The mobile crane landscape is on the brink of a transformation
with the introduction of the Mercedes OM 936 engine into the mighty Franna Pick
and Carry Crane, set to redefine the performance and environmental footprint of
all mobile cranes. Slated for release in July 2024 in all Franna crane models,
this cutting-edge engine represents a strategic shift towards cleaner and more
From July 1st 2024, Australia will enforce Australian Design
Rule (ADR) 80/03,
which aims to decrease the amount of noxious emissions released from heavy
vehicles. Australia bases its standards off the European Union onroad
Going beyond adherence to just the current
Australian emission standards, Franna is forging ahead, eyeing the future by
aligning with the forthcoming ADR 80/04 standard scheduled for introduction in
November 2025, modeled after the European Euro VI onroad standards.
But Franna’s journey didn’t stop
there. Due to Franna's growing global presence, the quest for an engine
complying with both the rigorous European Union nonroad standards and the
stringent USA EPA Standards became imperative. This presented a formidable
challenge, considering the EU and USA impose far more exacting standards
compared to Australia. Presently, the EU adheres to Euro VI standards for
onroad vehicles and Stage V standards for nonroad vehicles, while the USA
mandates Tier 4 Final standards for both onroad and nonroad vehicles. For
reference, a mobile crane falls under the category of nonroad vehicles owing to
its extensive 70% utilisation onsite.
Franna engineers collaborated closely with
Penske, the Australian dealer for Mercedes-Benz engines, resulting in the
selection of the OM 936 engine, which meets the demanding criteria of EU Stage
V, US Tier 4 Final, and ADR 80/04. The OM 936 engine is also available compliant with the Euro
VI onroad standard, although the Stage V nonroad standard is deemed by the EU to be the best standard
for a mobile crane application, and this has also been accepted by ADR.
While other engines were considered by Franna,
the Mercedes was once again chosen as it has shown proven reliability since its
introduction in 2003, and the OM 936 had over twice the engine braking
performance of other engines evaluated without the need to add the additional complexity
and heat load of a transmission retarder.
The first Mercedes OM 936 engine made its
way into Australia in 2015 with Liebherr cranes as a nonroad Stage V and has been a
staple onroad Euro VI compliant engine in trucks and buses ever since.
Clayton McPherson, Principal Engineer for
Franna explains “The choice of the Mercedes OM 936 engine is a deliberate move
toward meeting emissions standards not just for now, but also the foreseeable
future, while maintaining the high-performance and quality Franna is known
The Mercedes OM 936 engine signifies more
than just an upgrade for Franna cranes; it symbolises a commitment to
sustainability, innovation, and growth.
