This page reproduces a G4049 engine vertical installer data sheet. For additional information, photos, and diagrams, see my F-1 rocket engine G4049 engine vertical installer page.

The engine vertical installer is an electrohydraulic-operated, self-propelled, lifting and positioning unit for the engine. (See the figure for leading particulars.) The vertical installer consists of a dual-pressure hydraulic system, electrical system, control console, manually-operated tilting mechanism, manually-operated horizontal positioning mechanism, a hydraulically-operated azimuth drive, a pair of hydraulically-operated drive wheels and gearboxes, and a three-stage lifting cylinder, all supported on a triangular frame. Twelve wheels, including the hydraulic drive wheels, support the vehicle frame. It also has an attachable tow bar. The vertical installer platform or cylinder can be operated manually with control valves on the control panel, or remotely using the remote-control station. The drive wheels can be operated from the control panel only.
