Key Features and Functionality 

Your specific needs will depend on the weight and type of items you are dumping, but a quality side dump trailer has the following features:

  • Has an angle of at least 50 degrees to ensure that materials will come out faster with less sticking to the tub
  • A lighter frame that has the flexibility to change suspension without sacrificing stability
  • Parts that are bolted to the side of the side dump trailer rather than welded, for easy replacement and repair
  • Low center of gravity for optimal stability
  • Tub area and bearings should be able to be oiled quickly for easy maintenance
