The previous public number of tweets have been introduced, since 2013 and 2014 Liebherr 2 r9250/250 ton, 1 sets of r9350/300 tons of electric hydraulic shovel, such as large tonnage mining equipment successively stationed in China's well-known mining companies-Yunnan Hualian Zinc Indium Co., Ltd. Open Mining mining area,
With the help of large-scale mechanical exploitation, the whole mining area is being upgraded in all directions.
"Liebherr large-scale mining equipment, to create more value for customers" 5 years, as the mining and stripping operations of the main equipment, the 3 large electric hydraulic shovel has been operating for more than 20,000 hours overall.
They not only greatly simplified the large mechanization of the mining costs (mining machine from 300 to 80 units, mining workers from 600 to 200), but also increased daily stripping to 5000 cubic meters, so that the mining area to maximize the release of productivity. In addition to these actual value increases, can Liebherr-electric hydraulic shovels bring significant additional value?
Let's take a dip today.
Considerable value:
Electric drive: Bring more than ' 10 million + ' every year
The cost savings, there are green mines Mining costs, is the world's largest mining in the most important, in the advanced management concept of Hualian zinc-indium mining area is the same.
Over the past 5 years, the mining chiefs have been paying close attention to the operation data of Liebherr's 3 large electric hydraulic shovel, and have accurately accounted for the unit cost of the production.
According to the introduction, after the use of electric driven hydraulic shovel, each shovel to install a cubic scrap of the electricity cost of about 0.4 yuan, and the same situation of diesel-driven equipment, energy costs of about 1.5 yuan, it is obvious, through the use of electric-driven hydraulic shovel, Hualian zinc and indium per square scrap can save 1 yuan of stripping costs.

' Hualian Zinc indium General Manager Assistant Zhang Chenggung said. Electric hydraulic shovel, different from the traditional excavator, its motor does not need to frequently like diesel engine as regular maintenance, compared to traditional hydraulic excavators, ' and save a lot of cost '.
Pan Wenkun, assistant director of the mining workshop of the zinc-indium mining area, Hualian added.
"Trouble less","Not love bad","power cost is low","cost benefit is significant", etc., is the lead and operator in the zinc and indium mining area of Hualian in 5 years of actual use of the process, to these 3 units Liebherr large-scale equipment most straightforward, most profound impression. In addition, in the national environmental requirements increasingly stringent background, ' electric-driven mining equipment is helping to push the Hualian zinc and indium construction and build green mine.
' said Zhang Chenggung.
Considerable value:
To teach a man to fish,
Cultivating professional Technical maintenance team for mining area
According to Liebherr Haier technical service personnel, in China's large mines delivered 9 of electric hydraulic shovel, the three equipment operating efficiency has been at the forefront.
After acquiring the modern mining equipment of Liebherr, ' we began to think about how to release the advantages and benefits of these devices ', said director Li Zhen, in management, Hualian Zinc and indium has strengthened the management of standardized personnel operations, especially the management and training of drivers and maintenance technicians.
Liebherr Electric Hydraulic Shovel R9350 These three electric hydraulic shovel drivers are trained by the Liebherr manufacturers, is the mining area with the highest operating skills of a group of key staff.
Equipment Management department will also be based on the driver of the machine control, day-to-day maintenance of equipment, as well as standardized operations, such as the overall performance of a regular all-round assessment, the establishment of rewards and punishments incentive mechanism to mobilize staff enthusiasm, at the same time for the enterprise training, selection operation and maintenance reserve forces.
In the technical support, around the three electric hydraulic shovel, Hualian zinc indium set up by 12 employees of professional and technical maintenance team.
