An elevator safety device includes: a lower beam; and an emergency stop device mounted parallel to the lower beam in order to perform an emergency stop of an elevator car, wherein the lower beam includes: a first side member; a second side member disposed opposite the first side member; a front support member configured to be coupled to and to support front portions of the first side member and the second side member; and a rear support member configured to be coupled to and to support rear portions of the first side member and the second side member.

A position adjusting device and method for elevator frame, an elevator frame, and an elevator. The position adjusting device includes: a connection portion configured to be suitable for being selectively attached to a side surface of a vertical connection member for elevator frame; a matching portion extending on a plane perpendicular to the connection portion, and including one or more threaded through holes; and one or more adjusting mechanisms including a head and a threaded rod, the rod being configured to match the threaded through hole, and a tip of the rod being configured to be suitable for matching with the surface of a horizontal connection member for elevator frame.

An elevator car roof includes two toe boards for mounting the elevator car roof at a mounting position to uprights of an elevator car. Each of the toe boards has projecting brackets for holding the elevator car roof at the uprights in the mounting position. Each of the uprights includes a slot for receiving one of the projecting brackets when the elevator car roof is held in the mounting position by the uprights. The projecting brackets and the slots can be formed to prevent a wrong orientation of the elevator car roof relative to the uprights.

A foldable elevator structure having a plurality of members is shown having each current member sequentially attached between a preceding member and a succeeding member. This connection schema continues until the last member is attached to the first member and a completed enclosed structure is formed such that all members have been attached. In this fashion, the foldable structure is foldable between each set of two adjacent members.

An elevator car frame, an elevator car and an elevator system. The elevator car frame includes a top, a bottom and uprights extending between the top and the bottom and deviating from a longitudinal middle portion of the elevator car frame, and at least one of the uprights is provided with car guide shoes arranged to enable the elevator car frame, after being installed in an elevator hoistway, to move along a car guide rail disposed in the elevator hoistway through the car guide shoes.

A transportation system for a building includes a horizontal travel lane, a vertical travel lane, and a transportation cab configured for travel along the horizontal travel lane and vertical travel lane, a cab floor of the transportation cab orientable such that the cab floor is non perpendicular to a gravitational force acting on the transportation cab. A method of operating a transportation system for a building includes locating a transportation cab at a travel lane positioned at a building, accelerating the transportation cab in a non-vertical direction along the travel lane and orienting a cab floor of the transportation cab to be non-perpendicular to a gravitational force acting on the transportation cab during non-vertical acceleration of the transportation cab.

This invention is concerning a car suspending pulley device including a pair of beams provided parallel to each other on a lower portion of a car and a car suspending pulley arranged between the pair of beams and supported by the pair of beams. A weight suspending pulley is provided on a counterweight. The car and the counterweight are suspended from a main rope wrapped around the car suspending pulley and the weight suspending pulley. A compensating member is suspended between the beams and the counterweight. The compensating member includes a funicular body having a first end portion connected to only one of the pair of beams and a second end portion connected to the counterweight. The first end portion of the funicular body is located in a region of the one beam when viewed in a vertical direction.

An elevator system and a support column assembly. The elevator system includes a support column, with the bottom end thereof connected to a bottom mounting base, and the top end thereof connected to a top mounting base; a counterweight arranged in the support column; a car having a through hole penetrating in a vertical direction, wherein the car is arranged around the support column via the through hole; and a traction assembly, wherein the car is connected to the counterweight via the traction assembly, and the car and the counterweight reciprocate along the length direction of the support column under the traction of the traction assembly.

The present invention relates to a frame (20) for a car (10) of a passenger/freight elevator. The invention further relates to a car provided with such a frame. Finally, the invention also relates to an elevator comprising such a car. According to the invention the frame (20) comprises an upright (21, 22) having connected thereto a support (23, 24) which comprises two parts placed at an angle relative to each other, which parts are integrally connected. One part (23A, 24A) is connected here to the upright and the other part (23B, 24B) to a bottom part (33) of the car (10).

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.
