New Mack Rolloff Trucks For Sale

New Mack rolloff trucks pair a high RBM frame with heavy hoist subframes and tail sections designed to take repeated container impacts. Hoist rails, crossmembers, and deck plates deliver subframe floor strength, carrying point loads from worn container floors without buckling, and tail rollers or sliders distribute weight to keep the load angle controlled. Choose cable hoist for simplicity and lower tare, or hooklift for faster container swaps and multi body flexibility, both integrate cleanly on Mack Granite or TerraPro chassis.

Payload is driven by tare weight, axle spec, and wheelbase. Mack MP7 or MP8 power with mDRIVE HD and creeper ratios keeps gearing tight and weight down compared with torque converter automatics, while still giving precise low speed control for staging cans. Specify single or double frame and inner liners where route severity demands. Typical front axles run 18,000 to 20,000 pounds, tandems 46,000 to 52,000 pounds, with steerable lift axles to satisfy bridge law and protect steer tires. Aluminum wheels, air tanks, battery boxes, and a compact 50 to 70 gallon hydraulic reservoir can remove hundreds of pounds without sacrificing durability. Hoist capacities around 60,000 pounds are common, verify reeving, sheave diameter, rear section thickness, and tail plate design so structure and floor contact points match the boxes you haul.

Refuse and scrap operations attack paint and hardware daily, so corrosion resistance is critical. Look for zinc rich primer or e coat under high build paint on frames, powder coated hoists with sealed weldments, galvanized rear aprons, stainless or zinc nickel hardware and fittings, and sealed Deutsch connectors. Mack harness routing, abrasion sleeves, and elevated junctions help keep salt out. Composite fenders, polymer shims on hoist rails, and UHMW wear pads reduce metal to metal contact that scrapes coatings, slowing rust creep and preserving appearance and resale.

Thermal integrity under stop and go duty protects uptime. Mack cooling modules with high capacity fans, large charge air coolers, and proper shrouding hold engine temperatures steady. Size the PTO and hydraulic pump for your target cycle time, then add a thermostatic oil cooler and return filtration to keep viscosity and cleanliness in spec during summer heat or long drags up grades. ClearTech aftertreatment, heat shielding near the stack, and auto regen programming manage exhaust temperatures during slow routes. Remote or dual controls, load hold and counterbalance valves, a robust body prop, and automatic chassis lubrication further stabilize operation and reduce heat from friction at pins and bushings.
