The Latest Excavators Of Asia Are Ruling The Construction World

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.

Top 10 Fantastic Types of Excavators

Excavators are heavy equipments used for mining, digging and moving bulky objects. There are different types of Excavators. Here are top 10 fantastic types of Excavators.

Compact Excavator-It is that type of excavator which is basically a wheel vehicle with backfill blade and boom swing that operates independently. It can weight approximately 0.7 to 8.5 tonnes. Its structure has three separate division .The first division is house second one is undercarriage and lastly the workgroup. The hydraulic motors assist in travel functions as well as rotating the vehicle.

Dragline Excavator-Dragline Excavator finds its application in civil engineering and mining of surfaces.

It his divided into two categories

The first categories are cranes which are used for lifting materials. It is heavy in size and is provided with winch drum situated at the front side which acts as a dragline.

The second category is relatively smaller than the first category and is used for civil engineering purposes like constructing roads, bridges, port etc. It is also used for cleaning ponds and canals as well as driving heap rigs.

Wheel Excavator-This type finds application in surface mining. It is very large in size. It has a large round wheel as it name suggests with an arrangement of scoops which help in its rotation. All the materials are carried away from the machine by the discharge boom.

Reclaimer– A Reclaimer is a type of excavator which is used for handling large objects and eliminating heaps of materials. Reclaimers move on a rail between stockpiles. They perform all the instructions with the help of a remote control. All the modern reclaimers functions automatically whereas the older reclaimers are operated manually.

Digger Excavators-Such Excavators are heavy equipments and also has three separate divisions which are house, undercarriage and workgroup. The house comprises of boom and sticks. The second division which is the undercarriage consists of wheels and tracks. It is operated by cables.

Dredging– This vessel is used for cleaning and collecting the sediments and silt deposits in the bottom of the seas or lakes and disposing them to another place. Dredging helps to keep the seas and lakes traversable which would have otherwise become swallow due to presence of silt deposits making the seas and rivers unsuitable for navigation.

Apart from this dredging is also used for making harbours and channels in the sea for accessibility of larger ships. Other uses of dredging include mining of ocean floor, mining of sea beaches that are badly eroded by gales, eradicating garbage and debris, land reclamation etc.

Steam Shovel-The first Steam Shovel was invented by William Otis in the year 1839.

This excavation type is a large machine powered by steam. It finds in application in moving soil and rock. Steam shovel has contributed heavily in public works which dates back to 19th century. This equipment finds its application in constructing rails, roads and canals. They are also used for digging canals, building roads and railways and for mining purposes.

 

Vacuum Excavator-Vacuum Excavator is a vehicle which is used mainly for removing debris on land that is heavy. It is also used for eliminating soil from hole. Its structure consists of a suction nozzle with two knobs which the operator holds with his hands to grip it. For cutting soil and sucking up debris it has a tooth situated at the end of the tube.

Trencher-This type of Excavator is used for mining trenches, deploying drainage. It comes in different sizes and models. There are four different  kinds of trenchers includes Micro Trencher, Portable Trencher, Chain Trencher, Wheel Trencher.

Slurry Wall Excavator– They are used in the construction of concrete walls in those areas which are situated close to ground water table to block the walls enclosing tunnels.
