China Heavy Hoisting Machine 650ton Crawler Crane Quy650

QUY650 crawler crane maturely applies key techniques, such as superlift control, twin-winch synchronous control, boom backstop control and double-hitch boom rising technique with powerful lifting performance. Super long main boom and jib and many combinations of working condition satisfy customer's requirements in the full extend. Counterweight combinations are suitable for various working sites. Various combinations of standard and superlift counterweights and adjustable swing radius are suitable for different kinds of working sites. Pump controlled variable hydraulic system combined with electric-proportional operation and German program control system make the whole operation and control system energy saving and high effective with precise control and safe operation. Power drive elements of world famous brand are environmental and reliable. Comfortable operating environment, self-orientating device, reeving technique and German centralized lubrication system reduce the working intensity and embody ergonomics of design.
