An internal shaft reinforces the tubular drum against crushing from long, heavy well access lines, extending service life and lowering replacements.

Using a hand drill to drive a capstan, this case shows a portable way to spool pull string and reduce strain during cable installation.

Automatic coordination of winch, steering, braking, and powertrain control helps recover vehicles from low-traction conditions without extra personnel.

A frame-and-winch hitch keeps low-clearance EVs away from the water while enabling controlled watercraft launch and retrieval.

A two-piece bumper with a releasable impact member improves off-road protection, sensor integration, and accessory access while limiting weight.

A drill-driven capstan puller spools and unspools pull strings to cut operator strain and avoid bulky cable pulling machinery.

A motor-driven capstan and feedback-based tension control speed cable pulling through conduits while reducing strain and improving handling.

A distal-end pulley doubles cable pull per stroke, reducing stretch and simplifying pipe bursting with a single gripping mechanism.

A pivoting boom and tow-hitch frame let one person lift, store, and transport heavy removable convertible tops away from home.

A hybrid puller-tensioner switches between engine, generator, and battery power to deliver quiet operation without losing torque in remote use.

A swiveling winch arm uses hydraulic counter-torque and selectable modes to offset cable-induced yaw and keep ski groomers aligned.

A feet-up hidden winch behind the bumper uses a viewing window and underbody access panel to preserve aerodynamics while keeping the line visible.

Complementary bolt patterns replace improvised or welded winch mounts, improving alignment, attachment strength, and installation flexibility.

A crushable fairlead bracket lets the winch hook deflect into the bumper during impact, avoiding sensor calibration and test disruption.

A motor-driven gripping adapter modulates tailing force from motor current and speed feedback to prevent slip or binding and protect cables.

Motor current feedback adjusts tailing force in real time to prevent slip or binding and keep cable pulling speed consistent.

A standardized modular winch uses rotatable motor, gearbox, and fairlead modules to fit varied vehicle mounting layouts and simplify manufacturing.

A two-piece winch shell shields the buffer member from impact and abrasion while allowing easy access and lower-cost replacement.

A rotating boom with alignable arms lets the puller reach conduits at different heights and work through tight spaces more easily.

An inward-sloped drum face guides push-cable winding in pipe inspection reels to reduce wear, user effort, and cable jump-out.

Handle offset rate detection triggers crane deceleration stopping, cutting driver reaction demands and avoiding harsh brake impact.

A ratchet-sleeved spool connection replaces welding to simplify winch assembly, improve alignment, and maintain stable operation.

Interpolated force and torque curves create a correction coefficient that improves actuation torque accuracy without separate motor or gearbox calibration.

A brake with torque that drops as cable layers build up keeps winch cable force consistent and helps prevent cable and equipment damage.

Elastomer damping rings and a hollow output shaft create a compact cable drum drive that absorbs rod-borne shock loads and protects the gear motor.

A hydraulic bypass links the winch pressure lines to stop braking pressure buildup, preventing overload when the spring brake is applied.

A housing-mounted hoist with sheaves and a motor rotates journal and grinding parts through a service opening, cutting crane use, time, and cost.

A sliding weight and rope-mounted detector stop over-lifting on wire rope hoists without structural changes or hoist disassembly.

Magnetic attachment keeps a detached rope-guide shell fixed to the vehicle body, preventing loss while protecting the winch guide.

A reciprocating rope guide and stationary roller keep wire rope winding neat, reducing jamming, stacking, tangling, and rope damage.

A fairlead tail chain support secures mooring line sections for ROV cutting and reconnection, reducing catenary weight and chain twisting.

Current, runtime, and temperature monitoring trigger relay cutoff before excess heat damages a winch motor or causes combustion risk.

Nonlinear load analysis checks contact points, strain, deflection, and clearance so a winch hook retention design avoids retraction damage.

An offset attachment aperture creates a cam surface that stops winch ring rotation, reducing shackle friction, heat, and wear.

A cam-driven dual-pawl lock controls spool rotation during trailer loading, improving secure attachment while reducing wear.

A movable rope securing member detects incorrect reeving at the deflection roller and alerts operators before rope or boom-head damage occurs.

A weighted oscillating arm keeps the hoist rope pressed to the drum across boom angles, preventing irregular winding and rope wear.

A one-way bearing with disc spring resistance lets the winch wind freely yet restrains reverse reel speed to prevent rapid cable release.

Supercapacitor energy recovery lets a mobile electric heave compensator stabilize loads without external power or complex passive systems.

A deformable grooved wrap protects wire rope during repeated drum winding, reducing interlayer pressure, damage, and drum space demands.

Supercapacitor energy buffering gives electric heave compensation near-instant force control while avoiding gas spring leakage and maintenance.

Asymmetrically placed winch drum ribs maintain line grip while reducing wear, jerks, and slippage during high-load release and uptake.

Different payout and retraction speeds let a towbarless tractor capture aircraft nose gear faster while maintaining controlled handling.

Automatic winch strap retraction and brake lockout prevent strap movement damage when a towbarless tractor captures and tows aircraft nose gear.

External operator controls, winch retraction, and nose-gear sensing let crews monitor capture clearly and stop the tractor at cradle engagement.

Visual monitoring on a towbarless tractor records capture events and misalignment to help diagnose aircraft nose gear damage.

A motor-driven planetary gear reset returns the winch engaging switch to lock automatically, avoiding manual toggling from a distance.

Sensors and a motorized lateral fairlead adjust rope entry angle in real time to keep winch drum winding uniform on uneven ground.

Adaptive control filtering shifts attenuation by resonance and operating mode to suppress load swing without sacrificing crane operability.

An elastomeric polymer ring replaces metal springs in a hoist pulley to distribute pressure evenly across cables, reducing maintenance frequency.
