Products Description

70 ton truck crane China new hydraulic mobile crane QY70KH/QY70KC-I/QY70KC for heavy lifting work

QY70KH Truck crane is widely used for the lifting operations in general engineering projects, such as construction site, urbanrenewal, communication and transportation, ports, bridge, oilfields and mine, and complex working environments.

* 48 m super boom, stronger performance in high-frequent use working conditions
Five-section boom of 48 m has the lifting performance of 8% over the cranes in its class and 10-15% higher when the boom is partially and fully extended and used frequently.

* Optimal power transmission system
Off-road specialized four-axle G-class chassis with low speed large torque power transmission system equipped, features higher climbing capacity at lower speeds and job site transfer capacity at higher speeds, i.e. maximum grade ability 41% and a maximum travel speed of 90 km/h.

* Exclusive control technology of simultaneous movements, more efficient
G1 generation double-variable pump along with after-valve compensation load-sensitive system contributes to fine control of lifting operation, smooth operation and industry-leading working efficiency, leading to economical, efficient and precise control.

* High grade electrical protection, more reliable operationImproved electrical system reliability: waterproof and dustproof
inserts, high temperature-resistant corrugated pipes, special wire harness closure sleeves and rubber sleeves are used, excellent dust protection, protection level up to IP67.
