    • An automatic material handling crane system services a plurality of stations in an industrial plant. The system includes a crane which is movable on a track, a mast which is carried by the crane, and a material handling mechanism which is carried by the mast. Position encoders provide signals indicative of the position of the crane on the track and the mast with respect to the crane. Both manual and remote controls are provided to operate the crane system. The manual control is carried by the crane and provides manual control signals. The remote control is positioned at a remote location with respect to the crane and stores a schedule of operations of the crane, mast and material handling mechanism. The remote control signals provided by the remote control are based on the schedule and on status information relating to the crane, the mast and material handling mechanism. A crane-carried control provides control signals to control the positioning of the crane and the mast, and to operate the material handling mechanism as a function of signals from the crane and mast position encoders and either the manual control signal or the remote control signals. The crane-carried control also provides the status information to the remote control as a function of the signals from the crane and mast position encoders. A communication link transmits the remote control signals to the crane-carried control, and transmits the status information to the remote control.
    • 自动材料处理起重机系统为工业厂房中的多个站提供服务。 该系统包括可在轨道上移动的起重机,由起重机承载的桅杆和由桅杆承载的材料处理机构。 位置编码器提供指示起重机在轨道和桅杆上相对于起重机的位置的信号。 提供手动和遥控器来操作起重机系统。 手动控制由起重机承载,并提供手动控制信号。 遥控器相对于起重机定位在偏远的位置,并存储起重机,桅杆和物料搬运机构的操作时间表。 由遥控器提供的遥控信号基于与起重机,桅杆和材料处理机构有关的时间表和状态信息。 起重机控制装置提供控制信号以控制起重机和桅杆的定位,以及根据来自起重机和桅杆位置编码器的信号以及手动控制信号或遥控信号来操作材料处理机构。 起重机控制还根据来自起重机和桅杆位置编码器的信号向遥控器提供状态信息。 通信链路将遥控信号发送到起重机控制,并将状态信息发送到遥控器。
