Since they came into existence in the early 1900s, dump trucks, with their deep open beds carrying huge material containers, have been a source of fascination and curiosity. The sheer size of these heavy-duty machines, plying up and down streets, picking up trash, and stoking the imagination of every child in the neighborhood is a nostalgic memory that many carry well into their adulthood.
The real-life application of these engineering marvels is no less awe-inspiring either. Dump trucks (or dumping trucks, dump trailer, dumper trailer, dump lorry, or dumper lorry, as they are also called) have a direct responsibility in maintaining health and sanitation in modern, urban society by collecting and hauling away household trash. They keep industry moving by transporting huge volumes of waste material generated by demolition, construction, mining, excavation, and other commercial jobs sites to central dumps and landfills. They provide employment to well over 100,000 employees in the waste management sector, and according to research findings organized by Hexa, the dump truck service market is slated to expand yet more by 2025, and reach a whopping $ 20.64 billion!
Dump trucks come in a variety of shapes, sizes, and price ranges, so it is important to know what you need before making a purchase that will greatly impact the growth and expansion of your business. To help you find the dump truck that best suits your budget and performance expectations, therefore, we've compiled the most relevant information in a quick explainer sheet below:
CHOOSING THE RIGHT DUMP TRUCK
GUIDE TO HELP YOU CHOOSE
1. Dump Truck: Bodies
There are 3 body styles available for dump trucks with each being better suited than the others for particular applications: traditional rectangle, half round and semi-elliptical.
When you need more space on the bed, a dump truck body that is shaped in the old-fashioned rectangle will offer you the most room. This style is popular because of its sheer strength and low center gravity when carrying heavy loads. Another thing you can get with traditional rectangular bodies is a double-wall to keep any visible damage to the inner body hidden inside a pristine, outside one.
When it comes to performance under impact, the half-round dump body style scores because of its semi-circular shape. Not needing supporting cross members means the units also save on overall weight which can then be used to proportionally increase payload capacity. A third advantage of its shape that can be very useful when hauling certain kinds of waste is that sticky materials don’t adhere so easily on the floor, making clean-ups a whole lot easier.
That said, the absence of a flat, roomy floor space means the half-round won’t be the right choice to transport goods like pallets or heavy equipment that need level ground space.
The semi-elliptical dump truck body is often referred to as a bathtub or a tub dump and it combines certain intrinsic features of both the dump bodies described above. The floors are like that of the rectangle but their haul shape mimics the half-round.
Like the half-round, the semi-elliptical dump body also does not use crossmembers and therefore, can absorb the force of impacts throughout the body.
2. Dump Truck: Body Metals
When it comes to dump trucks, there are two different metals to consider: steel and aluminum. Which metal you finally choose depends on what type of tasks you need to use the dump truck for and attributes (such as weight) of the loads it will be expected to carry.
Steel has traditionally been the metal of choice, making transport of hard, angular and abrasive materials like asphalt, concrete and gravel less likely to cause damage.
When it comes to upfront costs, they’re also more economical. Aluminum may save money over time, but the financial outlay for the initial purchase is significantly higher.
That said, it seems like every industry is making a shift towards lighter materials these days. The trucking world hasn't been an exception and over recent years we've seen this trend grow even stronger with more companies moving away from heavy steel.
Pure aluminum (which offers less than half the strength of steel) is fortified with alloys like chromium, copper, titanium and zinc to make them worthy for truck bed construction.
Annual maintenance costs are much lower than steel because there are no risks of rust and corrosion breaches. Lighter body weight means increased payload capacity and less fuel expenditure. And then there are better resale value propositions and longer warranties. An environmental advantage would be that aluminum produces less greenhouse gas than steel.
3. Dump Truck: Engines
The purchase of a dump truck is an expensive decision. The wrong engine could make your finances go up in smoke before you’ve even started making money by wasting fuel and time on difficult terrain.
Matching engine power to jobs at hand is the most prudent way to approach the decision to purchase a truck engine that can range between 300 and 600 HP. If payloads are light, for example, and the roads are reasonably flat with no steep inclines and grades, you will need less horsepower.
4. Dump Truck: Transmission
The availability of gear options usually makes manual transmission the go-to choice for dump trucks. A low gear for instance, improves the vehicle’s maneuverability on shifty soil while multiple reverse speeds help backing up over significant distances.
Automatic transmission does not offer such possibilities of nuanced driving, but the lack of clutch and gears cause less exertion while driving and reduce fatigue (and risks of an accident!) during long-haul jobs.
Integrated automated manual transmission is yet another choice that is fast gaining in popularity because the driving experience is more comfortable and fuel consumption is optimal as well.
5. Dump Truck: Axles
Federal laws have put something called GVWR (Gross Vehicle Weight Rating) in place to safeguard against excessive wear and tear on roadways and bridges that can be caused by the constant flow of overweight commercial traffic. The GVWR accounts for the collective weight of the dump truck’s body, chassis, engine, fuel, driver, and of course the payload.
GVWR is governed by the number of axles on a truck. Fewer axles means the dump truck can carry less weight to be compliant with GVWR regulations that are becoming more and more stringent every year. A Super Dump, on the other hand, with 4-7 axles, can haul 19-26 tons of payload and still be compliant.
Make sure to check with your state's Department of Transportation for any laws regulating weights and axles on vehicles before purchasing.
When buying a dump truck that will give you years and years of service and be a foundational resource in the success of your business, price isn’t the only important factor when choosing a dealership.
The dealer has a very important role in determining what kind of experience it will be for your purchase – from looking at specs and deciding which truck is going to be the best match for you to offering financing options if needed.
Prepare a lot of questions in advance of your first visit to the dealership. You almost certainly will not remember to ask all pertinent questions at the time if you don’t do this bit of homework first.
Explain all your needs, such as the kind of jobs you expect to do and the payloads you expect to carry, so the dealer has enough information to guide you to the most suitable purchase for both cost and performance.
If the dealer doesn’t seem invested in helping to make the right choice, we always suggest you shop elsewhere.
Any dump truck worth its load will have a strong and durable body, capable of withstanding years of heavy use. However, even the most well-made dump trucks can succumb to wear and tear over time.
Therefore, it is important to inspect the body of the truck for any signs of damage, such as cracks, rust, or dents.
The dump box and box liner should also be inspected for any signs of wear or damage. In particular, pay attention to the dump box material. Aluminum dump boxes are lighter than their steel counterparts and can help reduce fuel costs. However, steel dump boxes are stronger and more durable, making them the better choice for hauling heavy or rough materials.
Take a look at the tires and check for visible damage and misalignments.
Frame rails provide support for the dump body and the dump truck's engine, and they're key to keeping the dump truck stable while it's carrying a load. Look for any signs of sagging or bowing, as these could be indicative of overloading or other issues. Also, check for corrosion or other signs of wear, as this can weaken the frame rails and reduce the dump truck's overall strength and stability.
Engine inspection is best left to professionals. Call in a qualified mechanic to do a thorough investigation.
Good luck!
