This Hitachi 70-5G was bought in 2014 after I had just finished the year in 2014. It was 478 thousand, more than 250 thousand, and about 500000. Now it has been used for 7000 hours. This machine has been working all the time. Because our county (Sichuan Mount Emei) is a few 80% of the excavators are Hitachi, and our site. Only Hitachi is recognized, and after sale is more perfect, so I didn't think much about it and chose Hitachi.
First say the merits, this machine is 0.33 of original bucket, and then changed into the old Hitachi 0.28 of the bucket, the main work in our home work, so the fight is still cost-effective. The fuel consumption is very provincial, basically an hour at about 30 yuan, stronger than the Komatsu. The operation speed is very fast, strength belongs to the middle and upper level of this level. Never exploded. The tube has only been replaced by two original gear and lost track once.
Here is the shortcoming, first of all, the engine has a bit of oil burning, we all have this situation here, but it is not serious, it does not take the black smoke and blue smoke, and does not delay. It is every maintenance time to add some oil, I have 500 hours maintenance. When the cold is in the outside, the oil seal occasionally has a little oil leakage, But it is not serious. Also, the gap between the root of the big arm is a bit large, and it may be related to the often dry hoisting. After that, the repair master has been repaired and there is no problem.
Through the use of these years, I have proved that I did not have the wrong choice, this machine has been very difficult to use, and has never been able to work hard. Although there are some small shortcomings, it has not been affected. It has been the original maintenance of the original factory. Every time the price is seven hundred or eight hundred yuan, the price is higher, but the province is a province. Heart. I always think that digging is like a human being. If you treat it well, it will give you back.
