THE DIFFERENCE IS CLEAR

Most heavy-duty stair climbing machines are either overcomplicated, locked into place, or require multiple operators to manage bulky cargo. TreadLyft Max Haul Auto is different. With automatic stair sensing, adaptive tilt, and a 926 lb capacity, it does the heavy lifting intelligently.

Built for serious jobs in high-rise buildings and tough logistics environments, it turns what used to take a full team into a one-person operation. Below are 5 ways traditional cargo stair climbers fall short and why Max Haul Auto leads with power, safety, and smart control.

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.
For added confidence, you can extend your coverage to 24 months at checkout for a small additional fee.

We also offer a 30-day satisfaction guarantee. If you’re not completely happy with your Treadlyft and it’s in unused condition, return it for a full refund — no questions asked.
