4.4. Effect of Steepness of Grade

So, sometimes your machines may have to work on a very steep terrain. So the slope may be very steep. So, your machine has to climb the particular slope and work. So, in that case, as I told you earlier, we have to go for a machine with a greater horsepower capacity, because the machine has to overcome the particular grade resistance and then only you can do the actual job.

When working on steep terrains, the machine must exert additional force to climb the slope. This additional force is referred to as grade resistance. To effectively manage this, a machine with a higher horsepower is required. Horsepower denotes the machine's ability to perform work, and greater horsepower means the machine can easily climb steep slopes while still being able to perform its designated tasks. If you select a machine without sufficient horsepower, it may not be able to perform effectively on a steep incline.

Think of riding a bicycle up a hill. If you're attempting to climb a steep hill on a bicycle that has low gears or is not designed for tough climbs, you might find it very difficult and exhausting. However, if you have a bicycle specifically designed for mountain biking, with more powerful gears, it would be much easier to climb that steep hill. Similarly, construction machines need the right horsepower to tackle steep grades.

So the steep grades demand greater horsepower machines and on steep grades, we have to go for tandem power machines. So what are tandem power machines? Basically there are some special machines where all the axles are powered all the axles of the machine will be powered.

Tandem power machines have multiple powered axles, meaning that instead of just one axle providing the necessary traction to move the machine, multiple axles work together to share the load. This is particularly useful in steep terrains where grip and power to overcome gravity are crucial. Tandem power machines can significantly enhance productivity by ensuring that all wheels have traction and are working efficiently, even on inclines.

Imagine trying to push a heavy cart up a steep path. If only one person is pushing, it could be very difficult to get it moving. However, if five people are pushing together, the cart can move much more easily. Tandem power machines function similarly by distributing the work across multiple power sources, allowing them to handle tough conditions effectively.

So, particularly for tough conditions like this, like steep terrain or poor underfoot conditions, if you go for tandem power machines, you can have a very high productivity. So though the cost of this machines may be higher, but the production it will result in a higher productivity. So, your total project cost gets reduced.

Investing in specialized machines such as tandem power machines, although initially more expensive, often leads to better productivity in the long run. Higher productivity means tasks are completed faster and potentially with fewer machines, thus reducing overall project costs. This economic consideration is critical; when selecting machinery, it is vital to evaluate not just the purchase price, but also the machine's efficiency and the savings it generates during operations.

Consider a high-performance laptop versus a basic one. The high-performance laptop might cost more initially but allows you to work faster and complete tasks more efficiently. Over time, it can save you hours of time, making it more cost-effective than the cheaper option. In construction, spending more on efficient machinery can lead to completing projects quicker and at a lower total cost.

So, this graph shows you a typical performance chart. So, equipment manufacturer will provide these kinds of performance charts for every model of the machine produced by him. So, by looking into this performance chart, you can get an information on what will be the speed of the machine for a given project condition say for this particular underfoot condition.

Performance charts are invaluable tools provided by equipment manufacturers. They detail how a machine performs under various conditions, including different grades, soil types, and other factors. By referencing these charts, engineers can predict how fast a machine will operate in specific environments, enabling them to select the most appropriate equipment for their project needs.

Think of a performance chart like a user manual for a smartphone. It gives you an overview of what the device can do under different conditions – such as whether you can play games smoothly or if the battery lasts long during video calls. Similarly, performance charts help determine the suitability of construction machinery for different tasks.
