Different sizes and varieties of Dump Trailers | Construction Pro Tips

What size is best?

When purchasing a trailer, you need to check out the towing limits of the vehicle you plan on hauling it with. Also, make sure your receiver and ball mount match those same limits. They often don’t, surprisingly.

Deckover

Because the body and bed on a deckover trailer sits on top of the wheels instead of between them, the beds can be built wider. Also, loading pallets onto a deckover trailer that is equipped with side gates is much easier because the fenders don’t get in the way.

Totally tubular

When it comes to the frame of your trailer there are three different configurations to choose from: channel, I-beam, and tubular. Different manufactures use different types. Here are the pros and cons:

Galvanized Trailers | Construction Pro Tips

5 / 30

Finishes

Galvanizing a trailer is one way to go above and beyond a normal paint job. Galvanizing is a process where the trailer is submerged in rust resistant chemical bath. Total submersion ensures that the chemical coats the inside of the tube frames and gets into all the other nooks and crannies. Galvanizing is not cheap, but it will increase the life-span of a trailer and definitely increases resale value.

A scissor lift | Construction Pro Tips

Lifting Mechanism

There are a hand-full of different lifting mechanisms to choose from. You can get a telescopic-style hydraulic lift (usually mounted on the center front of the box) that will lift the box all the way to its dumping angle with just one cylinder. Or you can go with a dual-piston style that uses two pistons under the trailer to push the trailer up to its dumping angle.

Side wall options

Wall heights are an important thing to consider when buying a trailer. Most trailers have a standard 24-in. wall height, but if that’s not enough you can order or even build your own extensions.

Trailer Metal Thickness | Construction Pro Tips

8 / 30

How thick should the metal be?

When deciding on which trailer to buy you can’t forget about metal thickness. Some manufacturers build trailers with thicker metal than others. The metal on the bed of the trailer is always thicker than the sides because the bed takes more abuse. If your trailer will never see anything other than mulch you shouldn’t be too concerned about the bed thickness. But if you plan on filling your trailer with boulders and concrete rubble a bed with thicker metal is the way to go. Just remember that steel is heavy so the thicker the metal, the heavier the trailer. The heavier the trailer, the less weight it can accommodate.

Axle Options

If you know that you are going to need to be able to handle more weight you can typically option to go to a larger axle. Usually larger axles require heavier duty wheels, thicker and more studs for the wheels, and larger brakes. The two main options are torsion axles and leaf spring axles.

Rear Gates

Here are the most common rear gate options:

Red Side Gates | Construction Pro Tips

11 / 30

Side gates

Without side gates, pallets need to be loaded into the back and pushed in to one another, and unloading them is even more difficult. Side gates make loading and unloading pallets a breeze and allow loads to be spaced evenly in the bed. Side gates also create easy access for tying down heavy equipment and machinery.

Ramps up into the trailer bed | Construction Pro Tips

12 / 30

Ramps

Most ramps are stored underneath the bed near the back of the trailer, but there are companies hanging them on the side of the box. Ramps are heavy and the ones stored underneath are typically easier to wrangle into place. There are also ramps available that are built right into the tailgate which, if you plan on loading your dump with equipment on a regular basis, could be a good option . Want to get really fancy? Spring for a hydraulic assisted ramp/tailgate that can be lowered into position with just the pull of a lever.

Aluminum trailer wheels | Construction Pro Tips

13 / 30

Wheel options

Just because it works hard doesn't mean it can't look good. These aluminum wheels look great and they won't rust. But keep in mind that some aluminum wheels are limited in the weight they can handle. Monstrously heavy rigs may only have the option of solid steel wheels, which can support a much heavier load.

Tires spec chart | Construction Pro Tips

14 / 30

Tires

Tires need to be sized for your trailer.  Be especially aware of this when shopping for a used trailer. Undersized tires are a safety hazard. There are a lot of things you can save money on when buying your trailer, but you should never skimp on your tires.

A spare tire holder | Construction Pro Tips

15 / 30

Spare tire holder

The most common location for a spare tire is the side or front of the box. Some manufacturers hide the spare under the bed, but this might not be the best option for those of you who live in a state where they use  road salt to combat the harsh winters. 

