Abstract: An electric contactor may include a first plunger member supporting a first contact member thereon, the first plunger member being movable between a disengaged position and an engaged position with respect to a first electrical terminal; a second plunger member supporting a second contact member thereon, the second plunger member being movable between a disengaged position and an engaged position with respect to a second electrical terminal; a first linear actuator selectively causing movement of the first plunger from the disengaged position to the engaged position; and a second linear actuator selectively causing movement of the second plunger from the disengaged position to the engaged position. Actuation of one of the first and second linear actuators will apply a weld breaking force against the plunger associated with the other of the first and second linear actuators.

Abstract: A winch may include a drum, a winch motor adapted to rotatably drive the drum in a first direction and a second direction, a cable adapted to be wound off of and onto the drum, and a fan including an impeller selectively driven by a fan motor. The fan is adapted to cool the winch motor.

Abstract: A compact lightweight air compressor is provided with a DC motor to provide versatile use in the field where no AC power source is available. The air compressor includes a intercooler storage vessel for cooling and storing the compressed air as well as a cooling fan arrangement that allows cooling of all the air compressor components.
