stairlifts stair lifts stair elevator STAIRLIFTS Home Elevator B.07 stairlifts are equipped with a safety brake that will prevent the carriage from going down in the event of a chain rupture. Safety switches installed on B.07 stairlifts stop the carriage when it reaches the top or bottom of the stairway. The footrest incorporates obstruction sensors which will stop the carriage if an obstacle is encountered on the stairs. If this should occur, press the opposite side of the “UP/DOWN” control switch to run the carriage in the opposite direction. Clear the obstacle from the stairway and proceed as usual. B.07 stairlifts will not run if the position of the seat is different than the normal traveling position. (90° degrees)
