Bullwheel tensioner systems and devices

A bullwheel tensioner system comprising:

• a chassis;
• a reel carrier assembly attached to the chassis and configured to support a reel having an electrical utility line disposed thereon, the reel carrier assembly comprising:
• a reel carrier frame;
• a reel shaft supported by the reel carrier frame, the reel shaft comprising a slot formed therein;
• a drive bar slidably attached to the reel shaft, the drive bar having a key configured to extend into the slot formed in the reel shaft;
• a clamp slidably attached to the reel shaft, the clamp configured to couple to the reel shaft such that the clamp prevents a reel supported by the reel shaft from sliding axially along the reel shaft;
• a fairlead assembly attached to the chassis and configured to receive the electrical utility line;
• and
• a bullwheel assembly, the bullwheel assembly comprising:
• a wheel configured to rotate about a central axis extending through a center of the wheel;
• a central hub assembly attached to the wheel proximate the center of the wheel, the central hub assembly being configured to permit the wheel to rotate about the central axis;
• a shaft in mechanical communication with the central hub assembly and configured to support the central hub assembly;
• a bullwheel support frame attached to the chassis and in mechanical communication with the shaft, the bullwheel support frame being configured to support the shaft;
• a plurality of removeable liners attached to the wheel and disposed along an outer circumferential surface of the wheel, each removeable liner of the plurality of removeable liners having a groove formed therein, the groove being configured to receive and support a first electrical utility line having an outer diameter of approximately 0.5 inches and a second electrical utility line having an outer diameter of approximately 1.2 inches.
