Up to 80 ton Telescopic Crawler Crane
Up to 80 ton telescopic crawler cranes combine tracked undercarriages with telescoping booms, enabling them to travel with loads across unstable or soft ground without deploying outriggers. This size class spans compact mini-crawlers rated as low as 1.5 tons through mid-range machines lifting up to 70 tons, covering pipeline assembly, foundation placement, and bridge construction where ground-bearing pressure and mobility dictate equipment choice. The ladder steps up to 80+ ton telescopic crawler cranes for heavier structural work.

Spécifications clés
| Spécification | Plage typique | Signification |
|---|---|---|
| Lifting capacity | 3,307–154,324 lb (1.5–70 t) | Maximum rated load varies widely; compact units handle materials and light structural work, larger models set precast and heavy mechanical equipment. |
| Max reach | 20–76 ft (6.1–23.2 m) | Telescopic boom extension determines working radius; longer reach suits spread-out pipeline or utility installations. |
Comment choisir
Up to 80 ton telescopic crawler cranes suit projects where ground conditions prevent wheeled or truck-mounted cranes from traveling under load, and where outrigger setup time or footprint is prohibitive. Applications include pipeline stringing across unimproved rights-of-way, foundation work on sloped or marshy sites, and bridge assembly over waterways. When lifting capacity exceeds 70 tons or reach requirements extend beyond 76 feet, the 80+ ton telescopic crawler crane class offers greater structural capacity and boom length for heavy civil and industrial construction.
Ce que cette taille peut gérer
- Pipeline section placement across wetlands and uncompacted fill
- Precast foundation element installation on hillside residential developments
- Bridge girder positioning over rivers and drainage channels
- HVAC unit setting on congested industrial sites with limited outrigger zones
- Utility pole and transformer installation along unpaved easements
- Structural steel erection in urban areas with restricted street access
Sécurité et opération
- Load charts account for travel with load; operators must verify ground-bearing capacity and slope angles before moving under load
- Track width and ground pressure distribution determine safe operation on soft soils; wider tracks spread weight but increase transport complexity
- Telescopic boom geometry changes load moment as sections extend; real-time load monitoring systems assist with dynamic lift planning
- Proximity to overhead utilities and underground services requires site surveys; boom length and slewing radius often exceed the machine footprint
Transport et logistique
- Compact models (under 10 tons) often trailer on standard flatbeds or tilt-beds without permits; larger units require lowboy or RGN trailers
- Mid-range machines may exceed legal width when tracked; transport typically involves partial disassembly or specialized permitting
- Self-loading capability varies by model; many require auxiliary cranes or forklifts for trailer loading and unloading
Alimentation
- Diesel engines power both travel and lifting functions; fuel capacity ranges from small daily-fill tanks on mini-crawlers to larger onboard reservoirs on mid-range units
- No external electrical connection required; machines are self-contained for operation in remote or unimproved locations
- Emissions tier compliance varies by model year and manufacturer; Tier 4 Final engines are standard on newer machines
