Protection from Falling or Flying Objects
On work sites where there is a danger that falling or flying
objects may hit the operator's cabin select a guard to match the
operating conditions to protect the operator.
Working in mines, tunnels, deep pits or
on loose or wet surfaces
could produce danger of falling rock or hazardous flying objects.
Additional protection for the operator's cabin could be required in
the form of a FOPS (Falling Object Protective Structure) or
window guards.
Never attempt to alter or modify any protective structure
reinforcement system, by drilling holes, welding, remounting or
relocating fasteners. Any serious impact or damage to the
system requires a complete integrity reevaluation.
Reinstallation, recertification and/or replacement of the system
may be necessary.
Contact your DOOSAN distributor for a
v
ailable safety guards
and/or recommendations to prevent danger of getting hit by
objects that could strike the operator's cabin. Make sure that all
other work site crew members are kept well away from the
excavator and safe from possible hazards.
For breaker operation, install a front guard and apply a
lamina
ted coating sheet to the front glass. Contact your
DOOSAN distributor for recommendations.
When carrying out demolition or cutting op
eration, install a front
guard and top guard, and apply a laminated coating sheet to the
front glass.
When working in mines or quarries where there is a danger of
falling rock, ins
tall FOPS (Falling Objects Protective Structure)
and apply a laminated coating sheet to the front glass.
If any glass on the machine is broken, replace it with new glass
immediately.
