ABSTRACT:
The locking device is provided with a jaw for receiving a swinging pin or trunnion, e.g. on the side or tail board of a truck or lorry, as well as with a bolt for the jaw opening. It also has a pivotably mounted claw movable by the bolt by means of a cotter gear and this claw grasps said pin as soon as it is in the pivoting region of the claw and forces it into the jaw. The bolt is advanced synchronously with the claw movement. The swinging pin is held by the bolt with supporting of the claw in the jaw.
