An interesting problem has just developed across the road from me. A 60 ton, 10 wheel crane backed down the hill to erect precast concrete walls for a new house. Now its stuck. Its built itself into a tight space and now it can't straighten up sufficently to get a decent run back up the hill. The ground is soft from recent rain. If the ground was dry and firm it would be able to inch its way around until its facing in the right direction, but at the moment its actually sideways to the slope that its trying to climb, and its just digging itself in. I feel sympathy for them, but this should make for an entertaining weekend.
Pre-cast concrete walls on factories are common enough but apparently this is the first domestic house to be built like this in this state. The walls are a sandwich construction with about 3 inches of concrete each side of a foam core.
