An elevator roller guide assembly that provides enhanced ride comfort. The assembly includes a chassis, a stop plate mounted to the chassis, a face wheel enclosure that at least partially encloses the face wheel and is connected to a plurality of leaf springs, and a pair of side wheel enclosures connected to the face wheel enclosure by the plurality of leaf springs. The side wheel enclosures each support a side wheel in a fixed relation to the other side wheel. The side wheel enclosures are operably connected to the stop plate by a pair of vertical plates. A multi-axis damper extends from the stop plate to engage the face wheel enclosure and dampen oscillation of the wheel enclosures during operation. A set of delta diameter wheels across all four guides reduces coincident flat spots to improve ride quality. Also, a wheel force gauge is integrated with the face wheel enclosure.

A damper unit for an elevator, for the purpose of reducing vertical vibration of a stopping elevator car, has at least one roller that, in an active position, is in contact with a guide rail for the elevator car and can be rotated about an axis of rotation. For damping rotary movements during vertical vibration of the stopping elevator car, the roller is connected to a rotation damper.

A roller guide for an elevator car includes at least one roller rotatably mounted on an axis. The roller guide further includes a support element for supporting the axis, and at least one braking element for the roller for damping vertical oscillations of the elevator car. The brake element is a magneto-rheological fluid.

The disclosure relates to a lift installation having a lift car which can be moved along a guide rail. The lift installation here comprises at least a first pair of rollers and a second pair of rollers. The guide rail runs between the two rollers of the first pair of rollers and between the two rollers of the second pair of rollers. The lift installation also has an apparatus for subjecting the lift car to a retaining force, wherein there is a horizontal offset between the point at which the retaining force takes effect and the center of gravity of the lift car, and therefore the lift car is subjected to a first torque.

An elevator guide having a base attached to an elevator component, a guide riding along a portion of a rail and a spring biasing the guide in contact with the rail. The guide includes one or more of the following: (i) a guide support member operably associated with the guide for movably supporting the guide so that the guide can move toward and away from a corresponding surface of the rail member wherein the guide support member has a plurality of spring engagement sections configured to vary a system effective spring rate; (ii) a roller including a non-metallic rim molded about a bearing; (iii) two independently adjustable stops and, (iv) an opening adjustment member mounted about a notch in the base to vary the distance between the base and the rail. The opening adjustment member has a width and/or depth greater than a width and/or depth of the notch.

A system for transferring elevator cars from a first elevator shaft to a second elevator shaft including: a propulsion system configured to move an elevator car through the first elevator shaft and the second elevator shaft; a transfer carriage configured to move the elevator car from the first elevator shaft to the second elevator shaft through a transfer station, the transfer carriage including: an elevator car containment slot to receive the elevator car; and a car retention mechanism configured to secure the elevator car and the propulsion system within the transfer carriage while the transfer carriage moves from the first elevator shaft to the second elevator shaft, wherein the propulsion system is configured to move the elevator car from an elevator system within the first elevator shaft onto the transfer carriage and off the transfer carriage to an elevator system within the second elevator shaft.

A robotic transporter system for elevator cars including: a propulsion system configured to move an elevator car through an elevator shaft; and a robotic transporter configured to move the elevator car within a parking area, the robotic transporter including: an elevator containment slot to receive the elevator car and the propulsion system of the elevator car when the elevator containment slot is aligned with the elevator shaft.

A roller system, a roller brake device and an elevator system. The roller brake device is used for the roller system. The elevator system includes the roller system. The roller system comprises a roller assembly and a roller brake device, the roller brake device includes: a body, the roller brake device is mounted to the roller assembly by the body; an actuation device mounted to the body; and a brake connected to the body in a pivotable manner, and the actuation device can move the brake from a rest position to a brake position, wherein the brake engages and brakes a roller in the roller assembly at the brake position, and the brake is disengaged from the roller at the rest position.

An adjustable roller-guide shoe for guiding an elevator car or a counterweight of an elevator installation contains a roller carrier, which can be fastened on the car or the counterweight, a guide roller and a roller spindle, which is arranged in the roller carrier and accommodates the guide roller. The roller spindle is positioned in the roller carrier by an adapter having an installation contour which matches a corresponding accommodating contour of the roller carrier. The adapter is configured to be fixed in different installation positions in relation to the roller carrier, and thus the roller spindle can be placed in different positions in the roller carrier, depending on the installation position of the adapter. It is thus possible for the roller-guide shoe to be operated with different roller diameters or to be adapted to different rail-web dimensions.

Disclosed is a ropeless elevator system having a car mover operationally connected to an elevator car, the car mover configured to operate autonomously and move along a hoistway lane, thereby moving the elevator car along the hoistway lane, wherein the car mover is connected to a top or bottom of the elevator car, via a coupling device.
