    • A load guide for securing a load relative to a boom includes a base secured to the boom and a retractable arm assembly attached to the base. The base presents a front portion that is proximate a load supported by the boom. The arm assembly includes a pair of load-securing arms movably connected to the load guide base, each of the arms being movable between an operative position and a retracted position, wherein moving the arms from the operative position to the retracted position includes rotating each of the arms toward the other arm, and further includes translational movement of each of the arms away from the front portion of the load guide base.
    • 用于固定负载相对于起重臂的负载引导件包括固定到动臂的基座和附接到基座的可伸缩臂组件。 基座呈现靠近由吊杆支撑的载荷的前部。 臂组件包括可移动地连接到负载引导器基座的一对负载固定臂,每个臂可在操作位置和缩回位置之间移动,其中将臂从操作位置移动到缩回位置包括使臂 臂朝向另一个臂,并且还包括每个臂远离负载导向器底座的前部的平移运动。

    • A plurality of individual frames or stampings provided in a sheet strip material by a stamping device are passed in proximity to a sensing device. As each individual frame or stamping is passed in proximity to the sensing device, the sensing device provides a voltage signal to a controller. The voltage signal is proportional to the amount of, or mass of, metallic material in each frame or stamping and the distance between the frame or stamping and the sensing device. The controller generates an individual waveform from the voltage signal for each frame passed in proximity to the sensing device. Each individual waveform is a function of the position of the movable portion of the stamping device for one cycle. As the plurality of individual frames are passed in proximity to the sensing device, a plurality of individual waveforms are generated within the controller. The waveforms are compared within the controller to detect a deviation between waveforms. A deviation between waveforms indicates a sheet strip material misfeed condition within the stamping device. If a sheet strip material misfeed condition is detected, the controller provides a signal to the stamping device to initiate stoppage of the stamping device. If desired, the plurality of individual waveforms may also be compared within the controller to detect a deviation in the configuration of the frames or stampings produced by the stamping device from a desired frame or stamping configuration.
    • 通过冲压装置设置在片材材料中的多个单独的框架或冲压件通过在传感装置附近。 当每个单独的框架或冲压件通过在感测装置附近时,感测装置向控制器提供电压信号。 电压信号与每个框架或冲压件中的金属材料的量或质量成比例,以及框架或冲压件与感测装置之间的距离。 控制器从传感装置附近通过的每个帧的电压信号产生单独的波形。 每个单独的波形是冲压装置的可移动部分的一个周期的位置的函数。 当多个独立的帧通过传感装置附近时,在控制器内产生多个单独的波形。 在控制器内比较波形以检测波形之间的偏差。 波形之间的偏差表示冲压装置内的薄片材料卡纸状况。 如果检测到薄片材料卡纸状况,则控制器向冲压装置提供信号以启动冲压装置的停止。 如果需要,也可以在控制器内比较多个单独的波形,以检测由冲压装置产生的框架或冲压件的构型与期望的框架或冲压构造的偏差。
