Roll Over Protective Structure (ROPS)
The operator's cabin is a ROPS certified structure for protecting
the seat-belted operator. It absorbs the impact energy of a
rollover impact. Do not allow machine weight (mass) to exceed
certified value on certification plate. If weight is exceeded, the
ROPS structure will not be able to fulfill its safety function.
Do not increase machine weight be
yond certified value by
modifying machine or by installing attachments on machine. If
weight limit of protective equipment is exceeded, protective
equipment will not be able to protect operator, and operator may
suffer injury or death. Always observe the following:
• This machine is equipped with a protective structure. Do
not r
e
move protective structure and carry out operations
without it.
• Never modify the operator’s cabin by welding, grinding,
drilling holes
or adding attac
hments unless instructed by
DOOSAN. Changes to the cabin can cause loss of
operator protection from rollover and falling objects, and
operator may suffer serious injury or death.
• When protective structure is damaged or deformed by
falling objects
or
by rolling over, its strength will be reduced
and it will not be able to properly fulfill its function. In these
cases, always contact your DOOSAN distributor for advice.
Never repair a ROPS cabin.
• Always wear your seat belt when operating machine.
