Who We Work With
Specialist Engine Work for the Industries That Run on Heavy Diesel
The operators who bring work to Franklin Engineering Services are not here for a routine service. They are here because the engine work is complex, the equipment is high-value and they need it done properly by people who know what they are doing. Trucking companies with engines that have done serious kilometres. Earthmoving contractors with machines that cannot sit idle on a job site. Marine operators with vessels that run on schedule regardless of the tide. Agricultural businesses with equipment that has a narrow window to be serviceable and a long off-season to dread.
What connects these customers is not just the diesel engine. It is the pressure to have equipment that performs reliably under sustained load, and the cost of getting it wrong. Franklin Engineering Services understands that. The workshop has been supporting heavy diesel operators across New Zealand since 1975, which means the team has seen virtually every engine platform, every failure mode, and every operating condition the country throws at heavy equipment. That depth of experience is what makes Franklin Engineering Services useful to operators across such a wide range of sectors.

Specialist Support Across Heavy Industry
Different sectors make different demands on diesel engines. The failure patterns on a ferry running year-round look nothing like those of an excavator on a civil site. A generator set under continuous load has its own pressures. Truck and haulage fleets have theirs. Franklin Engineering Services has worked across all of it. The team doesn't just know the engines. They understand the operational context behind the job, which shapes how work gets assessed, what's prioritised, and what a practical repair path actually looks like for your equipment and your industry.
