Grade 70 transport chain fittings as per AS 4344 refer to the components that are used with Grade 70 chain, a high-strength chain that is commonly used for securing heavy loads during transportation. AS 4344 is the Australian Standard that outlines the requirements for the design, testing, and performance of Grade 70 transport chain and fittings.
Some common types of Grade 70 transport chain fittings as per AS 4344 include:
- Clevis grab hooks: A clevis grab hook is a type of hook that is used to connect Grade 70 chain to an anchor point or load. It has a clevis pin that can be removed for easy attachment and detachment of the chain.
- Clevis slip hooks: A clevis slip hook is a type of hook that is used to connect Grade 70 chain to an anchor point or load. It has a spring-loaded latch that can be opened to insert or remove the chain.
- Connecting links: A connecting link is a metal link that is used to join two lengths of Grade 70 chain together. It has a pin or bolt that can be removed for easy attachment and detachment of the chain.
- Shortening hooks: A shortening hook is a type of hook that is used to shorten the length of Grade 70 chain by looping it back on itself. It has a spring-loaded latch that can be opened to insert or remove the chain.
Grade 70 transport chain fittings as per AS 4344 are designed to be used with Grade 70 chain, which has a high working load limit and excellent resistance to wear, corrosion, and deformation. It is important to use the right type of fitting for the intended use and to follow the manufacturer's instructions and the requirements outlined in the standard. Regular inspection and maintenance of the chain and fittings are also necessary to ensure their safe and effective use.
