    • A suspension work platform hoist system having reduced reactive power to produce a hoist system power factor of at least 0.95 when operating at a steady state full-load condition as the motor raises the work platform. The hoist system power factor takes into account all the power consuming devices of the suspension work platform hoist system as well as a suspended conductor system that connects the constant frequency input power source to the hoist, which is often in excess of several hundred feet. The hoist system power factor may be achieved by incorporating a reactive power reducing input power system into the suspension work platform hoist system. The reactive power reducing input power system decreases the magnitude of the reactive power of the motor producing a high hoist system power. The reactive power reducing input power system may include an AC-DC converter and a regulator system in electrical communication with a DC-AC inverter that is in electrical communication with the motor.
    • 一种悬架工作平台升降机系统,当电动机升起工作平台时,在稳态满载状态下工作时,具有降低的无功功率以产生至少为0.95的起重系统功率因数。 起重系统功率因数考虑到悬挂工作平台升降系统的所有功率消耗装置以及将恒定频率输入电源连接到通常超过几百英尺的起重机的悬挂导体系统。 起重系统功率因数可以通过将无功功率减小输入电力系统并入悬架工作平台升降系统来实现。 无功功率降低输入功率系统降低电动机的无功功率的大小,产生高的起升系统功率。 无功功率降低输入电力系统可以包括与与电动机电连通的DC-AC逆变器电连接的AC-DC转换器和调节器系统。

    • A suspension work platform hoist system having a variable acceleration motor control system and a tilt control system. The tilt control system includes at least one tilt sensor to sense a tilt angle of the work platform and generate a tilt signal. A tilt controller receives the tilt signal and generates a speed control signal, which is used by the variable acceleration motor control system to control the operation of the hoist motors to maintain a tilt angle setpoint as the work platform is raised and lowered. The tilt control system may include a settling mode having a settling tilt angle setpoint, wherein the settling mode prevents the work platform from being raised or lowered until the tilt angle of the work platform reaches the settling tilt angle setpoint.
    • 具有可变加速电机控制系统和倾斜控制系统的悬架工作平台升降机系统。 倾斜控制系统包括至少一个倾斜传感器,以感测工作平台的倾斜角度并产生倾斜信号。 倾斜控制器接收倾斜信号并产生速度控制信号,该速度控制信号由可变加速电机控制系统用来控制起重电动机的操作,以在工作平台升高和降低时保持倾斜角设定值。 倾斜控制系统可以包括具有稳定倾斜角度设定点的沉降模式,其中沉降模式防止工作平台升高或降低,直到工作平台的倾斜角达到稳定倾斜角设定点。

    • A suspension work platform hoist system for raising and lowering a work platform is provided. The system incorporates at least one hoist attached to the work platform and in electrical communication with a motor control system. The motor control system is attached to the work platform and is in electrical communication with a constant frequency input power source and the hoist motor. The motor control system controls the acceleration of the work platform as it is raised and lowered by controlling the hoist motor. The system may further include a tilt control system to allow the work platform to reach and maintain a tilt angle setpoint as the work platform is raised and lowered, and/or a system to reduce the reactive power associated with its operation.
