Abstract: A locking mechanism for securing a container to a truck chassis is provided and includes a manually reciprocating locking member movable in a piston-like fashion through a housing from a retracted position within the housing to an extended position within a slot of a corner casting in an adjacent container. The reciprocating member is also rotatable and includes an eccentric locking pin to adjust the location of the locking pin to compensate for dimensional variations and to enable the locking pin search for the locking slot of a corner casting by moving between several positions.

Abstract: A chassis lock to secure a container body to a trailer chassis includes a bolt comprising upper and lower telescoping sections, the upper section having a head member received in a cavity in the container body and shaped so that rotating the head bolt locks the body to the chassis. The head member is rotated through the lower portion which is vertically displaceable and lockable in two rotatably different positions by a plate welded thereto that locks into a slot in the chassis in those two positions.
