QAY800 new terrain crane integrates 222 patent techniques, adopts 38 new patents techniques, and shows 8 technical highlights.
1)The overall length in travel is only 15.77m, the weight is 60t, the chassis length is 13.77m, and the minimum turning radius is 10m. The whole configuration includes 6-segment boom with the length of 62m and 3segment jib with the length of 28m. 6 counterweight combinations can finish nearly 30000 working conditions.
2)Adopt the imported Benz EFI engine with strong power system and imported 12gear automatic control transmission. The 2nd, 4th, and 5th axles are the drive axle. The steering form is 10x10 full-axle steering.
3)Adopt new single cylinder retractable technique and high-intensity imported steel, featuring lighter dead-weight and stronger performance.
4)The selfcombination counterweight technique developed by ourselves can effectively improve the lifting performance by 30%.
5)The electrohydraulic proportion control multiaxle steering mode can realize many kinds of steering modes.
6)The new brake technique can reduce 2/3 maintenance cost, and improve the travel safety.
7)The comfortable cabs and outrigger operation completely show the humanity design concept.
8)Equip with the XCMJ unique control system, auxiliary retractable boom system, virtual wall system, perfect failure diagnosis, real-time detection, CAN technique, etc.
