    Abstract: A pipe lifter for carrying one or more pipes including a slidably extendable elongate member and two sets of two laterally extending arms on each side of the elongate member. Each set of the two laterally extending arms are opposed to each other. Each of the laterally extending arms is pivotally fixed to the elongate member and moveable between a folded position where the arm is adjacent and parallel with the elongate member and an operational position where the arm extends laterally substantially at ninety degrees with respect to the elongate member. There are two or more L-shaped support members attachable to the laterally extending arms. There is also a hydraulic or pneumatic ram operationally configured to extend and shorten the length of the elongate member. In use, the L-shaped support members attached to the opposing laterally extending arms are positioned to be substantially opposing each other and the length of the elongate member is adjusted so that the outwardly extending section of the L-shaped support pipe is locatable within each open end of the pipe to secure the pipe to the pipe lifter.

    Abstract: A pullhead includes a housing that has a first end and a second end. The housing is separable between a first body and a second body. The first and second bodies are pivotally coupled at a joint and the first and second bodies together define an interior pocket of the housing. The interior pocket has an interior pocket width. The pullhead head includes a pulling feature at the first end. The interior pocket includes an interior retainer flange that has an inner width and is disposed within the interior pocket. The inner width is less than the interior pocket width. The first body and second body are pivotable relative to each other around an axis at the joint that is transverse to a pulling direction.

    Abstract: A poly pipe installation device constructed from a frame supporting a trenching tool for making a trench with side berms, a pipe roll supporting axles for a poly pipe roll so that the roll can be unwound to place the poly pipe into the trench. The poly pipe roll unrolls the pipe past a guide and under a wheel to position the pipe in the trench where it then partially buried with dirt drug off of the berms with angled drag chains. The poly pipe roll being unrolled is one of up to four rolls that are supported off of a horizontal turntable rotates each roll into the unrolling position and that also supports and stores multiple pipe rolls so that long runs of pipe can be laid quickly.
