If you are looking for a truck that does a lot, the Crane Truck is it! There is a cab with a driver and the crane is permanently attached to the rear truck bed. Made of walnut and maple, the unit measures 15 inches in length, 6 inches wide and 11inches high.. The crane is fully operational - a hidden small peg fits in a hole to lock the crane in place once the desired height is reached. To release, just pull the knob out of the hole. The string has a hook attached to the end and can be looped around any load for moving.
