| 175220000 | WITH ABOVE-GROUND GUIDE FOR RELATIVELY ADVANCING TOOL | 10 |
| 20080217069 | Auger boring machine with included pilot tube steering mechanism - An auger boring machine includes a common power source for powering a drive motor which rotates an auger and a drive assembly which drives a pilot tube to form a pilot hole in the earth which is followed by the auger. The drive assembly is movable into and out of the operational position of the auger to allow the auger to be mounted on the drive motor. Preferably the drive assembly is removably mounted on the frame of the auger boring machine. An electric generator and hydraulic pump are powered by the common power source for operating various components of the drive assembly. | 09-11-2008 |
| 20090008153 | AUGER STABILIZER - An auger stabilizer includes a rigid elongated body having a first end and a second end. The length of the body is adjustable between a retracted transport position and an extended drilling position. A pair of spaced apart wheels are attached at the second end of the body. A split body with two halves connected by fasteners is used to pivotally attach the first end of the body to a handle of an auger. When the body is in the extended drilling position, the pair of spaced apart wheels roll along a ground surface away from the auger as the handle of the auger descends and the pair of spaced apart wheels act to stabilize the handle of the auger against reactive torque. | 01-08-2009 |
| 20090166092 | PILE DRIVING - A system for aligning a pile during pile driving, comprising: a pile ( | 07-02-2009 |
| 20110011647 | Method And Separation Conduit For Handling Lubricant Mist, And Rock Drilling Rig - A method for handling lubricant mist used in mist lubrication, a separation conduit and a rock drilling rig having a mist lubrication system provided with a separation conduit. The return flow of the lubrication mist is conveyed in the separation conduit from the lubrication target to a collection container. The separation conduit is an elongated conduit having an elongated separation member arranged therein, the separation member comprising a plural number of successive and inclined barrier surfaces. Lubricant droplets contained in the lubricant mist hit the barrier surfaces and accumulate thereon. The separated lubricant is collected into the collection container at the outermost end of the separation conduit. | 01-20-2011 |
| 20110240371 | Drilling Station - In accordance with the invention, a drilling station or drilling rig, respectively, is provided for use on a drilling platform with a drilling mast, characterized in that the drilling mast and/or the energy supply and/or the generating device for hydraulic energy is/are composed of individual elements, the respective masses of which do not exceed a mass limit value of less than or equal to 25 t. A joining process requiring no welding, preferably by means of quick connectors, is preferred. | 10-06-2011 |
| 20100065336 | Top drive systems with main shaft deflecting sensing - A top drive system for wellbore operations, the top drive system including motor apparatus, a main shaft driven by the motor apparatus, and sensing apparatus for sensing bending of the main shaft; and, in certain aspects, the system providing information regarding the extent of main shaft bending and/or for warning an operator of an undesirable amount of main shaft bending. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b). | 03-18-2010 |
| 20120186882 | EARTH DRILLING MACHINE - A machine for the drilling of the ground includes a guide tower ( | 07-26-2012 |
| 20100326734 | DRILLING RIG ASSEMBLY METHOD AND APPARATUS - A method to assemble a drilling rig includes providing a base structure of the drilling rig, stacking a rig floor including a derrick on the base structure, actuating lifting cylinders to lift the rig floor above the base structure, inserting at least one first upper box between the base structure and the rig floor, and retracting the lifting cylinders to set the rig floor atop the at least one first upper box. | 12-30-2010 |
| 20120261195 | Tool Guide Device for a Drill Floor - A device is for vertical tool guiding for a drill floor. On the drill floor is arranged at least one rig. Each rig is arranged on a rig foundation supported on the drill floor rotatably about a first, vertical axis (A) and arranged to be able to displace a tool in a horizontal working sector (S | 10-18-2012 |
| 20130146364 | CENTRALISER - A centraliser for use in a rock drill rig is disclosed. The centraliser includes a clamping member which moves generally tangentially to a bush, in order to clamp the bush in place within the centraliser. | 06-13-2013 |
