Bridge erection, plant outages and industrial tandem lifts — sized by SWL at radius, boom/jib geometry and ground bearing pressure, then commissioned with ASME B30 documentation.
Side-by-side parameters procurement and lift planners use when choosing between a mid-class crawler and a heavy-lift lattice package for the same jobsite pad.
| Parameter | M-220 Lattice Crawler | M-650 Heavy Lift |
|---|---|---|
| Rated capacity class | 220 t | 650 t |
| SWL @ 24 m radius | 86 t | 214 t |
| Main boom max | 84 m | 108 m |
| Fixed jib option | 18–36 m | 24–48 m |
| Engine | 298 kW Tier 4 Final | 447 kW Tier 4 Final |
| Ground bearing (std mats) | 1.8 kg/cm² | 2.4 kg/cm² |
| Counterweight kits | 4 modular packs | 7 modular packs |
| LMI / ATB | Standard | Standard + dual-winch interlock |
