7 key innovators in the history of industrial chain
Who invented industrial chain? Was it Hans Renold, André Galle, Leonardo da Vinci or perhaps even Imhotep? We look back over the key innovations that laid the foundations for today’s lifting and transmission chain.
When faced with a choice of AL, EL-LL or BL-LH series leaf chain, we almost always recommend handling equipment designers to specify BL series leaf chain due to its superior consistency, strength and availability.
Chain wear and chain stretch both increase the length of leaf chain but it is important to understand the difference and what you are actually measuring when carrying out inspections with a chain wear gauge.
All leaf chain manufacturers will have their own ideas on the best combination of material, heat treatment and process for making good leaf chain but there are certain factors you can rely on to objectively compare quality.
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.
When designing lifting or handling equipment such as forklifts and telehandlers, most design engineers would look to comply with the specific standard for the machine they are designing.
This week, I was very pleased to receive a pack from the British Standards Institute confirming that I am now a member of TC100 which represents the UK on standardisation in the field of power transmission chains, conveyor chains, chain wheels and leaf chain. There are 12 countries with active committees and these look after 15 different standards.
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.
I am sometimes asked whether you can extend the life of a leaf chain fitted to a forklift, simply by swapping or reversing ends?
