The second frame forms a rectangular trough having an open upper end. An upwardly opening cradle rests in the open upper end of the rectangular tough of the second frame that supports the pipe or the piece of earth boring equipment. A first vertical sack mechanism is attached to a first end of the first frame and a first end of the second frame. A second vertical jack mechanism is attached to a second end of the first frame and a second end of the second frame. The first and second vertical jack mechanisms raise and lower the second frame and the upwardly opening cradle supporting the pipe or the earth boring equipment to a desired position.Type: GrantFiled: April 15, 2013Date of Patent: July 15, 2014Assignee: MPC Bedrock Montana LLCInventor: Michael J.

Patent number: 8764344Abstract: A method for laying a pipe includes predisposing first and second releasable gripping devices for firmly gripping or releasing the pipe. The gripping devices are located along the longitudinal direction of the pipe. The gripping devices when activated grip and move the pipe so that only a predetermined longitudinal pipe section is received in the laying site. The gripping devices are rearranged and activated, instant by instant, so that the pipe is at all times solidly gripped by at least one gripping device. The above step is repeated until multiple longitudinal sections are housed in the laying site. A machine for laying pipe has gripping devices independently activatable for firmly gripping or releasing the pipe and also for moving the first and/or second gripping devices a predetermined number of times while gripping the pipe, for moving multiple longitudinal pipe sections into the laying site.Type: GrantFiled: September 16, 2010Date of Patent: July 1, 2014Assignee: Enereco S.p.A.Inventors: Aurelio Simoncelli, Giuliano Ciaroni

Patent number: 8727666Abstract: A pipeline insertion system (100) may include an insertion device (102) outside a tunnel that includes an insertion device frame (104) and a movable clamp device (106) in slidable engagement with the insertion device frame. A drive may cause the movable clamp device engaged with a pipeline to move between a first position (108) and a second position (110) along the frame. Inside the tunnel, the system may also include a plurality of support frames (118) remote from the insertion device and remote from each other which support the pipeline on bearings as the pipeline is pushed (or pulled) by the insertion device through the bores of a plurality of housing segments (122) mounted in the tunnel. A controller (126) is operative to control the drive and the movable clamp device responsive to transducers which measure pipeline slippage, thrust force, and clamping pressure.Type: GrantFiled: May 27, 2011Date of Patent: May 20, 2014Assignee: Brasfond USA Corp.Inventors: E.

Publication number: 20140119835Abstract: A casing puller includes a body and at least one arm. The body has first and second ends, at least one end connectable to a drill pipe. The body defines a longitudinal axis and sized for insertion into a casing pipe. The at least one arm is disposed on the body and moves between a stowed position and a deployed position. The at least one arm extends away from the longitudinal axis when in its deployed position and is arranged to engage an arm receiver defined by the casing pipe.Type: ApplicationFiled: October 25, 2012Publication date: May 1, 2014Applicant: SOUTHEAST DIRECTIONAL DRILLING, LLCInventor: John M.

Patent number: 8702349Abstract: Apparatus for replacing underground pipe is described, including a resistance plate from which a pair of hydraulic cylinders extend perpendicularly in parallel with each other. The cylinders operate cyclically with a pulling bridge having a cable gripper to provide a sequence of pulling strokes to a cable pulling a mole. The mole pulls a replacement pipe behind it through the old pipe, which has been burst, slit, or otherwise expanded by the mole. The resistance plate is provided with a slot, and the cylinders are positions such as to allow the mode to be pulled substantially completely into the apparatus. A holding bridge is releasably mounted spanning the slot in the reaction plate to position a second cable gripper for holding the cable on return stroke of the pulling bridge. The holding bridge may be removed at the end of the pulling operation to accommodate the mole.Type: GrantFiled: December 2, 2011Date of Patent: April 22, 2014Assignee: Tric Tools, Inc.Inventors: Robert Ward Carter, Robert Ding
