For the better safety of a driver or operator, agricultural tractors and self-propelled machines are equipped with protective structures: Roll-Over Protective Structures (ROPS); Falling-Object Protective Structures (FOPS).
Protecting the driver and machine in case of overturn
ROPS: A protective structure on tractors and self-propelled agricultural machines which significantly increases safety if the machine turns over. ROPS consists of a frame that rests on the uppermost part of the roll bar, with strengthening ribs to prevent collapse. It may also include diagonal struts and other structural components for maximum rollover protection.
ROPS/FOPS: The frame rests on the uppermost part of the roll bar. ROPS is one element that comprises a structure (the other element being the seat). It should be noted that it does not make sense to equip agricultural tractors with FOPS only, as this would mean only protecting the operator to a relatively small extent. There would be no protection of, for example, the engine hood and many other components.
FOPS: a component of a ROPS that prevents objects from falling onto the cab or rollover structure during normal operations. The object may be a part of the machine, such as an exhaust stack, or something external to the machine being towed. Falling-Object Protective Structures (FOPS) protect from falling objects. FOPS consists of a bar at the top of the cab. The FOPS is perforated to allow air to pass through, but objects will not fall through it.
Benefits of ROPS and FOPS:
Minimizes the risk of injury in case of overturning. Protects from falling objects. Supports the rollover structure to prevent collapse.
Prevents objects from jamming the rollover structure. Protects occupants in other situations such as fire or chemical spills.
ROPS are usually only found on tractors over a certain weight. For example, ROPS are not normally installed on small garden tractors, where the frame is likely to be significantly lighter. The same applies to compact utility vehicles with operator cabs that are too small to provide protection for occupants in case of a rollover.
ROP and FOPS help us to keep our drivers and operators safe. If you are looking at getting yourself one of the latest John Deere models, please visit our website to find out how we can help you.
Tips to buy ROPS and FOPS:
ROPS and FOPS are important safety features, so before purchasing a tractor or compact utility vehicle it is essential to check whether ROPS and FOPS are standard, optional, or not available at all. When you buy the tractor or compact utility vehicle, remember that it does not make sense to install ROPS/FOPS later on as this will require significant modification.
Conclusions: ROPS and FOPS are not mandatory for tractors or compact utility vehicles, but it is recommended to consider the installation of both structures on heavy machinery. ROPS and FOPS significantly increase safety in case of overturning and falling objects. Ensure that the machine has been installed according to manufacturers’ recommendations and be aware that it does not make sense to install ROPS/FOPS later on as this requires significant modification.
Frequently asked questions for ROPS and FOPS:
What are the benefits of ROPS and FOPS?
ROPS and FOPS prevent injuries both for the driver or operator in case of overturning. Furthermore, they protect occupants from falling objects, support the machine’s rollover structure to prevent collapse, prevent jamming of machine parts, and provide protection in other situations such as fire or chemical spills.
What do ROPS and FOPS consist of?
ROPS consists of a frame that rests on the uppermost part of the roll bar, with strengthening ribs to prevent collapse. It may also include diagonal struts and other structural components for maximum rollover protection. The FOPS is perforated to allow air to pass through, but objects will not fall through it.
Where can I find ROPS and FOPS on a construction machine?
ROPS and FOPs may be installed as standard, optional, or not available at all on tractors and compact utility vehicles. However, they significantly increase safety in case of overturning and falling objects. Ensure that the machine has been installed according to manufacturers’ recommendations and be aware that it does not make sense to install ROPS/FOPS later on as this requires significant modification.
Where can I find ROPS and FOPS on a commercial vehicle?
ROPS and FOPS may be installed as standard, optional, or not available at all. However, it is recommended to consider the installation of both structures, especially on heavy machinery where a well-designed rollover protection structure is necessary. Ensure that the machine has been installed according to the manufacturers’ recommendations and be aware that it does not make sense to install ROPS/FOPS later on as this requires significant modification.
What is the purpose of a roll-over structure?
In case of overturning, a well-designed roll-over structure helps to protect occupants from being crushed by heavy equipment or thrown out of the cab. The structure also helps to protect occupants from falling objects or being ejected, supports the machine’s rollover structure, prevents jamming of machine parts, and provides protection in other situations such as fire or chemical spills.
