ZWY-80/22.55LColliery Backhoe Loader(ballast raking equipment),it is mainly used in construction of railway tunnel, road tunnel, diversion project, mine roadway, phosphate rock, coal, and so on metal non-metallic mineral ore mining loading.Applicable to the section of 2.2 x 2.4 meters of large and medium-sized roadway,Big power, fast loading; Simple and compact structure,Humanized design, easy to maintenanceThe whole body adopts carbon dioxide protection welding,Hydraulic and electric elements adopt famous quality products, reliable performance。
Main feature:
1.It shovel therocksby bucketand trasport bybelt conveyor, The belt conveyor deliver to the truck;
2.Itisuse of electric hydraulic transmission,hydraulic walking,mining acquisition,deliver,truck loading,Compact bodies, propulsive force is big, wide scope of pick,
3.It is controlled by pilot valve,easy operation,reliable performance, easy maintenance,Humanization design.
The environment conditions:
a)Thediameter of roadway section is above 2.4×2.4M;
b)The platts hardness of rock(f)<12,lumpiness<400mm，porosity<1.8t/m3;
c)Altitude≤1000m;
d)Temperature of roadway-5℃～+40℃，maximum relative humidity≤90%(temperature=25℃);
e)Voltage deviation±5%,Frequency limit deviation±1%;
f)Roadway slope≤10°;
g)Loader when working around the coal dust, methane, explosive gas content security content should comply with the regulations of coal mine safety regulations.
