FB Chain
FB Chain (Letchworth) specialises in leaf chains used on forklift trucks and telehandlers. The site manufactures leaf chain anchor bolts, leaf chain kits, chain anchor pins and chain pulleys.
FB Chain Company Profile
A professional chain wear gauge by FB Chain is a replacement for steel or tape rulers that are traditionally used to measure lifting equipment leaf chain wear, but which are difficult to line up and hold steady.
To use, a service technician sets the nominal pitch of the chain and measures over the number of pins displayed on the front of the tool. Integrated V-jaws ensure the tool is positioned correctly, allowing it to accurately compare the chain’s actual length to the nominal pitch length. It also calculates the percentage wear in 0.25% wear increments—from 0 to 4% worn—with a red warning box appearing at 2%.
Suitable for measuring wear on all leaf chains, from 0.325- to 3-inch pitch, the gauge comes with a protective case and a set of instructions detailing how to determine the nominal pitch of a chain and the correct measurement procedure.
The FB Chain Wear Gauge is a tool that accurately measures leaf chain and roller chain wear and indicates the percentage of elongation so you know when it’s time to replace your leaf chain safely. Leaf chain failure, unless it’s the result of a sudden breakage due to operator error, shock load or overload, is normally a gradual process in which the leaf chain or roller chain elongates as it wears. The accumulative effect of leaf chain wear is a significant increase in the actual pitch of the leaf chain.
The FB Chain Wear Gauge has been primarily designed for the measurement of leaf chain or forklift leaf chain wear. It can also be used to accurately measure all leaf chain and roller chain with an imperial pitch ranging from 3/8″ to 3″.
When conducting leaf chain inspections, it is recommended to observe the requirements of:
