    Any ideas?

    Re: receiver, you can weld day 5mm flat bar either side of the receivers

    Re: rack, weld some crush tube in with the ID the same size as the pin

    This will beef it up while keeping the weight down.....

    Where bouts are you mounting to the trayon??

    The rack is great, but in reality only needed when we're using the Trayon, hence my thought of attaching a custom rack to the 'sleds' of the Trayon. When the Trayon is off, we can carry the bikes in the tray of the Defender.

    I thought about crush tubes in the inside of the vertical sections of the rack, but your good idea about the plate on the outside of the receiver will help. Now you just need to think of a way to lift it

    Have you had a look at this type of unit, thousands to choose from on flea bay.
    1500N equals 150Kg

    Stroke Length 6'' 12'' 14'' 18'' DC 12 24V Linear Actuator 1500N Electric Motors | eBay

    Check the speed on the various units as some can be quite slow.

    Cheers Glen

    Use two bits of round bar at the top and bottom which will help keep it spaced, paint them with a Teflon. Based paint then run a nylon rope like a primitive block and tackle.

    Simple and easily field repairable and adjustable.due to load or the person making the effort.

    Perhaps you could use a mechanism inspired by something like this

    That's what I originally imagined, but I think Blknight is on to something with his simple pulley/rope suggestion.
