Abstract: 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.

Abstract: A traction rope adjustment apparatus includes a traction rope pressing device, and a traction rope pulley apparatus. The traction rope lifting apparatus prevents the traction rope sagging, the traction rope pressing apparatus prevents the traction rope drifting, and the traction rope pulley apparatus enables a car and the counterweight to smoothly pass through the traction rope pressing apparatus, thereby implementing forced guidance of the traction rope and the reliable and smooth running of the car and counterweight. The apparatus can meet the demands of variable gradients and can implement reliable running of an inclined running container in variable gradients, such that the traction rope adapts to the different gradients, solving the challenge of the development of an inclined running container that self-adapts to gradients.

Abstract: A slope-adaptive inclined special elevator includes a bumper, an elevator car system, a slope guide rail system, a counter-weight system, a traction machine, a governing rope governor, and a traction rope guiding wheel. The two ends of the traction rope are connected to the elevator car system and the counter-weight system respectively, and the traction rope is towed and lifted under the driving action of the traction machine and the guiding action of the traction rope guiding wheel; over-speed protection is realized by means of the governing rope governor and a safety gear linkage and the bumper; to adapt to slope variations, the car body is leveled automatically by an automatic leveling assembly, the traction rope is guided forcibly via traction rope lifting devices and traction rope pressing devices, and the governing rope is guided forcibly via governing rope lifting devices and governing rope pressing devices.
