摘要： A system includes a hoist drive mechanism that elevates and lowers a load hook from a boom and a detector that provides obstacle location and identification information. A processor receives the obstacle location and identification information from the detector and provides obstacle avoidance data in response thereto.

摘要： A rotary table drive with a top plate and a bottom plate cooperating to define a bore and an adjacent sealed gear housing. A bushing adapter passes through the bore and is configured to receive a bushing to mate with a segment of polygonal drill pipe allowing rotational motion to be imparted thereto. The device includes a ring bearing having an inner ring affixed rigidly to the bushing adapter and an outer ring rigidly affixed to the bottom plate, and a drive gear within the sealed gear housing mated to the bushing adapter such that the bushing adapter is rotated in response to rotation of the drive gear. The bearing is sealed against exposure to the elements by being surrounded on all sides by a combination of the top plate, bottom plate, and bushing adapter.
