  • Patent number: 10435275
    Abstract: An elevator door device includes a failure detection vane mounted on a safety shoe, and a failure detection roller to be brought into contact with the failure detection vane to turn on a shoe switch. The failure detection roller is mounted only on an OFF-failure detection floor. In a case where the shoe switch is turned off when a door is fully closed on the OFF-failure detection floor, it is determined that the safety shoe has OFF failure, and in a case where the shoe switch is turned on when the door is fully closed on an ON-failure detection floor, on which the failure detection roller is not mounted, it is determined that the safety shoe has ON failure.

  • Patent number: 10399822
    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.
