Featured Product of the Month Custom Access Ramp Winch
Thern, Inc. designed and manufactured a customized helical worm gear winch that is being used to raise and lower a boat access ramp on a pier in Seal Beach, CA. The ramp allows access to boats used to ferry crews and equipment to offshore oil rigs. Thern’s unique 4HWF winch is outfitted with a secondary disc brake, a 4-pole rotary limit switch with an encoder needed to comply with the personnel-rating as the ramp remains suspended above pitching and rolling vessels while people are boarding and offboarding. The winch also features a line speed indicator with alarm, an emergency stop button, 5 radio remote controllers and was Epoxy painted to resist corrosion in the harsh marine environment.
