Abstract: A transport floor connected to the transport watercraft. An elevated drilling floor integrally connected to the transport floor; supporting a derrick comprising at least two rails for supporting a traveling top drive supported by a crown block. The crown block is connected to the derrick. The elevated drilling floor has a control panel comprising a power throttle for operating the top drive.

Abstract: A top drive power swivel assembly for well drilling rigs having a travelling frame for moving along a drilling tower. The travelling frame has at least two lower and two upper travelling frame extensions. A housing has at least two upper and two lower housing extensions each with an opening. A first connector penetrates openings of upper travelling frame extensions and openings of an upper housing extensions engaging the travelling frame to the housing. A second connector penetrates openings of lower travelling frame extensions and openings of lower housing extensions to securely engage the travelling frame to the housing. A top drive power swivel mounts to the housing and the top drive power swivel receives power from hydraulic motors. Various sheave assemblies mounted to the travelling frame engage a hoisting means. Guide wheel assemblies disposed on the travelling frame engage the tubulars.

Abstract: A top drive unit guiding system for aligning a power swivel and for dissipating torque created by the power swivel. The guiding system has a first guide frame and a second guide frame, where the first and second guide frames are located on opposite sides of the power swivel. Each guide frame includes at least two wheels. Each wheel is adapted to dissipate torque created by the power swivel and align the power swivel to support guide. Each wheel is made from a hard segmented rubber, a non-segmented rubber, a rubber composite, a synthetic rubber, or combinations thereof. The wheels are mounted to at least two adjustable brackets, where one bracket is associated with each wheel, and where each bracket positions the wheel in relation to the support guide.

Abstract: An automatic driller for controlling a rotating primary mover. The automatic driller has a manual brake handle. The manual brake handle has a stroke. A first elastic means applies a first tension to the manual brake handle. A swivel bracket is connected to the first elastic means. The first elastic means provides a first tension onto the swivel bracket.

Abstract: An apparatus that can be used during drilling operations for the purposes of clamping and holding drilling tubulars is disclosed. The embodiments relate to machinery that clamp and hold drilling tubulars to allow assembly to a specified torque or disassembly of the tubulars. The apparatus comprises a first grip with teeth inserts housed in a gripping block that opposes a second grip with teeth inserts housed in a second gripping block. The first and second grips are spaced and adapted to accommodate a range of diameters of drilling tubulars. Further, the gripping blocks are held by opposing arms connected to a driving means to create a tightening or loosening movement of the grips and maintain a certain orientation with regard to the tubulars.

Abstract: An earth drilling machine includes a mast, a crown block assembly mounted on the mast top for providing a drilling line having front sheaves, a fast line sheave mounted to a crown block sheave for reeving the drilling line, a drawworks drum, and a traveling frame assembly a midpoint of a width of a drawworks assembly aligned with the fast line sheave. The drawworks drum has a drum axis, the front sheaves are all aligned on a front axis, the fast line sheave and the deadline sheave are both aligned on a back axis, and the traveling sheaves are aligned on a traveling frame axis. The front axis, back axis, and traveling frame axis are parallel to the drum axis. The crown cross over sheave defines a cross over axis and the cross over axis is mounted perpendicular to the drum axis.
