Abstract: A disclosed pig trap door device serves as a tool for opening and/or closing a pig trap door of a pipeline. The pig trap door device may be fixed to a hinge portion of the pig trap door at a hinge attachment and may also be movably coupled to the pig trap door with a force actuator at a door attachment. Operation of the force actuator causes the door attachment to rotate the pig trap door with sufficient torque to seal and/or remove the pig trap door.

Abstract: A disclosed lift device serves as a work piece handling tool for performing service operations on a mechanical component, such as a power cylinder head of a gas engine compressor. The lift device may be attached to the cylinder head and used to securely and efficiently remove (and install) the cylinder head from the gas engine compressor. The lift device may also provide a free-standing base for holding the cylinder head securely in a manner that provides access for servicing operations. The advantages of the lift device include a single mounting and unmounting operation for the entire duration of the servicing operations.
