▌“Shan Tui Tui Installed Machine Bar Bar，It has low fuel consumption.，And efficient，Maintenance is also convenient，It's hard not to love.！”When referring to the application experience of Shantui's first side-discharge version pushing machine，Manager Zhang, the equipment management manager of a plateau tunnel project, raised his thumb.。

▌Manager Zhang's company is responsible for the plateau tunnel project, which is located at an altitude of more than 3300 meters.，In the plateau working condition and the tunnel working conditionBUFFSuperimposed，Many brands of scraper equipment are deterred.。After doing a lot of research, Manager Zhang and his team chose a pushing machine of mountain pushing and side unloading version.，Customized configuration is made in many details.。

▌“The tunnel is about 20 kilometers long.，We are responsible for six kilometers.，The environment in the tunnel is relatively harsh.，And the rock is hard.，It is difficult to pile up and transport slag.，We also did market research in the early stage.，Finally, I chose this side unloading version of the pusher machine.，It is indeed much better than the wheel loader.，Save fuel、High efficiency、The stability is strong，It was the right choice.。”

▌Manager Zhang spoke bluntly，Construction of plateau tunnel，The test of high pressure and low oxygen environment to the equipment is extraordinary.，Especially in the aspects of power system and hydraulic system.。Shan TuiDL300-GWeichai is used as the pusher. WP10HFour-stage emission engine，It can still maintain strong power under high pressure and low oxygen environment；Gold core combination with Linde hydrostatic system，Transient response achievable，Higher transmission efficiency，Compound action can be done.“Hand to heart”。

▌The driver, Fu Shifu, has been driving the equipment from Shantui to the installation site.，How do you feel about using this pushing machine?，He also gave a high appraisal.：“This machine can turn in place.，It is very flexible to construct in the tunnel.，Another is that it is very strong.，It's no trouble to shovel the bottom.，It's easy to fill the bucket.，The consistency of the operation is very good.，Push、Shovel、Install、Unloading rhythm is very fast.，Very efficient。”

▌Fu Shifu said，In addition to overcoming high pressure and low oxygen, tunnel construction，Water accumulation and skidding、Problems such as excessive gravel can also be seen at any time.，And he and Manager Zhang agreed with this mountain pushing machine.，But also in its several transcendent manifestation.。

▌“On several occasions, the stones broken by the gunners were relatively large.，Wheel loader end not moving，The pushing machine can be moved.，Counterweight is also OK.，No ass，Directly in one step，Here, put it on the side.；Besides, it's caterpillar.，Slag padding is basically not required.，If there is a stone or something, just press it directly.；There is also a better view.，You can see left, right, front and back.，I have to say, very mature in every way.、It's in place。”

▌If we say that fuel saving and high efficiency are the key to the construction of plateau tunnels.，That reliability and simplicity is the most important thing to ensure normal construction.。According to Manager Zhang.，Shantui Push Machine works about 8 hours a day without interruption.，Although the strength is not high.，But the tunnel construction is closely linked.，Equipment stability、The convenience of maintenance and the timeliness of after-sales service are related to the progress of the whole project.，So it can't be ignored。

▌Shan TuiDL300-GThe structural parts of the pushing machine are strengthened.，The key components are subject to rigorous experimental testing.，At the same time, the Shantui four-wheel belt is famous for its reliability and durability.；Daily maintenance parts are all within reach，Maintenance channels have also been optimized.。

▌For these，Fu Shifu, who deals with Shantui Pushing Machine all day long, has a deep understanding.：“Things like waterproofing are in place.，In addition, the security protection is also very good.，Work with a sense of security.；And beating butter、It is very convenient to change the air filter for daily maintenance.，Basically, it will be finished soon after work.，It won't take long.。Can you think of the details?，Shantui thought of it.。”

▌The after-sales service that can not be ignored has also been affirmed by Manager Zhang.，He said：“In the early stage, Shantui technicians were stationed to ensure the normal operation of the equipment.，Later, the after-sales service personnel of Sichuan Shantui were also on call.，Professionalism and timeliness were spot on.，With the mountain push and push machine，It makes the whole project a lot easier.。”

▌Distance tests a horse's strength.，Shantui's first side-unloading pusher and the plateau tunnel project have gone through trials and hardships all the way.，Demonstrated fuel economy、Efficient、Reliable、Simple characteristics，Won the unanimous praise of the project team.。In the future, Shantui will continue to join hands with the project team to overcome difficulties.，Meet a mountain and open a mountain，Bridge in water。
