A removable, truck mounted crane with both an inclined boom for high lift and a horizontal telescoping boom for extended reach beyond the truck. The crane has two winches either of which can be routed to either boom. The high boom can be used normally for hoisting or to support the horizontal boom when extended. In addition, one winch can be used to retract the horizontal boom while under load. A rolling storage stand with winches is used to support the truck tailgate while enabling one person to install or remove the crane from the truck.
