After the manufacturing of the latest excavators in Asia and its landing in the global market, a friendly business deal has smacked between CNH industrial and Sumitomo Construction Machinery.

Korea was the first country to evolve Hyundai R430LC-9A, which is a European unit. It was an excavator of class crawler type whose weight is 43 tonnes. It perfectly bridged the wide gap in the gamut of Hyundai beginning from 38 tonne R380LC-9A to 48 tonne R480LC-9A.

A critical study on Asian Excavators

Finland was the country which purchased the first unit of excavator from Soumen Telakone and is now able to dig out the heavy rocks with ease, as the getaway force of the equipment is 20,411 kg. The Cummins QSL9-Tier4 Interim/Stage IIIB engine of R430LC-9A provides a measured power of 231kw to give out. To increase the speed of the engines, the power utilizes the fuel in Xtra-High Pressure Injection system to carry out a continuous gush of condensed fuel across every engine. The operator can pick up any of the three available working modes-S for Standard, P for Power and E for Economy. This selection of working mode is invariably dependent on the type of job to be accomplished. It is known as Computer Aided Power Optimization and this system was present in the previous models of 9A series.

The three recent models of excavators of the E-series of Liu Gong attract the attention of every heavy equipment user. The updated models of the excavators 922LC and 925LC are 922E and 925E respectively. Among these models, 930 is the brand new one which has just knocked the doors of the construction industries.

The functional weight of 922E excavator is approx.22 tonnes with a digging capability of 6595mm. The weight of 925E is 25.5 tonnes and can make an underground passage of 6925mm. The excavator 630E weighs 31.3 tonnes whose highest depth of digging is 7300mm.

Construction experts prefer 922E to 922LC because the former has 8% more fuel efficiency and can dig grounds at least 5% better than the later one. Liu Gong has designed these machines with six working modes namely Fine, Power, Lifting, Breaker, Attachment and Economy. These excavators also contain automatic fluctuation of two-way velocity which enables the operators to switch to fast mode in normal ground conditions and slow mode when the equipment is working on rocky surface.

The new excavators are installed with Yanmar engines along with integrated Flow Pump System. This integrated pump system makes use of the technology of triple-oil pump for constant travel, enhancing the performance of digging and loading. Apart from these, the other exciting characteristics are the inclusion of a perfectly designed dozer blade to minimize the over-spill while levelling and a sound balanced operation for digging along the wall boundaries and trenches.

No doubt, these excavators of latest design from the Asian countries are ruling the construction field making the work smoother and easier. But while choosing the excavator of your need demands for a complete understanding of all the job requirements which you are planning to carry on with these modern excavators.
