Abstract
An arrangement for locking a freight container to a wheeled base in which spring-loaded clamping bolts are located on the base and engage brackets on the freight container with both form and force linkage. Each of the clamping bolts is provided with a locking head and is changeable from a clamping position to a release position by a rotary lifting motion with the use of a grooved curve guide. A pressure-charged spring-loaded piston is rotatable relative to a clamping bolt so that the clamping bolt is axially displaceable on the piston. The grooved curve guide is located between the clamping bolt and the piston, and two opposite power sources apply the relative motion of the clamping bolt and the piston along the grooved curve guide. The two power sources can be actuated independently of one another, and one of the power sources is a pressure chamber located between the clamping bolt and the piston for movement of the clamping bolt into final position of the grooved curve guide, corresponding to the locking and clamping position.
