After a lightning strike, always have the truck crane checked by Manitowoc
Crane Care
before you operate the truck crane – even if you do not notice any
impairment to its function. Electronic components may be damaged by a
lightning strike and may fail unexpectedly, either immediately or during
later operation.
Crane operation carried out in the vicinity of live electrical cables as well as
oil, gas or other supply lines is dangerous and requires that special safety
measures be taken. Observe the instructions in the section titled
Crane oper-
ation under special operating conditions
in the Safety manual and the respective
national regulations.
Testing the truck crane by lifting an excessively heavy load (overload test-
ing) is prohibited. This presents the danger of hidden damage that can lead
to severe accidents during subsequent crane operation. If locally applicable
national regulations require the truck crane to be tested by lifting an exces-
sively heavy load (overload test), always first consult
Manitowoc Crane Care.
