ABSTRACT:
A semi automatic twistlock for engagement with corner castings of ISO containers is operated by a cable. The cable extends around a shaft journalled in a housing, to rotate the cones that arc fixed to opposite ends of the shaft. The cable is extended or retracted though an operating channel and is biased to the retracted position by a spring coupled to the cable on an opposite end of the cable. The cable has a collar which can engage with a first or second stop formed in the operating channel or can remain disengaged in the fully retracted position to thereby permit selective positioning of the cones relative to the shaft.
