The Boeing 737, a narrow-body aircraft produced by Boeing Commercial Airplanes since 1966, was developed to address the need for a short-haul aircraft complementing the larger 727 airliner, particularly for short and thin routes. Boeing drew inspiration from a pre-existing concept, which served as the foundation for the new aircraft design. A significant development from the initial design involved relocating the engines to the wings, departing from their previous placement at the rear fuselage. This adjustment brought several advantages, including a lighter wing structure, increased cabin space for passenger seating, as well as improved aerodynamics.
In 1985, Boeing sought to bridge the gap between their 737-300 and 757-200 models by introducing the 737-400. The new model was extended to accommodate 188 passenger seats, necessitating the fitting of the aircraft with a tail bumper and strengthened wings.
Red Box is delighted to present an extensive range of ground power equipment for this aircraft, including tugs, ground power units, start power units and more, all meticulously tailored to meet the specific requirements of the Boeing 737-400 aircraft.
