Abstract: A method for controlling movement of an elevator car during an emergency stop includes the steps of determining the load of the car; determining the travel direction of the car; and monitoring the speed of the car. When the car is determined to be either lightly loaded and travelling downwards, or heavily loaded and travelling upwards, brake torque is applied only when the speed of the car reaches zero, as slowing of the car can be accomplished solely by virtue of the balancing factor of the car's counterweight.

Abstract: In an elevator installation an elevator cage is arranged to be movable along guide rails and the elevator cage is equipped with a brake system possibly with two safety brakes. The safety device is activated by way of control devices which can trigger the safety device from critical or non-critical events. The control devices further include a function for automatic resetting of the safety brake when an event, which is evaluated as non-critical, is indicated as a reason for triggering the safety brake. Resetting of the safety brake takes place through execution of pre-defined resetting steps of the elevator cage.

Abstract: A device for actuating an electromagnetic elevator brake in an elevator installation includes at least two outlets connected to a coil of the brake, and a control system. Also provided is a switchable dissipation device, which is connected to the two outlets. In a rapid actuation operating mode, the control unit switches the switchable dissipation device such that the magnetic energy stored in the coil dissipates rapidly. Rapid actuation of the elevator brake is thus made possible.

Abstract: An elevator car for an elevator system includes a car door, a car door mechanism, at least one car door panel, a door drive motor, and a drive control device for the door drive motor. The car door mechanism thereby supports the car door panel. The drive control device includes an operator module having an operator panel, wherein the operator module is disposed on the elevator car so that the operator panel can be operated from the roof of the elevator car and through an opened shaft door from a building floor.

Abstract: An elevator installation has an elevator car carrier that can be displaced in a travel space, a first elevator car arranged on the carrier in an adjustable manner, and a second elevator car arranged on the carrier. A drive unit on the carrier drives a traction device to adjust the first elevator car relative to the carrier. The traction device forms a closed loop and is guided over a drive roller and at least one guide roller, which rollers are arranged on the carrier. The guide roller is displaceable on the carrier to set tensioning of the traction device.

Abstract: A maintenance method for an elevator includes provision of a service platform in a lower region of the elevator, in particular a shaft pit, for later maintenance work, wherein the service platform was previously mounted for installation purposes on at least one set of car guide rails and served in the installation process as a working platform for mounting elevator components in the elevator shaft, in particular on a shaft wall.

Abstract: An installation method for an elevator includes the following steps: provision of a counterweight frame to be moved along counterweight guide rails, provision of an installation platform to be moved along car guide rails, and loading of the counterweight frame with at least one elevator component and movement of the counterweight frame to the position of the installation platform.

Abstract: An elevator has an elevator car supporting frame that can travel in a travel space provided for a journey of the elevator car supporting frame. The elevator installation is also provided with a first elevator car and a second elevator car arranged on the elevator car supporting frame. Furthermore, a hydraulic moving element is arranged in a lower end region of the travel space.

Abstract: In this elevator system, a traveling body has arranged upon it a safety gear for braking and holding the traveling body tight on the guiderail, or on a braking rail. The safety gear is connected to a device for actuating the safety gear, which can also actuate the safety gear. The device for actuating the safety gear contains a coupler body, which can be pressed against the elevator hoistway, possibly against the guiderail or braking rail, wherein actuation of the safety gear is effected by a relative movement between the pressed-on coupler body and the safety gear. For this purpose, the coupler body can contain a curved coupler surface, which, in case of need, is brought into engagement with the elevator hoistway, or with the guiderail or braking rail.
