Introduce:
QY25K Truck Crane outline profile and hydraulic system won 6 China state patents.
4-section boom of all-round octagonal boom profile, single cylinder for front support elevation, low center of gravity, good stability.
Main and auxiliary winches are independent each other, work not only individually but also simultaneously.
Full-width driver's cab with wide vision is convenient for operation.
Swing system with free-sliding function automatically align to load. Pinion offset makes meshing clearance easy to adjust.
New materials are used to minimize the vehicle total weight and maximize the whole vehicle performances. Main performances are in the leading position in the industry.
Hydraulic pilot control system realizes all operations precisely with softly pushing the two joysticks on armrest (mechanical operation system for option).
Hydraulic valve block is integrated modular designed, little pressure loss and high work efficiency.
Counterbalance valve designed with international technology, oil filter, anti-cavitations device and plug in hydraulic circuit make operation more reliable.
Well-equipped safety devices such as automatic load moment limiter, hoist limit switch, and wire rope over-release cut-out device make operation more safe.
Engine, air conditioner for superstructure and carrier and hydraulic device are available for option.
