TRANSPORT HEAVY LOADS SAFELY UP AND DOWN STAIRS

CargoMaster A400 - Effortless transportation of heavy loads

The Cargomaster A400 masters even challenging transport tasks with ease and reliability. Thanks to the infinitely variable speed and the two innovative climbing modes, this electric stair climber offers extremely flexible use - ideal for transporting heavy and bulky loads.


Continuous climbing mode:
In continuous climbing mode, the A400 climbs steps continuously and efficiently in one go, enabling fast and smooth transport - perfect for many steps and heavy loads.


Single step mode:
Single step mode is particularly useful when precision is required.

This mode is ideal for narrow stairwells or sensitive loads and is particularly advantageous for beginners.


Compact transport solution:
The Cargomaster A400 is not only powerful, but also space-saving. When folded, it has a compact size of 1187 x 595 x 516 mm and fits easily into smaller vehicles. This makes it the ideal solution for flexible use and transport in urban environments or for changing locations.
