Dump Trailers

The MAC series of Dump Trailers and Straight bodies offer four design configurations. We offer frameless and frame type trailers that are engineered and manufactured to meet your rigorous hauling demands. Whether you are hauling, rock, sand, gravel, asphalt, scrap, salt, construction materials, agricultural products and everything else in between, MAC stands ready to be tested!

MAC TRADITIONAL – The original fully welded “Sheet & Post” square design is rugged, time tested, a proven mainstay and is a recognized leader in the dump industry.

MAC “MVP” MACLOCK® SMOOTH SIDE – incorporates the unique technology of a distinctive structural snap together side panel that represents the alliance of innovation, engineering and construction by utilizing extruded 6061 T-6 aluminum hollow core, multiple void side panels having full welds on the interior joint and provides a weldless mirror finish exterior side wall for imaging, a design that has been built, tested and proven in Europe since the 1980’s. The aerodynamics of the “MVP” (MAC Vertical Panel) and narrow width dimension of the hollow core panels have proven to enhance fuel economy while at the same time allowing you to gain additional cubic yardage for greater payloads and increased profits. With varying thicknesses of the panel’s interior wall side, the extrusions are strategically placed based upon application, wear and weight considerations.

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” lower front end and a 6” lower backend with 31” 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.

MAC STEEL – is in a class of its own with a design and construction to meet geographic needs nationally when it comes to steel trailers. Whether you are looking for the maximum capacity maximum durability of the 90 cubic yard, AR450 “SCRAPMAC” for the brute applications, the traditional radius or half round design for heavy abrasive hauls such as but not limited to sand, gravel, and dirt, MAC Trailer offers it all.

The better we understand your needs, the better prepared we are to provide unparalleled solutions that will offer operational benefits, reduced maintenance costs and higher residual values.

Falling is a serious concern for all drivers, maintenance individuals and site staff when they walk the top of a pneumatic to open-close the manholes or perform service. As a result, the MAC Trailer Design Team has engineered, extensively tested and now offers a retractable set of hand rails as an optional safety feature available on all the new MAC PNEUMACTIC tank trailers.

The handrails, constructed of tubular aluminum, are operated by an air valve located forward of the rear fenders and when raised, are securely locked into position. When retracted, the rails fold into a locked position that is lower than the height of the manholes.

As an added measure of overall safety, when the rails are raised, the brakes on the truck-trailer are locked to prevent any movement until the handrail is lowered.

The unique safety feature of the retractable handrails is a proprietary design of MAC Trailer and is available as a retrofit kit for all existing trailer makes.

MAC Trailer has become recognized as the nation’s foremost leader in the manufacturing of tipper and moving floor transfer trailers. Simply, MAC knows the transfer industry and knows the importance of constructing a trailer that will withstand the most demanding of conditions, rigors and abrasive operations associated with the loading and unloading of mass volume and heavy bulk materials from waste, to wood, to agricultural, to recyclables, to scrap.

That is why fleets, operators and transport companies turn to MAC, they know they can rely on the structural integrity, durability and dependability that is designed, engineered and built into the top rails, the rear gates, hinges, bumpers and rear pockets of all MAC trailers.

MOVING FLOORS – Whether you are transporting MSW or C&D to a landfill, bulk mulch or wood products to a wholesaler, agricultural products for unloading into a hopper, plastics to a recycle center or crushed cars-scrap-white goods to a metal reprocessing site, choose the design-construction of either the original fully welded aluminum sheet & post with side skins to a guage of .250, or the smooth sided “MVP” (MAC Vertical Panel) MACLOCK® configuration that incorporates 2 1/4” hollow core aluminum extruded panels. Then, coordinate the drive unit (leakproof or conventional) with the slat profile best suited for your application. Slats or decking range from the aluminum smooth surface traditionally used for movement of agricultural-wood materials, the high impact designs for solid waste or the steel slat for the more robust aggressive abrasive loads of scrap, white goods, crushed cars or sand.

TIPPER TRAILERS – When maximum payload is your primary objective, and you are unloading via a tipping platform, go no further, the MAC Tipper is all about volume, low tare weight and designed for the long haul. From tapered designs with lengths to 53’ the MAC Tipper can provide volumes up to 148 cubic yards. Choose your design of either the fully welded sheet and post or the greater capacity “MVP” MACLOCK® extruded aluminum panel construction. At MAC, we have the facilities to produce single units or large quantities to meet your contract deadlines.

MULTI – AXLE TRANSFER TRAILERS – When your specification or regulatory requirement demands axle configurations from tri-axle to 8 axles, to multiple spreads and lifts or sliders, you can rely on MAC as each trailer layout is engineered to ensure all axle positions and plumbing will meet your weight distribution or bridge law regulations. So transporting in Canada where SPIF is a requirement or in Michigan, New York or other geographic areas where multi-axles are a necessity to permit your heavy loads – NO PROBLEM, you can be assured MAC will have you road legal.
