QY25K Truck Crane
◆Engine, air conditioner for superstructure and carrier and hydraulic device are available for option.
◆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.
◆QY25K Truck Crane outline profile and hydraulic system won 6 China state patents.
◆Counterbalance valve designed with international technology, oil filter, anti-cavitations device and plug in hydraulic circuit make operation more reliable.
◆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.
◆4-section boom of all-round octagonal boom profile, single cylinder for front support elevation, low center of gravity, good stability.
◆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.
◆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.
