Deskripsi Tentang Excavator



Hydraulic Excavator merupakan salah satu jenis dari alat berat yang pada dasarnya digunakan dalam pekerjaan construction (konstruksi) dan mining (pertambangan). Alat ini digunakan untuk menggali (dig), memuat (load) dan memindahkan (move) tanah, pasir, batu-batuan dan bahan tambang lainnya. Dalam perkembangannya (pasca Asia economic crisis), Hydraulic Excavator tidak hanya difungsikan pada pekerjaan-pekerjaan konstruksi dan pertambangan saja, namun sudah merambah ke sektor perkayuan (logging) dengan menggunakan attachment Rotary Log Grapple. Rotary Log Grapple (RLG) merupakan salah satu attachment pada hydraulic excavator yang berfungsi untuk pekerjan loading dan un-loading kayu.




Kinematika Excavator

Excavator adalah salah satu alat berat yang mampu bekerja pada berbagai
kondisi. Pekerjaan yang dilakukan pun berbagai macam, dari pekerjaan menggali,
mengangkut dan memindahkan. Sehingga alat ini akan sangat mempermudah kerja
manusia dalam suatu pekerjaan yang sangat besar. Pada tulisan ini penulis akan
menjelaskan berbagai macam tentang Excavator dan pembahasan tentang analisis
kinematika pada lengan excavator yang merupakan jenis manipulator dan lebih
dikenal dalam dunia robotic. Perhitungan kinematik pada lengan atau manipulator ini
akan menghasilkan posisi dan orientasi setelah atau pada saat sebelum melakukan
kerjanya. Dalam hal ini akan dicari persamaan kinematika maju dengan menggunakan
konvensi Denavit – Hartenberg untuk mencari titik end effector dari manipulator dalam
bentuk persamaan matriks.

Excavator Sales May Rise 25% as China Fuels Demand, Kayaba Says

May 19 (Bloomberg) -- Global sales of excavators may rise 25 percent because of demand from China, Kayaba Industries Co. said, twice as much as the Japanese company’s forecast.

Industry demand may rise to about 200,000 units in the year started April 1, Makoto Kimura, director in charge of marketing for hydraulic components at the Tokyo-based parts maker, said in an interview yesterday.

Demand for the digging machinery in China is being driven by an expansion in mining projects to fuel the world’s fastest growing economy as well as spending on rural infrastructure. China, the world’s largest market for construction equipment market, may account for 60 percent of excavators sold globally, according to Kayaba.

“Excavator sales have reached unprecedented levels,” Kimura said in the interview. “Customer needs for the machines are exceeding what we have budgeted.”

Kayaba, which holds a 40 percent of the world’s market for excavator cylinders, estimated growth of about 13 percent in the market in February.

The shares of Kayaba, which is also known as KYB, were unchanged at 350 yen at 1:06 p.m. on the Tokyo Stock Exchange.

The company supplies parts to Tokyo-based Hitachi Construction Machinery Co., Caterpillar Inc., the world’s largest construction machinery maker, and China’s Sany Heavy Industries Co.

The number of excavators sold in China doubled to about 64,000 units in the first four months of 2010 from a year earlier, according to Kayaba estimates.

Kayaba’s Chinese unit will install additional lines to expand production capacity of cylinders by 50 percent to meet demand, Kimura said.

Komatsu Ltd., the second-biggest construction machinery manufacturer, expects sales of large dump trucks and excavators used in mining will rise by half because of demand from China, Kazuhiko Iwata, the president of the company’s mining division, said on March 12.

Komatsu’s America Sales May Rise 30% From October on Housing

By Masumi Suga and Takako Iwatani

May 31 (Bloomberg) -- Komatsu Ltd., the world’s second- largest maker of excavators, expects North American sales to expand about 30 percent in the fiscal second half as U.S. housing investment recovers, President Kunio Noji said.

There are “many positive signs” in the region, Noji said in a May 28 interview at the company’s Tokyo headquarters. “Previously, when housing demand recovered, machinery sales typically grew at a pace of 30 to 50 percent.”

Komatsu seeks to benefit from a construction rebound in the U.S. as housing prices recover from the mortgage-related collapse of Lehman Brothers Holding Inc. Since the financial crisis, China has become Komatsu’s largest market, with sales surging almost fourfold to 19 percent of total revenue in the past fiscal year, compared with 5.3 percent as of March 2006.

U.S. “consumer spending has recovered near the level before the Lehman shock,” Noji, 63, said. North America was Komatsu’s largest market until 2007.

China now accounts for half of global excavator sales, up from 27 percent in the year ended March 2009, according to rival Tokyo-based Hitachi Construction Machinery Co. China’s investment in roads, railways and buildings has driven demand for heavy machines, especially in the nation’s interior regions, Noji said. Komatsu’s excavator sales in China may almost double this quarter from a year earlier, he said.

Komatsu forecast in April profit will almost triple in the fiscal year ending March 31, 2011, to 90 billion yen ($985 million). The forecast is still less than half the 2007 peak of 209 billion yen. The company swung back to profitability in the last quarter of the year ended in March.

Komatsu shares have fallen 12 percent this year, compared with a 7.6 percent decline in the Nikkei 225 Stock Average. The stock fell 0.8 percent to 1,701 yen at the 11 a.m. break on the Tokyo Stock Exchange today.

‘Positive Signs’

Construction machinery sales in North America rose 4 percent in April from a year earlier, the first increase in three and half years, according to an April 24 report released by Nomura Securities Co. The gain reflected demand for equipment used to mine coal, while demand for machines for home buildings remained at “low levels.”

Caterpillar Inc., the world’s largest maker of bulldozers and excavators, said last month the U.S. economy may expand 3.5 percent, while developing countries may grow more than 6 percent in 2010.

California house prices rose 21 percent in April from a year earlier as distressed properties made up a smaller share of inventory on the market, the state Realtors group said May 24.

Hybrid Excavators

Komatsu, aiming to lead the industry in hybrid technology, may sell as many as 500 hybrid excavators in China this quarter, Noji said. The company set a target of 2,000 units in China and another 1,000 units elsewhere by March 2011.

The company will start selling hybrid excavators globally this year, adding North America, Europe, and several emerging Asian nations to its markets, Noji said.

A new model will be released this fiscal year, and will be priced lower than existing models, the CEO said, without elaborating. Komatsu introduced what it calls the world’s first hybrid excavator in 2008 for the Japanese market. The excavator is designed to consume 25 percent less fuel than standard models.

Dan Rather reports on trucking

By Jill Dunn

Newsman Dan Rather devotes his program to trucking tonight, June 8, in “Haul or High Water,” riding through five states with a long-haul trucker.

Rather rode with Don Wagner of Nevada, who got into trucking later in life and loves it, despite the bills piling up and few home visits. His wife, Leslie, runs Wagner’s Trucking at the home, booking hauls.

In 2005, the average trucker was earning just more than $35,000, or 30 percent less than before deregulation, while owner-operators average $22,000. Investors and freight brokers make the major profits in trucking, Rather noted.

"Dan Rather Reports – Haul or High Water" airs on HDNet at 8 p.m. EDT and will re-air at 11 p.m. HDNet is avilable on AT&T, Charter Communications, Dish Network and DirecTV, among others.
