Crane Features 

• VarioBase System: Automatically and variably monitors outrigger base extensions, calculating live lifting capacities based on actual stability and footprint.

• Outrigger & Safety Monitoring: Standard automated outrigger status detection, ballast monitoring, and global safety standard compliance (ASME B30.5, EN 13000, GOST, AS).

• Telescoping Technology: Uses a reliable rope-pull telescoping mechanism with two distinct modes (power mode or length mode).

• Operator Cabin: Extra-wide and tiltable up to 20° backward for optimal overhead load visibility, paired with a flat deck and extendable platform for safe access. 

• ECOmode: Manages engine speed to reduce fuel consumption and noise emissions during operations.
