Swing out spare wheel carrier

May I suggest that before you invest your time designing safety devices that you actually get some struts and look at their travel damping?

The ones I have in front of me from a Honda civic take all my body weight to compress (one) yet when released take ~3 seconds to reach full extent. Admittedly travel is at its fastest when initially released, but still remarkably controlled & IMHO the only danger would be if incorporated into a scissor lift or another similar mech it'd make a rather effective guillotine.

If safety conscious, why not just use a hand winch / leadscrew to hoist a parallel motion carrier?
 
Google for hmmwv spare tire carrier. It has a ratchet mechanism to lower the spare. I'm sure you could change the mechanism to air or hydraulic.
 
A Defender or Discovery spare is too heavy for a lot of guys, never mind girls!

My D2 alloys with 255/65R16 tyres are as much as I want to have to chuck around.

The old EKA Scammells and Fodens had a winch and swing-out carrier, but their wheels were something else, 18" or 20" wise sand tyres on many.

Hi, Tim,
Found this thread as I'm looking for a similar resolution having had two heart attacks that mean humping the wheel off and on the rear door carrier is a no no.
What was your conclusion on this?
My idea, I've ordered the winch to play with, is using one of the small electric wireless controlled winches set in the rear roof header above the door.
They're about 4ins square mounting plate which looks just about right space above rear door of Defender 90. Mounted there I can use it to lift off/on the wheel but also with door open can lift heavy tool kits etc up to floor height and just push into rear. Rear header will need an internal reinforcement on the Ali panel plus water ingress protection around cable but all doable.
That's my summer project this year anyway.

Hi Morgan
I do not have a completed carrier as yet but am constructing one, I looked at the link in the last post and also at the one attached and my carrier will be a an amalgamation of both.
It will be manually wind down and up with a spring assist so that even the winding will be easy.
I like your ideas for the roof mounted winch this could be mechanical or electric but like you say it will have to be reinforced.
