The crane design is based on the absorption of foreign advanced technology, aims at the world advanced level and emphasizes on both reliability and exterior. Power, drive and hydraulic components as well as steel plate and wire ropes are selected from domestic and international famous enterprises. QUY300 is gifted lots of advantages such as less ground pressure, smaller turning radius, lifting without outriggers, pick and carry load, long boom length, larger working radius, powerful lifting capacity and good fine motion control etc. It can work with 360°full swing and accommodate rough road. Pilot proportional control, pump-controlled variable displacement, high precise control. This crane has additional function of automatic assembly and disassembly, light weight for transport, easy for work-site transfer. QUY300 can be equipped with kinds of booms such as heavy-duty boom, base boom, light-duty boom and tower attachment, which can meet different requirements of customers, tower attachment in particular enable the crane to work closer to buildings.
