Lattice Boom Crawler Cranes
Cranes with an assembled lattice boom for heavy and high lifts on civil, industrial and energy projects. The highest capacity per tonne of crane, at the cost of assembly time.
Features
- Lattice sections give high stiffness for low weight, which is what puts capacity at long radius and great height.
- Boom and jib are assembled from sections on site, so the configuration can be tailored to each lift.
- Luffing jibs add height and reach while keeping the load inside the crane's permitted moment.
- Superlift and derrick arrangements extend the load chart significantly and add their own transport and assembly scope.
- Free-fall winches, where fitted, mark a machine configured for duty-cycle work rather than plain lifting.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Maximum rated capacity | 80 - 400 | t | Sets the class, but never the lift plan on its own. |
| Maximum main boom length | 60 - 100 | m | Determines hook height before a jib is added. |
