Checking after a lightning
strike
If a crane has been struck by
lightning or if it is suspected that a crane has been struck by lightning, the
following points must be checked:
Inspect the wire rope. See “General Product Manual for ABUS
Cranes”.
Move the crane and trolley and listen out for unusual noises made by
the wheels and wheel bearings.
Check the crane completely for the
correct function. In particular, check hoist limit switches, travel limit
switches, overload protection and all the other safety devices. See “General
Product Manual for ABUS Cranes”.
