admin — Wed, 07 Apr 2010 01:52:36 +0000

Volvo will launch four new machines in its compact excavator range in the shape of the EC15C, EC17C, EC18C and EC20C, replacing the existing EC15B in XR, XT and XTV variants and the EC20B in XT and XTV variants. The new machines cover the 1.5 to 2.0 tonne weight classes.

New features include hydraulic hoses routed inside the boom while a new hydraulic translation function gives the operator the choice of using either hand levers or foot pedals so that his hands can concentrate on the pilot controls.

Another important function is the simultaneous control of slew and offset movements using the electro-proportional roller. Volvo says this feature is crucial for faster, more precise performance as well as operator comfort, as are the C-Series excavators’ new more spacious Volvo Care Cabs and sleek canopies. Routine daily operator maintenance checks are quick and easy with these new machines, as all service points are readily accessible under the engine cover.

All four models are powered by a 12.3 kW diesel engine.

In April 2009 Digger Exports in China Continued to Slump

admin — Sat, 14 Nov 2009 04:17:59 +0000

The foreign market is depressed. In April 2009, China exported 118 excavators, they accounted for only 1. 1% of turnover, up 77. 99% of annual average, which has continued to expand in the reduction rate. In March 2009, the export volume of 142 Chinese miners were reduced to 75. 13% over the same period last year. Of America and Japan, the two largest markets for construction machinery, in late March 2009, employees of the construction industry have been killed by 147,300 in the United States, representing 2. 3%. Currently, the number of jobs is about 6. 38 million, up 13. The 2% during the same period last year. In Japan, sales of the three largest construction machinery manufacturers have been rejected by 15% (to end March 31, 2009), 46. 4% reduction in operating profit and average gross profits declined from 13. 5% to 8. 5%. Moreover, it is expected that the benefits of all income and the operation will be reduced to 21. 6% and 50% respectively, the average gross profit on sales of cutting 4. 4%. Excavators are the variety most commonly sold in the earthmoving equipment, sales of loaders and bulldozers are poor. According to statistics, in April 2009, the growth rate of sales from search engines had already recovered the scope defined and it is possible that sales of loaders and bulldozers will be even lower than expected. The market share of domestic brands in the form of Chinese industry increase sales of corporate giants in the market are better than average. In the first quarter of 2009, the market share of domestic brands is about 26%, a slight increase compared to 22% in 2008. Among national brands, the market shares of the giants and the rapidly increasing market share of regional averages partial and small brands have experienced a downward trend, SANY, and Yuchai LIUGONG make quarterly increases from year to year SANY was increased by 120% yoy. Sales of Hunan Sunward Intelligence Machinery Co., Ltd. retreated ia export allocation. XGMA sales Xiamen Machinery Co., Ltd. has grown rapidly, but still had some disagreement with projected sales for 1400. In April 2009, has sold 302 hunters LIUGONG, essentially taking the line compared to 303 in the same period last year and better than average. SANY has sold 635 machines to dig with the growth rate of 69. 33 years% yoy, but the growth rate has also experienced downward trend month by month. Among the manufacturers of blades of foreign capital, only Chengdu Kobelco Construction Machinery (Group) Co., Ltd., and Volvo has exceeded the average growth rate, Doosan, Caterpillar, Komatsu and Hitachi were below the rate of accumulation of reduced sales 10% a year. But since the growth rate of aggregate sales -24. 34%, it was always clear to domestic manufacturers to replace imported products. Sales growth in China’s industry is mainly Digger drove by the real demands of reconstruction after the earthquake, construction of rural roads in farm buildings to conserve water, road construction and mining, etc., also benefited from the 4 billion yuan investment plans. Currently, Chinese Digger industry is not very promising, even partial companies reduce the terms and conditions by adopting comparative preferential payment terms to complete the sale of tasks. However, construction projects, there are not enough, resulting in the growing phenomenon of the return or refund the purchase exceeds the time limit. That these risks will become the industrial crisis, real or not will be determined by the macro-economic trends in the second half of 2009 in China.

Excavator refers to the earth-moving machinery, digging material from where is higher or lower than bearing surface by the bucket, then deliver into a transport vehicle or unloaded upon the material pile. The material excavated is soil, coal, sand, and the pre-loose soil and rocks. In recent years, from the perspective of the development of construction machinery, excavators developed relatively faster, as one of the most important construction machinery, it is crucial to choose the excavator with the proper model.

It has been 130 years history since the advent of the first hand excavator, during which they experienced the development process from the steam-driven rotary excavator bucket to the power-driven and internal combustion engine-driven rotary excavator, then automatic hydraulic excavator with application integration technology step by step.

