Towing Winch (Custom, up to 125 t rated pull)

Wire rope / tow line inspection: Check for broken wires, kinks, corrosion, and wear; measure diameter at multiple points and compare against minimum allowable diameter; inspect end terminations (sockets, ferrules, splices).

Drum and spooling device inspection: Verify drum grooves for wear and deformation; check automatic spooling device alignment and traversing motion; inspect drum flanges and core for cracks.

Brake system inspection: Test automatic disc/band brake holding capacity under rated load; inspect brake lining/pad thickness and disc surface condition; verify fail-safe function (spring-applied, hydraulically released or equivalent).

Clutch inspection: Test friction clutch engagement and slipping torque; inspect clutch plates or cone surfaces for wear; verify quick-release function operation and hydraulic actuation if applicable.

Hydraulic system inspection (hydraulic drive units): Check HPU oil level, cleanliness (particle count), and filter condition; inspect hoses, fittings, and manifolds for leaks; verify pressure relief valve settings.

Structural and mounting inspection: Inspect bed plate, foundation bolts, and deck welds for cracks or corrosion; check bearing housings for play and lubrication; inspect paint coating condition and corrosion protection.

Control and instrumentation inspection: Test PLC controller, load cells, and drum encoder calibration; verify local and bridge control panel operation including touchscreen HMI; test all limit switches and overload protection relays.

Lubrication and sealing inspection: Verify oil-bath or grease-lubricated gearbox levels; inspect shaft seals for leakage; confirm lubrication intervals are met and correct lubricant grades are used.
