5.3 Periodic inspections
Your GMK7450 truck crane has been inspected before delivery.
– Truck cranes used in Germany are inspected in accordance with the regu-
lations of the professional trade association as defined by DGUV
Regulation
52 (BGV D 6) .
– Truck cranes that are to be used abroad are inspected in accordance with
the
regulations
of the respective country. If such regulations do not exist,
they are inspected in accordance with the regulations of the professional
trade association as defined by DGUV Regulation 52 (BGV D 6).
According to German regulations (DGUV), an inspection must be carried
out once a year. The regulations in othe
r countries may prescribe different
inspection intervals. If such regulations do not exist, an inspection should
be carried out by an
expert at least once a year.
These periodic inspections are generally visual examinations intended to
assess the condition of the truck crane and its compone
nts. Their purpose
is to detect defects at an early stage and thus prevent accidents.
Inspections must be carried out on the following, if they are not already
included in the list of periodic mainte
nance work:
– the hydraulic and electrical control and safety devices,
– the rated capacity limiter (RCL),
– the fastening and safety devices of all screwed-on parts,
– the hoist ropes,
– the load hooks (
à Load hook inspection, P. 5 - 20),
– the load-bearing structural steelwork (for tears, deformations, etc.),
including a special check of
all welds.
If damage is found on the steel fabrication, qualified specialists must deter-
mine the extent of the damage using the required material examination
methods. They shou
ld the
n determine what sort of repair should be carried
out.
Prior to carrying out welding work on the truck crane, observe the
à Safety
instructions for welding work
, P. 1 - 4.
The inspector must write a report containing the result of the annual inspec-
tion that was performed and the measures taken to repair any damage.
