This is BSF series escalator. Its supporting structure of Graces adopts high strength, low rectangle steel. It is more firm and durable than common one. The carrying capacity and safety of Graces is greatly improved by this kind of supporting structure. The auto-lubricating system of Graces can add lubrication to driving chains in according to friction force. It drastically decreases the abrasion and energy consumption between the parts of escalator FOB QingDao Payterm: T/T Rise: 1500 mm ≤ H≤ 10000mm (30 degree) 1500 mm ≤ H≤ 6000mm (35 degree) Capacity: 9000 pessengers / hour Speed: 0.5m/s Step Width: 600/ 800/ 1000 (mm) Packing: Regular Delivery: 45days after the S/C confirmed Note: We can design and satisfy different client's special and individualized requirements.
