DRIVING/TOWING - RECOVERY TECHNIQUES

BUSH WINCH ON TEST
A wheel mounted alternative to the electric winch.

This hub-winch design uses two drums – one for each opposite-side wheel and can be used going forward or rearwards. Each drum attaches to a wheel hub, using specially-shaped wheel nuts.

Bush Winch is a Western Australian based company, headed by geologist Patrick Verbeek. Over the past 10 years he’s been  developing and producing a hub winch for popular 4WDs.

The original design fitted popular six-stud Japanese-design wheel ends, but a 2019 two-piece Series II design fits a much wider range of 4WDs.

This hub-winch design uses two drums – one for each opposite-side wheel and can be used going forward or rearwards. Each drum attaches to a wheel hub, using specially-shaped wheel nuts.

The new generation,Series II Bush Winch is a moulded product, with a very high 60-percent long glass fibre content, bonded with an industrial grade nylon polymer. This material is used in many defence, automotive and aeronautical applications.

It is manufactured in Australia for Bush Winches and Anchors Pty Ltd (BWA) by Axiom Precision Manufacturing under ISO 9001 (Quality), ISO 14001 (Environmental) and AS9100 (Aerospace) accreditation.

The Series II was developed to expand the fitment to a much larger range of vehicles and to incorporate slight improvements to the original design.

Without any weight gain from the previous aluminium model the Series II is considerably stronger and can now accept loads in excess of four tonnes.

 

How it works

Bush Winch differs from other winches in using two ropes – one on each drum – so two wheels are doing the winching action. The drums can be used without other gear, on front or rear wheels, or in conjunction with rope-guide hub attachments that allow steering while winching.

Part of the kit is a set of replacement wheel nuts. They differ from the standard nuts in having a ‘waisted’ top, like a wine glass. The hub-mounting section of the Bush Winch locates and clicks into place on these nut extensions.

The guides have swivel-eye ends that ensure the forward-running ropes don’t foul the front wheels or vehicle parts.

If the desired recovery direction is rearwards the ropes run straight behind the vehicle, without the need for rope guides.

Hub-mounted winches aren’t new, having been around since before World War II. They were popular on military vehicles and trucks that ventured off-road.

One problem was the buildup of rope on the drum surface as the vehicle winched itself along, because layers of rope thick enough to handle the weight and torque soon exceeded the drum’s storage well.

That issue has been resolved by the development of modern synthetic rope. It’s possible to have five-millimetre-section rope with a breaking strain of three tonnes, so two strands of that are more than capable of pulling a 4WD out of a bogging – even uphill.

In addition to using synthetic rope Patrick Verbeek’s Bush Winch kit can include what he calls ‘soft’ shackles: shackles made of the same synthetic rope and that lock into place using a button-nut and a sliding loop.

Soft shackles are gaining increasing popularity with 4WD owners and have already established themselves in the racing yacht fraternity.

The advantages over a traditional metal shackle are less weight and much lower mass, should the shackle give way and become a missile. Also, with the Bush Winch’s twin-rope tackle, the ropes can be joined by a soft shackle that will pass over an anchor-point pulley, to equalise axle differential action and ensure that both ropes share the winching load equally.

We were somewhat skeptical about the Bush Winch’s ability, given the skinny ropes used, but our bush testing soon dispelled any fears. Winching forwards or rearwards was fuss-free.

Pricing for the second-generation Bush Winch  basic kit – drums, wheel nuts and synthetic rope – is in the $500-$650 bracket.

 

Bush Winch ground anchors

In most boggings there’s something to winch off, but on sandy beaches there’s often nothing. That’s when a ground anchor is necessary.

We’ve tested various designs of ground anchors over the years, with a remarkable lack of success. Indeed, the first-generation Bush Winch ground anchors were OK in firm sand, but didn’t get a grip in the deep soft stuff.

The Series II ground anchors have longer, heavier augurs and come with hinged ‘shovels’ that give wide lateral resistance in deep sand. We used two of them in the second video below and they hardly moved as our three-tonne LandCruiser winched itself out.

We also managed to haul ourselves out using only one anchor and you can see that it moved very little in the process, with no tendency to pull out vertically.

The downside is bulk and weight, with the twin-anchor pack weighing nearly 19kg.
