The popular Mac Trailer half-round aluminum end dump trailer has been redesigned to increase capacity and improve stability.

The trailer’s payload has been increased to 60 yards as Mac’s design team increased the side heights to 74 in. to make a “hi-cube” trailer that provides volumes competitive with square dump configurations while maintaining the benefits of a quick and even load release common with the half-round design.

A lower center of gravity through a structurally redesigned front end increases stability and the engineers have been able to maintain the tare weight of less than 10,000 lbs.
