Luggage chutes and climbing stairs used by staff for maintenance may also be installed. 3.15 service stair stair-step tunnel between a boarding bridge and the apron, which can usually move synchronously with the boarding bridge 3.16 canopy telescoping weatherproof device between the cab and the aircraft door 3.17 inter-ramp short ramp that smoothly transitions the ground steps between tunnels 3.18 safety shoe pressure-sensitive switch placed under the open aircraft door in the fixing state for detecting the rapid downward movement of the aircraft 3.19 emergency lowering action to trigger safety shoe or equivalent detection devices to make the boarding bridge automatically lower in order to protect the aircraft door when the aircraft fuselage suddenly lowers with an amplitude beyond the adjustment capability of the auto-levelling device 3.20 hold-to-run control manual control device. If it is pressed, the boarding bridge will move; if it is released, the boarding bridge will stop moving 3.21 auto-levelling action to automatic adjust the relative height between the cab floor and the aircraft threshold in the fixing state 3.22 height of passenger boarding bridge vertical distance from the midpoint of the front edge of the cab floor to the apron ground 3.23 length of passenger boarding bridge distance between the center of the columns of the rotunda and the front end of the cab floor when the symmetrical center line of the cab coincides with that of the boarding bridge and the boarding bridge is in a horizontal state Note: The length of the boarding bridge structure type shown in Figure 4 is not applicable to this definition.
