Abstract: A system that includes a first winch assembly having a first structure on which a fuel hose is configured to be spooled and unspooled, the first structure having a first rotational axis. The system also includes a second winch assembly located rearward of the first winch assembly, the second winch assembly includes a second structure on which a messenger line is configured to be spooled and unspooled, the second structure having a second rotational axis and being rotatable between first and second rotational positions. Upon the second structure being in the first rotational position the second rotational axis is non-orthogonal to the first rotational axis. Upon the second structure being in the second rotational position, the second rotational axis is orthogonal to the first rotational axis. The second structure including an axial through opening through which the fuel line is configured to pass when the second structure is in the second rotational position.

Abstract: A compensating hobbling assembly secures a set of elevators in a level position, while compensating for side or non-axial loading. An adjustable bail clamp is affixed to a bail, while an extendable hobble compensation assembly is pivotally attached to a set of elevators. A cable, chain or other flexible member having a finite length extends between the bail clamp and the hobble compensation assembly. Tension of said cable, chain or other flexible member can be adjusted so that the elevators are maintained in a substantially level position when suspended or hanging from bails. The hobble compensating assembly can extend, allowing the elevators to tilt and relative to the bails.

Abstract: A collar locating assembly ensures that that an elevator slip assembly does not engage against a pipe collar or coupling. An interlock system controls the operation of elevator slips, as well as related spider slips, in order to prevent unwanted simultaneous disengagement of both elevator and spider slips.
