Caterpillar method. Who can remind us how to find depreciation?
We should use the formula: (Initial price - Tire cost) / Useful life.
Correct! With an initial price of 3 crores and a tire cost of 11 lakhs, based on a useful life of 12.5 years, what’s our depreciation?
It’s around 2.31 million per year!
Right! Now, converting that into an hourly rate gives us...
About 1445 rupees per hour?
Exactly! This is crucial for budgeting.
Operating Costs Breakdown
Unlock Audio Lesson
Let’s move to operating costs. What are some of the key components included here?
Fuel consumption and maintenance costs?
Right! The fuel cost is derived from the formula considering consumption per horsepower. Can someone break this down?
It’s 0.09 liters per horsepower per hour, right?
Yes! And if the engine is 250 horsepower, that gives...
Approximately 1462.50 rupees per hour for fuel!
Exactly! When we sum all operating costs, it’s vital to include these calculations for accurate budgeting in projects.

So you can see this problem in this problem you can estimate the cost for the dump truck. It is off highway truck, why we call it as off highway? This truck is not permitted on the public highways. It is an; heavy equipment high end equipment you can see that these trucks will be operated only in the project sites. You can also see some quarry truck. So those heavy machines are not permitted on the public highways. That is why we call it as off highway trucks.
Detailed Explanation
This piece of text defines what an off highway truck is and explains its primary usage. Off highway trucks are designed specifically for heavy-duty tasks and cannot be used on public roads, limiting their operation to construction sites and quarries. This specialized purpose means they are engineered to handle rough terrain and significant loads.
Examples & Analogies
Think of off highway trucks like specialized tools in a toolbox. Just as each tool has a particular function, these trucks are built specifically for demanding tasks that regular vehicles cannot handle. For example, just like a hammer is ideal for driving nails but not useful for cutting wood, off highway trucks are ideal for heavy construction work but do not work on city roads.

The initial cost is given so it was purchased with the deliver price of 3 crores. So you can imagine it is already high end equipment with special features like you can see it will be kind of articulate machine with any additional features are there with this dump truck that is why you can justify its cost.
Detailed Explanation
Here, the text mentions the initial purchase price of an off highway truck, which is stated to be 3 crores. This cost is reflective of its high-end features that are necessary for its operation in demanding environments. The phrase 'articulate machine' suggests that these trucks may have specific functionalities designed for maneuverability in tight spaces or uneven ground, which helps rationalize the significant investment.
Examples & Analogies
Consider the purchase of a high-end laptop versus a regular one. Just like the laptop with advanced features is pricier due to its capabilities, the off highway truck is significantly more expensive than regular vehicles because of the specialized equipment it includes to perform specific tasks.

The requirements are according to the type of the machine for which you are going to estimate. You can choose the appropriate estimation handbooks and choose the values estimated accurately. These numbers are just approximate assumptions just to show the methodology of how to estimate the economic cost.
Detailed Explanation
This segment emphasizes the importance of accurate estimation in assessing the ownership costs of off highway trucks. It highlights the use of estimation handbooks for guidance in determining the costs, characterized as approximate values to illustrate the methodology. Ownership costs might include interest rates, insurance, taxes, and depreciation, which must be carefully calculated.
Examples & Analogies
Imagine planning a budget for a new school project. You might not know the exact prices of materials, but you use old receipts to estimate costs. Similarly, when managing an off highway truck's expenses, operators rely on past data and guidelines to create an informed estimate, even if the numbers are not precise.
Operating Capacity and Conditions

The truck is expected to have an annual use of 1600 hours. So every year the truck is operating for 1600 hours. It depends upon every day how many hours it is operating and how many days it is operating in a particular year.
Detailed Explanation
Here, the text provides an expected annual operational time for the off highway truck of 1600 hours. This figure sheds light on the truck's workload, which can vary based on daily operational hours and how many days it is in use throughout the year. Understanding this time frame is crucial for calculating total costs related to ownership and operation.
Examples & Analogies
Think about how often you use your bicycle. If you ride it for an hour each day, after a year, that’s a significant amount of time! In the case of the truck, just as regular use influences bicycle wear and tear over time, knowing how many hours the truck operates annually affects its overall maintenance and estimated costs.