Stripped down brake | Construction Pro Tips

16 / 30

What's to know about brakes?

Brakes are your best friends when hauling 20,000 pounds down the highway. Brakes are usually sized with the axle so there isn’t always an option for an upgrade. Some manufacturers do offer disc brake upgrades.

Solar panel charging option | Construction Pro Tips

17 / 30

Charging options

The hydraulic pump that powers the lift rams is almost always powered by an on-board battery. And of course the battery needs to be charged on a regular basis. Here are your charging options:

Couplers: Adjustable and Pintle | Construction Pro Tips

18 / 30

Couplers

The two most common ways to hook up a heavy (non 5th wheel) trailer are either a ball mount or a pintle. Either way, an adjustable tongue is a great option because not all trucks are the same height. To haul a trailer safely it should ride close to level. Pulling a trailer out of balance is dangerous, is hard on the truck, and causes uneven wear on the tires.

A pneumatic jack | Construction Pro Tips

19 / 30

Pneumatic versus manual jack

If you know you’re going to be hooking up and dropping a trailer all the time, you should consider purchasing a hydraulic jack. Sure, cranking a manual jack doesn’t take that much energy, but the hydraulic option is faster, and who doesn’t like watching stuff go up and down hydraulically?

Trailer tool box | Construction Pro Tips

20 / 30

Tool boxes

There are two types of toolboxes, steel and plastic. Plastic boxes are great because they don’t rust. Steel boxes look nice when they’re new, but they rust. Be sure to get some sort of storage on your trailer.

Tiedown Options | Construction Pro Tips

21 / 30

Tie downs

When hauling equipment, keeping your load secure is critical. Every trailer should have tie down anchors. Anchors on the side of the bed (instead of the floor) are nice because a broom or shovel won’t snag on them and material and debris won’t get hung up on them as easily when dumping.

Trailer Tarp Cover | Construction Pro Tips

22 / 30

Roll tarps

Covering a load is your duty to the other drivers on the road, and a roll tarp makes covering a load easy. Using a regular tarp only takes 10 minutes, but after a while those minutes add up.

Trailer Drop Legs | Construction Pro Tips

23 / 30

Drop legs are a safety essential

Drop legs are an option that often gets overlooked. It’s not because they're expensive; they aren’t. It's because people don’t realize they need them until they load their first piece of heavy equipment and the tongue of the trailer pops up off the ground, taking the back of the truck with it. Or worse, the tongue comes loose and slams into the back of the truck causing thousands of dollars worth of damage. Drop legs keep the trailer nice and stable the entire time you're parked.

A wireless remote | Construction Pro Tips

24 / 30

Remote

A wired remote is standard on most trailer, but wireless remotes are new in the world of dump trailers. The great thing about wireless remotes is they let you keep an eye on the load while you drop it without having to run back and forth from your cab to the back of the trailer.

Mudflaps | Construction Pro Tips

25 / 30

Mud flaps

Adding mud flaps to your trailer is a no-brainer. They protect the paint on the trailer and the other drivers on the road.

Chain holders under trailer arm | Construction Pro Tips

26 / 30

Chain holder

Having a spot to hook chains on your trailer is a nice option. Without a chain holder, the chains usually get laid over the tongue, which can chip the paint.

27 / 30

Fork holders

If you have forks, these fork holders are a must-have. Being able to carry forks on the side of the trailer frees up a lot of space in the bed.

Trailer Customization | Construction Pro Tips

28 / 30

Customization

If you have an idea for a customization it never hurts to ask.  Many manufactures will fabricate custom accessories like built-in pockets to store shovels or rebar. There are also a ton of great products to help you get the most out of your trailer.

5 Year Warranty | Construction Pro Tips

29 / 30

Warranty

A dump trailers is a relatively simple machine and is normally built like tank. But dump trailers are not cheap either, and if something does go wrong, you want the manufacturer to stand behind their product. Don't assume a "5-year warranty” will cover everything for five years. Check to see what’s actually covered in those five years and if anything is prorated, and compare that to other trailer brands you're considering.
