The facts speak for themselves:
SDI builds a better side dump trailer.

And as a smart business owner, your common sense will prevail as you make your important choice about which side dump trailer will best help your business' success:

Fact: Loads release faster from a straight side and better dump angle. SDI has a 50° dump angle...the most of any side dump trailer manufactured.

Fact: 50° dump angle means less material sticking in the tub. SDI's dump angle assures your load will come out quicker, with a cleaner tub.

Fact: The strongest points on a trailer frame are where the frame is supported...not in the middle. SDI's design and tub material means a lighter frame and the ability to use the suspension you prefer...all while maintaining its stability.

Fact: Bolted parts are easier and less expensive to maintain, adjust and replace than welded parts. SDI's unique bolted construction means you can repair a part in the field instead of taking the trailer to a shop. There's no welding, grinding or painting required.

Fact: A lower center of gravity means better stability on the road or on the job. SDI has the lowest center of gravity available on the market.

Fact: Synthetic grease-filled hubs extend the bearing life and virtually eliminates wheel seal failure and down time. These hub caps protect your spindles and bearings from debris and damage on the job.

Fact: A side dump's tub must be strong, yet flexible enough to allow for bending and twisting without cracking. SDI's tubs are exclusively constructed of super tough, yet malleable Domex-100 Steel for more durability and longer life.

Fact: Single stage cylinders cost less to maintain or replace than telescopic cylinders. SDI's cylinders on the end of the body can be greased and maintained easily...in the shop or the field.
