    Abstract: An energy-saving traction-type elevator and an energy-saving method therefor are presented. The traction-type elevator includes at least one counterbalance unit, each counterbalance unit comprising a traction machine. The traction-type elevator further includes an automatic transmission, a hoist-type lifting mechanism, a power-generating electric motor, and a controller provided in a machine room, and a car, a fixed counterweight and a balancing counterbalance provided in an elevator shaft. The energy-saving method applies the principle of moment balance, whereby adding a separate elevator balancing counterbalance to achieve intelligent counterbalancing of the elevator so that the elevator achieves relative balance, thereby reducing the traction moment and rate of work of the traction machine. When the potential energy of the elevator balancing counter-balance builds up to a high position, the power-generating electric motor can perform centralized power generation, aiding in energy recovery and use.

  • Patent number: 10207894
    Abstract: An elevator system includes an elevator car supported by an elevator rope wrapped around a sheave, such that a rotation of the sheave changes a length of the elevator rope between the sheave and the elevator car thereby controlling a movement of the elevator car within an elevator shaft of the elevator system. An elevator cable is connected to the elevator car and the elevator shaft to carry electrical signals to the elevator car. The operation of the elevator system is controlled in response to receiving a call for a movement of the elevator car requesting a change of the length of the elevator rope. A motion profile of the elevator car causing the requested change of the length of the elevator rope that minimizes the sway of the cable is determined according to a model of a cable relating a sway of the cable to a motion profile. Next, the motion of the elevator car is controlled according to the determined motion profile.

    Abstract: In an elevator apparatus, a hoisting machine includes a driving sheave, and a motor portion that rotates the driving sheave, and is disposed in an upper portion inside a hoistway. A suspending unit is wound sequentially around a first car suspending sheave, a second car suspending sheave, the driving sheave, and a counterweight suspending sheave. The second car suspending sheave, the driving sheave, and the counterweight suspending sheave are disposed on a first side of a car guide rail center line that connects first and second car guide rails when viewed from directly above. A portion of the motor portion is disposed between a back surface of the second car guide rail and a hoistway wall. The driving sheave is disposed so as to overlap with the second car guide rail when viewed from a landing side.

  • Publication number: 20150015280
    Abstract: A method of wear detection of a coated belt or rope includes connecting a wear detection unit to one or more monitoring strands and/or cords of a coated belt or rope. The coated belt or rope includes one or more baseline strands and/or cords exhibiting a first change in electrical resistance as a function of bending cycles of the belt or rope and one or more monitoring strands and/or cords exhibiting a second change in electrical resistance as a function of bending cycles of the belt or rope, greater than the first change in electrical resistance. An electrical resistance of the one or more monitoring strands and/or cords is measured via the wear detection unit. Using at least the measured electrical resistance of the one or more monitoring strands and/or cords, a wear condition of the belt or rope is determined.

  • Patent number: 8925689
    Abstract: An elevator system which utilizes a plurality of independently moving cabs and counterweights in each elevator shaft. Each cab is connected to one or more spatially separated counterweights at different counterweight connection points. The connection points are horizontally shifted on different cabs in order to prevent interference between cabs, cables, pulleys and counterweights. The top cab may have one counterweight cable and may be connected to one or more counterweights by connection points on the roof of the cab. The cabs are mounted on two opposing vertical guide rails, and each guide rail is mounted at the center of one side of the elevator shaft. The system includes a motor attached to each of the cabs by one or more lift cables to facilitate the independent movement of all cabs. Existing buildings can also be retrofit for compatibility with the present invention.

  • Publication number: 20140332321
    Abstract: An elevator includes a car, a counterweight, a suspension working together with the car and the counterweight, and a wheel at least partially wound around by the suspension. The suspension includes a tie beam arrangement with two tie beams and an encasing shell wherein a ratio of the width of the suspension to the height thereof is in a range between one and three. The wheel includes a flute having a flat base for guiding the suspension. When the suspension is unloaded, there is an air gap between the suspension and a guide region of the flute. The suspension is ovalized under loading to close the air gap. The shell is coated, at least in areas, on the outer surface thereof, wherein the coating optionally has a friction-reducing, friction-increasing, and/or wear-detecting effect.
