You can put a rig like this on any vehicle that you don't mind scratching.
My old Ford Pinto was great for moving old cinema equipment with such a rig.
I made an A-frame from two beams and lashed them to the rear bumper. The lift cables ran to the car's front bumper.
Question: Why not just use a forklift?
I used forklifts to collect a couple of these big steel frames for a greenhouse project.
It was a pain in the neck because they were too big to balance on the forks.
The next time a frame got thrown out I happened to have my tree moving A-frame on the truck.
Night and day! So easy and graceful I couldn't believe it.
This A-frame rig is based on boom trucks I saw in the oilfields of Centralia Illinois, my Mom's hometown.
The A-frame boom rig shown here consists of two poles attached to each other at the top forming a triangle.
Hinges at the bottom of the poles are bolted through my truck's bed.
Two winches are attached to the A-frame. One winch raises and lowers the A-frame. The other winch raises the load suspended from the A-frame.
This is big heavily loaded stuff. It's dangerous. Be very careful.
There are lots of ways for this stuff to break, fall, and crush you.
Don't use nylon rope or any material that can stretch.
That could make your rig into spring-loaded giant mousetrap.
Or a deadly whip-gun.
There are lots of warnings in this project. Your rig will be different and there will be lots of ways for things to go wrong that I won't know about. I'm always afraid when moving big stuff.
Step 1: The Other Way: Forklifts
The A-frame boom is better, quicker, easier, and safer than the clumsy stuff I was doing with the forks.
Question: Why are these giant steel frames being given away?
The people giving them away get paid too much to justify taking them to the scrapyard themselves, and the items are too big for the local scavengers to collect.
Step 2: Front Anchor Points
I poked holes in the top of my front fenders to run chain down to the frame and bolt it there.
The sheet metal of this truck is amazingly thin and flimsy.
Unlike all the mechanical stuff which is brutally strong.
On other vehicles I've anchored to the following:
tow hooks under the bumper
On a '68 Buick Electra that stuff is solid enough. Don't bet your life on your new car's bumper.
Don't bet your buddy's life on anything. Show her the whole rig and wait for consensus before
proceeding. Yell and make everything stop and step back if you hear any strange sounds.
Step 3: A-Frame and Winches
Laminate a pair of 2x4s together if you can't find any you trust by themselves.
A come-along is a winch with a ratcheting handle that you work back-and-forth instead of cranking it in a circle. Watch out for crank winches, if you free the ratchet dog the handle can spin and hit you really hard. It's a little harder to do that with a come-along.
If you don't have come-alongs use pulleys, deadeyes, or even a trucker's hitch.
Step 4: Position for Loading Up
Back up to the thing you want to load. I want to snug this up to my tailgate, so I position my truck just a hair in front of it.
Lower the boom until it's over the center of mass of the item you want to lift. That way it won't swing or drag. Be careful walking under the boom. If it falls all your projects are over.
Lower the lift cable and attach it to your load.
Step 5: Rig and Lift
Every rig is different.
I winched it up and it worked as planned. The front got lifted also and rested against the rear of my truck.
Backing out was a pain in the neck. I hadn't lined up perfectly and the load was too close to the fence.
Step 6: Stop and Check the Load
It was riding up in the front so I lashed it down to my trailer hitch.
One of my tires was low but I wasn't going very far.
The front wheels are lightly loaded. I step on the rear of the frame but they don't come off the ground.
The boom trucks in the oilfields had welded junk boxes on the front bumper. They'd throw scrap metal in there whenever they did a heavy lift.
When moving cinema equipment with my Pinto back in the day, the load lifted the car's front wheels off the ground, so my uncle rode on the hood. You can't do that any more. It's called "car surfing" and there are laws against it in many places.
A police car cruised by and admired my work while I was taking pictures.
Sometimes when I'm scavenging they think I'm dumping stuff and I have to explain that I'm doing the opposite.
Local towns have huge expenses from cleaning up illegal trash and junk dumping.
