A ramp assembly is provided comprising a ramp that is pivotally movable between a fold-in position and a fold-out position through a neutral position, a drive shaft spaced from an axis of pivot of the ramp in a direction perpendicular to the axis, a drive element transmitting rotational force from the drive shaft to the ramp such that rotation of the drive shaft causes movement of the ramp between the fold-in and fold-out positions, and a spring generating a biasing force by being rotationally tensioned, the spring biasing the drive shaft such that the ramp is biased toward the neutral position when the ramp is in the fold-out position and biased toward the neutral position when the ramp is in the fold-in position. A vehicle incorporating such ramp assembly is also contemplated.

Flip-out ramp for vehicle

A method for positioning an access or loading assembly against the fuselage of an aircraft during the loading or unloading process, in which at least two multichannel scanners are oriented toward the aircraft fuselage and disposed above one another at a distance from each other, each with several light emitting units and at least one detector. First, a reference position is determined by using the scanners, then a current position of the aircraft fuselage relative to the access or loading assembly is determined at determined time intervals by the multichannel scanners. The current position is compared with the reference position to determine a deviation. In case of a deviation between the two positions, a signal is transmitted to the control system of the positioning drive for realigning the access or loading assembly and reducing the deviation.
