TerrAdaptor Harken LokHead Winch Kit – Technical Rigging & Mechanical Advantage System

TerrAdaptor Harken LokHead Winch Kit: Technical Hauling and Personnel Hoisting Solution

Technical rescue teams, industrial rope access technicians, and confined space response units encounter severe operational challenges when executing vertical personnel hoists or heavy material hauls in complex, edge-bound environments. Traditional block-and-tackle mechanical advantage systems require significant rope lengths, introduce friction losses across multiple sheaves, and demand extensive reset cycles during deep pit or high-angle evacuations.

The TerrAdaptor Harken LokHead Winch Kit resolves these mechanical hauling bottlenecks by providing a self-tailing, high-efficiency winching system designed to integrate directly onto the TerrAdaptor Portable Anchor System leg segments. Engineered in collaboration with Harken Industrial, this lightweight, portable winch unit allows operators to switch seamlessly between 40:1 and 13.5:1 power ratios depending on load dynamics and lifting speed requirements. Its integrated braking mechanism automatically locks the line in the event of operator release, safeguarding personnel during critical vertical transit.

Key Benefits:

• Dual-Speed Mechanical Advantage: Delivers 13.5:1 and 40:1 gear ratios to balance hauling speed with minimal manual effort during heavy personnel or equipment lifts.
• Self-Tailing LokHead Capstan: Automatically holds tension on the line, allowing a single technician to operate the winch efficiently without requiring a secondary tailer.
• Seamless TerrAdaptor Integration: Custom-contoured mounting plate secures directly to TerrAdaptor leg segments using quick-release ball lock pins for rapid field assembly.
• Unlimited Rope Length Capacity: Capstan design allows continuous hauling over unrestricted rope lengths, overcoming the height limitations of traditional pulley systems.
• Automatic Load Capture Security: Built-in mechanical brake instantly locks the rope if handle rotation stops or is inadvertently released during hoisting.
• Versatile Textile Rope Compatibility: Fully rated for use with low-stretch Kernmantle and technical synthetic rope diameters ranging from 8 mm to 12.7 mm.
