Mac 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!


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


This 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.


This 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.


This 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.


From tandem flatbeds, to multi-axles, to B & A-train combinations, to single drop decks, the Road Warrior or to our latest addition the MLP-6 and MLP-8 Flatbed, the MAC aluminum flatbeds have earned their stripes through a reputation for being a trailer of structural strength appealing to a spectrum of transporters. Our 200,000 square foot facility located in Salem, Ohio, with state of the art manufacturing capabilities, has already exceeded expectations and is currently being applauded by the market as a leader in platforms.


Leading the MAC line-up, the tandem flat is recognized as the benchmark of aluminum platforms in North America. This premium trailer, whether built with the M-52, M-60, M-72 or M-80 main beams, is engineered to handle evenly distributed material loads such as lumber, skids of shingles, block or bagged sand too extreme concentrated steel coil loads. MAC has earned the proud reputation for holding its arch under the most severe of loads.


MAC provides a lightweight, high load capacity drop deck trailer to meet today’s unique and special load demands. MAC’s special process of forming the all aluminum neck prior to the final heat treatment of the metal, intern maintains the strength properties of the alloy and enhances the structural integrity of the design. The step deck is available in overall lengths from 40’ to 53’ with 10’ and 11’ upper deck lengths. With rear deck height options of 41” with 255/70R22.5 tires, 38” with 265/70R19.5 tires and 35” with 245/70R17.5 tires, the MAC drop deck offers a wide capability of lower deck height choices and opportunities. (Note when choosing a sliding axle the deck heights will increase by 1”).


If you haul coils, block or heavy materials, you need an extreme trailer that can handle extreme loads – you need a MAC. The heavy haul market requires a trailer that will handle the most robust of loads and that is why you will see more fleets and owner operators pulling the MAC 29” M-72 & M-80 beamed trailers. Whether you are pulling a single trailer, B-Train or need to meet the Canadian SPIF requirements, the MAC multi-axle platform trailer should be your choice, as it has earned its stripes in North America as the leader throughout the industry of heavy material haulers.


The “ADVANTAGE X-tender” 53 ft. to 65 ft. with a weight comparable to a standard combo with same base specifications lengthens opportunities to fleets and owner operators to accept loads they commonly would have to turn down due to length constraints. Targeting the pre-cast, rebar and pipe haul markets, the “ADVANTAGE X-tender offers great opportunities to handle these special load requirements with ease, plus having the light weight to handle common flatbed commodity loads.



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.


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. Maximize Cubic Yard capacities by utilizing the tapered/ Drop-Deck design with volumes up to 154 Cubic Yards.


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/Drop-Deck designs with lengths to 53’ the MAC Tipper can provide volumes up to 154 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.


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.
