Monitoring equipment for an elevator drive control includes two modules, a safety circuit sensor system and a motor-switching and / or brake-switching circuit, wherein the monitoring of a safety circuit and the consequential actions resulting therefrom takes place exclusively by means of electronic components while avoiding electrically conductive separating locations. By the use of electronic components, electromechanical switching elements, which have electrically conductive separating locations, can be dispensed with. In addition, an appreciable reduction in the noise level is achieved, since switching noises no longer arise. This has an advantageous effect particularly in the case of elevator installations without a machine room. Furthermore, the manufacturing costs can be significantly reduced and a high security and reliability of the monitoring equipment can be ensured by the use of usual electronic components.

Autonomous transport system

An autonomous transport system is disclosed, formed by four main subsystems: a channel subsystem; a vehicle subsystem; a wheel guide subsystem and central control station subsystem. The system is designed for the transportation of people or goods, to be used in tall buildings and in small and large scale urban environments. It comprises unitary vehicles that may move in different directions: horizontal, steeply sloped and also vertical tracks, thanks to novel traction wheel assemblies that roll on carefully designed wheel tracks. The system's cabin maintains the horizontal level / position regardless of the changes of track direction or slanting thanks to pendulum based automatic level control and may rotate up to 180° under normal conditions and even a full 360° turn respect to the wheel assembly in space restricted positions. The cabin is mounted on a cantilever, thereby displacing its center of gravity respect of the wheel guides. Thus, a lever action is established, which presses the wheels against the wheel tracks and therefore enough frictional resistance is obtained so as to avoid wheel slippage on the wheel tracks. The vehicles are moved by non-polluting, electric drives that move and stop them with high energy savings. The vehicle runways are designed taking in account safety features against fire hazards. Several vehicles may be used at the same time and on the same track and may run individually or in groups, conforming a train. The system allows for vehicles to be parked in bypassed positions or else they may be disengaged from the convoy to be used individually.

Brake equipment for holding and braking an elevator car in an elevator installation and a method of holding and braking an elevator installation

Brake equipment for holding and braking an elevator car in an elevator installation, which is arranged to be movable along a brake track in two directions of travel, includes a mount with a brake lining which automatically adjusts under friction couple with the brake track on movement of the elevator car relative to the rail and in that case tightens a first tightening means, which can be released by an actuator. The first tightening means tightens the mount together with the brake lining against the brake track by a biasing force. The brake equipment produces, with unmoved brake equipment and an unreleased state of the actuator, a holding force acting in both directions of travel. The holding force is determined substantially by the biasing force acting on the mount.
