How far should the forks be raised to check for the deformation of the forklift chain?

When checking for deformation of the forklift chain, the correct height to raise the forks is crucial for ensuring accurate assessment and safety. Raising the forks 10-15 mm is the appropriate range because this height allows for a clear examination of the chain's slack and overall condition. It is sufficient to observe any wear or stretching that may have occurred without raising the forks too high and risking instability. This distance strikes a balance; it is low enough to maintain control and visibility of the chain while high enough to eliminate the effects of slack that might obscure any abnormalities.

In practice, raising the forks too low may not reveal sufficient detail regarding the chain's integrity, while raising them too high could complicate the inspection process and lead to misinterpretations or oversight of critical issues. Therefore, the measured range of 10-15 mm provides a practical and effective means of checking the forklift chain's deformation while ensuring safety and operational efficiency.
