QY40K |
|
Standard 3-axle truck crane of the most advanced performance in China with the technology and quality achieved as 30t class in foreign country.
First introduced the concept of 25t class with 5 boom sections, main boom length 38.5m and jib length 8.3m, and the lifting height for boom and jib is at the advanced level of international same type of cranes.
Main load-bearing structural parts are made of high strength steel. Application of octagonal boom profile and reasonable setting of half or fully extended boom section contribute the crane powerful load lifting capacity.
Hydraulic system adopts serial items of China State Patent and serial items of technical innovation, so that the whole machine features strong power, energy-saving and high efficiency.
Swing system with free-sliding function can automatic align to load, offset pinion makes meshing clearance easy to adjust, less impact and smooth operation.
Well-equipped with perfect safety devices such as load moment limiter (LML), hoist limit switch, rope-end limiter, safety control valve, hydraulic pressure protection valve, anti-cavitations and anti-blocking device, etc, make operation more reliable.
Environmental, energy-saving and powerful engine offers strong drive for the crane carrier and improves travel performance for the whole machine.
Spacious and beautiful operator’s cab, equipped with adjustable seat, newly-designed air-conditioning system, etc. all present the concept of “People Coming First
