Abstract: Elevator landing door structure, comprising a door sill (1, 5) fixed to the lower edge of a landing door opening, an overhead supporter (2, 9) and at least one door panel (3) movably mounted on the overhead supporter. Furthermore, the door structure comprises vertical frames (4, 6) fixed to the door sill (1, 5) on either side of the door opening, the overhead supporter being attached to said vertical frames. The vertical frames (4, 6) are fastened by their upper parts via junctures that are rigid in the horizontal plane but capable of yielding in the vertical direction.

Abstract: The invention relates to a procedure for fixing the guide rails (3) of an elevator car (4) and/or counterweight, in which procedure the guide rails (3) of the elevator car and counterweight are fixed to the wall (12) of the elevator shaft or to an intermediate member laid across the elevator shaft. The car guide rails (4) and counterweight guide rails (3) are locked at a desired distance from the wall by fixing elements (11) used to fix the counterweight guide rails (3).

Abstract: A procedure and an apparatus triggers the safety gear of an elevator at a speed lower than the gripping speed. The overspeed governor of the elevator comprises a pulley (3) driven by the safety gear rope and a brake (5) connected to it by knuckle pins (14,14'). The brake is provided with centrifugal weights (16,16'). Eccentric cams (15,15') and a brake disc (6) are also provided for the overspeed governor. At a speed lower than the gripping speed, using a separately controlled solenoid (30) attached to the overspeed governor, the brake (5) is caused to engage the pulley (3) by driving the plunger of the solenoid into the path of rubber rollers (31,32) rotating with the centrifugal weights.

Abstract: The invention relates to a procedure for mounting the guide rails for an elevator car or counterweight, wherein the guide rails are attached to an intermediate beam laid across the elevator shaft, the beam being attached at least by one of its ends to opposite walls of the elevator shaft, and to a mounting system implementing the procedure. At least two steel plates (5,6) or equivalent are placed oppositely on the vertical sides of the intermediate beam (2), the upper and lower edges of the plates extending at least somewhat above and below the intermediate beam (2).

Abstract: An elevator safety apparatus is disclosed which is designed to be mounted on an elevator car, which car moves along guide rails; said apparatus comprising a frame, an area for wedge housings formed in the frame, and wedges placed in the wedge housings on each side of a guide rail; the wedges gripping the guide rail when the safety apparatus is activated, the wedges being placed relative to each other such that the wider end of one wedge points upwards while the wider end of the second wedge points downwards. To allow safety apparatus action in both an upward and downward direction, the apparatus is provided with an activating mechanism connected to and moving both wedges, and an overspeed governor, or the equivalent, for controlling the activating mechanism.
