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

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/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.

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.
