I've been trying to find a piece of equipment to help me move my hives singlehandedly. Every once in a while, I'll see a picture of a odd looking dolly/hand truck, that can be used to move hives with only one person. (I'm a one man band.) It seems to have an extra arm that clamps on the hive to hold it in place and keeps it parallel to ground.
Does anyone know where I could buy one?
