Mac Trailer for Portland cement

Mac Trailer’s lighter-weight UltraMac pneumatic cement trailer is designed specifically for hauling Portland cement.

The UltraMac is designed with aluminum parts throughout to reduce weight. The vessel is all aluminum mill finished construction with a smooth exterior and internal ring reinforcements. The Mac unitized all aluminum frame features front and rear aerodynamic enclosures.

Mac “stairs” at the rear have integrated risers and raised handrails. There are aluminum fenders, anti-spray/anti-sail mudflaps.

The trailer includes Air-Weigh’s QuickLoad Trailer Scales as standard equipment. QuickLoad scales convert the air pressure in the trailer’s suspension into a ground weight rating which is displayed on touchscreen. To prevent overloading, built-in LED warning lights will flash when the load approaches its overweight threshold.

The cement trailer comes with Hendrickson Intraax AANT23 suspension with 25,000-pound rated air bags. It also has Hendrickson integrated axles and Hendrickson HLS wheel ends with aluminum hubs and fused brake drums. A rear axle mounted leveling valve features an integrated automatic suspension dump valve.
