Winching basics

A winch is a powered drum that winds in rope or cable to pull a vehicle. Most four-wheel-drive winches are electric, powered by the vehicle's battery, and mounted on the front bull bar or a cradle. Unlike a kinetic recovery, a winch pulls slowly and steadily, giving you fine control. And because you can anchor to a tree, rock or ground anchor, a winch lets you recover yourself without another vehicle.

Winching is safer than snatching in many situations, but the forces involved are still enormous. This guide covers the basics. As with all recovery, hands-on training is essential.

How a winch works

An electric motor drives a drum through a gearbox, winding rope onto the drum. A brake holds the load when the motor stops. A clutch lets you free-spool the drum to pull rope out by hand. The winch is controlled by a remote, wired or wireless, so the operator can stand clear.

Winches are rated by their maximum pulling capacity, usually measured on the first layer of rope on the drum. As more layers wind on, the effective diameter of the drum increases and the pulling power decreases. That's one reason to spool out plenty of rope before a hard pull.

Choosing a winch

Consider:

• Rated capacity. Choose a winch suitable for your vehicle's loaded weight, following the manufacturer's guidance. Heavier touring vehicles need more capacity.
• Rope type. Synthetic or steel (see below).
• Mounting. The winch must be mounted on a winch-compatible bull bar or cradle bolted to the chassis. Check compatibility with airbags, driver-assistance sensors and cooling airflow.
• Electrical supply. Electric winches draw very high current, so heavy cabling, a good battery and an isolator or circuit breaker are needed. See our dual battery systems guide.
• Water resistance and quality. Look for sealed motors and controls and good after-sales support.
• Weight. A winch and compatible bar add significant weight to the front axle.

Steel cable or synthetic rope

Synthetic rope is made from high-strength fibres such as Dyneema. It is much lighter than steel, easier on the hands, floats and stores less energy, so it is less violent if it breaks. It needs protection from abrasion, sharp edges and heat, and should be used with a hawse fairlead rather than rollers.

Steel cable resists abrasion and is cheaper, but it is heavy, can kink and develop sharp broken strands, and stores more energy. It is used with a roller fairlead. Always wear gloves when handling steel cable.

Essential winch accessories

• Gloves to protect your hands.
• Tree trunk protector to protect trees and the rope when anchoring to a tree.
• Winch extension strap to reach distant anchors without spooling out all the rope.
• Snatch block to double the line or change the direction of pull.
• Rated shackles to connect components.
• Dampener placed over the rope during every pull.
• Ground anchor for areas with no natural anchors.
• Equaliser strap for spreading load between two points.

Choosing an anchor

The anchor must be stronger than the forces involved. Good anchors include large, healthy, well-rooted trees, used with a tree trunk protector placed low on the trunk; another vehicle, braked and chocked; a buried spare wheel or purpose-made ground anchor; and large, solid rocks. Never anchor to small, dead or shallow-rooted trees.

A safe winching process

1. Assess. Work out the direction of recovery and possible anchors. Clear obstacles.
2. Prepare. Wear gloves. Free-spool the rope and walk it to the anchor, keeping it off sharp edges. Leave at least a few wraps on the drum.
3. Rig. Fit the tree trunk protector or anchor strap and connect with a rated shackle. Use a snatch block for a double line if needed.
4. Dampen. Place a dampener over the rope.
5. Clear the area. Keep bystanders well away, ideally at least one and a half times the length of the rope out, and never stand in line with the rope or step over it.
6. Take up slack. Gently wind in until the rope is just taut, then check everything.
7. Winch. The vehicle being recovered should be in neutral or a low gear with the driver helping gently, engine running. Winch in short bursts to avoid overheating the motor.
8. Spool neatly. After the recovery, rewind the rope evenly under light tension so it doesn't bury into lower layers on the next pull.

Common winching techniques

Double line pull. Running the rope from the winch through a snatch block at the anchor and back to a recovery point on the vehicle roughly doubles the pulling force and halves the speed, reducing strain on the winch.

Redirected pull. Using a snatch block attached to an anchor at an angle lets you pull in a direction where there's no anchor straight ahead.

Winch maintenance

Inspect your rope or cable regularly and replace it if it's frayed, cut, kinked, flattened, melted or heavily abraded. Operate the winch occasionally to keep it working. After water crossings or muddy trips, check for water ingress, clean the rope and respool it under light tension. Check electrical connections and the remote.

Using a winch for others

Your winch can help others, but rig it carefully, check their recovery points and anchor your own vehicle securely, braked and chocked. Don't exceed your winch's or rope's capacity.

Battery care while winching

Electric winches draw heavy current, so keep the engine running during winching, rest the winch between pulls to let both battery and motor recover, and check battery health before remote trips. A flat battery deep in a bog hole is a hard lesson. If you have a dual battery system, check how your winch is wired and which battery it draws from.

Common mistakes

• Anchoring to a small or dead tree.
• Standing in line with or stepping over a loaded rope.
• Winching with the engine off and flattening the battery.
• Pulling from the last layer of rope on the drum.
• Respooling loosely so the rope buries itself next time.

Winching on slopes

Winching up or down steep slopes needs extra care. Keep the vehicle straight, use the brakes and engine braking as directed, and never let the rope go slack under load on a descent.

Key points

A winch allows slow, controlled recoveries and self-recovery. Choose a suitable capacity and mounting, consider synthetic rope, carry essential accessories, use strong anchors, fit a dampener, keep bystanders clear, run the engine and look after the rope.
