Cable-line Safety System: Electro/hydraulic Emergency Stop Device for a Winch, Drum or Capstan


This CDC-developed invention entails a system of electrical and hydraulic circuits used to stop a rotating winch in an emergency. Amongst other locations, one stop switch can be positioned on a capstan winch horn. This location makes it available to a victim entangled in rope being retrieved on a gypsy drum. As designed, the stop circuit could be used with an electrically, hydraulically or pneumatically operated winch. A variant of this safety system has been successfully tested on a purse seining fishing vessel in Alaskan waters.

Potential Commercial Applications: Competitive Advantages:
  • Retrofitting existing winches for additional safety and adherence to possible future regulations
  • Specifically designed and tested for the marine/fishing industries
  • Applications in mining, construction, forestry, and/or off-road automotive industries
  • Workers' well-being concern groups
  • Insurers of fishing vessels; also mining, construction and forestry operations
  • Manufacturers of cable reel trailers and wire-drawing machinery
 
  • Complies with numerous international safety regulations requiring winches, drums and capstans to have a master on/off switch in easy reach for worker safety
  • Can be packaged as a ‘retrofit kit’ for integration with current commercial winch/drum usage


Development Stage:
  • In situ data available (on-site)
  • Prototype
