Operating Manual GMK6300L 3 112 xxx en 2 - 11

Lifting loads simultaneously with two cranes is particularly dangerous.
Carry out this type of work with special care.
Always set the load down when there is a break in work, and never leave the
truck crane whilst a load is raised.
Whenever you leave the truck crane, secure it against unauthorised use.
After a lightning strike, always have Manitowoc Crane Care check the truck
crane 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 overhead power lines as
well as oil, gas or other pipelines is dangerous and requires special
precautionary measures. Please observe the instructions in the section
titled
Crane operation under special operating conditions in the Safety manual and
the respective national regulations.
Testing the truck crane by lifting an excessively heavy load (overload testing)
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.
Ramming or pulling sheet-pile walls, sheet piles, beams etc. can damage
the mobile crane or cause it to tip over.
