RUNVA Winch hook 5/16" - 3000 - 6800 lbs

Steel rope has long been the standard choice for winches. Made from multiple strands of carbon steel wire, it offers excellent resistance to abrasion and generally comes at a lower cost than synthetic alternatives. Its main drawback is the tendency for individual wires to break over time, creating sharp burrs – meaning gloves are essential for safe handling.

Synthetic ropes, introduced to the market much later, are dramatically lighter – often up to ten times lighter than steel. Despite the lower weight, they can be incredibly strong, with some models offering breaking strengths up to seven times higher than comparable steel ropes. An often-overlooked advantage is that synthetic rope floats on water, making it extremely useful during river crossings and wet off-road conditions.

Unlike steel, synthetic rope doesn’t snap violently. It’s more flexible, and if damaged, it can be repaired in the field simply by tying a knot. This makes it a much safer option to use. On the downside, synthetic ropes cost more and are more susceptible to abrasion. However, for those willing to invest, they offer unmatched convenience and performance in challenging terrain.

The answer is simple – the fewer wraps on the drum, the more pulling power the winch can deliver. The exact amount of rope you can fit depends on the drum size. For example, a standard 12,000 lbs winch can typically hold about 28 m of 10 mm cable, or around 25 m if you go up to 12 mm. With these lengths, you need to pay close attention to how the rope is spooled to avoid pushing apart the crossbars that support the winch’s legs.

A winch is just the starting point. To get the most out of it – and to ensure the safety of both your gear and everyone involved – it’s worth investing in a few key accessories.

1. Battery Isolator Switch (Kill Switch)
Allows you to quickly cut power to the winch, preventing accidental activation or electrical short circuits.

2. Snatch Block
Increases your winch’s pulling power and lets you change the pulling direction. Essential for angled pulls or when working with particularly heavy loads.

3. Tree Saver Strap
Protects the bark and structure of a tree when it’s used as an anchor point.

4. Shackles and Thimbles
Strong connection points for attaching the rope to straps, hooks, or other recovery gear. Opt for high-quality steel or aluminum models with certified load ratings.

5. Protective Gloves
An absolute must for working with steel cable, and highly recommended for synthetic rope as well – they protect your hands from cuts, abrasion, and rope burns.

6. Winch Line Damper
Placed over the rope during operation, it reduces recoil if the line snaps, increasing overall safety.

7. Rope or Strap Extension
Provides extra reach when the nearest anchor point is farther than your rope’s standard length.

8. Recovery Gear Bag or Organizer
Keeps all your equipment in one place, protected from dirt, moisture, and damage.

With the right accessories, your winch becomes a versatile and safe recovery tool – ready for anything from a light assist to a heavy-duty off-road rescue.

It’s the maximum load that a piece of equipment (like a strap, shackle, rope, or chain) is rated to handle during normal use. This value is set by the manufacturer based on safety factors, meaning the actual breaking strength of the equipment is higher, but you should never exceed the WLL in real-world operation.

• Example: If a recovery strap has a WLL of 5 tons, it means you can safely use it for loads up to 5 tons under normal conditions.

• The WLL is usually calculated as Breaking Strength ÷ Safety Factor. For lifting gear, the safety factor might be 4:1 or higher; for recovery gear, it can vary.

Key point: WLL is about safe working capacity, not the maximum it can physically hold before failure.

A marking such as 3 / 21 T on a recovery strap usually means:

• 3 T – the WLL (Working Load Limit) or safe working load of the strap. This is the maximum load that can be safely applied during regular use.

• 21 T – the breaking strength (also called ultimate strength or minimum breaking strength), which is the load at which the strap will fail in a controlled test.

In this example, the strap is rated for safe use at 3 tons, but in a laboratory test, it can withstand up to 21 tons before breaking. The difference between the two numbers comes from the safety factor applied by the manufacturer – in this case, 7:1 (21 ÷ 3 = 7).

Key point:
You should always work within the lower number (WLL) to maintain safety and prolong the life of your recovery gear. The higher number is there to indicate its ultimate tested strength, not the load you should use in real-world recovery.

