The disclosure relates to a guide rail to guide the car of an elevator system. The guide rail is designed as a section with a cavity (-) and/or integrated cooling fins to cool the guide rail.

Guide rail for an elevator system and an elevator system

A guide rail for an elevator system may comprise at least two rail elements that together form a guide rail portion having a functional running track that extends in a travel direction. Each of the rail elements may be connected to a shaft wall of the elevator system. Furthermore, the at least two rail elements may be adjacent and spaced such that the at least two rail elements can thermally expand freely in the travel direction. Additionally, the at least two rail elements in a region of the functional running track may have mutually opposite borders that have complementary profiles. An arbitrary cross section of the guide rail portion perpendicular to the travel direction in the region of the functional track may run through at least one of the two adjacent rail elements.

Guide rail for an elevator system

An elevator may include a brake apparatus such as a safety apparatus or a service brake, for example. The brake apparatus may be designed to generate a stepped braking force for braking an elevator car of the elevator. A plurality of brake cylinder assemblies may be configured so as to supply different braking forces. The brake cylinder assemblies may in some cases include a piston, a spring, and a brake pad. Moreover, a valve assembly may be utilized by one or more of the brake cylinder assemblies. Additional features of the brake apparatus may involve a compressor, a pressure accumulator, a pressure regulating valve.

Elevator with a braking device

The present disclosure relates to a car door for a lift car having a guide mechanism and a door leaf. The guide mechanism comprises in this case a sliding shoe, which is connected to the door leaf of the car door. Furthermore, the guide mechanism comprises a receiving part which surrounds the sliding shoe on at least three sides. The sliding shoe has, in a sliding direction, an extent which corresponds to at least 30% of the extension of the door leaf in this direction.

Car door

An elevator may include a braking device such as a safety gear system or a service brake, for instance. The braking device may include a hydraulically-acting brake for braking an elevator car of the elevator. The braking device may further include a hydraulic unit with a pump assembly, a brake cylinder assembly, and a valve assembly for ventilating the brake. Further, the hydraulic unit may be fastened to the braking device.
