HOW TO: DOUBLE LINE PULL WINCHING
MAKE YOUR WINCH TWICE AS POWERFUL, WITH FIVE MINUTES’ WORK.
LEVERAGE IS the cornerstone of everything we do off-road. We fit larger tyres to provide a mechanical advantage in the rocks and ruts. Dropping tyre pressures also gives us a mechanical advantage in soft sand and mud, by spreading the same weight over a larger area. Even selecting low-range is making use of mechanical advantage, as we’re halving the speed but giving the motor double the time to do the same job. Think of it like taking two swings of the hammer to drive in a tent peg, rather than one. That’s the basics of mechanical advantage, and it’s why we’re always in pursuit of lower gearing, bigger tyres and slower winches.
It should be clear by now how important mechanical advantage is in a 4x4, but what mightn’t yet be obvious is where I’m going with this – bear with me for a minute. Your average off-the-shelf electric winch is going to punch in at 12,000lb pulling force – for those readers in the 21st century, that’s 5443kg. Considering both the Y62 and LC200 can legally weigh in at more than 6000kg loaded up with a trailer in tow, it becomes obvious a 12,000lb winch mightn’t always get you out of trouble, especially when you’re stuck to your axles in sand or mud.
The trick is to give your winch more pulling power. Now sure, there are fancy high-mount, competition-spec winches, or elaborate hydraulic winches, but in the majority of cases your 12,000lb winch is more than capable of doing the job with a double line pull. By using the mechanical advantage of a double line pull, we’re able to slow the winch-line speed down to half, effectively giving the winch motor two swings of the hammer where it used to only have one.
