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.
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.
I am sometimes asked whether you can extend the life of a leaf chain fitted to a forklift, simply by swapping or reversing ends?
When you buy leaf chain for telehander or forklift manufacturing you will probably find that it arrives in a box. When you receive it, you’ll have to sort it out and add other components to it before using it in the production line. You may have to cut it to length and store the rest. It can be quite a complex, time-consuming process locating all the components from different deliveries, and then assembling them ready for production.
Leaf chain is a type of chain found most commonly on telehandlers and forklift trucks. In both applications it plays a crucial role. Failure of a leaf chain component can result in catastrophic consequences – leading to a loss of production with associated financial implications or even worse, serious injuries to an operator.
