QUY650 Crawler Crane is large tonnage and high-end crane product developed by our company to meet need of large crane market and to participate international competition. This machine absorbs domestic and international advanced technology, with advanced design means for optimized structure and outstanding lifting performance. This crane uses crawler as its carrier and combination of lattice type boom, features light ground pressure, travel with a load, high lifting height and heavy lifting load, and tower jib possible for adjacent to high buildings, super-lift system with variable positional counterweight provides strong lifting and flexible maneuverability. The German Hirschman computerized control system ensures safe crane operation. The pump controlled variable displacement hydraulic system works together with electric proportional control system, high efficiency, energy saving and precise control. The power drive parts imported from well-known international companies are environmental and reliable. The super-lift system offers strong lifting performance, and variable positional super-lift counterweight is suitable for various sites and ground. Electronic proportional control and PLC integrated control embody the design concept of people first, and realize crane automatic operation and improve safety, reliability and efficiency for crane operation. The water and dust protections are used to ensure the adaption for the crane in tough working conditions. The hydraulic system of pump-controlled variable displacement combined with electric proportional control system greatly improve the crane performance with energy saving, high efficiency, fine motion control, and smooth and reliable operation. A pressure- measuring adaptor set on the characteristic point of the hydraulic system is easy for state monitoring and fault diagnosis. Well-equipped safety devices and colored large screen display monitor in real-time the engine working and wind speed to ensure crane safe operation. Lattice type boom and jib made of German imported tube features lightweight and high load-bearing capacity. Variable combination of boom sections is suitable for wide range of application. The boom tip single sheave can realize quick lifting for light load in order to improve working efficiency. Swedish Volvo engine and German high-quality hydraulic, electric and drive parts as well as non-twist wire rope, ensure reliable operation and environmental protection. Self-assembly-disassembly of parts heavier than 20 tons, hydraulic assembly-disassembly of boom and turntable, track frame and car-body, mast and turntable, hoist/luffing winch bracket and turntable connection pin shafts. Spacious and comfortable operator's cab with adjustable seats, air conditioner and CD radio set. During operation, operator's cab can be tilted to the rear for wide field of vision. For transport, operator's cab can rotate from side to front as to reduce the vehicle width. The rope reeving, powered pining, German centralized lubrication system, Netherlands status monitoring system decrease labor intensity and embody human nature. |
