aircraft passenger step

JSTY5080KTE aircraft passenger step is mainly composed of electrically driven chassis, fixed and sliding ladders, hydraulic system, electrical system, etc。 4.1 Chassis Chassis body by special steel welded together, center of gravity, good stability. The chassis is covered with a cover plate, which can be removed to facilitate maintenance of the parts. The chassis is equipped with four hydraulic stabilizers to ensure the stability of the passenger step when boarding. The chassis consists of transmission, steering, braking and cab. The drive system USES the motor controller to control the variable frequency speed-regulating traction motor as the prime power, and transfers power through the reduction box, drive shaft, main reduction drive axle, rim and tire. Motor controller and traction motor using the industry's most influential top products; The gearbox is manufactured by Siemens. Suspension for front and rear longitudinal plate spring, and equipped with hydraulic cylinder type shock absorber. The steering system controls the front wheel steering by driving the steering cylinder with the electric hydraulic pump through the full hydraulic steering device (Eaton or other famous brand products). Brake system is electric vacuum pump to provide vacuum assisted braking, front and rear drum type, double pipeline hydraulic braking system. The large area arc windshield is adopted in the cab, which can broaden the vision and facilitate the observation of docking with the aircraft.
