Abstract: The combination of a power driven pipe tong and a backup tong is supported upon a hoist mechanism to be positioned vertically with respect to the tool joints of a string of drill pipe. A magnetic eddy current detector is disposed adjacent to the drill pipe and produces a command signal to control the hoist mechanism and stop motion when the tong assembly is in a position at which the tool joint engaging jaws of the power tong and the backup tong are properly engageable with the tool joints.
Abstract translation: 动力驱动管钳和支撑钳的组合被支撑在提升机构上，以相对于钻杆串的工具接头垂直定位。 一个磁涡流检测器被设置成与钻杆相邻，并产生一个命令信号来控制起重机构，并且当钳组件处于工具接头接合动力钳和备用钳的夹爪适当位置时停止运动 可与工具接头接合。

Abstract: A pipe position indicator for pipe rackers, in which the position of a stand of pipe is shown for each of two axes on a pair of dials, one of which dials shows gross positioning and the other of which dials shows fine positioning, with respect to the well centerline and the racked positioned of the pipe stand.
