MACSIMIZER HALF ROUND – has proven itself to be a lightweight rugged workhorse within the MAC family of dump trailers. Designed with a radius bulkhead, that offers a low profile front end complete with a lower center of gravity. This will provide a 7 inch lower front end and a 6 inch lower backend with 31 inch less flat space on the bulkhead compared to the Standard flat bulkhead. To help MACsimize your load, aerodynamics, and increase fuel economy our MACsimizer Half Round has a tare weight as low as 8,900 pounds (less liner and tarp); offering the volume of a traditional square dump and will provide the benefits of how the round designed body releases the load, keeping the material centered throughout the entire dumping cycle not to mention it is the lightest materials trailer in the industry today.
