When you set your camera up on a Crane and start adding weights, it's a real pain to move that thing around. Unless it's on wheels. The same goes for heavy lighting equipment.
There's a couple of top heavy light stands in the studio loaded up with a set of lights, and to prevent them from falling over i've got a couple of sandbags over the bottom. Once the sandbags are in place, it becomes annoying having to move them around, so I opted to upgrade the stands with these Wheeled Caster Adapters. These little casters simply fit on the ends on any light stand and tighten in place.
These casters aren't cheap at about $12/each wheel, but they sure do make moving heavy stands around much easier regardless of how many sandbags you're using. It's also much safer moving this type of equipment around (for the crew and for the gear). If you're in the same pickle, I highly recommend looking into these things.
I opted for an inexpensive set since I don't move the stands very often, but there are dozens of different options via Amazon (found here).
