摘要:
An elevator system comprises at least two independently operable elevator cars in each of a plurality of elevator shafts within a building. The elevator system can include at least one first elevator shaft having a first and a second region, with the first region extending from a ground level to sub-ground levels, and with the second region extending from the ground level to a top floor. A first elevator car may move within the first region and a second elevator car may move within the second region, in the same shaft independently of each other.

A system and method for minimizing compensation rope sway by altering the natural frequency of compensation ropes using servo actuators. The rope sway may be minimized by moving the compensation sheave to adjust the tension of the compensation rope or adjusting the position of the termination of a compensation rope to account for changes in the position of a structure. Servo actuators may also be used to re-level the elevator car to account for rope stretch.

Disclosed is a termination device for an aramid-based elevator rope having a high breaking strength. The termination device comprises a socket having a cylindrical, tapered internal passageway adapted to receive a corresponding wedge. The wedge includes a semi-cylindrical passageway in a substantially helical configuration to increase the surface area between the associated rope and the wedge. The termination device clamps the length of rope between tapered portions of the socket and the semi-cylindrical passageway of the wedge with a substantially uniform application of force on the cross-section of the rope.
摘要:
An elevator system comprises at least two independently operable elevator cars in each of a plurality of elevator shafts within a building. The elevator system comprises at least one first elevator shaft having a lower first and a lower second region, where a first elevator car moves within the lower first region of the first elevator shaft and a second elevator car moves within the lower second region. The first and second elevators are moveably controlled independently of each other within the first shaft. The system also includes at least one second elevator shaft having an upper first and an upper second region, where a third elevator car moves within the upper first region of the second elevator shaft and a fourth elevator car moving within the upper second region. The third and fourth elevator cars also are moveably controlled independently of each other.
摘要:
The invention provides a system and method for handling power outages in a multiple car elevator system in a building having a plurality of floors. The system includes an energy calculator connected to the elevators, and determines a total energy of the elevator system, a total energy required to handle a power outage, a plan to prepare for a power outage and a plan to handle a power outage. The system also includes a movement controller connected to the elevator(s) and the energy calculator. The movement controller receives the plan to prepare and the plan to handle from the energy calculator, and the movement controller executes the plan to prepare if there is no power outage and the movement controller executes the plan to handle if there is a power outage.

An active guiding and balance system that retains the active control of an elevator system in the presence of displacement. This active control may be maintained via the use of an actuator that tailors Lorentz force relative to the level of displacement along a non-linear continuum.

摘要:
An elevator car is provided with at least one moveable aerodynamic control surface which is moveable to generate counter forces to aerodynamic forces resulting from airflow around the elevator car. Aerodynamically suitable surfaces may also be provided on either end of the elevator car.
