Rollover Protection systems

A Comprehensive Miniguide into Roll Over Protection Systems

When you’re working with heavy machinery like tractors and bulldozers, adequate protection from tip overs and overturns is one of the most important things to consider. In a nutshell, roll over protection systems are not unlike the roll cages you see on the interior of cars and bakkies.

Roll Over Protection Systems (ROPS) come in different configurations, catering to both the interior and exterior of a vehicle. The external Ndlovu ROPS protects both the vehicle and operator when rolling at speeds of up to 120km/h, while also offering a shield against falling objects(F.O.P.S) , on a single cab and ROPS only for double cab. Marven Equipment then offers an internal Ndlovu ROPS , serving as a light duty ROPS, then lastly Marven Equipment has created the Ndlovu Prime , The strongest of 3 Ndlovu ROPS’s , certified to go underground as a people carrier.

To give you a better understanding of what ROPS can do for you and your employees, we’ve created this handy miniguide into roll over protection systems.

A Brief History of Roll Over Protection Systems

Roll over protection systems first appeared in Sweden in the 1950s and were developed to protect tractor drivers when their vehicles would roll over or flip backwards.

In the decades since their invention, roll over protection systems have been subjected to and regulated by several agencies, government organisations, and laws – including the OSH Act. These regulations ensure that ROPS used in specific environments have the needed strength and energy absorption qualities to offer the best protection possible.


Let’s take a look at some of the differences between internal and external roll over protection systems.

Internal Roll Over Protection Systems

Internal ROPS are fitted inside the cabs of the vehicles they protect. These types of internal ROPS you install in your vehicles will ultimately depend on several factors, including which mine are you going on to , the danger level of your job ,vehicle make and model. This is to ensure the best possible protection for your vehicle and its operators. The Ndlovu internal ROPS is made from smaller pipes and is classified under light duty ROPS.

If you’d like to get more insight into the internal ROPS your operation would need, reach out to us – our specialists will be more than happy to assist.

External Roll Over Protection Systems

Unlike their internal counterparts, external roll over systems are designed to offer maximum protection against harsh rolls, unexpected overturns, and unforeseen falling objects. Marven Equipment’s certified Ndlovu External ROPS are designed to protect vehicles and operators from roll speeds of up to 120km/h.

The point of these external systems is to protect machine operators and drivers while limiting the damage sustained in the vehicle’s cab. Together with their internal counterparts, you can rest assured that our roll over protection systems will offer the level of protection needed for successful projects and operations.

Final Thoughts

ROPS are essential features for vehicles in several industries, mainly construction, forestry, agriculture, and mining. Regardless, their versatility makes them perfect for keeping your employee safe !
