The XCMG QY70K-II is a 70-ton class full hydraulic truck crane manufactured by XCMG, China's premier construction machinery producer. This model features a five-section main boom extending to 44.5 meters plus a two-section fly jib reaching 15 meters, achieving a maximum lifting height of 59.5 meters. Powered by a Weichai WD615.338 engine delivering 276 kW at 2,200 rpm with Euro3/China3 emission compliance, it operates at a total weight of 43,000 kg with dimensions of 13,930×2,800×3,575 mm.
1.Superior Lifting PerformanceThe five-section oval boom structure delivers exceptional lifting capacity up to 70 tons with outstanding stability. Advanced hydraulic sealing technology ensures reliable operation in high-temperature environments. This proven design optimizes weight distribution for enhanced operational safety across working radii.
2.Robust and Proven PowertrainThe Weichai WD615.338 diesel engine generates 276 kW for consistent power delivery under demanding loads. Its mature technology balances high output with fuel efficiency and operational longevity. The Euro3-compliant powertrain meets regulatory standards while maintaining proven reliability.
3.Excellent Mobility and AccessibilityAt 43 tons total weight and 13.93-meter transport length, it navigates standard roads without special permits. The 6×4 drive configuration and 24-meter turning diameter ensure maneuverability on constrained jobsites. Quick setup capabilities maximize productive working hours between project transits.
4.Cost-Effective OwnershipAs XCMG's mature 70-ton platform, it benefits from extensive parts availability and global service network coverage. Simple mechanical-hydraulic systems reduce maintenance complexity and downtime costs. Strong resale value and proven reliability make it an attractive investment for rental fleets and heavy contractors.
This crane excels in large-scale infrastructure projects including bridge construction, petrochemical facility installation, and wind turbine maintenance where heavy lifting capacity and extended reach are essential. It serves reliably in steel structure erection, port cargo handling, and large industrial plant construction requiring precise 70-ton lifting capability. The QY70K-II is equally capable in highway maintenance, railway construction, and emergency response operations, making it a versatile workhorse for rental companies and specialized contractors across diverse heavy engineering sectors worldwide.
