  • Patent number: 8646224
    Abstract: Construction apparatus for use within an elevator hoistway are provided. The construction apparatus include a span member having a first end and a second end. A sill attachment is connected to the first end of the span member and configured to seat against a building sill. A support member is connected to the second end of the span member and configured to seat against a second side of the elevator hoistway, wherein the second side of the elevator hoistway is opposite the building sill. A plurality of apertures is arranged on the span member and configured to allow a connection to a hoist device. The span member is configured to rotate about the sill attachment.

  • Patent number: 8113319
    Abstract: An elevator may include an elevator car, one or more hoisting ropes, a traction sheave, an overspeed governor, at least one safety gear, a locking mechanism, and guide rails. The car may be suspended by the one or more hoisting ropes. The traction sheave may move the car using the one or more hoisting ropes. The at least one safety gear and locking mechanism may be fitted in conjunction with the car. The overspeed governor may be configured to activate and release, via a linkage, the at least one safety gear during operation of the elevator. The locking mechanism may be configured to activate and release, by operatively acting on the linkage, the at least one safety gear during installation, maintenance, or installation and maintenance of the elevator. When activated, the at least one safety gear may engage one of the guide rails to lock the car in place.

  • Publication number: 20100252369
    Abstract: An elevator, comprising an elevator car (1), car guide rails (3) on one side of the elevator car (1), an elevator shaft or equivalent (5), at least one stop block (9) attached to the car guide rails (3) or to the elevator shaft or equivalent (5), at least two movable stop blocks (7) attached to the elevator car (1), the latter stop blocks (7) being arranged to be moved transversely relative to the elevator shaft direction into a position aligned with at least one stop block (9) attached to the car guide rails (3) or elevator shaft or equivalent (5) and away from said position aligned with said stop block (9). The aforesaid at least two movable stop blocks (7) attached to the elevator car are connected to each other by a horizontal shaft (10) oriented substantially in a direction parallel with the wall of the elevator car (1) on the side of the car guide rails (3) to synchronize the motion of the movable stop blocks (7).

  • Patent number: 7258202
    Abstract: The invention provides an elevator having a car movable along guide rails mounted in a shaft. The elevator comprises an inspection control station mounted on top of the car and accessible via a movable control station cover, blocking means for selectively preventing movement of the car into a safety space within the shaft and actuation means for actuating the blocking means. The actuation means is configured for concurrent movement with the control station cover. Accordingly, a temporary safety space is automatically created within the shaft as the maintenance technician opens the control station cover to move the car using the inspection control station.

  • Publication number: 20030015379
    Abstract: A manual brake release control structure having a linking member cooperates with an escape and protection mechanism for an elevator to protect an emergently braked elevator cab against inertial slip during brake release. By pulling an escape pulling cable outside the cab with a normal force, the braked cab is released to move and rotate a rotary shaft of a driving motor of the elevator. The rotary shaft in rotating causes a cam connected thereto to rotate and thereby reciprocates the linking member up and down that in turn causes an actuating arm and a flexible long member to repeatedly release and depress a braking device of the elevator, so that the cab is intermittently braked and released to move upward or downward at a reduced safety speed.
