LTM 1800
The only hydraulic-boom crane that operates with a lattice derrick. With the derrick deployed, the LTM 1800 becomes the strongest hydraulic-boom crane in the world working at radius — and it still drives to the job under its own power.
Hydraulic Boom. Lattice Derrick. One Crane.
Every other crane in this class makes you choose: hydraulic boom for speed and mobility, or lattice rig for raw capacity. The LTM 1800 is the only mobile crane on the market that runs both.
The telescopic main boom deploys in minutes — fast setup, fast tear-down, drive between picks. Then, when a job calls for serious capacity at extended radius, the same crane accepts a lattice derrick that adds back-stays to the telescopic boom and transforms the lift envelope. With suspended counterweight (the B package), capacity at radius doubles versus standard T configuration.
Why Two Ratings: 970 and 1,000 US Ton
Under ANSI/PCSA, mobile cranes are rated at 85% of tipping load (vs. 75% under European DIN). For pure stability-limited lifts, that delivers a clean ~13% capacity increase when converting from metric to US ton ratings — the math the LGD 1550 captures cleanly at 685 US ton.
The LTM 1800 is different. Across most of its standard telescopic envelope, it's structural-limited , not tipping-limited — the boom material caps capacity before stability does. Side-by-side chart codes from Liebherr's published load tables (PCSA vs. DIN at matched configurations) show ~9–11% actual ANSI boost in standard T configuration, not the full 13%. That puts the honest rating at 970 US ton.
Deploy the derrick and suspended counterweight (T2DB), and the boom transitions to tipping-limited across more of its working envelope. The full ANSI re-rating now applies, and the crane reaches its 1,000 US ton nameplate. The derrick is the differentiator — it's why this crane is the only hydraulic-boom mobile in the world that rates that high.
Telescopic + Derrick + Luffer.
Built Per Lift.
The LTM 1800's configuration system uses T (telescopic) as the base, with optional D (derrick), B (suspended counterweight), N (luffing lattice jib), F (fixed fly), and H (auxiliary boomnose) modules. Coldfoot stocks the full system — every module, every guying point, every counterweight slab.
Standard telescopic main boom operation. Fast deployment for sub-200,000 lb production picks.
Boom stayed on telescopic section 1 with derrick boom. Increases capacity at extended radius.
Boom stayed on telescopic section 2 with derrick boom. Higher boom angle, longer reach configuration.
Telescopic section 1, derrick, and suspended counterweight. Maximum-capacity configuration at intermediate radius.
Telescopic section 2, derrick, and suspended counterweight. The strongest possible hydraulic-boom configuration this crane can run.
Telescopic boom with 161 ft lattice fly jib at 0° offset. Vertical reach without luffing complexity.
Telescopic boom with luffing lattice jib up to 298 ft. Wind turbine work and tall vessel installations.
Telescopic boom stayed for additional back-support, with luffing jib. Higher capacity at long luffer radii.
Telescopic section 2, derrick, suspended counterweight, and luffing lattice jib. The crane's maximum rated envelope.
Derrick configuration with auxiliary boomnose. Secondary lift point for tag-line or fixed-angle work.
The Lift That Calls for This Crane.
Wind Turbine Hub-Height Erection
Nacelle and rotor placement at 100–120 m hub heights using the TN and T2DBN configurations. Telescopic deployment beats crawler walk-in for tight wind site schedules.
Refinery Reactor Replacement
T1DB and T2DB configurations deliver the radius capacity for reactor and column tail-out, walk-in, and final placement during refinery turnaround.
Small Modular Reactor Modules
SMR vessel placement at scheduled site builds. The derrick package unlocks the capacity-at-radius needed for single-pick critical lifts on confined sites.
Bridge & Infrastructure
Bridge girder lifts, infrastructure modular placement, and pre-stressed concrete element installation. Hydraulic boom for rapid relocation between pours.
Datacenter Capital Builds
Pre-fab modular datacenter sections, large transformer placement, chiller and rooftop generator sets at hyperscale facility builds.
Gas Compression Station Installation
Compressor packages, separators, and process skid installation. Self-propelled mobility means the LTM 1800 reaches remote midstream sites faster than crawler alternatives.
One of the Largest LTM 1800 Fleets in North America.
Coldfoot operates a deep LTM 1800 inventory with the full configuration kit — two complete tray-and-derrick packages, the full counterweight stack including suspended ballast, and the heavy-luffer (TN) and fixed-fly (TF) jib systems.
Operating from Billings and satellite yards across the central USA energy corridor — New Mexico, Wyoming-Colorado border, Midland TX, and Austin TX — the LTM 1800 fleet is positioned for fast deployment across wind, petrochem, SMR, and infrastructure projects. LICCON-verified lift planning is generated in-house for every critical-lift scope.
