The chain binder includes a lever body; a first side portion; a second side portion; and gears that effectuate two modes of operation. Namely, a power driven mode of operation or a manual lever mode of operation. Rotations of the gears causes hooks or connectors, via movement of eye-bolts, toward each other to place tension in the chains or strap. Opposite rotations of the gears causes hooks or connectors, via movement of eye-bolts, away from each other to relax the chains or strap. If components are damages during use, they may be replaced on an as-needed basis to reduce operational cost of the chain binder since the entire binder does not need replaced when only one component fails or is damaged.
