The vertical ribs are clamped on the bottom plate 211 to prevent the whole pedal (pedal body 130) from rotating around the round steel 222, so that the pedal is more stable when being stepped on by an operator.

According to the utility model discloses a running-board assembly and hydraulic support's embodiment, running-board assembly detachably locates the tip of support base, and owing to dodge equipment or change working face when hydraulic support, when its position need change, aircraft nose and tail department can not align with other hydraulic support, have the dislocation, through setting up the running-board assembly, make things convenient for the staff to walk between the frame, to a great extent has reduced the staff and has stepped on empty possibility. The pedal assembly has the advantages of compact structure, firmness, durability, no need of changing the original structure of the bracket base and easy disassembly.
