The TRE-70 is a self-levelling stair climber, able to carry weight of upto 230kg. It is an ideal option for manual or electric wheelchair users and reduced mobility persons. It is easily manouvered - regardless of an individuals strength - on battery powered tracks and can be used on both flat surfaces and inclines, aswell as for stair ascent and/or descent.  It is safe and secure and replaces the need for assistance by more than one person. Aswell as preventing strains or injuries for individuals assisting PRM in access or egress, it stops any need for transferring an individual out of their own wheelchair, enabling a dignified evacuation and independent onward travel in an emergency scenario or general lift breakdown. 

The TRE-52 is much the same, except it is smaller in height, it takes upto 200kg and it is does not have a wynch or self levelling platform. It is perfect for weights less than 200kg.
