    Finning engine testing investment: reliability and rebuild insights for engineers

    Finning engine testing investment: reliability and rebuild insights for engineers

    First reported on The Construction Index

    30 Second Briefing

    Finning UK & Ireland has invested £200,000 in advanced Cat engine testing, including a new £160,000 high‑power dynamometer at its Cannock headquarters to certify build quality, strength and power for engines overhauled at its component rebuild centre. The dyno cell collects detailed power, torque and load data in a controlled environment to validate engines for Cat Certified Rebuilds and customer Self Service Repair Options, with settings tuned for fuel economy and reliability. The Cannock installation sits within a new 1,230 m² Rebuild Centre of Excellence being built to handle rising demand for full machine rebuilds and major reconditions.

    Technical Brief

    • Professional-grade dyno equipment is explicitly made available to customers using Cat Self Service Repair Options.
    • Test cell operation focuses on validating safe performance under maximum load conditions in a controlled environment.
    • Data acquisition targets power, torque and force outputs to confirm engines meet specified performance envelopes.
    • Dyno-based diagnostics are used to fine-tune engines for reliability, not only headline power output.

    Our Take

    Finning’s engine testing and Rebuild Centre of Excellence in Cannock align with the recent Finning Power Rental generator rebuild programme in Dublin, signalling a coordinated push to extend life and reliability of Cat power assets across the UK & Ireland fleet rather than relying on new-build capacity.

    Across our Infrastructure coverage, Finning and Cat appear frequently in relation to both rental power and ultra-class mining trucks, suggesting that improved engine test capability in Staffordshire could indirectly support uptime and warranty confidence for high-value fleets such as the Caterpillar 797 units supplied via Finning.

    For UK and Ireland contractors, enhanced in‑house testing tied to the ‘Rebuilt and Ready to Go’ offering likely shortens turnaround times for critical engines, which can be material on major infrastructure jobs where temporary power or heavy plant availability is a key programme risk.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
