ROPS Certification
This DOOSAN excavator has an operator's cabin that meets
ROPS requirements. The seat belt must be worn for rollover
protection.
The ROPS certification plate (Figure 25) is found on the left side
of the cabin on most models. It may vary slightly in its location
on some models.
Check the ROPS cabin, mounting, and hardware for damage.
Never modify the ROPS cabin. Replace the cabin and hardware
if damaged. See your DOOSAN dealer for parts.

ROPS − Roll Over Protective Structure complies with
ISO 12117-2:2008.
WARNING
AVOID DEATH OR SERIOUS INJURY
Never modify the operator cabin by welding, grinding,
drilling holes or adding attachments unless instructed by
DOOSAN. Changes to the cabin can cause loss of operator
protection from rollover and falling objects, and result in
serious injury or death.
Protecting Cabin from Falling Object
(Optional)
In a work site where falling objects or flying objects are
1
expected, be sure to install adequate protective devices for
covering the cabin.
When using a breaker, be sure to install the front window
protection guard (1, Figure 26).
