A lifting arm arrangement includes a gripper head arm, a lifting arm, and a lifting cylinder. A gripper head is fastened to a first gripper head arm end. A first lifting arm end is pivotally connected to the gripper head arm. A second lifting arm end is pivotally connected to a stationary lifting cylinder part. A second gripper head arm end is pivotally connected to a movable lifting cylinder part. The stationary lifting cylinder part comprises a cylinder with a cylinder cavity having first and second cylinder openings. A piston rod with a piston is arranged in the cylinder cavity. A first piston rod portion projects from a first piston end of the piston. A second piston rod portion projects from an opposite second piston end of the piston. Working areas of the first and second piston ends are substantially equal to each other.

A guide arm with dual guiding functionality is disclosed. The guide arm comprises two parallelogram mechanisms with a slew drive in between. The first parallelogram mechanism may move the guide arm between different travel positions. The slew drive may rotate the second parallelogram mechanism between different clock positions. The second parallelogram mechanism may extend and retract the guide arm. The guide arm may be mounted to a belly board or to a derrick wall rather than on a drill floor. A first guiding functionality may include guiding the lower end of a pipe stand in transfer between a drilling rig well center and a storage position. A second guiding functionality may include guiding the pin end of a single tubular between a drilling operation and a catwalk.

A storage system for storing elongate tubulars includes a base with a drive and a setback area for a vertical support of the elongate tubulars, an elongate column mounted on the base, and a first fingerboard assembly arranged on the elongate column. The base rotates about a vertical axis via the drive. The first fingerboard assembly includes at least one fingerboard. Each of the at least one fingerboard includes a plurality of storage slots arranged in a parallel, side-by-side configuration. Each of the plurality of storage slots receives a plurality of the elongate tubulars.

Methods are disclosed for handling cylindrical tubulars in a process that, in preferred embodiments, also performs cleaning, inspection and other operations on the tubular. The tubular is held stationary while it is rotated. During rotation of the tubular, internal and external cleaning systems, and data acquisition systems, pass up and down the length of the rotating tubular. In preferred embodiments, a first tubular is loaded onto the handling machine, whereupon it is indexed and then rotated. Cleaning, inspection and other operations may be performed during rotation. Once operations are complete, the handling system ejects the first tubular while queuing up a second tubular to be loaded.

The invention provides a compact pipe handling trailer for a drilling or service rig. The pipe handling trailer includes a deck having a raised frame and an extended horizontal frame. A trough is pivotally housed within the extended horizontal frame, the trough having a first end and a second end. A first piston/cylinder assembly is operably coupled to the first end of the trough; a second piston/cylinder assembly is operably coupled proximal to the second end of the trough. An operating means for the pipe handling trailer is provided within the raised frame of the deck. The pipe handling trailer is transportable and is attached to a trailer on a common axle. A number of retractable downriggers are provided on the deck to position the pipe handling trailer firmly to the ground.

Embodiments disclosed herein generally relate to a catwalk and, more specifically, to a crawler assembly for a catwalk. The catwalk includes a frame and a crawler having a plurality of leg assemblies coupled to the frame. The frame defines an interior volume of the catwalk. Each leg assembly includes a vertical leg component, a foot component, and a horizontal leg component. The foot component is coupled to the vertical leg component. The vertical leg component is configured to actuate the foot component in a vertical direction. The horizontal leg component is coupled to the vertical leg component. The horizontal leg component is configured to actuate the foot component between a stowed position substantially within the interior volume and an extended position substantially outside the interior volume.
