Probably not the place, but what these hydraulic moves do on the road? I noticed some busses do them too but I never got why.
Hydraulic busses do it to make it easier for people with limited mobility to get on and off. Not sure why a semi would need it, unless it helps with ramp unloading somehow.
For matching the height of a dock.
That makes sense
And I thought it's about increasing stability on the road or something. Thanks!
