Inspection of the load hook and top hook
Inspect the hook for deformation, damage, surface cracks, wear and signs of corrosion, as
required, but at least once a year. Actual operating conditions may also dictate shorter
inspection intervals.
Hooks that do not fulfil all requirements must be replaced immediately. Welding on hooks, e.g.
to compensate for wear or damage is not permissible. Top and/or load hooks must be
replaced when the mouth of the hook has opened more than 10% or when the nominal
dimensions have reduced by 5% as a result of wear. Nominal dimensions and wear limits are
shown in table 3. If a limit value is reached, replace the components.

Inspection of the brake
Immediately contact the manufacturer, if irregularities are found (e.g. defective friction disks).
All components of the brake must be checked for wear, damage, discoloration caused by
overheating and for functioning.
Friction disks must always be kept free from grease, oil, water or dirt. Check the bonding of
the friction disks.
