I have a job starting later this week placing 2 tractor trailer loads of boulders. After the rocks are off loaded I like to hang them from a chain so we can rotate them in the air while placing them. If anyone uses a method like this do you have a simple rig set up for this? We just use a chain wrapped around the rock right now but need a faster way to rig 90 to 100 rocks. If possible remember a picture is worth a thousand words.
