Bulldozer Lifespan [ When To Plan Your Replacement ]


If you’re planning on embarking on any construction project, it would be wise to get familiarized with the machinery. It does depend on whether you are purchasing the bulldozer or using it for a particular action; nonetheless, in this article, we are giving you clarity.

Bulldozers, like excavators, require extra care for their undercarriage, which supports the machine and is open to its operational conditions. Most contractors expect their bulldozers to last seven to ten years on average.

To better understand the running time of a bulldozer, we must comprehend the definition and purpose of this machinery.

What’s A Bulldozer?

A bulldozer, also known as a dozer, is a powerful machine used in road building, farming, construction, and wrecking. It comprises a large, broad steel blade or plate attached to the front of a tractor.

A bulldozer is a large, motorized machine with continuous tracks or massive tires. This construction or conversion machine has a metal blade for pushing material, such as soil, sand, snow, rubble, and rock.

When determining the lifespan of a bulldozer, it is imperative to understand whether you are purchasing one or just want to know the time it will take to complete specific tasks, so let’s dive in.

Purchasing a Bulldozer

When and if the time comes in which you are considering purchasing a bulldozer, it is essential you understand how to operate and maintain it.

You must make sure the dozer’s undercarriage is suitable for the type of work you will be doing with it. For example, transporting soil across level ground won’t place nearly as much strain on the undercarriage as managing heavy or abrasive materials in a landfill, crawling over various items, or traversing rugged terrain.

There’s a rationale for the distinction between regular and heavy-duty undercarriages. Minimizing damage to the undercarriage can also be done by following good handling and best practices for operating, such as limiting reversing.

This will have an impact on the life cycle of your bulldozer. That’s why we encourage the complete understanding of these.

The components of a dozer’s undercarriage are designed to wear out simultaneously after 4,000 hours or half the engine’s service life. At 2,000 hours, it’s time for a midlife tune-up.

Repair costs climb as a machine becomes older. Therefore, equipment managers try to extend component life to keep the unit’s costs down. 

Timelapse Per Task

We must understand that there are different intentions for the usage of bulldozers, which will also lead to different periods to complete specific tasks;

For use in fields, plains, and locations with uneven terrain. You can do a simple project in one week; this is crucial to consider because not all contractors are interested in acquiring the machine; if leasing is an option, this is the machine for you!

According to the developer, it would take two months to clear land, chop down trees, and prepare a job site for a 300-home construction.

Surface mining, cleanup, stockpiles, road maintenance, reclamation, and regular operations requiring transit between numerous sites are just a few of the uses for these exceptional utility machines.

This form of labor will take a varying amount of time depending on the size of the construction project; for example, if the land is broader, the operation will take longer.

Replacing A Bulldozer: What To Be On The Lookout For?

Whether you’re leasing or purchasing a bulldozer, maintenance is a crucial part of the lifespan that could be obtained from these machines. Here’s what you should be paying attention to:

Diagnostic 

First of all, you must ensure before getting the equipment that you have prepared staff that could diligently notify and verify any mishap that might arise from the machine’s operation.

Inspecting wear-prone elements, such as cutting edges, and repairing them as needed, will help the blade last longer and work more efficiently.

In addition to this, we can avoid premature deterioration by inspecting blade attachment joints to ensure they are correctly shimmed and lubricated.

Undercarriage

Construction masters have labeled the undercarriage as the most critical aspect of the machinery.

The importance being because the undercarriage of a dozer accounts for roughly 20% of the machine’s purchase price and up to 50% or more of the machine’s lifetime repair costs; appropriate maintenance is essential for equipment owners who want to get the most out of their investment.

Daily inspections of the hardware throughout the undercarriage are recommended. Operators should inspect the undercarriage for excessive debris and keep an eye on the sprocket teeth for symptoms of extreme wear.

Since we’re talking about how long it takes to perform things in this post, it’s a good idea to emphasize that a comprehensive inspection of the undercarriage should take place between 500 and 1,000 hours.

Hydraulics

Just like the majority of heavy types of equipment, bulldozers have complex hydraulic systems. It is leading to an imperative need for it to be a priority at the time of maintenance.

The suggested practice is to look for scratches, dents, or leaky seals on the hydraulic cylinders. Leaks will eventually develop from scratches on the chrome of hydraulic cylinder rods.

Depending on the application, it is critical to keep the area surrounding the cylinder rods clean so that material does not pass through the seals and pollute the hydraulic system.

Hours On The Bulldozer

The hour review of the bulldozer is particularly crucial for buyers looking at second-hand machines. Before you sign the contract, be sure you know how many hours remain on the bulldozer’s clock. A bulldozer with around 5,000 hours on it can still be highly useful.

Nevertheless, you must first examine whether the engine and undercarriage have been changed before purchasing it. Buying old equipment can be a smart alternative if the bulldozer has been well maintained.

Avoid dealing with less reputable companies that have been known to change the clocks on older models.

When Do I Need To Replace My Bulldozer?

When the time comes for your bulldozer to be replaced, it’s safe to say you will know right away since you’ll be the first to notice if you could no longer fulfill the intended use for the machinery. 

You will also consider the possibility of replacing it once all of the maintenance has been confirmed. This will include possible part replacements and hardware troubleshooting.

Nevertheless, the primary component that you should be looking at when contemplating a bulldozer replacement is SECURITY!

When purchasing a bulldozer, safety is paramount, primarily if it will be used for construction. Ensure everything is up-to-date in terms of security. In addition to this, make sure the instructions for using your new dozer are clear and current.

If you’re thinking about buying a used bulldozer, be sure there haven’t been any off-the-books modifications that could compromise its utility or safety.

Educate yourself and your team if needed in all of the safety gear before operating the machine.

Conclusion

To sum everything up, you have to dive deep into bulldozer waters before you can fully grasp what it is like to own one.

You also need to have the right team or prepare yourself accordingly for high-demand regular maintenance sessions. This is crucial since you don’t want to devalue your investment. Ultimately, you want to get the best out of your machinery.

Whether or not you purchase one of these heavy-duty machines, the same applies to leasing or renting one of them. After a job or simply in general use, it is just as important to note how the machine is behaving.

It doesn’t take a master’s degree in construction to get a thorough understanding of the functionality of this machine. Keep up with security measures and make maintenance a regular practice.

You will be able to determine quickly when the equipment is damaged to the point of replacement and when to have a professional support team look at it.
