Loading ramp with bridge plate swivelling on horizontal axis

摘要

The ramp comprises an extension (11) which on its edge facing the bridge plate (1) has a curved extended piece (15) extending over the joint length and has a circle sector shaped cross-section. The extended piece protrudes into a profile (6) fixed to the bridge plate and also extends over the joint length. The profile has a ridge (10) defining the link axle and acting as support for the extended piece. The exterior of the ridge matches the inner radius of the extended piece. The back end of the outer surface (17) of the extended piece has a forward protruding lug (18) cooperating with two stop pieces (8,21) on the profile restricting the extension's swivel movement.
