Dutton-Lainson's 25215 StrongArm SA-Series 12V DC electric winch is used for vehicle or boat trailer use. Built to the same high quality standards as regular SA-Series StrongArm electric winches. This high-torque 12V DC motor has circuit-breaker overload protection. StrongArm DC electric winches have a dynamic motor brake as well as an automatic mechanical friction brake to securely hold the load. This electric winch features a 3,000 lb. load capacity for boats up to 9,000 lbs. Other features include: "power in", "power out", controlled freewheeling clutch, 20 ft. of a 2 in. wide extra heavy duty polyester strap and snap hook and an emergency crank handle in case of power loss. The clutch lever allows for smooth load control and easy cable removal. The winch is powered by your vehicle battery, using the included wiring harness (25 ft. of positive battery wire and 8' of ground wire). The 3-position rotary switch and clutch controls are conveniently located on the same side for easy operation. Note: This winch is built for horizontal pulling applications. For vertical lifting applications, order a winch with no clutch lever installed. This winch has a maximum run time of 4 minutes. See owner's manual for more details. All D-L StrongArm electric winches are built for multipurpose hauling and pulling operations. They are not to be used as hoists for lifting, supporting, or transporting people, or for handling loads over areas where people could be present.
