ELEVATOR SERVICE PANEL
An elevator system including an elevator car frame including an interior side, a service panel operably coupled to the interior side of the elevator car frame, the service panel including a panel interior side and a panel exterior side, and configured to operate between an open and closed position, an elevator car operably coupled to the elevator car frame, the elevator car including an interior cavity, wherein the panel exterior side is disposed within the interior cavity when the service panel is in an open position.
Hydraulic-boosted rail brake
A hydraulic-boosted rail brake is provided for use with an elevator having a guide rail. The rail brake includes a braking plate having friction material, a spring package in communication with the braking plate, a hydraulic cylinder, a piston housed at least partially inside the hydraulic cylinder, and a brake controller. The braking plate is selectively movable relative to the guide rail, and the spring package biases the friction material to interact with the guide rail to cause braking. The piston is in communication with the braking plate and is selectively: (a) movable in a release direction to diminish or overcome force from the spring package; and (b) movable in an engage direction to supplement the force from the spring package. The brake controller selectively causes the piston to move in the release direction and in the engage direction.

ELEVATOR SYSTEM, BRAKE SYSTEM FOR AN ELEVATOR SYSTEM AND METHOD FOR CONTROLLING A BRAKE SYSTEM OF AN ELEVATOR SYSTEM
An elevator system includes an elevator car, at least one elevator drive arranged in an elevator shaft and a support strap, wherein the elevator car is arranged in the elevator shaft for movement via the support strap by the elevator drive. A brake system includes a car braking unit associated with the elevator car and a drive braking unit associated with the elevator drive. The car braking unit and the drive braking unit can together be controlled from a common brake control device. The brake system can be used for new elevator system installations and for retrofitting existing elevator systems.

ELEVATOR COMPRISING A DECENTRALIZED ELECTRONIC SAFETY SYSTEM
An elevator includes a drive, a car operatively connected to the drive to traverse along a travel path, at least one guide rail positioned along the travel path to guide the car, a safety brake arranged on the car to exert a braking force on the guide rail, and a safety system. The safety system includes a first safety control unit and a second safety control unit that monitor a safety condition of the elevator. The first safety control unit outputs a stop signal to the drive, in particular to a drive brake and/or to a frequency converter of the drive, and the second safety control unit outputs a trigger signal to the safety brake to bring the elevator into a proper safety condition when an impermissible safety condition of the elevator is detected.

Overspeed safely brake
An overspeed brake system is described to engage a safety cable and subsequent brake system once a threshold speed is reached. An overspeed safety kit may be installed on an elevator system or lift car, to identify a threshold speed and engage a brake lever to activate a braking system. One or more brake engagement devices may be applied to limit the force on the brake lever during a fall, thereby preventing potential damage to brake components, while cushioning the deceleration.
