There are mainly two kinds of airport passenger stairs, one is towable passenger stair, another is self-propelled passenger stair.
The self-propelled passenger stair is made of ISUZU vehicle chassis, under-frame, going aboard ladder, going aboard platform, fine tuning mechanism, hydraulic system and electric system etc.
The height of its platform could reach 5800mm after slight adjustment, so this type of passengers stair could be applied for A310, A320, A330, A340, B737, B747, B757, B767, B777.
The towable passenger stairis a new type of non-motorized passenger ladder developed by our company. It is beautiful in appearance, sturdy in structure and light in weight. The passenger platform is 2600~3200mm above the ground. The boarding ladder is suitable for B737-200, B737-300, B737-500, B737-800, A320, A321, DC-8, TU-154 aircraft .
As towable passenger boarding ladder has no car disk and engine, it greatly reduces the user's operating cost and is economical and durable.