1. Why choose synthetic rope over steel cable?

• Improved safety – when it breaks, it doesn’t store as much kinetic energy as steel, reducing the risk of injury.

• Lightweight and easy to handle – often several times lighter than steel, with no sharp burrs to worry about; easier to spool in and out.

• Field repairability – damaged rope can be rejoined or spliced without specialized equipment.

• It floats – ideal for water crossings and wet environments.

Cons: more expensive, more vulnerable to UV exposure and dirt, and requires regular maintenance.

2. How to choose the right diameter and length?

• Safety margin – rope strength should be at least 1.5–2 times higher than your winch’s maximum rated pull.

• Balance between diameter and length – thicker rope is stronger but takes up more drum space; sometimes a shorter main rope with an extension is the best option.

• Avoid overfilling the drum – too much rope can damage winch components and reduce pulling efficiency.

3. What are the best materials for synthetic winch ropes?

• Commonly made from HMPE fibers (such as Dyneema), polyester, or nylon – all highly resistant to moisture, corrosion, and offering exceptional strength.

• Rope construction (e.g., 12-strand braid) affects durability, abrasion resistance, and how easily it picks up dirt.

Various winching situations

may require the use of different winching techniques.
This could include situations such as too short a distance to achieve maximum pull using a straight-line setup,
or the need to increase pulling power or maintain the rope in a straight-line pull.
You must assess which technique is appropriate for your situation.
Always remember to think safety first.

How to change pulling direction? This is also where a snatch block comes in

When winching, it’s best to keep the rope running in a straight line from the winch to the object being pulled. This ensures even spooling on the drum, improves efficiency, and reduces the risk of rope damage.

Using a snatch block attached to a point directly in front of the vehicle allows you to change the pulling direction while keeping a 90° angle between the rope and the drum. This ensures the rope spools properly during operation.

A snatch block can also increase pulling power

In some situations, you may find you need more pulling power.
Using a snatch block provides mechanical advantage, which directly translates into increased winching power.

Double line

Winch pulling power decreases as the number of rope layers on the drum increases.
Using a snatch block in a double-line setup allows you to pull out more rope from the drum, reducing the number of layers and increasing pulling power.

Step-by-step:

1. Spool out enough winch rope to free the hook.

2. Attach the hook to the vehicle’s frame or tow point, then pass the rope through the snatch block.

3. Disengage the winch clutch and, using the snatch block, pull out enough rope to reach the anchor point.

4. Do not attach the hook to the winch mounting bracket.

5. Secure the rope to the anchor point using a tree saver strap or a choker chain.

6. Attach a shackle to both ends of the strap or chain, making sure not to overtighten – tighten and then back off half a turn.

Triple line

Similar to the double-line setup – as shown in the diagram – except the rope end is routed through two snatch blocks, with the third point being, for example, a tree.

1. What is a roller fairlead for a winch?
   A roller fairlead consists of four steel or aluminum rollers that guide the rope during winching. It is mainly used with steel cables because it reduces friction and prevents excessive wear when winching at an angle.

2. What is a hawse fairlead?
   A hawse fairlead is a smooth plate, usually made of aluminum or steel, with a rounded opening through which the rope passes. It is designed specifically for synthetic ropes – minimizing wear and protecting them from abrasion.

3. Which option is better for synthetic rope?
   For synthetic rope, a hawse fairlead is strongly recommended because:

• It has a smooth surface that won’t damage the rope fibers.

• It has no moving parts that could pinch or fray the rope.

• It’s lighter and more compact than a roller fairlead.

4. Can you use roller fairleads with synthetic rope?
   Yes, but only if they are in perfect condition – with no sharp edges, rust, or pitting. Even minor damage to the roller surface can cut or weaken synthetic rope.

5. Can you use a hawse fairlead with steel cable?
   It’s not recommended. Steel cable combined with a hawse fairlead generates more friction, wears it out faster, and can cause serious damage when winching at an angle.
