A.S.P.
Lifting device for strollers and disabled facilities on passenger boarding bridges
The A.S.P. is an inclined plane lifting device useful for bringing baby strollers and facilities for disabled people to the cabin of passenger boarding bridge during landing operations. Basically, the stroller or chair for the disabled is expected to be carried near the PBB service door to be delivered to passengers near the aircraft door.
Other Advantages
In addition to being used as a lifting device, the A.S.P. system has an additional advantage: it can be used as a normal slide for Ramp services, for example to remove cleaning bags and blankets/pillows.
Using the sliding tray, on the other hand, it can be used to move the trolleys which can gradually go down in a row.
