Abstract: A drilling machine is disclosed. The drilling machine may include a mast and a machine frame. The mast may include a mast frame, a movable drill head assembly, a first pivot aperture, and a plurality of first lock apertures each corresponding to a different drilling position of the mast. The machine frame may include an engine, a ground engaging assembly having an axle, and a mast coupling assembly having at least a pair of opposed legs, each leg including at least one plate. The at least one plate of each leg may include a second pivot aperture positioned to align with the first pivot aperture to pivotably couple the mast to each leg. The at least one plate may also include a second lock aperture positioned to align with each of the first lock apertures and receive a lock pin for locking the mast in a drilling position.

Abstract: A rig system includes a first base box and a second base box extending parallel to and offset from the first base box, such that an open space is defined therebetween. A rig floor is connected to the first and second base boxes and spans the open space. A mast is coupled to the rig floor. A rig-raising system is configured to raise the rig floor vertically above the ground. A combined local equipment room (LER) and drilling control room (DCR) skid is connected to the rig floor and configured to be raised with the rig floor. A reel skid is positioned at least partially vertically below the LER/DCR skid. A setback structure extends between the first and second base boxes and blocks the open space on at least one end.

Abstract: The present invention discloses a high-capacity drilling rig system that includes novel design features that alone and more particularly in combination facilitate a fast rig-up and rig-down with a single set of raising cylinders and maintains transportability features. In particular, a transport trailer is disclosed having a first support member and a drive member which align the lower mast portion with inclined rig floor ramps and translate the lower mast legs up the ramps and into alignment for connection. A pair of wing brackets is pivotally deployed from within the lower mast width for connection to the raising cylinder for raising the mast from a horizontal position into a vertical position. A cantilever is pivotally deployed from beneath the rig floor to a position above it for connection to the raising cylinder for raising the substructure from a collapsed position into the erect position.

Abstract: A mast assembly that includes a mast and a hydraulic circuit for moving the mast. The hydraulic circuit includes a primary hydraulic cylinder coupled to the mast to rotate the mast about a pivot axis and a secondary hydraulic cylinder extending from a rod end to a cap end that is fluidly coupled to the primary hydraulic cylinder. A directional valve is fluidly coupled between the primary hydraulic cylinder and secondary hydraulic cylinder to keep a pressure on the cap end of the secondary hydraulic cylinder greater than the pressure on the rod end of the secondary hydraulic cylinder during all operating conditions.

Abstract: A system and method are used for transporting a plurality of tower sections of a wind turbine on beds of transport devices, such as flat railcars. Supports affix at support locations on beds to accommodate at least one of the tower sections on each of the transport devices. The supports can include bed supports, such as tabs, extending from the beds, and can include cradle supports with slots that engage on the tabs. A circumferential dimension of a cradle is adjusted on each of the supports against which the tower section rests. Each of the tower sections is then supported with at least two of the supports by loading the tower sections on the transport devices. An end of each of the tower sections is then affixed to a flange on at least one of the supports on each of the transport devices.

Abstract: A portable tower trailer having a light tower housing constructed to allow for both stacking and nesting which is beneficial in both storage and shipping of light towers is disclosed. The portable tower trailer employs a frame having a hinged axle that allows the wheels to operate in a conventional manner. The hinged axle further allows the wheels to be rotated upward allowing the frame to rest flush on the ground or stacked upon a similar shaped portable tower. The stackable light tower is constructed having a base employing an engine system and a fuel tank; and a mast pivotally coupled to the base and movable between a storage configuration and a positioning configuration. The storage configuration is when the mast is folded over an upper surface of the base whereby an additional light tower base or tower trailer may be placed or stacked over the top of the first light tower base.
