| 20090003974 | TRANSPORT ASSEMBLY - A transport assembly configured to be attached to downhole apparatus has a support assembly configured to be attached to the downhole apparatus and a ground engaging assembly, which in one embodiment is a roller wheel configured to contact with and move in relation to a surface of a wellbore. The roller wheel may engage with the support assembly so as to provide for their relative rotation. In this embodiment, the transport assembly also includes a retaining member disposed between the roller wheel and the support assembly, and the retaining member is operable to resist separation of the roller wheel from the support assembly. The transport assembly is further configured such that, when the transport assembly is in use moving along a wellbore, the roller wheel bears against the retaining member, which in turn bears against the support assembly. In specific embodiments, the retaining member is a ball-bearing. | 01-01-2009 |
| 20100054895 | CASING AND ROD HANDLER - A casing pipe and drill rod handler for joining the drill rod in a casing pipe. A pipe sled is provided on a drilling rig, the pipe sled comprising an elongated track with a cart slidably mounted on the track to accommodate the casing pipe. A drill rod guide is provided at one end of the track to guide a drill rod as it is positioned and then inserted into the casing pipe. | 03-04-2010 |

| 20100303586 | PIPE STAND TRANSFER SYSTEMS AND METHODS - Methods and systems for transferring pipe (including tubulars such as casing, tubing, drill pipe, etc.) or stands of pipe from one location to another in a wellbore derrick, e.g. from a fingerboard to a well center. | 12-02-2010 |
| 20130011221 | APPARATUS FOR HANDLING TUBULARS - A method and apparatus for facilitating running or pulling tubulars from a well bore whereby the manual operations or functions normally performed by a human are undertaken by the THD and may including remote control or manipulation. The THD comprises an elevator assembly (THD) with a main body consisting of upper and lower plates, a scissor assembly and multiple sized die blocks to conform to the tubular diameter. The THD can be used as a transfer elevator to position the tubular for engagement by the make-up assembly, can be outfitted to perform as a safety clamp or restraining device and also configured as a tubular stabbing arm as required by the operation. | 01-10-2013 |

| 20140099175 | Alarm systems and methods for preventing improper lifting of tubular members - Systems and methods for preventing improper lifting of tubular members are described, in which sensing devices are used to detect when a tubular reaches a selected position within a lifting device suitable for engagement, and/or to detect when a lifting operation is initiated that would exceed the capacity of a lifting device. Operators are engaged with the tubular member and provided with a preselected force corresponding to the weight of one or more tubular members, such that when the weight of a lifting operation exceeds the preselected force, an audible device may be actuated responsive to sensor output, to immediately alert individuals, such that the improper lifting operation may be halted. Similarly, an audible device may be actuated responsive to sensor output when a tubular member reaches a selected position within the lifting device, such that additional movement may be ceased. | 04-10-2014 |
| 20140119855 | Pipe Handling Apparatus and Method - Equipment for moving tubular members from a storage rack to an elevated platform floor and back to the storage rack is disclosed. A base-mounted articulated support structure has a pipe trough mounted on top thereof. The support structure elevates the trough using a pair of struts and a plurality of articulated lifting arms mounted between the base and the support structure. Loading arms are secured to a side of the pivotal trough for picking up one tubular member from the rack and moving to the platform floor. Unloading arms detachably securable to the trough facilitate movement of the tubular members from the platform floor onto the rack. | 05-01-2014 |
| 20160032665 | APPARATUS FOR LIFTING AND/OR MOVING OPERATIONS OF DRILLING EQUIPMENT - An apparatus for lifting and/or moving operations of drilling equipment on a deck, the apparatus includes a load-bearing device, a synchronizing device, a synchronizing linkage comprising at least one guide which receives the synchronizing device, and a suspension device comprising at least one lifting arm. The at least one lifting arm comprises a first torque arm and a second torque arm. The first torque arm comprises a first end connected to the suspension device, and a second end connected to the synchronizing linkage so as to provide a first synchronizing link. The second torque arm comprises a first end connected to the synchronizing linkage so as to provide a second synchronizing link, and a second end connected to the load-bearing device. The first torque arm and the second torque arm are respectively further connected via the first synchronizing link and the second synchronizing link to the synchronizing device. | 02-04-2016 |
