This is the crane he made. It has an extendable arm that slides out when needed. Works great for putting trusses on roofs since you can't always get a boom truck when you need one. Often the ground isn't suitable for a boom truck whereas a skid steer can go anywhere.
He also made a "man lift" platform for working on high objects. Works great when securing sleds in trees! That's me mounting a bird house 25 feet up on a tree.
This is the observation tower we put up this summer overlooking the dragstrip.
No lack of creativity here!!!
