Abstract: This mobile, cylinder transport cart is based on a four cylinder transport cart, designed to minimize the handling of nitrogen and oxygen cylinders in the loading, transporting and servicing process and to provide boosted compressed gas for an aircraft, oxygen to fill crew and passenger oxygen bottles. The cylinders are locked into place by a cylinder locking clamp. The rotational loader is locked into place by a spring loaded plunger that locks loader into in either horizontal or vertical position.

Abstract: This Mobile Driven Hydraulic Power Unit (HPU) provides a source of clean, pressurized hydraulic fluid for performing required aircraft maintenance. The unit sits on a heavy duty towable frame designed for off-road terrain. Electric start engine, fully instrumented operation panel for both the engine and hydraulic system. A gasoline engine or diesel engine may be used to power the HPU.

Abstract: This two-stage jack apparatus for lifting aircraft comprises: a tripod base having three legs; a base tube; a ring having an orifice therethrough, wherein the ring engaging end of each leg is attached to the ring; a cylinder housing a jack wherein the base tube supports the cylinder and wherein the cylinder extends through the orifice of the ring; a two stage hydraulic extension attached to the jack; and a dual speed hand pump comprising a high volume low pressure pump for quick ram actuation to the jack point and a low volume high pressure pump used to actuate rams with a hydraulic pump.
