Portable Backpack Underwater Cable Winch | Manual Tether Reel for ROV & Subsea Operations
Portable Backpack Underwater Cable Winch | Manual Tether Reel for ROV & Subsea Operations
The Portable Backpack Underwater Cable Winch is a rugged, ultra-mobile manual tether management system engineered specifically for demanding field expeditions, nearshore marine operations, and subsea inspection deployments. Featuring an innovative 3-in-1 deployment architecture (Backpack, Hand-Carry, and Ground-Mount), it eliminates the bulk, high weight, and transport constraints of conventional electric or heavy-frame winches—giving oceanographers, ROV pilots, and field engineers true single-operator mobility across rugged shorelines, coastal rocks, small boats, and mountainous terrains.
Key Engineering Highlights
- 3-in-1 Versatile Deployment: Outfitted with heavy-duty ergonomic padded backpack straps for effortless single-person transport up slopes, over embankments, or onboard small vessels. Integrated wide-stance base feet provide solid ground stability for hands-free winding and unwinding on site.
- Automatic Level-Wind Mechanism: Integrated bidirectional automatic spooling guide ensures neat, uniform cable layering during retrieval. It effectively eliminates cable crisscrossing, pinching, and sharp-bend stress, safeguarding expensive ROV neutral-buoyancy tethers and fragile subsea optical fibers.
- Instant Position Lock & Friction Brake: Equipped with a dependable mechanical brake and lock mechanism. Operators can pause payout or lock the spool at any desired depth or distance, preventing unwanted freewheeling, cable slippage, and tether runaway.

Marine-Grade Anti-Corrosion Configurations:
- Q235 Carbon Steel: Protective coated for inland lakes, freshwater hydrological stations, and standard outdoor fieldwork.
- 304 Stainless Steel: Enhanced corrosion resistance for damp field environments, river basins, and splash zones.
- 316L Marine Stainless Steel: Maximum resistance against saltwater pitting, ocean spray, and continuous marine atmosphere.
- Spool & Sprocket: CNC skeletonized aluminum alloy (AL) for maximum structural strength with minimal weight.
- Shafts & Fasteners: High-grade 304 or 316 stainless steel hardware throughout.
- Smooth Low-Resistance Drive & Foldable Crank: Precision low-friction sealed bearings ensure light, fatigue-free manual winding even with extended tether lengths. The folding crank handle locks securely during payout and folds flat against the frame for snag-free packing and transit.
- Modular OEM / ODM Customization: Available with custom drum diameters, core widths, slip ring integrations, and pre-terminated subsea watertight connectors to fit specific project requirements.
Typical Applications
- ROV / AUV Operations: Tether deployment and retrieval for observation-class ROVs, underwater cameras, and acoustic sensors.
- Marine & Coastal Surveys: Nearshore environmental monitoring, pier and wharf inspection, dockside water sampling, and offshore engineering.
- Hydrology & Dam Inspection: Riverbed surveying, reservoir monitoring, culvert inspection, and hydrological flow meter deployment.
- Emergency Field Communications: Rapid layout and recovery of tactical fiber-optic cables and communication lines across rugged hills and wilderness.
