摘要： A passenger conveyor system (20) has a drive module that engages only one side (50) of the step chain loop (30). In a multiple drive module arrangement, at least one of the drive modules (40B) engages both sides (50, 52) of the step chain loop while another engages only one side (50). The inventive arrangement is not sensitive to spacing (54, 56) between the drive modules. Another example embodiment includes a synchronizing module (60) that engages both sides (50, 52) of the step chain loop (30).

摘要： An elevator rescue system includes a power source of back-up electrical power. A manually-operated, rescue enable switch switchably permits the transmission of electrical power from the power source to a motor brake coil of an elevator car during a rescue operation such that the energized coil releases the motor brake to move the car to a desired landing. A speed detector measures the speed of the elevator car and thereupon generates a speed control signal corresponding to the speed of the car. An overspeed detection circuit has a first input for being actuated when receiving electrical power from the power source, a second input for receiving the speed control signal, and an output for transmitting electrical power to the motor brake coil when the speed control signal is below a predetermined value and for automatically stopping the transmission of electrical power when the speed control signal becomes higher than a predetermined value. A manually-operated brake release switch has an input and an output. The input is coupled to the output of the overspeed detection circuit, and the output is to be coupled to the motor brake coil of the elevator car for transmitting electrical power to release the motor brake when the brake release switch is closed.

摘要： An elevator car includes a hold closed feature for an elevator car door. The hold closed feature maintains the elevator car door in a hold closed position when the elevator car is not at a landing or is "parked" at a landing. The hold closed feature includes a profiled ramp disposed on the elevator car and a roller disposed on the elevator car door. The roller engages the profiled ramp during the hold closed position of the elevator car until a certain predetermined force is exerted for the roller to disengage from the profiled ramp.

摘要： A speed command signal is applied to a variable voltage, variable frequency controller for driving a three-phase induction motor that operates a positive displacement pump for supplying fluid to a hydraulic elevator drive cylinder. An accelerometer mounted on the car provides an acceleration-related feedback signal to the car speed command input of the motor control, thereby to dampen low frequency resonant modes of the elevator car. A sensor on a check valve between the hydraulic pump and the hydraulic cylinder provides a signal indicative of when the pump pressure is sufficient to support the car load, and the check valve begins to open; the signal is used to memorize ramped-up motor speed at that point, which equals the motor speed necessary to overcome pump leakage in order to support the car. That speed is added into the car speed command at the input of the motor controller to compensate for pump leakage. The acceleration damping of low frequency resonant modes of the elevator car may be utilized in roped elevator systems.

In the method, a first step provides a fluid cylinder comprising a piston displacably mounted in a housing containing pressurized fluid is provided in the first step. The housing has first and second seals in register with the piston. In a second step, the second seal is applied to maintain pressure within the housing when the piston is in a static state. In a third step, the first seal is applied to maintain pressure within the housing and the second seal relaxed prior to displacement of the piston. In a fourth step, the second seal is applied to maintain pressure within the housing and the first seal relaxed subsequent to the displacement of the piston. An apparatus is provided for applying one of the first or second seals and relaxing the other of the first or second seals, before and after displacement of the piston.

摘要： The flow of hydraulic fluid to and from an hydraulic elevator piston is controlled by a motor-actuated spool valve operated by a microprocessor. To lower the elevator, a main check valve is opened by a down piston using hydraulic fluid from the system. Pressure is equalized on both sides of the main check valve just before the latter is opened thereby allowing the use of a smaller down piston which uses less hydraulic fluid. This results in smoother car motion during descent of the car. The addition of a valve bleed passage to equalize pressure on both sides of the check valve also prevents rapid descent of the elevator car in the event that the spool valve were to be open at the time descent commences.

摘要： A roller apparatus is provided. The roller apparatus may include a bearing wheel configured to rotatably couple the roller apparatus to a roller shaft, and a resilient member radially disposed about the bearing wheel and configured to contact a guiderail at different magnitudes of loads. The resilient member may include a first section of a first diameter and a second section of a second diameter. The first section may be caused to deflect in response to loads within a first load range, while the second section may be caused to deflect in response to loads within a second load range. The resilient member may exhibit a stepwise increase in stiffness with a gradual increase in load.

摘要： An exemplary elevator system includes an elevator car. At least one guiderail guides movement of the elevator car. The guiderail has a length in a direction of movement of the elevator car and a depth generally perpendicular to the length. A plurality of flat belts are situated relative to the elevator car such that movement of the flat belts for causing movement of the elevator car is approximately four times a corresponding movement of the elevator car. A plurality of sheaves is situated for directing the flat belts as the belts at least partially wrap around the sheaves. The plurality of sheaves remains fixed near one end of the guide rail. The plurality of sheaves rotate about coaxially aligned axes and have a collective width along the axes that is no greater than the depth of the guiderail.
