THE DIFFERENCE IS CLEAR

Most industrial stair climbers are either too bulky, too basic, or just not built for the job. TreadLyft Max Haul Core strikes the perfect balance high load capacity, rugged performance, and practical portability.

Unlike outdated lifts that struggle with tight turns or require extra setup, Max Haul Core folds fast, maneuvers easily, and powers through 80 floors per charge. Built for real movers, facility teams, and warehouse pros, it redefines what a heavy-duty stair climber should be. Here's how it outperforms the rest where it matters most.

5 Reasons Why You Should Avoid Traditional Stair-Climbing Dollies

  1. No Powered Assistance: Traditional dollies rely entirely on human effort, putting immense strain on the back, knees, and arms especially on stairs.
  2. Unsafe for Heavy or Bulky Items: Without a motorized system, balancing large appliances or stacked boxes on stairs becomes risky, increasing the chance of accidents or damage.
  3. Zero Stability Features: Most manual dollies lack locking tracks, stair grips, or intelligent braking systems essential for safe use on angled steps.
  4. Physically Demanding: Requires strength, coordination, and stamina making it inaccessible for older adults, caregivers, or solo users.
  5. Inefficient and Slow: Moving items manually takes more time and usually requires multiple people, slowing down daily logistics or household tasks.

COVERED BY WARRANTY

Every Treadlyft stair climber comes with a 12-month full manufacturer warranty — no registration required.
