Unplugged Liebherr for Dutch locks: low-noise sheet piling insights for engineers
Reviewed by Tom Sullivan
First reported on The Construction Index
30 Second Briefing
De Klerk Werkendam is installing 162 new 23m sheet piles in compacted sand at the Brouwersdam sluice locks using a Liebherr LR 1130.1 unplugged electric crawler crane mounted on an electric pontoon. The crane can operate directly from shore power or its own battery, while the pontoon uses electric drive, electric spud piles and a hybrid system with battery storage and solar panels, leaving only the sheet pile vibrator’s hydraulic power unit on diesel. Noise levels are low enough that, at 16m, sound pressure is comparable to normal conversation, materially reducing acoustic impact on site.
Technical Brief
- High-performance sheet pile vibrator was specified to overcome driving resistance in compacted sand strata.
- LR 1130.1 unplugged also handled barge-based materials logistics, reducing separate lifting plant movements on water.
- Electric pontoon’s spud piles provide precise vertical positioning, limiting barge drift and collision risk at the locks.
- Hybrid pontoon system with solar-charged battery storage reduces refuelling operations and associated marine handling hazards.
- Shore-power operation removes exhaust emissions in confined lock approaches, improving air quality for deck crews.
- Crew reported strong preference for low-noise plant, supporting communication clarity and reducing hearing protection burden.
- With only the vibrator HPU on diesel, hot-surface and fuel-spill ignition sources are materially reduced on deck.
- Similar low-noise, low-emission piling spreads are increasingly relevant for lock, bridge and urban waterfront refurbishments.
Our Take
Liebherr appears frequently in our Infrastructure coverage, from Dutch works like Brouwersdam to UK crane fleets at Lee Lifting and Delden Cranes, signalling that contractors are standardising on its kit for both heavy civil and urban lifting applications.
Installing 162 sheet piles of 23 m length at sluice locks in the Netherlands pushes cranes into high-load, long-reach duty cycles where noise and emissions are closely monitored, so the ‘unplugged’ configuration is likely being treated as a live test case for low‑impact marine and flood‑defence works.
