Over the last couple years, when serving in third-man roles on larger sets, I've discovered some elegant and cost-effective solutions to getting heavy stuff around the set. These are pretty cool carts when you are still saving your pennies for a Backstage Taco Cart:
BTW, some of these were on a 10-ton G/E truck for a $6M feature.
Set Cart #1 - The Stinger Bucket
A Rubbermaid trashcan strapped to a regular hand truck serves as a stinger bucket. The trashcan can be released to use the hand truck for other cartage. Securing a small box above the bucket can provide a spot for three-fers and adapters. Can also be used to carry cribbing. Sand bags might be a bit too much for this rig. Materials: trash can, common hand truck, buckle strap - $100
Set Cart #2 - Apple Box Coffin
1/2" plywood constructed into five sides of a box can carry four families of apples on a hand truck. Materials: sheet 1/2" plywood, screws/glue/etc., metal strapping, fender washers, 2x eye bolts, bungee, hand truck - $120 I helped finish this one, getting the straps all secure and grinding off the screws protruding into the box.

Set Cart #3 - C-stand Cart
Rather than buying a c-stand cart, I built my own by welding elements that bolt to yet another hand truck. I subsidized the cost of my small welding rig with the savings of building over buying. Welding with today's wire-feed rigs available at Home Depot is surprisingly easy. Mine is the 110volt Lincoln-Electric 3200HD.
