2640 ~ 3600mm hand-pushed passenger stairs body assembly

2640 ~ 3600mm hand-pushed passenger stairs body assembly

2640 ~ 3600mm passenger stairs body assembly is mainly composed of upper and lower longitudinal beam, step fixing frame, step plate, etc. The ladder body structure is vertical plate change. When the boarding stairs go up and down, the upper and lower stairs move parallel on four sides, and the height of the step changes from 140 ~ 200mm. The two sides of the upper and lower frames are load-bearing beams, which are made of 100×80×5mm and 80×40×3mm seamless rectangular tubes, respectively. The step fixing frame is welded with 40x40x4 Angle steel and connected to the ladder body and the lower longitudinal beam frame with pins. The step plate is pressed with δ=4mm non-slip pattern aluminum plate. When the platform rises to 3600mm, the Angle between the ladder body and the ground is 39°.
