A frictional damper for an elevator system includes one or more friction pads configured to move between a first position, and a second position defined by engagement of the one or more friction pads to the guide rail. An actuation unit urges the one or more friction pads into and out of engagement with the guide rail. The actuation unit includes a hydraulic actuator operably connected to the one or more friction pads to urge movement of the one or more friction pads into and out of engagement with the guide rail via hydraulic fluid pressure. The hydraulic actuator includes a hydraulic cylinder containing a volume of hydraulic fluid and a hydraulic piston located in the hydraulic cylinder and operably connected to the one or more friction pads. An electromagnetic actuator selectably urges hydraulic fluid to apply a force to the hydraulic piston, urging the movement of the friction pads.

Electrohydraulic damper for elevator system

An electromagnetic machine includes a universal circuit board and a plurality of universal coils. The universal circuit board includes a first coil configuration imprint and a second coil configuration imprint. The plurality of universal coils each including a positive lead and a negative lead for electrical connection to one of the first and second coil configuration imprints.

Universal electromagnetic machine

An electromagnetic machine includes a rotor and a stator. The rotor is adapted to rotate about an axis. The stator includes a support structure, a plurality of bobbins engaged to the support structure, and a plurality of electric coils with each one wound about a respective bobbin of the plurality of bobbins.

Electromagnetic machine

A method and system for managing an elevator system (), includes providing a plurality of elevator cars () to travel in a hoistway (), and selectively introducing and removing at least one of the plurality of elevator cars () to and from the hoistway () via a loading station ().

Configurable multicar elevator system

A transfer station () for a ropeless elevator system hoistway () is provided. The transfer station () includes a first lane (), a second lane (), and a parking area () located proximate one of the first lane () and the second lane (). The transfer station () also includes a plurality of carriages () moveable within the first lane (), the second lane (), and the parking area (), the plurality of carriages () configured to support and move an elevator car (). The transfer station () further includes a cassette () configured to support and move the plurality of carriages (). The transfer station () yet further includes a guiding member () engaged with the cassette (), wherein the position of each of the plurality of carriages () relative to the first lane (), the second lane () and the parking area () is modified by horizontal or vertical movement of the cassette ().

Transfer station for a ropeless elevator system with redundancy of subcomponents and parking zone

A guidance mechanism for an elevator car is constructed and arranged to move along a lane defined at least in-part between two opposing first and second lane structures of a stationary structure. The guidance mechanism includes a first support structure supported by the first lane structure. The first support structure includes a first retainer face disposed between the elevator car and the first lane structure that substantially faces the first lane structure, and is spaced from the first lane structure. A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.

Elevator car guidance mechanism

An elevator system includes a hoistway; an elevator car to travel in the hoistway, the elevator car having permanent magnets mounted thereto; a stator mounted in the hoistway, the stator coacting with the permanent magnets to control motion of the elevator car in the hoistway, the stator including: a plurality of modular coil modules, each coil module including stacked coil assemblies, each coil assembly including stacked coil units, each coil unit corresponding to one phase of the stator.
