Purchasing a trailer is no small decision. It’s important to consider several factors so that you are not only getting a great price, but you’re also getting a great trailer for that price.
Not all side dumps are created equal. That’s why we’ve created a blog series to highlight a few key criteria you should use to evaluate which side dump trailer is right for your needs, even if it’s not a SmithCo Side Dump.
Many side dumps look similar from the outside, but inside the frame rails, it’s a different story. Make sure you’re getting the best bang for your buck by looking at the following:
Frame Cross Members
Some manufacturers cut corners to save weight and manufacturing costs by using thin-walled tubing/pipe. This might save you money in the short term, but it will cost you in the long run: thin-walled tubing or pipe will fail.
King Pin Plate
Side dump trailers exert significant forces on the king pin plate that other trailer types do not experience. SmithCo recommends a 3/8” thick king pin plate on over-the-road side dump trailers with thicker plates for off-road units. Some manufacturers use ¼” thick king pin plates, which will warp over time, causing them to fail DOT regulations.
Hoses and Electrical Connections
Watch for the following:
- Does the side dump manufacturer use DOT approved brake hoses connected to the brake cans, or are they using lower-quality Synflex tube?
- Are non-light harness electrical connections housed in weather-tight enclosures, or are they in the open to the elements?
- Does the trailer use larger diameter hydraulic hoses to ensure proper hydraulic oil flow, or smaller diameter hoses to cut costs? (Remember, the dumping speed of a side dump is dependent on oil flow gpm.)
- Think twice about trailers that have “off brand” tires. They might be cheaper now, but they won’t last as long, and you will be replacing them often.
- Be wary of manufacturers that claim you can carry the same weight on super single tires mounted on offset wheels as you can with a set of dual tires. A super single tire mounted to an offset wheel will NOT have the same capacity as a set of 22.5 or 24.5 tires in a dual configuration. Tires that exceed their capacity not only put the tire at risk, but also put the driver at risk of a DOT fine.
How the frame beams are constructed is vital. Avoid frames that are built with ¼” frame flange. While less expensive and lighter, side dumps built with ¼” flange are not strong enough to withstand the stresses a side dump frame goes through. It’s not uncommon for trailers with this type of lighter construction to suffer large-scale frame failures.
