A machine assembly for use in an elevator system includes a support structure having a first end connected to an adjacent support member and a second end supported by at least one car guide rail. The support structure is arranged generally perpendicular to the support member and is configured to receive at least one component of the elevator system.

A method for erecting an elevator system in an elevator shaft of a building includes performing at least one lift process to adapt a usable lift height of the elevator system to an increasing height of the building. During the lift process, a drive platform, which supports an elevator drive machine and, via a flexible support, an elevator car and a counterweight, is lifted along at least one elevator car guide rail. Prior to the lift process, the at least one elevator car guide rail is elongated in the upwards direction above the drive platform and fixed to a shaft wall of the elevator shaft by at least one auxiliary support in the region of the elongation. After the lift process, the at least one auxiliary support, which then lies below the drive platform, is replaced by a final guide rail mounting which is designed differently than the auxiliary support.

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 system and method for adjustably positioning elevator guide rail. The system includes: an adjustment device arranged on a moving platform and having a clamping portion and a powering portion, the clamping portion being arranged to be capable of clamping an elevator guide rail to be installed through a power output from the powering portion and moving in a first, a second and/or a third directions, and the moving platform being capable of moving up and down in the first direction; a detection device arranged to detect current movement characteristics of the clamping portion when the elevator guide rail is not clamped or has been clamped by the clamping portion; and a control device connected to the detection device and the adjustment device, and arranged to adjust the position of the clamping portion in place by controlling the powering portion according to the movement characteristics.

A universal bracket for a rail system includes a positionable and alignable main support and at least one mounting point for at least one rail of the rail system. The main support has two guides that are inseparably connected to the main support in order to guide one plumb bob in each case, the mounting point and the guides being arranged in fixed positions relative to one another.
