ABSTRACT:
A cable reel handler device, including a slide base on a vehicle having channels aligned transverse to the length of the vehicle. A pair of movable carriages provide lateral movement in the channels via hydraulic cylinders. Lifting arms mounted respectively on the carriages extend out to engage a reel, and have an extensible torsion bar shaft to maintain a fixed alignment. Hydraulic lift cylinders move the lifting arms in unison to move a reel to and from the vehicle and in position for winding and unwinding cable on the reel. Hydraulic motors rotate the reel for winding and unwinding cable. A source of hydraulic fluid is operably connected to all the hydraulic devices.
