The features of QY25K5:
1, Standard 3-axle truck crane of the most advanced performance
in China with the technology and quality achieved as 30t
class in foreign country.
2, 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.
3, 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.
4, 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.
5, Swing system with free-sliding function can automatic
align to load, offset pinion makes meshing clearance easy
to adjust, less impact and smooth operation.
6, 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.
7, Environmental, energy-saving and powerful engine offers
strong drive for the crane carrier and improves travel performance
for the whole machine.
8, Spacious and beautiful operator's cab, equipped with
adjustable seat, newly-designed air-conditioning system,
etc. all present the concept of "People Coming First".
