On the basis of LW520F wheel loader, LW521F wheel loader gets improved in terms of hydraulic system, working mechanism, frame assembly and cab, by which greatly improving the machine performance in the aspects of machine technial data, reliability, operation comfort, working efficiency, machine maintenance and out-looking shape.
Rational and optimized designing of the machine frame improve the stability of the machine.

The hydraulic system is of integrated dual-pump system, which is featured in fuel-saving and high efficiency, and while reducing the total working cycling time, by which improving the working efficiency.
The gear-shfiting control adopts flexible controlling mechanism, which features in high reliability and easy operation. The Reverse warning device makes it more safe and stable during working.
The more rational axle load distributioin makes the machine has more competative advantage in term of traction.
The critical articulated joint adopts anti-dust enclosed lubrication, so the pin shaft and pin sleeve have longer service life.
The out-looking shape is of streamline designing, with XCMG features.
The canopy-top cab, adopting " Korean Green" glass, is of unique out-looking shape and harmonious color matching.
The injection-moulded instrument panel is very nice in out-looking. The cab is standardly equipped with heater.
The hood is of non-metal material, which features in noise-absorbing and easy maintenance.
The 3.0 m3 bucket is equipped on standard machines, fitted with cutting edge, which improves the machine reliability and endurability.
The power unit used on the machine is of WeiFang engine: WD61567G3-28.
