Truck Crane-A3 (20t)

Product name: Zoomlion QY20H431 The crane adopts a standard-type and self-made special-purpose chassis with a full-width driver's cab. The chassis drive type is 6× 4. The crane adopts Weifang Diesel Deutzengine which is specially developed for those cranes that often travel at low speed. This kind of engine not only can produce large output torque when it starts and increase the traveling speed quickly, but also has excellent starting performance and good gradeability. The 6-speed gearbox boasts such advantages as large load-bearing capacity, low noise and long service life as well as maneuverable gear-shifting. The crane is fitted with a 32m long hexagon-section boom which is made of high-strength steel, so the boom has strong resistance to bending and torsion. The distinctively-designed circular arc sliding block (having obtained a national patent) makes the stress distributed more evenly, the load carrying capacity stronger, and the adjustment easier. The local rigidity in boom supporting point is good, which has improved the lifting capacity on boom with same thickness and achieved the goal of greater lifting capacity on lighter boom. The safety devices such as load moment limiter, and the complete lighting system equipped in the crane ensure your safety during operation and are convenient for night work.Item Value Remarks Working performance specification Max. rated total lifting capacity kg 20000 Max. load moment of basic boomkN.m 850 Max. load moment with max. main boom lengthkN.m 458.6 Max. lifting height of main boom m 32.60 Deformation of boom is not taken into consideration.
