There’s no one size fits all when it comes to leaf chain anchor bolt nuts. The loads, vibrations and temperatures experienced during operation all impact performance – and some types of nuts are much more durable and easier to adjust than others. Here we break down some of the advantages and disadvantages of each type, depending on application.
Why should I use a Chain Wear Gauge?
Leaf chain is deemed to be worn beyond its safe service life when the nominal pitch length has been extended by 2% to 3%. At this point, the fatigue life of the leaf chain is reduced and the ultimate breaking strength is considerably lower.
Pulleys, also known as sheaves, are an essential item in a leaf chain system. It is a crucial moving part as an incorrectly designed pulley will have a big impact on performance and the working life of the equipment or the chain, or both. Pulleys should be designed to allow the chain free movement as the ram moves up and down. Ideally, they should be designed to last the lifetime of the machine they are being installed on (unless design criteria dictate otherwise).
Leaf chain anchor bolts are a crucial part of a leaf chain assembly – if they are not designed without considering all the relevant factors then they may not conform to industry standards or they may even fail. Here are the main considerations when designing an anchor bolt for use with a leaf chain.
