NOTE--I updated the picture links a few post down so they should now be viewable. Thanks for looking!!
When I was bricking my garage, I needed a way to lift loads of bricks up to the scaffolding. My skid steer would not lift high enough and I didn't want to rent a telehandler for a long period of time.
The made my own small pallet lifter -- similar to what you see on the knuckle boom trucks for picking full skids of material. Since I was only using a small Harbor Freight hoist, I sized the pallet lifter to be of a reasonable size.
I also had to make a special trolley to attach the harbor Freight hoist the to I-beam.
I used a couple of 3" angle irons to sandwich onto the walk-thru scaffolding. Then the beam attaches with beam clamps. This allows the hoist to easily slide from one side to the center and to the other side if necessary.
