Abstract

Containers loaded on trailers are fastened using a locking device called a twist lock, which is manually operated. There have been instances where a container can fall off a tractor-trailer as a result of improper or inappropriate locking or unlocking. In this paper, we discuss the weaknesses of the locking mechanism of existing twist locks. This paper suggests a new design for an automatic locking mechanism that can be used to develop a better locking system and reduce the risk of container loss. Finite element analysis was also conducted to identify the structural stresses on each component; it was determined from the finite element analysis results, under each load condition, that the minimum safety factor was 1.06-2.41 for each part. Thus, it was discovered that the components had a structural intensity that did not exceed the yield strength.
