A Step Ladder and Hand Truck are two pieces of gear that we commonly have handy when carting around to a location. Well, here's a handy quick tip from HDSLRNOW.com regarding a combo step ladder / hand truck unit. The one featured in the video is the more affordable $65 dollar version, but there are other more expensive LadderKarts following the link via Amazon (click here).

I've had one of these for a few years now and it's fantastic! I've even been able to move a refrigerator and range around with it. Like josh mentioned, it's no good for stairs.
i have one of these, just want to point out that while i use it all day, and on every shoot i do (events and bar mitzvahs etc) the cart is no good for stairs, the wheels are not big enough to roll up without scraping. so find the elevator!
I have a large Kart A Bag hand truck, and a stepladder/hand truck would be a great addition for my work!
I bought one of these 6 months ago for the same use, works extremely well for elevated shots. As the reviewer points out, the cart also comes in very handy. Vin
