winches and bak rak

[Rowan the Bruce]

Hi all, wondered if anyone has used a TDS gold fish 9.5 with dyneema for lowering awkward stuff and large lumps? also if any one has used a bak rak towball mounting plate?Superwinch Parts, Electric Winches and Winch Bumpers, UK – Goodwinch.com

 

havent used a winch for years other than a trusty tirfor and cant afford a GRCS or hobbs right now.

 

hope you can help

its it rated for hoisting duties, a Tirfor on the other hand have a SWL/WLL and can be used as hoist for lifting.

 

The amount of winches that can be used as hoist and can get a SWL/WLL is quite small and are normally worm drives like the FW525 and the Superwinch H14 etc as you would find on ex-utilities land rovers

wouldn't use dyneema for tree work,, it'll get destroyed..

One thing to watch for with any epicyclic geared winch used with a synthetic rope is the location of the drum brake; many winch designs (eg Warn 9000 series) have the brake inside the drum. A characteristic of this kind of winch drive is that the brake will get hot - very hot indeed - during prolonged paying out under load (ie lowering) operations. This can easily cause the drum to get hot enough to melt a synthetic rope.

 

However not all epicyclic winches are like this, and looking at the exploded photo of the Goldfish 9.5 on DB's website it looks as though the brake is outside the drum so it likely to be less of a problem, although it may still be a problem.

 

Personally I don't like any epicyclic geared winches (give me a Superwinch Husky any day) but they are so much cheaper they are popular. I would never use one for prolonged lowering or paying out under load, since even if you don't destroy the rope you'll wear out the brake quite quickly.

 

For this application (lowering) I would be more inclined to go for a traditional mechanical capstan winch (which used properly can do almost anything), or failing that a mechanical or hydraulic drum with a steel cable.

i assume if your looking seriously at using the bak rak system, that you will be using a redirect at the base of the tree as there is no way i would want to shock load this system in a vertical direction as its only a small pin that holds it on the tow hitch, and is designed for horizontal pulling really, also given the length of most winch cables is this not going to end up putting your 4x4 in the dropzone so if something went wrong your going to risk having your vehicle damaged, unless you use a smaller diameter longer winch cable i dont see that this is a realistic solution, i think a capstan winch would suit your needs better and be more versitile for you, but it depends on if your using a vehicle you can install one on (defender only) or look for a petrol capstan setup.