Due to the application of the hydraulic technology, in the 40s of 20th century, there was the tractor equipped with a suspended hydraulic backhoe excavator, in the early and mid 50s of the 20th century, have developed a full-drag type rotary hydraulic excavators and crawler-type full – hydraulic excavators. The initial trial production of hydraulic excavators adopt the hydraulic technology of aircraft and machine tools, due to the lack of hydraulic components which is suitable for various working conditions, the manufacturing quality of excavators is not stable enough, and the supporting parts are not complete. From the 60s of 20th century, the hydraulic excavator enters into the stage the promotion and vigorous development, and the varieties of the excavators, also the excavators manufacturers increase dramatically. During the years of 1968-1970, hydraulic excavator production accounts for 83% of the total output, currently is close to 100%.

What’s new in the mini excavator field?

admin — Sat, 14 Nov 2009 03:28:27 +0000

manufacturers are concentrating their efforts on developing new machines and technologies in readiness for when business of mini excavator picks up. A range of mini excavators were unveiled at the Intermat Exhibition held in Paris earlier this year, including JCB’s new 6.5 tonne 8065 RTS tracked mini excavator. This reduced tail swing model replaces the 8060, and features a Stage IIIA(Tier 3), 40.5kw Isuzu engine. It has a maximum dig depth of 4.35 m and a 4.27 m dump height.

According to Christophe Lecarpentier, product manager for the compact and heavy line at JCB France, “The dozer blade allows the materials to roll around when pushing the earth providing a better flow of material which helps improve productivity”. The technique also prevents the blade from becoming blocked by the earth when moving forwards.”

He added operator comfort is also very important and the door width provides easy access to the machine’s cab. The operator’s controls move with the suspension seat that, he said, is quite unusual on a compact machine. “but customers were asking for this as they were used to it in bigger machines.” he explained.

He went on to say that even with reduced space in the new machine there is good accessibility to the components for service and maintenance.

Amman Yanmar meanwhile has developed the SV20, a new 2 tonne class mini excavator, which is a mix between the SV range of machines launched at the previous Intermat in 2006 and the compact Vio 20 unit, The undercarriage, boom and arm are similar to the Vio 20 and the upper structure and cabin are from the SV series machines. Featuring a 290 mm lateral overhang and 50mm rear overhang the “semi-Vio” model is not a zero tailswing machine. It is lighter than the Vio 20 but with similar digging forces and uses the same Yanmar engine. A 2.19 tonne cab version and a 2.05 tonne canopy model are available.

New to the range at Doosan subsidiary Bobcat is the 5.5 tonne class E55w wheeled excavator. This machine is made for Bobcat by its parent company in Korea, and is available from Doosan as the DX55w. However, it is new to the Bobcat range-in fact it is Bobcat’s first ever wheeled excavator.

Also new to the Bobcat range is the new generation of three and a half tonne excavators including the conventional tailswing 3.2 tonne E32 and the zero tailswing 3.5 tonne E35.

Also new from the company this year is the 6 tonne zero tailswing E60 crawler excavator, powered by a 38 kw Yanmar disel engine.

Finally, Bobcat has just introduced two smaller models in the 1 to 2 tonne class, the E14 and E16. Powered by the 3-cylinder 9.9kw Kubota D722 engine, according to the company they are both designed to be easy to transport and offer smooth, powerful performance and increased reliability and durability.

The E14 has a standard operating weight of 1,303kg(2,867 lb) and a maximum digging depth of 2.3m(7.6ft).The standard configuration features a canopy and retractable

undercarriage. The E16 is available in two versions. The base model with fixed undercarriage has an operating weight of 1,515 kg(3.333lb) for the canopy configuration and offer a maximum digging depth of 2.42m(7.9ft). With the optional factory installed retractable undercarriage and long dipperstick, the E16 has an operating weight of 1,555kg(3.421lb) for the canopy configuration and offers a maximum digging depth of 2.6 m(8.5 ft).

The digging force, combined with the working range, the smoothness of the functions in the workgroup including the boom and dipperstick, and the hydraulic performance in cycle times are among the main freatures of the E14 and E16 min excavators. Their compact size and superior stability make there machines ideal for heavy duty applications in confined areas.

Also in this weight class, Hitachi has launched the 1,5 tonne ZX14-3 excavator. Described as a “basic no-nonsense model that is extremely easy to operate” the ZX14-3 uses a three cylinder 10.7kw engine and a large 22 liter capacity fuel tank to increase operating time. Operating weights range form 1.46 to1.6 tonnes.

According to Joep Van Den Maagdenberg, product sales representative for Hitachi’s compact line, the new mini is simple in design but also features a standard of operator comfort not normally found in this size machine.

Wacker Neuson has added the 2.4 tonne 2404 machine to its range. According to sales manager Gerhard Neudorfer: “The objective we had was to develop a powerful, efficient and robust machine which also addresses a price-conscious clientele and which could easily hold its own with machines in the 2.5 tonne class. Our designers have achieved this with aplomb and we see massive potential for this 2.4 tonne excavator.” The 2404 offers a dig depth of 2.6 m(8.5ft), a dump height of 2.8m(9.2ft) and a 1.2 tonne lift power.
