OK here's how it looks under construction.
I added parts with clamps and magnets to help you vizualize better the tie down posts that will hold the bike on when finished. The post up front will be so I can reach the tie down straps by reaching over the fuel tank.
The winch is attached to the front side of the wheel stop of the rail. This will have a wireless remote control to run the cale in and out. The remote, like a key fob, I will be able to work with my left hand while holding onto the handlebars when loading. Since the winch will be doing all the lifting I won't have to worry about braking, but I can work the hand brake if I need to.
Here you can see the rail in the down position with the tip on the ground.
It lowers as it swing out!
This is how the winch will raise the rail back to the horizontal travel postion. The clamps are for clarity. There will be a chain link ring attached to the side of the rail near the back wheel. The cable will run through a snatch block pulley and when ready to raise, I will attach the end of the cable hook to the base on the right side to pull the rail up into position. There will be another rear tie down post on the left side of the right side rail clamp on the right platform to hold the rail down and in position. The snatch block pulley will float when pulling the bike up the rail. The winch will hold the bike against the wheel stop until I strap the bike down to the rail. Then I'll let out the cable and use it to pull the rail with the bike strapped to it up to the travel position.
Just in case some of you guys with tall hard sided campers are thinking about how you could use this idea on your tall truck. You can add a temporary rail to the rail tip to lengenthen it if your truck frame is higher off the ground. Just add narrow fold down or removable platform to the bike rail so you can walk up with the bike. Heck, just put the platform on the inside and you won't even have to remove it! Simple!
And if my carrier ends up hitting the ground too much I'll raise it and add an extension.
Let me know if any of this doesn't make sense. I've had years to think about this, so I'm sure I've forgotten something. This is actually my second one. I built one about 30 years ago to go on the back of my Pop Up Trailer to carry a CT 110. Always worked great!
WOW! I'm sorry, I thought I could explain this real easy and it got complicated the harder I tried to explain it.
