The SHERPA tracked stair lift is suitable for non-ambulatory subjects who need to overcome flights of stairs in buildings not equipped with suitable equipment, thus proving useful for overcoming architectural barriers.
It consists of a metal structure that moves on rubber tracks, equipped with a rudder for guiding and anchoring a wide range of wheelchairs.
The control and emergency buttons are ergonomically arranged on the tiller.
The movement is entrusted to an electric motor managed by an electronic control unit that allows soft starts and stops and provides a high level of driving comfort.
The power supply is battery-powered and the residual charge is monitored on the control panel.
The crawler tracks allow for forward and reverse maneuvers, while a pair of maneuvering wheels intervene when changing direction, extending automatically.
The movement of the machine body is implemented through a button located on the control panel on the back.
The load-bearing frame of the structure is made of electro-welded steel and treated with a cataphoresis process, while the rudder is made of steel tube trusses.
The shockproof thermoformed polystyrene covers finish the product with a refined and modern design.
The extremely low height of the stairlift makes it easier to insert various types of wheelchairs.
The new front and rear LED lighting devices ensure excellent visibility in both directions of travel even in poor lighting conditions or sudden blackouts.

Mechanical innovations for greater safety
- Battery pole protection
- Self-resetting internal fuse protection
- Machine bottom protection
- Elimination of side openings

Visual messages and audible alarms for safer and more secure use
- Low battery alarm, very inhibited
- Visual and audible alarm for low battery level
- Excessive load signal
- Excessive slope, acoustic signal
- Negative tilt, anti-tip acoustic signal
- Excessive motor absorption control; if the machine collides with an obstacle the device blocks the motion in that direction and only takes reverse motion commands
- Functions inhibited with battery charger inserted
- Acoustic alarm active during maneuvers with the additional wheels lowered
- Stand-by after 5 minutes of inactivity and audible alarm every 30 seconds
