Step Lifts.

Designed to provide both wheelchair and pedestrian access at the same doorway where the use of ramps is impracticable, these lifts rise to a height of 1000mm and are available for both indoor and outdoor use. Portable models are also available.
Quite compact and ideal for short-travel access over one to three steps to an entrance.
Step lifts maximise the use of space avoiding the need for ramps. Often specified with up to three bridging steps, these lifts allow access to both ambulant and wheelchair users alike.
