Except that a highlift is much more unstable - and that's what makes it dangerous.
Mega useful though. |

^^^ +1 High-lift is an extremely dangerous device if not used correctly. Much more difficult to use safely than a normal jack. 2002 110 TD5 White

You are absolutely correct in what you say, it's the operator that makes it dangerous. No more proselytizing from me  2002 110 TD5 White

I agree - but semantics or a little pedantic to say the tool isn't dangerous I think - the salient point is clear that some tools have a greater risk associated with using them. |

Yes, my post came out a little more pompous than I intended, but I have never understood this danger fixation people have with high lift jacks. Every time a high-lift gets mentioned in a thread, there is an explosion of doom and preaching!
Yes, you can hurt yourself and do silly things with one, but winches have more potential for widespread carnage than high-lifts, but there isn't the same doom-mongering when a winch is netioned. Operating a Defender off-road is far more dangerous and likely to result in pain and suffering than using a high-lift, but there isn't the same immediate outcry. Of the tools that anyone can walk into a store and buy, chainsaws are probably the most deadly if not used correctly, but even with chainsaws there isn't the same hysteria! What is it about high-lifts? This modern culture where people have to be protected at all costs from their owwn stupidity and limitations is totally anathema to me. Its ultimate conclusion is that anything with any element of hazard is outlawed. The human psyche needs danger - it thrives on it - it has driven mankind's greatest achievements - so let's keep a sense of proportion. Besides if the terminally stupid are prevented from doing entertaining and fatal things the world will soon be overrun with them! Sorry, rant over, I'll go back to sleep now! |

Nothing dangerous about the Hi-lift if correct precautions taken and the Operator has a full understanding of how it works and how to use it. It's the ignorance of the Operator that causes the accident and that goes with just about anything.
Just remember to put Difflock on before jacking the Defender. Oh, and handbrake of course!! The mud and dirt will not be good for the Hi-lift on the back, but even worse are the little stones that could be hitting it at up to 100mph after being thrown up from the tyres |

Never seen one but this could be a good way of protection if leaving on the outside:

Thank you all for the replies, I have noted and understood them but a hi-lift is what I have. How can I mount it safe and securley to the internal bulkhead? 2001 90 TD5 CSW Alveston Red Manual

Any one of the commercially available kits will see it done right, just depends on what you like best and suits your pocket:

it's too easy for one to come unclipped or fail over time, especially if other people use the fastening and shall we say are "mechanically unsympathetic"  |

I had it mounted on the bulkhead in my previous 90 ... With a pair of 4xRAC mounting brackets.
I haven't any pictures on my phone to share - thought I will at home ..... But it went there really neatly with the tub supporting the heavy end rather neatly. I still have the brackets but haven't arrived at a mounting solution in my new 90, which has a bulkhead removal bar. |

I have seats in the back so making it difficult to use the brackets. Instead I have it right up against the bulkhead just in front of my rear seats and then use a ratchet strap to attach each end to then seat frames. 2015 RRS Autobiography SDV6
