Stairclimber

A stairclimber is a type of trolley fitted with rotating wheels or tracks so that it can be pushed or pulled up or down steps or a stairway.

Stairclimbers can be manual or battery-powered, and are commonly found in wheel, track, push arm or walker variants.

This form of stair climber has a maximum capacity of around 60-80kg and is only found in the manual non-electric variety and very common amongst courier drivers and for lightweight deliveries.

These machines are also slower than push-arm and walker varieties but have the advantage of placing no weight on the operator.

The stair walker types use a long screw thread to extend and retract a 'foot' from the position at which the load is held.
