On the basis of LW420F Wheel Loader, LW421F Wheel Loader gets improved in terms of hydraulic system, working mechanism and out-looking shaping, by which greatly improving the machine performance in the aspects of machine technial data, reliability, operation comfort, working efficiency and machine maintenance.
Main technial features of LW421F Wheel Loader:
　　·The articulated joints adopt anti-dust closed lubrication. And pin shaft and shaft sleeve have long service life.
　　·The bucket is uniquely designed, with little cutting-in resistance, large factor for full loading, strengthening bucket teeth and edge teeth, which makes the bucket more reliable and endurable.
　　·Adopting the integrated-flow system for the hyaulic designing, which are of energy-saving and high efficicy, so reliability of the system is greatly improved. The hoses, fittings and sealing parts are all internationally purchased.
　　·The more rational axle load distibution improves the traction performance of the machine.
　　·The instrument panel is of injection moulding plasic, which has a nice looking.
　　·Integal engine hood made of glass fiber lessens vibration and noise.And there is a lock on the side door, which is activated pneumatically, so it is much safer and reliable and also being easier to make maintenance for the diesel engine.
　　·Uniquely-designed operation cab, with "Korean Green" glass, nice-looking appearance, overhead canopy and harmonious color matching.
　　·The machine is controlled through flexible shaft, with gearshifting operation, reliable performance and easy operation.
　　·The front and rear frame are both uniquely designed, with more rational structure and endurable performance.
　　·The machine is equipped with Reverse warning device, which makes it safer during working.
　　·The headlights and working lights are of "Xiaosong" lights which are uniquely designed with high quality.
　　·Be optional with various kinds of working device, and the bucket is also optioanl in term of bucket capacity, which can make it match with different working condition.
　　·The out-looking shape and painting are of the uniform of XCMG Wheel Loaders, which highlights the XCMG brand.
