Top-mounted hoist for use in a derrick or drilling mast of an oil and gas rig
Embodiments of a top-mounted hoisting system include a single-layer winch drum located at an uppermost end of a derrick or drilling mast, a drill string handling tool, and one or more drill lines extending from the single layer winch drum to the drill string handling tool. The drill string handling tool may be a top drive. When the drill line is connected directly to the lifted load, the drill line experiences far less load cycles than when the line runs through crown and travelling blocks. If the drum diameter is large enough, cut-and-slip operations may be eliminated, and the drill line may be replaced at longer time intervals. Embodiments provide for lower weight and may provide lower cost as a result. The top-mounted drum does not take up any space on the drill floor and less total length of drill line is also required than if the drum was floor-mounted.
Trailer Bed Mounted Load Plow System
The present disclosure of the Trailer Bed Load Plow concerns a highly customizable, legacy trailer compatible, removable, system for unloading trailer loads and/or flat bed loads. The system, generally speaking, comprises a sled, a plow, a controllable puller such as a winch, guide rails, and an attachment point on the trailer. In some implementations, the plow and puller are attached to the sled, and the combined unit travels the length of the trailer bed, constrained by the guide rails to lateral travel, via the force created by the puller acting against the attachment point which is effectively positioned on an end of the trailer.
