Product Description

The XCMG QUY70 crawler crane is developed based on XCMG’s extensive experience in crane manufacturing, specifically designed to meet modern market demands for a medium-duty crawler crane. With a maximum rated lifting capacity of 70 tonnes and a maximum lifting moment of 344 tonne-metres, the QUY70 is engineered for optimal performance in demanding lifting environments. Its main boom spans from 13 to 58 meters and is complemented by a fixed jib that extends from 9 to 18 meters, mounted at offset angles of 10° or 30° to accommodate various lifting scenarios.

The crane is powered by a 200 kW diesel engine and offers a maximum hoisting speed of 120 m/min and a luffing mechanism speed of 57 m/min on the first layer, allowing for efficient operation. It travels at speeds up to 1.2 km/h and can climb grades up to 30%, making it highly mobile on rough job sites. The slewing system has a rotation speed of up to 2.4 rpm, ensuring smooth positioning of heavy loads. The average ground bearing pressure is 0.087 MPa, enabling stable ground contact.

With a transport weight of 64 tonnes (including the 13-meter boom and main hook) and a maximum transport component weight of 39 tonnes, the QUY70 is engineered for efficient dismantling and transport. Its compact transport dimensions (12.6 × 3.32 × 3.23 meters) allow it to be shipped with ease. The crane also comes equipped with extensive safety features including overload limiters, boom angle indicators, and hydraulic cutoffs for safe operation under various load conditions.

Built with a robust lattice structure and utilizing advanced materials and hydraulic systems, the XCMG QUY70 is ideal for medium-heavy lifting work in construction sites, especially in remote or rugged terrains where mobile cranes are less effective.
