The T type PBB consists of tunnel and sliding sideway (including cabin and short tunnel and its hydraulic elevation column)
1. Tunnel: it is fixed and connected to building. This tunnel can be designed much bigger than normal movable PBB. Like our T PBB in Royal terminal of Riyadh, the WxH is 2500mm x 2700mm
2. Sliding sideway, this part can vertically and horizontally move (as attached), but can not rotate. So T type PBB can only dock to the aircrafts parked at fixed stop bar.
