LW700KN is the most popular model of China 7t loader, now LW700KN is upgrading to new model equipped with EURO III engine with electric injector, new model will have high performance. 

High Firmness and Reliability:

The high quality diesel engine elaborately designed and manufactured especially for working conditions of construction machinery and sufficiently proved by the market is fitted with desert air filter to prolong the service life of filter element, improve the filtration accuracy,and reduce the wear of engine.

The heavy-duty design, thick plate structure, and robot welding ensure secure welds, high torsion resistance coefficient, and strong overload capacity and can endure the torsion and impact loads under all kinds of working conditions.

The rock bucket is made of high strength wear-resistant plates, with the reliability leading the industry. Drive parts of outstanding performances.

Two groups of double-row tapered roller bearings are adopted for the main hinge joints, featuring high carrying capacity and long service life.

The finite element analysis technology is adopted to reduce the stress concentrationand eliminate the partial weaknesses so that the frame is resistant against impact and overload and handles with ease all kinds of overload conditions.

The innovated lubricating mode for sh aft sleeves and hinges an d the oil groove lubricated shaft sleeves effectively improve the reliability and service life of hinges.

The bucket is completely made of high strength steel plates and the en-handed holder and sleeve type bucket teeth are adopted to improve the wear and impact resistance by more than 30%. The automatic robot welding is adopted to guarantee the quality and prolong the service life for each weld.

The high quality electro-hydraulically controlled parallel-shaft power shift transmission is adopted, with automatic gear shift switch (KD function) and four forward and three reverse gears. featuring advanced performances and high carrying capacity, it can completely meet the required power demand of the loader. The drive axle adopts heavy-duty wet type drive axle to realize higher reliability.

The front drive axle adopts three-section heavy-duty drive shaft to greatly improve the carrying capacity. In the enhanced construction machinery drive shaft structure, the drive shaft flanges are of DIN and SAE standard specifications, the bolt circle diameter of the fastening bolts is increased, and the high strength bolts are used for secure connection and reliable drive.
