Australia’s leading mining company, Dauna Mining, recently purchased a Liebherr R9800 backhoe excavator for its BHP Billiton Mitsubishi Joint Venture (BMA) Goonyella coal mining mission in Australia. Over the past 90 years of development, Donovan has successfully provided mining and infrastructure services to a number of well-known mining companies around the world. Daona Mining can meet the needs of various construction and production stages throughout the entire production cycle of coal mines and metal mines. Since 2009, Dana has successively purchased four R9400 and four R9800 mining hydraulic excavators from Liebherr, all of which are used for the mining of coal and iron ore. Liebherr's large mining hydraulic excavator bucket capacity from 7 to 47.5 cubic meters, with 9 different sizes can be selected. The R9800 is the world's largest tonnage mining hydraulic excavator, with a power of 4,000 horsepower and a maximum bucket capacity of 47.5 cubic meters. It can be equipped with a diesel engine as a power source and a motor-driven version at a preferentially priced mine. Liebherr R9800 can be flexibly configured according to the conditions and requirements of different mine users, and is very suitable for the mining of very large mines. It is the perfect partner of Liebherr's 221-ton T264 or 360-ton T284 electric wheel dump truck. (This article comes from Liebherr)
This kind of Commutator Pressing Machine can meet the requirement of different Commutator and armature dimension. It makes the whole pressing process far more iconvinient than by manual. This machine can also be connected to Armature Production Line to meet the mass production requirement.
It can greatly reduce the larbor forces. Firstly, operator needs to load the commutator and the armature core to the required tooling position. Then press the start button. Machine will do the pressing process.
We have two types of commutator inserting machine, the automatic type and the semi-auto type. The automatic commutator pressing machine is equipped with touch screen, all the parameter can be set in the touch screen. It is accurate. This automatic commutator inserting machine can be connected with a mechanical conveyor to acheive the mass production. The semi-auto type one is far more simple than the automatic one, compared with the operation step. And the price is also more favorable.
