ABSTRACT:
A reel handler including at least one reel arm for engaging a reel is mounted on a frame. A moving device moves the reel arm to raise and lower the engaged reel, and a hydraulic motor for rotating the reel is contained within the end of the reel arm. The hydraulic motor includes a crank shaft operable to rotate the reel when the crank shaft is rotated. Preferably, two spaced reel arms are pivotally mounted on a transverse, telescoping support cylinder that allows the reel arms to be spaced at varying distances to accommodate reels of various sizes. At least two cylinder and piston assemblies are attached to the crank shaft for rotation of the crank shaft upon movement of each piston between a minimum and maximum point of travel in the cylinders. The two cylinders are offset with respect to each other such that each piston reaches its said minimum and maximum points of travel while the other is offset from its own said minimum point of travel. A valve assembly, driven by the crank shaft, provides hydraulic fluid to the cylinders under pressure to sequentially move each piston between its said minimum and maximum points of travel by providing hydraulic fluid under pressure on each piston in the desired direction of piston travel while evacuating hydraulic fluid under lesser pressure from the other side of the piston in its cylinder.
