Model: LS-1018 (sometimes referenced as “450 ton” class) — e.g., one listing: “450 Ton Used LINK-BELT LS1018 Crawler Crane”.
Manufacturer: Link-Belt (in some sources in conjunction with Sumitomo Link-Belt)
Type: Lattice-boom crawler crane.
Rated capacity: ~450 metric tons (≈496 US tons) (per one source) for the LS-1018.
Operating weight / transport loads: one spec sheet gives a base crane weight for the model family at approx 88,305 lb (40,055 kg) for one configuration.
Boom lengths: For comparable models (e.g., lattice boom crawler series that includes LS-1018) boom ranges like 55-285 ft (16.76-86.87 m) are shown.
Track & undercarriage: Example data: track shoes 44 in (1.12 m) width, side frames etc for similar model in series.
Ground bearing pressure: Example 14.09 psi (0.9915 kg/cm²) for a related model in the series.
Load charts: Many load radius vs boom length charts available for LS-1018. E.g., “Link-Belt LS-1018 Load Chart PDF … is a 450 metric ton rated capacity crawler crane.”
The “450 ton” designation seems to refer to ~450 metric-ton rated capacity, not necessarily exactly 450 US-ton.
The publicly-available spec data is incomplete for many detailed dimensions, transport weights, counterweights, boom combinations.
Always refer to the actual crane’s OEM rating chart, the identification plate, and the serial number configuration — because different boom assemblies, counterweight packages, jibs, etc will alter the specs.
The LS-1018 appears to be an older or legacy model; availability of up-to-date manuals may require contacting Link-Belt or a parts/service provider.
