work condition	consumption	consumption rate
empty load	21.76L/h	158g/kw.h
earth remove	18.53L/h	134.6g/kw.h

Explain:empty load is the condition that,the loader full speed running

on the road,continuly,running for two hours,and get this result.

2.the force of LG855N wheel loader

self weight 17Ton ,adopt 220 horsepower
steyr diesel engine,powerful and low fuel consumption ,

Tracing force means,the force which make the bucket dig into the

material(earth,rock,coal,sand ETC,)also the cut in force.

Breaking out force means,after the bucket dig into the hard material,

such as rock,the bucket need to rise up to pry-out the heavy rock,with

17Tons breaking out force,this loader could be qualified any heavy work.

3. appearance of LG855N wheel loader

this new generation wheel loader adopt American style design,the out fit is fashion,generous and stable

adopt stable frame suport structure for the cab,ROPS/FOPS optionable,over all unit adopt low noise design.

4.inside view of LG855N wheel loader

excellent aero seat,360°adjustable,absorb 90% vibration,make the drive more comfortable

highly sealed cabin,under hard work condition,no dust can get into the cab.sanitation&enjoyable.

adjustable dash board(forward and backward,15°),make operating more comfortable

add cup holder,and the USB socket,which can read external data,also can charge the phone&pad ETC. one emergency power is equiped.optionable high efficient air condition system,defrost system,excellent air circulation function.

adjustable sun-shield

5.the configuration change of LG855N wheel loader

5.1.adopt large displacement booster pump,displacement increase by 30%,the size of brake caliper's oiling Channel,increase by 50%,the major breakthrough of break caliper piston technology obtained the nationaltechnical patent,breaking temperature strictly decrease by 150°C,greatly enhance the reliability of the break SYS,parking break adopt multi-head screw thread Transmission,add auto-return function,which is greatly increase the safety index

5.2.adopt ‘93 dust filter unit ’,which can filter out 93% of the dust just through the first filtration,efficiently improved the reliability of the power system,the problem of burn engine oil decrease down by 90%power assembly adopt frame support system,and dashpot,vibration frequency decrease by 60%,greatly improve the stability of the power SYS,and other related part

5.3 upgrade the Hydraulic system’s oil circuit system,adjust the Hydraulic component's connection method,and welding point,which greatly reduced the fault rate of the Hydraulic SYS,lowered the Hydraulic loss.the Hydraulic component's connection point decreased from 93 to 69,welding point from 77to51,Hydraulic loss reduced by 25%,there upgrade not only decreased the damage rate,but also increased the serve life of Hydraulic work pump and oil cylinder.

5.4 Scientific automatic flat technology, which simplified operation, which greatly reduced the labor intensity, meanwhile, this design can effectively avoid misoperation which cause the scoop cylinder, swing arm, and tie rod Interference and deforming

5.5 reinforced the drive axle,after finite element analysis,

front drive axle compound stress nephogram

wheel edge support,wheel hub and flange bolt section compound stress nephogram

back drive axle compound stress nephogram
after 22years technology accumulation,this new generation LG855N wheel loader,have become the best

production we’ve ever built,it our proud

the number of optimized items,compare with the last generation LG855B wheel loader
