ZOOMLION QY90V truck crane, which is developed independently to adapt to the market demand, is our new-generated and high-reliable product combining our company many years’ manufacturing experience with advanced technologies. Its lifting height, boom length, working speed and lifting capacity have all achieved advanced international level.
This truck crane, with spacious cab and luxurious equipments, adopts full slewing systems, telescopic boom, electro-hydraulic proportional control system and self-made full-width special purpose chassis with 5 axles. The switches, control levers, control lights and controls, which are all designed on the basis of ergonomic theory, provide driver and passenger with comfortable and convenient operations. 10×6 drive and hydraulic power steering mechanism provides the crane with good driving performance and flexible steering. Exhaust emission is in conformity with the EURO III and its safety devices are accordance with CCC (China Compulsory Certification).
The latest electro-hydraulic operated directional control valve and 3 series-connected pumps are all of load-feedback function which ensures the actuating mechanism to fulfill its working performance to the utmost. The control type of two levers, which are flexible and stepless speed regulated, can carry out any of the 2 crane movements “Spool up main / auxiliary winch”, “Reel off main / auxiliary winch”, “Telescope boom in / out”, “Derrick”, and “Slew” simultaneously. All that not only provides the crane with stable and reliable simultaneous movements but also greatly improves crane’s working efficiency. The safety devices fitted in hydraulic system, such as relief valve, balance valve, hydraulic lock and brake valve etc., prevents the oil line from overloading and the accidents caused by oil pipe breakage.
The safety devices, such as load moment limiter, and lighting systems equipped in the crane ensure your safety during operation and are convenient for night work.
This crane has a novel style which makes it beauty in form, beauty in figure, and beauty in color.
