300 Ton Crane Truck

 

The third generation hybrid frame structure is fully applied, the frame cross-sectional area is increased by 9%, the frame load-bearing capacity is increased by 15%, and the deformation is increased by 25%. . 220T-class super-large cross-section main arm, response surface technology simulation optimization analysis, full-extended arm deflection is 10%, and high-frequency performance is 8%.

 

 

Newly upgraded intelligent flow control system and dual pump independent oil supply, precise, high-speed and smooth control, more accurate lifting assistance. . Self-adaptive technology for slewing conditions, real-time adjustment of slewing torque according to the vehicle load weight, no shaking and small impact when slewing, more stable lifting assistance.

The counterweight structure is re-optimized, and the auxiliary counterweight self-disassembly and assembly technology is applied, saying goodbye to the "small schoolbag", and the counterweight disassembly and assembly does not require auxiliary lifting. Heavy-duty transfer technology, wear-resistant tires + high-strength axles + multi-axis balanced suspension, load-carrying driving capacity ↗ 13%.

 

 

One-touch telescopic arm function with working condition recommendation + automatic telescopic, which can quickly telescope the arm according to the optimal working condition and facilitate lifting. . The slewing, telescopic, luffing and winch control actions can realize parameter custom configuration, and provide 3 gear responses to meet the operating requirements of different working conditions, making the operation more handy.
