5.3 Periodic inspections
Your GMK 4100L-1 truck crane has been inspected before delivery.
– Truck cranes used in Germany are inspected in accordance with the
regulations of the professional trade association as defined by
BGV D 6 (VBG 9).
– 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 BGV D 6 (VBG 9).
According to German regulations, an inspection must be carried out once a
year. The regulations in other 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 components. 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 maintenance 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 (

Load hook inspection
, p. 5 - 20),
– the load-bearing steel construction (for cracks, deformation, etc.),
including a special check of all welds.
If damage is found on the steel construction, qualified specialists must
determine the extent of the damage using the required material
examination methods. They should then 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
inspection that was performed and the measures taken to repair any
damage.
