    Liebherr mobile tower crane: weight, axle and power changes explained for engineers

    Liebherr mobile tower crane: weight, axle and power changes explained for engineers

    First reported on The Construction Index

    30 Second Briefing

    Liebherr’s new MK 88-4.2E electric mobile tower crane cuts axle loads to under 9.2 tonnes and total weight below 36.3 tonnes, using wider 445/75 R22.5 tyres on aluminium rims to meet stricter road limits in markets such as Australia, Denmark and the USA. A redesigned chassis and segmented, removable counterweight with integrated ballast cylinders allow optional self-ballasting in two or three lifts without an auxiliary crane. The crane can now run electro-hydraulically from 16A, 32A or 63A on-site power or external battery packs, enabling zero‑diesel set-up and lifting where grid capacity is constrained.

    Technical Brief

    • MK 88-4.2E retains the MK 88-4.1E boom system, limiting redesign mainly to chassis and ballast.
    • Counterweight is split into multiple sections, each removable to tune axle loads and transport configuration.
    • Outrigger beams are designed for easy removal, further reducing transport weight for stricter road corridors.
    • Integrated ballast cylinders in the chassis allow full ballast installation/removal without separate hydraulic packs.
    • Self-ballasting sequence uses two or three lifts, governed by distance to the ballast transport vehicle.
    • Electro-hydraulic mode now covers support and ballasting phases, not just lifting operations.
    • Ability to run off 16A site supplies broadens use on constrained urban projects with limited temporary power.

    Our Take

    Liebherr’s focus on reduced power demand for this mobile tower crane sits alongside its recent R 9300 G8‑E electric excavator launch, signalling a push to lower site power draw across both lifting and earthmoving fleets rather than just swapping prime movers.

    Across our Infrastructure ‘Product’ and ‘Sustainability’ coverage, Liebherr now appears frequently with hydrogen, electric and digital offerings, and this low‑amperage crane option complements that by making it easier to run heavy lifting equipment from constrained grid or temporary power supplies on urban and brownfield sites.

    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.
