While tag and sliding axle trailers are popular with many contractors, there are issues with equipment that has a high cg. "With a tag trailer, you are loading above the tires," says Odegaard. "So you are probably starting out at 3 ft. high."

This is where the detachable gooseneck trailer really shines, since it lowers equipment to the ground. But some contractors are also discovering the benefits of combining the low cg of a detachable gooseneck with low load angles.

For example, about five years ago, Eager Beaver introduced a detachable trailer initially earmarked for paving equipment. It had a much lower approach angle in the front. "We are selling a good number of those trailers, and not just to the paving industry," says McClure. They are being used to haul multiple equipment, including excavators and graders that can climb the steeper angles of a regular trailer. "They find it is just much nicer to load on these lower profile trailers."
