I thought others here might find this useful.

I wanted a way to easily get my truck cap on and off by myself, which also a way to store it without taking up more floor space. Here was my solution:

I already had the winch from a previous project. My cap has side windows that open upwards, and no screens, so putting some 2x4's through the window opening was the easiest way to lift it. This particular cap has fiberglass extending down beyond the rails which rest on the bed (which covers the cap, giving it a more finished look), so storing this on the floor, or on a pallet rack would require clamping some boards to the rails to keep from putting any load on this fiberglass. It is a simple design with four cables to four pulleys to the four corners of the cap. This cables gather together to one, the coupling of which go across the ceiling to another pulley, and down the wall to the winch. I made the coupling go across the ceiling, as there wasn't enough distance from the pulley above the winch to the winch to be able to give it enough range to lower the cap to the floor if needed.

Once the cap is raised to storage height, I connect four safety straps to it to prevent accidentally lowering, or falling due to a winch failure, or curiosity of my 5 year old daughter.

The cap is actually over the cab of the truck where I normally park, as I had to have it far enough from the overhead door to keep it out of the way when the door is up. I just have to move whatever is parked in front of the truck so I can pull in a little further to get the cap on or off. I suppose I could back in to mount/unmount as well.

Genius ... :thumbsup: :thumbsup:

I dont have a cap for this reason. I would have to have help come over when I wanted to remove or put it back on. I have thought of something like this, but ultimately I would have lowered the cap to a dolly that I could roll around.

I would be interested in see a few more photo of how you tied the 4 cables together.
This is another reason to build with at least 12' ceilings.

I used the following type cable clamp for the cable connections:

I connected the four cables to one side of a swivel (see picture as follows), and the main cable from the winch to the other side.

I've been thinking about setting one of these up. Thanks for posting, the ideas are appreciated.

I tried something simular and it kinda worked, I did not take the idea far enough. I used ropes and "eye" hooks, it was a pain to keep the cap level. it allways seemed to want to tilt one way or the other.Do the rollers keep the resistance even on all 4 corners?

You might could do the same thing with a pair of bike hoists. You'd want to check the load capacity versus the weight of the cap to be sure it didn't break and drop on your truck.

Yes, the rollers keep the cable moving nicely, even when lowering the cables without a load.

Most fiberglass caps are probably way too heavy for a bike hoist. I like overkill. The four smaller cables are rated for 800 lbs each, and the larger cable 2500 lbs. My cap probably weights 200 lbs.

Might work on a subcompact aluminum topper.

Quite a rig you built. :thumbsup:
