Lock to secure vehicle in position for loading - has wedge, which pivots into position, at the end of its movement to required wheel

摘要

The lock is formed by a wedge (9), which is mounted to pivot around an axis (10), carried by a support (11). The support can be moved along guides (12), which extend parallel to the rolling tracks, which carry the wheels (14) of the vehicle (2). A drive (19) is fitted to drive the support (11) and the wedge (9) into the required position, by the motor (19b) and the lead screw (19a). The drive also operates the pivoting action of the wedge around its axis, by automatically converting the translation movement of the support into rotational movement, when the required position is reached. USE/ADVANTAGE - It automatically provides a reliable and repeatable locking action under a wide variety of conditions.
