  • Patent number: 8769787
    Abstract: A head lifting device for lifting the head off of an internal combustion engine. The head lifting device is typically used for an engine having multiple separate heads. It includes a crane assembly that has a support member. At one end of the support member is a bracket for attaching to a first head. At the second end of the support member is a gearbox. The second end of the support member is positionable over a second head, the second head typically being adjacent the first head. Hanging down from the gearbox is a shaft threaded, and at the end of the shaft is an assembly for engaging the second head. Driving the gearbox will allow the shaft to move upward through the gearbox and, with a second head attached thereto, allow the second head to lift off the engine block.
