3. Introduction
A Roll Over Protective Structure (ROPS) is a reinforcement
member(s) installed in to, or on to a vehicle with the intention
of protecting the vehicles occupants in the event of a roll over
accident.

4. Purpose of ROPS
To limit the crushing and deformation of the vehicle roof and
cabin structure during a roll over accident.
 ROPS are life-saving devices that can prevent drivers from
being crushed when a vehicle or tractor rolls over.

5. Rollover Propensity
 Vehicle tendency to roll over = T/2H
where,
T = Vehicle track width
H = Height of center of gravity

6. Types of ROPS
 Internal ROPS

7. Internal ROPS
 Less effect on height of Centre of Gravity
 Less mass for a stronger structure
 Not subject to environmental wear and tear
 Slight compromise on entry/exit of some vehicles.

8. Types of ROPS
 Internal ROPS
 External ROPS

9. External ROPS
 Mounted into the tray of utilities or
surrounding the outside of a cabin structure.
 Add to the height of the vehicle’s center of
gravity.
 Increase the rollover propensity of the
vehicle

10. Types of ROPS
 Internal ROPS
 External ROPS
 Tray type ROPS

11. Tray type ROPS
 Reduces load space and load mass
 Prone to damage from load being carried in
tray
 Limited by tray or its mounts onto chassis (can
be torn off leaving occupants unprotected).

12. Types of ROPS
 Internal ROPS
 External ROPS
 Tray type ROPS
 Cabin type ROPS

13. Cabin Type ROPS
 Reduces risk of injuries
 Prone to damage and environmental wear and tear
 Significantly heavier structure than other types
 Increases propensity to roll over

16. ROPS for Material Handling Equipment
 All rubber-tired, self-propelled scrappers
 Rubber-tired front-end loaders
 Rubber-tired dozers
 Wheel type agricultural and industrial
tractors
 Crawler tractors
 Crawler-type loaders
 Motor graders

17. Performance Criteria
 ROPS should be designed to support at least twice the machine’s
weight.
 The design objective of ROPS shall be to minimize the complete
overturn of equipment
 The design shall provide a vertical clearance of at least 52’’ for the
operator when getting on and off the machine.
 The seat belt shall be properly maintained.

18. Reduce Your Rollover Risk
 Reduce speed on rough ground or in areas where holes
or stumps might be located.
 Reduce speed on slopes where the major hazards are
often unseen depressions, rocks, and stumps.
 When working on grades or slopes, increase stability by
adding from or rear wheel weights to counterbalance
front or rear mounted implements and heavy drawbar
loads.
 Stay clear of ditches, embankments, stumps, rocks, and
other obstacles.
 Turn slowly; sudden turns create an unstable condition
due to centrifugal force.

19. What You Can Do?
 Identify all equipment in your operation.
 Retrofit all material handling equipment without ROPS.
 Check for seat belts.
 Post a reminder on driver’s seat.
 Identify tasks that are prone to vehicle’s rollover.
 Instruct operator to use only vehicles with ROPS and seatbelts.
