Abstract
A motorized stair-lift trolley (1) comprises a sling (4) for the attachment of the load to the trolley, comprising at least one pair of idler stabilizer-wheels (4a) located in a first housing (3) mounted rotatable with respect to the sling to adapt to the inclination of the rail and a means (90) of locking the first housing onto the sling; as well as a second housing (10) that houses the means (11) of moving the trolley and that is forced to rotate with respect to the sling to the same angle to which the first housing is rotated.
