Abstract
A winch mechanism is described that includes a motor, a drum mechanism, a winch line, and a hammer and anvil mechanism. The drum mechanism is connected to the motor, and the winch line is connected to the drum. The hammer and anvil mechanism is connected to the motor and the drum mechanism within the drum mechanism. The motor activates the hammer and anvil mechanism, and the hammer and anvil mechanism applies a percussive force to the drum mechanism as the drum winds up the winch line. In an alternative embodiment, the hammer and anvil mechanism is disposed around at least a portion of the drum mechanism.
