NATO Supply Class 3940 is a classification within NATO Supply Group 39, which is dedicated to Materials Handling Equipment. Specifically, Class 3940 focuses on Blocks, Tackle, Rigging, and Slings.

Blocks refer to pulley systems used for lifting and moving heavy loads. They are typically made up of one or more sheaves (wheels with a grooved rim) that are mounted on a frame. Blocks are commonly used in conjunction with ropes or chains to create mechanical advantage and facilitate the lifting or pulling of heavy objects.

Tackle refers to the equipment used in combination with blocks to create a lifting or pulling system. This can include ropes, chains, hooks, and other accessories that are used to secure and manipulate the load.

Rigging refers to the process of setting up and configuring the equipment required for lifting or moving heavy objects. This can involve the selection and arrangement of blocks, tackle, ropes, and other components to ensure safe and efficient lifting operations.

Slings are flexible straps or ropes used to support and secure loads during lifting or moving operations. They are typically made of strong materials such as nylon, polyester, or wire rope and are designed to distribute the load weight evenly to prevent damage or accidents.

In summary, NATO Supply Class 3940 encompasses the equipment and accessories necessary for lifting, moving, and securing heavy loads. This includes blocks, tackle, rigging, and slings, which are essential components of materials handling equipment in various industries and military operations.
