    • An advanced control for a powered hand truck. The powered hand truck includes an electric motor, a power source, a programable motor controller, and a transaxle, which are adaptable to existing hand trucks, or may be integrated into a new powered hand truck. The motor controller controls the motor to provide consistent speed independent of load weight or incline, and further provides regenerative braking. The advanced control may be wired or wireless and provides a touch sensitive circuit to command stop if the operator is not holding the handle, and an electronic potentiometer. The wireless control further includes a unique code for validating speed commands and initiates deceleration if the control signal is lost.
    • 动力手推车的先进控制。 动力手推车包括适用于现有手推车的电动机,电源,可编程电动机控制器和变速驱动桥,或者可以集成到新的动力手推车中。 电机控制器控制电机,提供独立于负载重量或倾斜的一致速度,并进一步提供再生制动。 高级控制可以是有线或无线的,并且如果操作者没有握住手柄,则提供触敏电路来命令停止,以及电子电位计。 无线控制还包括用于验证速度命令的唯一代码,并且如果控制信号丢失则启动减速。

    • A powered hand truck for assisting in the movement of objects. The powered hand truck includes an electric motor, a power source, a programable motor controller, and a transaxle, which are adaptable to existing hand trucks, or may be integrated into a new powered hand truck. The transaxle includes a differential allowing easy maneuvering of the hand truck. Power is provided by replaceable/rechargeable batteries. The motor controller controls the motor to provide consistent speed independent of load weight or incline, and further provides regenerative braking. The motor controller also includes diagnostics communicated through a display mounted to the hand truck.
    • 用于协助物体运动的动力手推车。 动力手推车包括适用于现有手推车的电动机,电源,可编程电动机控制器和变速驱动桥,或者可以集成到新的动力手推车中。 变速驱动桥包括一个允许轻松操纵手推车的差速器。 电源由可更换/可充电电池提供。 电机控制器控制电机,提供独立于负载重量或倾斜的一致速度,并进一步提供再生制动。 电机控制器还包括通过安装在手推车上的显示器进行通信的诊断。
