This maintenance trestle (10) is arranged in the lift cage (2). A platform(12), from which the operations in the lift shaft (1) are carried out, is at the same time also the floor of the lift cage (2). The platform (12) is adjustable in height by means of lifting equipment (13) operating on the scissors principle. For the transport of persons and goods, the platform(12) is in the position shown by dashed lines, in which the lifting equipment(13) is stowed under the platform (12) or under the cage floor (12). For maintenance operations in the lift shaft (1), the platform (12) is steplessly adjustable in height up to the illustrated position. With the maintenance trestle (10) in work setting, the prescribed over-travel(~) is achieved, because the distance between the cage ceiling (1.1) and the platform(10.1) is determinative for that.
