1.1.1 Checking the guard strips
The figure shows the main boom on a GMK5250L truck crane.
Other GMK models have a similar arrangement of guard strips (1) on the
upper surface of the telescopic sections.
The guard strips (1) are
replaceable parts that must be checked regularly.
Check
• Check all guard strips (1) on all telescopic
sections for damage, wear and formation of
grooves by the hoist rope.
Turn if necessary
You can turn the guard strip, but only when
the bottom of the groove lies significantly
above (X) the telescopic section (2).
• (A) – Remove all screw connections (3).
• Remove the guard strip (1) and clean the
guard strip and the top surface of the
telescopic section.
• (B) – Turn the guard strip (1) by 90° and
fasten all screw connections (3).

Risk of damage to the telescopic sections and hoist rope!
The hoist rope can form grooves in the guard strips when the crane is used
intensively. The hoist rope and telescopic section will be damaged when
the groove depth reaches the metal of the telescopic section.
You must therefore turn or replace the guard strips in time (1).
