We have been trailering beehives since 1979. Our standard model is made of
an "I" beam chassis and 3/4 inch angular bars. It holds 10 colonies. We "M"
lock the hives on for travelling. For short distances, we use masking tape
on the entrances - we use ventilated lids. We use travelling screens for
long distances. Axles are center mounted, so one person can maneuver and
position a trailerload. We have had great success with them. Moving is a
breeze. Now that we have hundreds of colonies, the problem is mass producing
the trailers.
