Dual main beam load-bearing reinforcement: Utilizing two parallel box-type or truss-type main beams connected by cross beams to form a rigid frame, the load-bearing capacity is increased by over 50% compared to single-beam tire-mounted cranes, accommodating lifting requirements from 10 to 50 tons (with some custom models reaching 100 tons)
The span range is extended to 12-30m, making it suitable for lifting extra-long and extra-wide components such as steel structures and precast panels. Tire-mounted mobility: Equipped with multiple sets of pneumatic tires (typically 4-8 wheels), no fixed tracks are required, allowing free movement on hardened surfaces (concrete, asphalt). The minimum turning radius is approximately 5-8m, enabling rapid relocation between work sites (e.g., from a workshop to a storage yard).
Travel speeds reach 10-20 km/h, significantly outperforming the mobility efficiency of track-mounted cranes. Stability system upgrade: Standard-equipped with retractable hydraulic outriggers, which, when deployed during operation, provide a support area 30%-50% larger than single-beam models. Combined with counterweight design, ground pressure can be reduced to 0.1-0.2 MPa, enabling stable operation on non-hardened surfaces (such as compacted soil). The anti-overturning performance meets the GB/T 3811-2008 heavy-duty standard.
