摘要： A ramp assembly includes a ramp movable between a deployed position, a stowed position, and an intermediate position and a drive mechanism comprising a motor configured to move the ramp between the deployed position and the stowed position. The motor has a shunted mode and a non-shunted mode. The assembly further includes a first detecting arrangement configured to detect a position of the ramp and a second detecting arrangement configured to detect a direction of movement of the ramp, with the motor being placed in one of the shunted mode and the non-shunted mode based on the position and the direction of movement of the ramp.

摘要： A mechanism for deploying and aligning a ramp relative to a platform includes a main bearing operatively associated with the platform and rotatable about a main pivot axis; a drive member disposed on the main bearing, the drive member being adapted to drive the main bearing to rotate about the main pivot axis; a rotating member disposed on the main bearing and rotatable about the main pivot axis with the main bearing; and a ramp member rotatably connected to the rotating member at a pivot point eccentric to the main pivot axis. Rotation of the rotating member causes the ramp member to move between a stowed position and a deployed position in an arcuate path about the main pivot axis.
