Special Features: Allied Power Products, Inc. (APPI) recently produced this custom AC powered sonar recovery winch for use on the University of Hawaii’s newest ocean research vessel.

Why APPI: Although initially specified to be equipped with interchangeable drums to accommodate varying line sizes, APPI provided the university with an alternative single drum design that exceeded their requirements.

All aluminum construction of the AC electric winch protects it from corrosion and keeps the overall weight below the university’s requirements. Equipped with a 10 hp motor, the sonar winch has 3,900 pounds of line pull at a maximum line speed of 83 feet per minute on the first layer of line on the drum.

APPI’s proprietary AutoAdvance Line Spooler system assures proper spooling on the drum, which solves the fleet angle or bird-nesting. A variable frequency drive provides speed and torque control and digital display, protected within a NEMA 4x enclosure, meters line speed, wire rope distance, and load. The electrically released brake is spring applied with an optional manual override release.

The overall sonar recovery winch package is approximately 6 feet deep, 3.5 feet wide, and 6.5 feet tall. The drum will store over 4,300 feet of sonar cable or 1,900 feet of 5/8″ wire rope.
