The holding brake is designed for application of a mechanical braking action relative to a guide rail of the elevator installation so that the elevator cage after actuation of the holding brake retains its vertical position. The holding brake comprises a locking mechanism which is designed so that it acts from two opposite sides on the guide rail.



Cabling configuration for railless elevators

Tue, 17 Mar 2015 08:00:00 EDT

An elevator including a car is arranged in a shaft. A set of compensator cables are attached to a bottom of the car and engaged with a compensator drum. A set of hoist cables are attached to a top of the car and engaged with a hoist drum to move the car vertically in the shaft, wherein the set of compensator cables and the set of hoist cables are configured to only move the car vertically.



Lifting apparatus

Tue, 17 Mar 2015 08:00:00 EDT

The invention relates to a lifting apparatus of a type which can be used to allow movement of goods to and from and between first and second goods storage areas. The apparatus is located in a space between openings into both of said storage areas and includes a platform which can be raised in the vertical plane so as to allow differences in height between floors of the respective goods storage areas to be taken into account such that for example goods can be moved onto the platform of the lifting apparatus from a first floor height on a first goods storage area to a floor of a second goods storage area at a different height. The lifting apparatus can be used to move goods to and from a floor of a goods storage area which is at the similar height to a support surface on which the other of the goods storage areas is located, with the other of the goods storage areas typically being a vehicle trailer.



Rope braking apparatus

Tue, 10 Mar 2015 08:00:00 EDT

The present invention relates to an elevator wire rope braking apparatus, and more particularly, to a rope braking apparatus which prevents partial abrasion of the wire rope while increasing braking efficiency by preventing a deviation in the pressure applied to the wire rope by a pressure plate moving in a straight line to apply pressure to the wire rope. Since the pressure application is based not on a hydraulic method but on a purely mechanical structure using only a spring elastic force, environmental pollution caused by hydraulic oil may be prevented and product cost may be reduced.



Movable body derailment detection system

Tue, 10 Mar 2015 08:00:00 EDT

An elevator installation has a guide rail of a predetermined length and a movable body configured to move along the guide rail up and down a hoistway. A proximity sensor is mounted on the movable body to be in a predetermined proximity of the guide rail. The proximity sensor is configured to detect whether or not the proximity sensor is at the predetermined distance to the guide rail. A controller coupled to the proximity sensor acts upon an indication that the proximity sensor is not at the predetermined distance to the guide rail to switch the elevator installation to a secure state.
