4 Inspection, maintenance, repair and end of use
Joker hooks must be checked for defects before each use. If you detect
defects, the joker hooks must be set aside.An authorized person must
perform the check according to the employer’s specified inspection inter-
val, but at least once per year. Depending on the usage and operational
conditions, interim inspections may also be necessary. The inspections
must be documented according to DGUV rules 100-500. Additionally,
all metallic fittings must undergo crack inspection at least once every
three years. The inspection must be done according to EN 10228 Part 1
(Magnetic powder testing - “fluxes”) or Part 2 (Penetration Test). After
first use, an authorized person should make special inspections after
damage or special incidents that may affect the load capacity. An excep-
tional check is to be carried out by a suitably qualified person following
damage or a special occurrence which may affect the carrying capacity.
