Abstract
A device (42) useful for working on an escalator (20) provides a tread surface (50) that is obliquely oriented relative to an incline (I) of the escalator (20) during a maintenance or repair procedure. A disclosed example is useful for spanning at least a portion of an escalator (20) where the normal operating steps (22) have been removed for purposes of working on the escalator (20). A disclosed example includes a tread surface (50), a riser portion (52) that is at least partially generally perpendicular to the tread surface (50), a first axle hook (54) and a second axle hook (56). The axle hooks rest upon spaced axles (46) associated with the escalator for positioning a temporary step (44) as desired for facilitating working on the escalator.
