An apparatus for guiding and braking an elevator system traveling body movable along a guide track includes a holder fastened to the body, a guide device and a braking device. The holder transmits guiding forces between the guide device, guided on at least one track surface in the longitudinal direction, and the body. The guide device is held on and is elastically movable relative to the holder transverse to the longitudinal direction by at least a predetermined tolerance distance. The braking device includes a carrier and a braking element movable between a deactivated configuration, in which a braking surface of the braking element is laterally spaced apart from the guide track, and an activated configuration, in which the braking surface abuts the guide track, in a reversible manner by an activation distance transverse to the guide track. The carrier of the braking device is rigidly coupled to the guide device.

Apparatus for guiding and braking a travelling body of an elevator system, which body is to be moved along a guide track

A method for forming a guide structure in an elevator shaft provides a guide structure configured to guide an elevator car during vertical travel in the elevator shaft. The method includes the following steps: moving a tool, such as a milling tool, vertically along the elevator shaft, wherein the tool is precisely positioned with respect to the horizontal position thereof within the elevator shaft, and forming the guide structure by removing material on a shaft wall of the elevator shaft using the tool.

A brake device for braking an elevator installation traveling body movable along a guide rail includes a holder mounting a brake element having a brake surface movable relative to the holder between a freewheel position and a braking position. In a deactivated configuration, a pretensioning element does not exert any force moving the brake element towards the braking position, and in an activated configuration exerts such force. In a retaining state, a release element retains the pretensioning element in the deactivated configuration, and when activated into a released state, the release element changes the pretensioning element into the activated configuration. In an unactuated state, a friction-generating element does not abut the guide rail and, in an actuated state generates friction by abutting the guide rail to exert a force on the brake element and force the brake element towards the freewheel position.

Brake device, e.g. with an eccentric element, for braking a traveling body that can be moved in a guided manner along a guide rail in a movement direction

A brake device for braking a traveling body movable along a guide rail in a movement direction includes a holder mounting a brake element that has a brake surface directed toward the guide rail, the brake element being movable relative to the holder between a free-running position and a braking position. A pretensioning element is activated to exert a force that moves the brake element toward the braking position. A release element holds the pretensioning element in a holding state and is activated into a released state to reconfigure the pretensioning element from a deactivated configuration into the activated configuration. A pressing element in an actuated state generates a force on the brake element in a direction toward the guide rail to enable a reset of the brake device.

A method and a catching device are used to catch a traveling body in an elevator system wherein traveling body is movable along a rail. The catching device includes a first braking element, a second braking element, a first guide element, a second guide element and an actuating element. The first braking element and the second braking element are brought into contact with the rail for braking. A first linear bearing is formed between the first braking element and the first guide element and a second linear bearing is formed between the second braking element and the second guide element. Both guide elements are moved between a rest position and a braking initial position, the actuating element moving the two guide elements from the rest position into the braking initial position.

Electronic catching device that can be easily reset

A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element. The first guide element can be moved between a rest position and a braking initial position. The actuating element is designed to move the first guide element from the rest position into the braking initial position, more particularly to activate the safety brake. The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.

A method for configuring security related configuration parameters is used in a passenger transport installation that includes at least one sensor exchanging sensor signals with a control. The sensor detects operating parameters within the passenger transport installation and emits corresponding sensor signals. The control controls security related functions of the passenger transport installation taking into account the sensor signals and the configuration parameters. The method includes: comparing the sensor signals with a predefined key signal pattern; operating the control temporarily in a configuration mode exclusively if the compared sensor signals correspond to the key signal pattern; and configuring the security related configuration parameters during the configuration mode. An installation-specific sensor (e.g. optical sensor or magnetic field sensor) functions as an interface to put the control into configuration mode in a targeted manner, e.g. by a test piece with a barcode maintained in the field of view of the optical sensor.

A locking system that locks and unlocks a door of an elevator car travelling along a track having stopping points and associated stopping point zones includes a lock mechanism having a locking position wherein the door is immobilized in a closed position and an unlocking position wherein the door can be opened, an actuator for bringing the lock mechanism into the locking and unlocking positions, and a control device activating the actuator to bring the lock mechanism into the unlocking position when the car is located in the region of a stopping point zone. A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.

A monitoring device for an elevator system is used with an assembly device for assembling a shaft retrofit and a method for monitoring an assembly platform. The monitoring device monitors movements of an elevator car and includes a sensor system for detecting a movement variable and at least one analysis device that evaluates the detected movement variable and compares it to a threshold. If the threshold is exceeded, a signal output is triggered to actuate a brake/catching device. The monitoring device selects the threshold from specified thresholds based on a state of the monitoring device. The specified thresholds include at least one normal operation threshold, and the monitoring device indicates a normal state as soon as specified connection elements are connected to it. The monitoring device further contains a checking routine for determining a state of the monitoring device, and selects the threshold from specified thresholds based on the state.

Elevator car movement monitoring device, assembly device and assembly method for an elevator 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.

Elevator comprising a decentralized electronic safety system

In an elevator installation, an elevator car is movably arranged alongside guide rails and the elevator car is equipped with a brake system with preferably two safety brakes. A movement monitoring system monitors the movement parameters of the elevator car and triggers corresponding warnings or safety measures, if permissible threshold values are exceeded or it provides determined adjusted movement parameters to an elevator control. The movement monitoring system determines a first movement parameter in a time interval and detects an acceleration of the elevator car. The movement monitoring system determines the time interval for determining the adjusted movement parameter as a function of the detected acceleration.

In an elevator installation an elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. An elevator braking device includes a brake element, a force store, which is constructed to press the brake element against the brake surface, and an actuator, which can act on the brake element. A method of operating the braking device includes the actuator pressing, in a first operational setting, the brake element against the force of the force store away from the brake surface or to hold it at a spacing therefrom, and the actuator freeing, in a second operational setting, the brake element and allowing the force store to press the brake element against the brake surface.

An elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. The elevator braking device has a brake housing and a force store. The brake housing is mounted to be displaceable between a first position and a second position. The force store acts on the brake housing and pushes the brake housing in the direction of a second position. In addition, the elevator braking device includes an actuator which can act on the brake housing and keep the brake housing in a first position. The actuator in its first setting can hold the brake housing in the first position against the force of the force store. In a second setting the actuator enables pushing of the brake housing into the second position. A brake element is thereby brought into contact with the brake rail.
