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 it comes to forklift trucks and other materials handling equipment that use fixed leaf chains, the saying “A chain is only as strong as its weakest link” is not entirely true, as another weak point is potentially the anchor – where the leaf chain is attached to the lift system.
Installed and maintained correctly, the hard-working leaf chain on your forklift or telehandler will give many years of service. But any industrial leaf chain will suffer from wear or potential environmental damage and should be periodically inspected.
Regular leaf chain inspection is vital for ensuring the safe operation of any form of safety-critical materials handling equipment such as forklift trucks or telehandlers.
Some signs of leaf chain wear are obvious. Turned pins, for example, are easy to spot and are an indication that a leaf chain will need to be replaced as a matter of urgency.
But other forms of leaf chain wear, may be less visible, which means leaf chain needs to be routinely measured to ensure that it is not exceeding the accepted percentage of elongation.
At the same time it is important to bear in mind that there can be an over-reliance on leaf chain elongation when conducting a leaf chain inspection. What is important is to take into account all the operational factors that can have an impact on leaf chain wear.
In this blog post we discuss some of the key considerations that will help to guide your leaf chain inspections and to ensure the safe and consistent operation of your materials handling equipment.
When conducting a leaf chain inspection of any form of safety-critical industrial equipment, there can often be an over-reliance on the measuring of chain elongation.
While chain elongation is a significant factor, it should also be considered in the context of a wide range of other chain wear signs and symptoms including the condition of surfaces, pins and links or the effects of rust.
Regular leaf chain inspection, in combination with an ongoing maintenance programme, will play a crucial role in improving safety and enhancing the service life of your materials handling equipment.
In this blog post we summarise some of the key signs to look for when evaluating the condition of your leaf chain and its component parts.
Tracking chain wear is a vital element of any chain inspection or service of materials handling equipment.
In most cases, leaf chain failure is a gradual process in which the chain elongates as it wears. And the accumulative effect of chain wear is a marked increase in the actual pitch of the chain.
Once your leaf chain has reached, or exceeded, the recommended limit of extension then it's time to take action.
The environments in which leaf chain mechanisms operate can differ widely. And the harsher the environmental conditions, the greater the impact will be on the safety, efficiency and longevity of the chain.
Chain that is used in forklift trucks, for example, can often be compromised by the effects of outdoor moisture, highly corrosive atmospheres or abrasion from sand or grit.
In this blog post we explore the primary environmental factors that can affect leaf chain wear-life and the importance of regular leaf chain inspection in ensuring the optimum performance of your materials handling equipment.
