Bats without composite materials in the barrel can have any drop. Bats with composite barrels are permitted in Junior League but must meet the BBCOR .50 standard and be permanently labeled so.
In the example, our order is for 150 cubic yards of concrete with each truck carrying 10 cubic yards and unloading every 10 minutes. We further estimate that the travel time to the job is 20 minutes and that your plant takes 5 minutes to load a truck. Divers will check the load after batching, which takes 5 minutes.
If a concrete truck can't access the drive due to weight, how could a conveyor truck? Most of the weight comes from the concrete, not the truck. I don't think they can stretch 150 feet either, or that they are necessarily so common as to be found in most towns/cities. However, I could be wrong.
