Liebherr
LR 1600/2
A 600-metric-ton lattice crawler with the full Liebherr derrick package, VarioTray suspended ballast, and walk-with-load capability on tracks. Production discontinued in 2021 with 223 units built worldwide — Coldfoot keeps the LR 1600/2 fully operational for the lifts where a crawler is the right answer.
The Crawler We Built the Fleet Around.
Some lifts require a crawler. The pick walks between locations on a tight site. The radius is too long for an outrigger crane to reach with capacity. The schedule includes dozens of similar picks in sequence and the resetting cost of an outrigger-based mobile would kill the project economics. That's where this crane earns its place.
The LR 1600/2 is the second-generation 600-metric-ton class crawler from Liebherr. Production ran from 2008 to 2021, with 223 units delivered worldwide. It was succeeded by the LR-1700.1, which Liebherr positions explicitly for wind turbine erection. The 1600/2 is a more flexible machine — it does the wind work the 1700 does, but it does refinery turnaround, SMR placement, bridge work, and heavy industrial just as readily, and with a smaller transport footprint.
How Coldfoot Positions This Crane
The wind erection market in North America has consolidated around the LR-1700.1 and a handful of equivalent-class crawlers. Coldfoot does not chase those projects — our brand line is "we don't do wind erection — we do wind maintenance." The LR 1600/2 sits on our yard for the lifts where a 600-mt crawler with a derrick package is the engineering-correct answer, regardless of the industry segment.
Refinery and petrochemical turnaround work is the dominant use case. Reactor replacements, column tail-outs, condenser placements, and modular pipe-rack lifts at sizes the all-terrain fleet can't reach with capacity at radius. Small modular reactor module placement is the emerging second category — SMR vessels are crawler-correct loads on tightly scheduled site builds. And on the maintenance side of wind, when a tower replacement or major-component swap requires a 750-ton class crawler, this is the right tool.
600 Metric Ton. 750 US Ton. The Honest ANSI Re-Rating.
Crawler cranes in this class are predominantly tipping-limited at production radii — that's the engineering basis Liebherr designs to, and it's what lets the metric-to-ANSI conversion deliver a clean capacity increase across most of the working envelope.
Under European DIN, mobile and crawler cranes rate at 75% of tipping load. Under US ANSI/PCSA, they rate at 85%. That's a 13.3% theoretical capacity increase on the same machine, before factoring the metric-to-short-ton conversion (×1.1023). Combined theoretical multiplier: 1.245.
For the LR 1600/2 across most of its SL and SDB configurations at production radii, the machine is genuinely tipping-limited and captures most of that conversion. That's how the published 600 metric ton class is honestly framed as 750 US ton on the Coldfoot yard. Some chart regions at extreme boom angles or maximum-load short radii bump into structural limits — the same as every lattice crawler — and the actual ANSI gain there is closer to 10–11%. Coldfoot's LICCON lift studies are configured against the actual chart utilization, not the nameplate class, so the rating discussion stays in the engineering room where it belongs.
VarioTray — Why Suspended Ballast Matters
The VarioTray is Liebherr's scalable suspended counterweight system. The tray hangs off the derrick boom on a separate lift line; counterweight slabs stack onto the tray in field-adjustable increments. The tray's lever arm changes with radius — short radius pulls the tray in close, long radius lets it swing out farther — which means counterweight effectiveness scales with the lift instead of staying fixed.
Operationally that translates into two things. First, the crane is rated for lifts that a fixed-ballast crawler in the same class can't reach with the same capacity at radius. Second, the VarioTray's stack-and-pin system means counterweight changes happen on the ground in hours, not days — a meaningful schedule advantage on complex multi-pick scopes where the lift study calls for different counterweight loads at different pick radii.

One Crane, the Full Kit.
The LR 1600/2's configuration system follows the standard Liebherr crawler nomenclature: S for main boom, L for light extension sections, D for derrick boom, B for suspended ballast (VarioTray), W for fixed counterweight, F for fixed jib, and N for luffing lattice jib. Coldfoot's LR 1600/2 fleet runs with the full configuration kit on the yard.
Lattice main boom in standard configuration. Heavy and light sections combined for radius performance up to 158 m max length.
Main boom with derrick boom and suspended ballast tray. The standard heavy-lift configuration — captures the full capacity benefit of suspended counterweight.
SDB with additional fixed (carbody and slewing-platform) counterweight stack. Maximum capacity at production radii.
158 m main boom with 30 m derrick, VarioTray, and full ballast package. The maximum-envelope configuration for hub-height wind picks and tall-column refinery work.
Main boom with fixed lattice jib at 0° offset. Used when vertical reach matters more than luffing flexibility.
Main boom with luffing lattice jib. Reach over obstacles, building-edge lifts, and process-vessel placement at extended radius.
The Lifts That Call for This Crawler.
Refinery & Petrochem Turnaround
Reactor replacement, column tail-out and lift, condenser exchange, and modular pipe-rack installation during scheduled and unscheduled refinery turnaround. Walk-with-load capability eliminates resetting between picks on multi-pick scopes.
Small Modular Reactor Modules
SMR pressure vessel and reactor module placement at scheduled site builds. The SDB and SL13DFB configurations provide the capacity-at-radius needed for single-pick critical lifts on confined nuclear sites.
Wind Maintenance & Major Component
Tower replacement, gearbox and main-bearing exchange, and blade replacement work at hub heights where the AT and wheeled-lattice fleet doesn't have the reach with capacity. The crawler maintenance counterpart to Coldfoot's wheeled wind fleet.
Bridge & Heavy Infrastructure
Bridge girder lifts, pre-stressed concrete element installation, and modular infrastructure placement. Walk-with-load lets the crane sequence picks across a long pour without breaking down between locations.
Datacenter & Hyperscale Capital Builds
Modular datacenter section placement, large transformer setting, chiller and rooftop generator installation at hyperscale facility builds. The crawler's track-mobile footprint covers multi-building sites without re-mobilization.
Battery Storage & Substation Builds
BESS container placement, large-format transformer and reactor installation at utility substation builds. Multi-pick repetitive lifts where walk-with-load eliminates the outrigger reset penalty.
Production Discontinued. Operational on Our Yard.
223 LR 1600/2 units were built worldwide between 2008 and 2021. The model line was replaced by the LR-1700.1, which Liebherr markets specifically for wind erection. The 1600/2 remains a more flexible heavy-lift platform — more applications, smaller transport footprint, lower mobilization cost — and Coldfoot keeps ours running.
The Coldfoot LR 1600/2 fleet runs the full configuration kit on the yard: SL main boom sections through 158 m, the 30 m derrick package, VarioTray with the full ballast stack, fixed and luffing lattice jib systems. Service is in-house, parts inventory is maintained against the active fleet, and LICCON lift planning is generated for every critical-lift scope before mobilization. Operating from Billings with satellite yards across the central USA energy corridor — New Mexico, Wyoming-Colorado border, Midland TX, Austin TX.
