70tons hydraulic mobile truck crane QY70KC

Five-section 48m main boom, single-plate boom head, compact boom tail, lifting performance leading the industry with 9% of new products of the same tonnage, medium-length boom, full boom
The performance under high-frequency conditions is 10-15% ahead.
Off-road type four-axle dedicated G-type chassis, equipped with low-speed high-torque power transmission system, taking into account low-speed climbing performance and high-speed transition
Performance, the maximum climbing ability is 41%, the maximum driving speed is 90km/h, it can carry full counterweight for short-distance transitions, and it is highly maneuverable.
G-generation dual-variable pump + post-valve compensation load-sensing system, dual-pumps are automatically divided and combined for control, which can achieve compounding of any working conditions, and the operating efficiency is industry-leading. The use of post-valve compensation technology reduces the throttling loss of the hydraulic system and improves lifting operations
Micro-movement and smooth operation realize the perfect combination of cost-effectiveness and precise control.
The reliability of the electrical system is fully improved: waterproof and dustproof connectors, wire harness branch metal splitter protection, high temperature resistance 150 ºC closed bellows, protection level reaches IP67.
