General description
Our product is designed to fulfil the requirements of conveniently transporting disabled or elderly people up
and down staircases and at the same time be easily integrated into existing surroundings.
One great advantage of the design of our lift is the upper travel rail; which can also be used as a hand rail
when the lift is not in use. The travel rails do not need to be lubricated, this reduces the possibility of soiling by
dust and dirt. When in motion the travelling speed is limited to a comfortable and practical 0.15 m/s and final
drive is achieved by means of a rack and pinion drive.
The noise level during operation is less than 63 dB (A). The load bearing capacity is clearly indicated on the
identification plate.
The operational load is supported on the travel rails by two set of rollers, two diagonal rollers, the gear wheel
and opposing bearing. The supporting rollers are fixed onto two parallel mounted stainless-steel tubes. An
electrical motor propels the unit by means of a gear wheel via a self-locking, form fitting connection to a worm
gear, which is capable of withstanding the horizontal and vertical loads to which it is subjected.
The travel rails are constructed out of an upper stainless-steel tube which also serves as a handrail and a lower
stainless-steel tube with a toothed rack welded to it. The necessary attaching elements are fixed to an existing
wall, stanchion posts or a steel structure.
An arresting device (emergency brake) ensures that in the event of a mechanical or electrical failure, the lift
remains stationary and does not descend down the travel rails.
