摘要

The height-adjustable agricultural trailer coupling has locking bolts (11) in the coupling support (10) engaging recesses in the vertical, vehicle mounted guide tracks. The bolts are moved into or out of the recesses by guide plate control curves (13). The guide plates (12) are ficed to a guide bush (16), spring biased in the bolt locking position, which is selectively engaged or disengaged to an actuating shaft (17), arranged concentrically within the guide bush. ADVANTAGE - Easy handling, and semi-automatic locking.
