Product Detail

What is a Semi-automatic Twistlock

A lash semi-automatic twistlock is a specialized locking mechanism designed for securing shipping containers. This type of device comprises two main components: a semi-automatic locking arm and a twistlock mechanism. The semi-automatic locking arm is designed to automatically engage and secure the container when it is in the closed position. The twistlock component is responsible for firmly holding the arm in place, ensuring a secure connection between the container and the locking mechanism. Together, the lash semi-automatic twistlock provides a reliable and efficient solution for container security during transportation and storage.

Parts of a lash semi-automatic twistlock

The lash semi-automatic twistlock consists of six essential components that work together to ensure secure container locking: the body, handle, barrel, locking lug, pawl, and spring. The body is composed of two halves that seamlessly fit together, serving as the housing for all other parts. One half of the body features the handle, enabling users to grip and rotate the lock for operation. Positioned on top of the body is the barrel, which encloses the locking lug. The locking lug extends from the barrel and engages with notches on the barrel extension, effectively securing the barrel in place. Located on one side of the body, the pawl engages with teeth on the bolt carrier, providing a reliable locking mechanism. Inside the body, the spring imparts power and tension to all components, ensuring smooth operation. With these interconnected parts, the lash semi-automatic twistlock guarantees the reliable and efficient securing of shipping containers during transport and storage.

Proceed by using a hammer and punch to create a hole in the center of the opposite end of the metal, with a diameter of around 1/4 inch. Finally, employ a file or grinder to sharpen one end of the metal into a pointed shape.
