    Abstract: An example elevator system may include a shaft in which at least one elevator car can be vertically displaced. The elevator car may be coupled to a counterweight via a cable arrangement wherein the cable arrangement has at least one cable portion. Horizontal deflection of the cable portion can be limited by at least one limiting member. In some examples, the at least one limiting member may be configured as a limiting roller that is mounted laterally alongside the cable portion such that it can be rotated about an axis of rotation and can be made to rotate by a controllable rotary drive that depends on a speed and a movement direction of the cable portion.

    Abstract: In an elevator apparatus, an abnormal acceleration detecting mechanism includes a mass body that operates in connection with movement of the car, the abnormal acceleration detecting mechanism operating a safety device using a force of inertia that is generated by the mass body if an acceleration that exceeds a predetermined set value arises in a car. A breakage detecting means detects breakage of a suspending means that suspends the car. A resistance force applying apparatus applies a resistance force to a mechanism for activating the safety device such that the resistance force is applied when breakage of the suspending means is not detected by the breakage detecting means and the resistance force is reduced if breakage of the suspending means is detected by the breakage detecting means.

  • Patent number: 8943695
    Abstract: Method for installing the hoisting roping of an elevator, wherein the first elevator unit to be moved is disposed at a suitable point in the elevator hoistway, and the second elevator unit to be moved is disposed at a suitable point in the elevator hoistway, which first elevator unit is an elevator car and which second elevator unit is a counterweight, or vice versa. The first and/or second section of the hoisting roping is connected to its elevator unit via a diverting pulley system such that when the diverting pulley system is still separate from the elevator unit, the section in question of the hoisting roping is arranged to travel under the diverting pulley system of its elevator unit, and the diverting pulley system is lowered, when reeved, downwards into the proximity of its elevator unit, after which the diverting pulley system in question is fixed to its elevator unit.

A plurality of attachment holes for fixing the top member are formed in the bottom member. A plurality of attachment holes for fixing the top member are formed in the bottom member. The first bolts pass through the attachment holes and fix the top member to the bottom member. The second bolts pass through the attachment holes and fix the top member to the bottom member. The top member is fixed to the bottom member using a smaller number of the first bolts than the number of the attachment holes. The top member is fixed to the bottom member using a smaller number of the second bolts than the number of the attachment holes.
