20080302611 | Machine Room with a Raised Work Platform in Front of the Controller for Elevators and Elevator Equipped Therewith - The machine room according to the invention with a flat rope or thin rope drive machine is, characterized in that the elevator controller device ( | 12-11-2008 |
20100155184 | ELEVATOR HAVING A SHALLOW PIT AND/OR A LOW OVERHEAD - The elevator has a car movable vertically within a shaft between lower and upper end positions and a drive system coupled to a traction system for controlling movement of the car. A limit switch which is open when the car is in a selected distance range from one of the end positions. The limit switch forms part of a power line supplying power to the drive system for controlling movement of the car in a direction towards that end position in an inspection operation. Thus movement of the car is prevented only in that direction when the car is in the selected distance range in an inspection operation. | 06-24-2010 |
20100163346 | SAFETY DEVICE FOR SECURING MINIMUM SPACES AT THE TOP OR BOTTOM OF AN ELEVATOR SHAFT BEING INSPECTED, AND ELEVATOR HAVING SUCH SAFETY DEVICES - The safety device for an elevator system comprises a retractable element mounted on a support. The retractable element has a stopping position in which a catch portion of the retractable element projects from the support to engage a triggering member of a safety brake associated with an elevator car as the elevator car traveling in a selected direction approaches a selected vertical position, and a retracted position. An actuator selectively controls the position of the retractable element. A position sensor is responsive to the position of the retractable element to make sure that it is in its stopping position when needed. | 07-01-2010 |
20110048863 | SINGLE BRAKESHOE TEST (ELECTRICAL) FOR ELEVATORS - A control arrangement ( | 03-03-2011 |
20110088983 | ELEVATOR BRAKING DEVICE - An elevator assembly ( | 04-21-2011 |
20140284144 | SINGLE BRAKESHOE TEST (ELECTRICAL) FOR ELEVATORS - An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature. | 09-25-2014 |

20130327598 | ELEVATOR CAR MOVEMENT CONTROL IN A LANDING ZONE - An exemplary method is useful for controlling movement of an elevator car in an elevator system that includes a machine that selectively moves the elevator car and a machine brake that selectively resists movement of the elevator car. The method includes determining whether the elevator car is near a landing and determining whether a door of the elevator car is open. A desired operation includes desired movement of the elevator car while the elevator car is near the landing and the door is open. A determination is made whether the elevator car moves other than according to the desired movement. The machine brake is applied for stopping movement of the elevator car responsive to elevator car movement other than the desired movement while the elevator car is near the landing and the door is open. | 12-12-2013 |
