THE DIFFERENCE IS CLEAR

Most cargo stair climbers can only handle stairs not the full job. TreadLyft ProLyft Max is built for both flat-ground transport and stair climbing, combining all-terrain wheels with high-grip tracks and smart controls.

Unlike clunky models that need a team or break under pressure, ProLyft Max moves heavy loads solo, folds for transport, and tackles up to 80 floors per charge. It’s made for delivery crews, logistics teams, and field workers who need more than just stair access they need total control, everywhere. Here's why it leaves traditional gear behind.

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.
