A kit of parts for securing a plurality of fixtures to an elongate support member is described. The kit of parts comprises a plurality of attachment members. Each attachment member comprises an aperture for receiving the elongate support member and a fixing detail adapted to attach a fixture to the attachment member. The aperture is larger than a lateral dimension of the elongate support member to provide a gap between the attachment member and elongate support member when received in the aperture. The kit of parts also comprises a plurality of locking elements. Each locking element is adapted to be received in the aperture in the gap between the attachment member and the elongate support member to secure the attachment member to the elongate support member by friction. Further, each attachment member is adapted to engage an adjacent attachment member when secured to the elongate support member by at least one said locking element to form a hollow column secured around the elongate support member for supporting a plurality of fixtures.

A hydraulic elevating platform having no guide rails and an elevating method. A hydraulic power pack drives three parallel hydraulic cylinders to work synchronously, thereby implementing the rising and falling of an elevating platform; when the elevating platform reaches a predetermined floor, an upper electric pushrod pushes a pedal assembly out, and then the pedal assembly drives a pedal to rise by means of a pedal elevating system until the pedal is flush with the surface of a loading table of the elevating platform; outward-swinging doors between the elevating platform and a floor open to form pedal guardrails; then sliding doors open and a man can step onto a stair via the pedal assembly. An eccentric loading adjusting means eliminates eccentric loading to achieve balance about the center of gravity, thereby eliminating the eccentric loading of the platform. The elevating platform is simple in structure, safe, reliable, and easy to maintain. The elevating platform, placed within a spiral stair, is convenient for movement of crowds and cargo delivery at certain scenarios and is widely applicable. The elevating method is simple to implement and effectively solves the eccentric loading problem caused by reasons such as outstretching of a pedal of a hydraulic elevating platform and uneven distribution of people on the elevating platform, so that the hydraulic elevating platform is more stable and reliable during operation.

A staircase area at which a staircase is installed across a first floor and a second floor is provided in a building. A part of the staircase area is a non-installation space in which a staircase is not installed, and a lifting space through which a transport robot moves up and down between the first floor and the second floor is provided using the non-installation space. The lifting space and a staircase hall having a spandrel wall there between are adjacent to each other the second floor. An opening through which the transport robot moves between the lifting space and the staircase hall is provided in the spandrel wall.
