Rollover Protective Structure
(ROPS), Falling Object Protective
Structure (FOPS)
The ROPS/FOPS Structure (if equipped) on your
machine is specifically designed, tested and certified for
that machine. Excavators are not equipped with ROPS
structures. Any alteration or any modification to the
ROPS/FOPS Structure could weaken the structure.
This places the operator into an unprotected
environment. Modifications or attachments that cause
the machine to exceed the weight that is stamped on
the certification plate also place the operator into an
unprotected environment. Excessive weight may inhibit
the brake performance, the steering performance and
the ROPS. The protection that is offered by the ROPS/
FOPS Structure will be impaired if the ROPS/FOPS
Structure has structural damage. Damage to the
structure can be caused by an overturn, a falling
object, a collision, etc.
Do not mount items (fire extinguishers, first aid kits,
work lights, etc) by welding brackets to the ROPS/
FOPS Structure or by drilling holes in the ROPS/FOPS
Structure. Welding brackets or drilling holes in the
ROPS/FOPS Structures can weaken the structures.
Consult your Caterpillar dealer for mounting guidelines.
Other Guards (If Equipped)
Protection from flying objects and/or falling objects is
required for special applications. Logging applications
and demolition applications are two examples that
require special protection.
A front guard needs to be installed when a work tool
that creates flying objects is used. Mesh front guards
that are approved by Caterpillar or polycarbonate front
guards that are approved by Caterpillar are available
for machines with a cab or an open canopy. On
machines that are equipped with cabs, the windshield
should also be closed. Safety glasses are
recommended when flying hazards exist for machines
with cabs and machines with open canopies.
If the work material extends above the cab, top guards
and front guards should be used. Typical examples of
this type of application are listed below:
• Demolition applications
• Rock quarries
• Forestry products
Additional guards may be required for specific
applications or work tools. The Operation and
Maintenance Manual for your machine or your work
tool will provide specific requirements for the guards.
Consult your Caterpillar dealer for additional
information.
