For bridge construction, you need a truck crane with:
- High lifting capacity (at least 55-75 tons for precast beams)
- Long boom reach (to place beams across spans)
- Good outrigger stability (for heavy lifts)
The XCMG XCT75 (75 tons) or XCT130 (130 tons) are good choices. For very large bridges, you may need a crawler crane instead. Always check the load chart to ensure the crane can reach the required distance and height.
