Moving bees by the hive can be a backbreaking experience, especially if you are doing it by yourself. I know. I have been there, done that, and got the scars to prove it. I finally broke down and bought a hive lifter (sometimes called Hive Carrier, or Two Man Hive Lifter/carrier). The only problem with it is, I have to find someone willing to go with me to the apiary and brave all the stings because the bees do not really want to be moved.
I do, however, have a friend or two willing to do just that. I even get a new beekeeper to help on occasion just so he or she can get the experience of moving bees and also be able to borrow my lifter for their own hives. Small price to pay for the help I receive.
As you can see in the photo taken from the Bushy Mountain Bee Farm catalog, it takes both of you to move the hive. Just place the tabs in the hand holds, front and back (the lifter is too narrow to go cross ways), and lift. This distributes the weight equally between both workers so you can actually pick up twice as much poundage as you could by yourself. You can even use the lifter to carry only honey supers. It is great when robbing, and really does speed up the process.
