Bernard Hunter’s 90t Liebherr: rough terrain lift advantages for bridge engineers
Reviewed by Tom Sullivan
First reported on The Construction Index
30 Second Briefing
Bernard Hunter has deployed Scotland’s first 90‑tonne Liebherr LRT 1090‑2.1 rough terrain crane, ordered at ConExpo in Las Vegas, expanding its heavy-lift capability on constrained infrastructure sites. The crane’s 47m telescopic boom, 10.5–19m double swingaway fly jib with up to 40° offset, and maximum 66m hook height at 50m working radius give substantial reach for bridge, precast and plant installation work. Standard VarioBase support and an outrigger monitor integrated into the control system allow higher capacities on partial outrigger spreads, critical on tight urban and brownfield footprints.
Technical Brief
- Cab tilts backwards, improving operator sightlines for high lifts and reducing neck strain on long picks.
- Integrated outrigger monitor auto-detects each outrigger’s extension and feeds status directly into the crane control logic.
- VarioBase dynamically recalculates lifting charts for asymmetric outrigger spreads, enabling safe capacity gains on partial setups.
- Rough terrain configuration suits unpaved, uneven construction compounds typical of bridge, precast yard and plant sites.
Our Take
Liebherr appears frequently in our recent coverage for large mining-class equipment like the R 9600 and R 9800 excavators and PR 776 dozers, so Bernard Hunter’s 90 t LRT 1090-2.1 deployment in Scotland underlines how the brand is now spanning both heavy civil infrastructure and mine-scale fleets in the UK-linked market.
With a maximum hook height of 66 m and 50 m working radius, this rough-terrain crane gives Bernard Hunter reach comparable to smaller lattice crawlers but with faster mobilisation, which is likely attractive for congested urban or brownfield infrastructure work common in the UK.
The combination of a 10.5–19 m double swingaway fly jib and 40° offset suggests the unit is well suited to bridge, industrial plant and wind-related lifts where obstructions limit setup options, aligning with the type of complex project work that dominates our 910-item Infrastructure category.
