PT90-F Series, Engine Positioning Trailer

The photos above depict the PT90-F engine positioning trailer providing for the maintenance, removal and replacement of the four Pratt and Whitney engines on the C-17 Globemaster III aircraft. It incorporates work platforms, ladders, auxiliary platforms, winches and controls required to remove and replace the aircraft engines. It also contains electro-hydraulic systems to allow the trailer to move through 5-axis of travel to facilitate engine mating. It contains I-beam rails which mate with various support equipment to facilitate the removal, installation and roll transfer of a cradle mounted engine.

D&D has manufactured these units under US Air Force contracts as well as the Boeing C-17 Support Program and Foreign Military Sales.

Ground Handling Tire and Wheel Dolly

The Transport Tire Trailer provides a quick response capability for tire change outs on the C-17 Globemaster aircraft. D&D designed, developed and tested the trailer at the US Army Aberdeen Proving Ground putting it through reliability testing over a variety of terrain under differing weather conditions. The Trailer is designed with a hand operated four wheel lifting hoist to raise the landing gear to remove the tires. It will hold 8 inflated or deflated aircraft tires.

C-17 Engine Cradle

The engine cradle is designed to secure a Pratt and Whitney PW2040 turbofan engine (military designation F117-PW-100) to various ground support trailers for installation, removal and transport.

It is designed to fit on I-beam rails used on engine transport and engine positioning trailers.
