I'd much rather have a crane than a boom truck. Their outriggers never seem to go out far enough or be large enough. I'd take a 18 ton crane over a 25 ton boom truck anyday. I rent cranes with operators that have a lot of tree experience. I don't like to "cold call" crane companies. I usually ask other people which company and operators they use. A poor operator can make for a very stressful and long day. A large crane with a skilled operator can make the the most difficult take down an enjoyable day.
Its weird they put down plywood because the ground was to soft for the 10 tire on the crane but no support on the 4 outriggers that hold more weight than that.
