Three people were injured Monday, one of them seriously, when a mob of villagers threw stones at a construction crew they say were intent on destroying their homes.

The injured were a local village official and two bystanders, witnesses said, but their identities were not known.

A representative of the construction company 7NG said Tuesday a large truck carrying a bulldozer on a trailer broke down in front of a village in Chamkarmon district, Phnom Penh, whose residents began throwing stones at the crew.

Villagers say the crew was in the process of unloading the bulldozer, a common piece of demolition equipment in the growing problem of land grabs across Cambodia.

Rights investigator Chhim Savuth, of the Cambodia Center for Human Rights, said a truck towing a bulldozer had stopped in front of the village and appeared to be backing up in preparation for unloading.

“The villagers alleged that it would destroy their homes,” he said. “Hundreds of villagers set fire to tires and threw rocks on the equipment that was about to go down, resulting in broken glass, but the driver escaped injuries.”

Srey Sothea, president of 7NG, said the company was not going to have anyone arrested. But he said the transportation of the equipment should not excuse “the intention to assault” shown by the villagers.

“Usually the destruction [of homes] is not my capacity,” he said. “Daring to destroy 100 homes? How can we do it? It would require the participation of, the formation of, an appropriate coalition commission. Going alone without the knowledge of the authorities, not even a police officer would know about it.”

Caterpillar Incorporated, also known as Caterpillar is a United States based corporation that is based in Peoria, Illinois. The company commonly known as Caterpillar is known around the world as the largest manufacturer of construction and mining equipment, diesel and natural gas engines, and industrial gas turbines. Well known and famous for their products that feature the Caterpillar track and distinctive yellow paint, Caterpillar produces a wide range of heavy equipment for all types of jobs, including the very popular Caterpillar D9 bulldozer. History The story of Caterpillar dates back to the late 19th century, when Daniel Best and Benjamin Holt were experimenting with different ways to fulfill the promise that steam tractors held for farm work. Prior to 1925, the Holt family had pioneered track tractors and gasoline powered engines. After the companies of Best and Holt were merged, the company went through several changes then at the end of World War 2, they began to grow at a very fast pace, launching the first venture outside of the country in 1950, which marked the beginning of Caterpillar development into a big corporation.

Caterpillar equipment ranges from track type tractors to hydraulic excavators, backhoes, motor graders, off road trucks, wheel loaders, tractors, diesel and gas engines, and gas turbines. Caterpillar equipment is used in construction, excavation, building roads, mining, energy, forestry, transportation, and material handling companies. Sales Over half of Caterpillar ’s sales are to customers in overseas areas. Caterpillar products are sold in almost 200 different countries. The company has a worldwide network of over 200 dealers - 63 in the United States and over 150 in other countries. Caterpillar equipment and components are manufactured in 42 plants in the United States and 58 plants in Australia, Belgium, Brazil, Canada, England, France, Germany, India, Japan, Mexico, and several other countries. Labor Caterpillar almost went down in the early 1980s due to the massive union strikes and a down turn in product demand. At the time, several news reports indicated that products were piling up so high in facilities that temporary workers hired to work the lines could barely get to their stations to perform their jobs. In the 1990s, Caterpillar suffered yet another long strike in which the company hired what it deemed to be permanent replacements for union workers that were on strike. During both strikes, jack rocks were placed in the home entrances of many of CATs top executives and employees, puncturing the tires of their vehicles and making things worse for the company. Not long after the strike of the 1990s ended and the economy started to get back up again, Caterpillar adopted the “6 Sigma” quality management program, to help reduce costs and inventory and identify and correct the defects in processes and products.

Gary Blackwell was not a happy man when he arrived at work on Friday morning.
For the past eight weeks, his company, Blackwell Excavating, has been working on a dairy conversion on Thompsons Track without a problem.

But overnight on Thursday, a person or persons entered the property where machinery being used in the conversion had been left and vandalised two graders, a digger and a diesel tanker, causing thousands of dollars worth of damage.

Every window was smashed and fuse boxes and the diesel tank were tampered with and Mr Blackwell was getting a mechanic out to find out whether any of the engines had been interfered with.

The machinery was visible from the road, but the culprits wouldn’t have had an easy job getting on to the property, Mr Blackwell said.

He believed the Blackwell Excavating machinery and that belonging to Ellesmere firm Densem Contractors Ltd may have been deliberately targeted for reasons unknown to him.

“They’ve made a special effort to get in here because it’s not easy,” he said.

“It is visible from the road but you’ve got to find the gateway to get in.”

The machinery was parked about 1km off the roadside and there was a small culvert crossing that was only installed on Thursday, that even those working on the site had to really look for to find. Even once on the property, there were water races and other farm obstacles to get past before reaching the machinery, so those responsible were likely to have been in a 4WD.

While the cost of the damage caused was believed to be in the thousands, it also meant no work could be done on the conversion on Friday and Mr Blackwell believed he and his fellow workers would not get going again until today.

Police were alerted and a glass company was called to try and replace the windows as soon as possible, Mr Blackwell said.

It was the first time Mr Blackwell’s business had been the victim of such an attack and although he said it was always on the cards when machinery was left parked at a work site, those responsible for Thursday night’s appeared to have targeted the site.

A worker found the damage when he arrived at work at 7.45am on Friday after the last workers would have left the area at about 6.30pm on Thursday.

But with Thompson’s Track being a busy route, it was hoped that someone may have seen or heard something that could lead to the apprehension of the culprits.

Siemens announced it was forming a joint venture with Russian heavy machine maker Uralmash for constructing plant for the Russian metals and mining industries. The German engineering concern announced at its Munich headquarters it was to take a majority stake through its subsidiary, VAI Metals Technologies, of 50 per cent plus one share in the new company.

Uralmash, based in Yekaterinburg, makes heavy machinery for the Russian mining, metallurgical and electricity production sectors.

Siemens has long held a blocking minority in the Russian company Power Machines, but has been prevented by the Russian authorities from taking a controlling stake.

Earlier this month, Siemens announced it had secured a contract from Power Machines for the supply of components for the Urengoiskaya and Kirishi projects in Russia.

The German company sees itself as “market leader in Russia in the field of gas turbine technology.”

Compact wheel loaders with 65 net horsepower and less account for an expanding share of the small-machine market.

Perhaps you’ve noticed in the last five years or so that an increasing number of prominent brand names have been showing up on small wheel loaders. Some might say that these “compact” loaders are relatively new to the North American market, the result of marketers noting the success of these machines on congested European jobsites and bringing the concept here.

But, just to set the record straight, small wheel loaders aren’t a new phenomenon on this side of the Atlantic. The once-mighty International Harvester, for example, was building small wheel loaders for worldwide consumption in the mid-1960s, and brand names such as Waldon, Swinger, Power Trac and TCM have endured successfully in the U.S. market.

That said, however, there’s no denying that the North American market has rediscovered the compact wheel loader in recent years, as evidenced by the expanding number of suppliers and the corresponding rise in sales numbers. And with this rediscovery has come a new generation of machines, which skillfully concentrate the power and versatility of larger loaders into much smaller packages.

Our introduction to the design specifics of today’s small wheel loaders came a year or so ago when Volvo loaned Construction Equipment an L20B for an installment of Hands-On Earthmoving. The 56-horsepower L20B features dual-range hydrostatic drive, parallel-lift loader linkage, standard auxiliary hydraulics, choice of proprietary or universal coupler (both hydraulic) and operator amenities that include a multi-function joystick with built-in switches for transmission control and for ground-speed control independent of throttle position.

According to David Morice — heavy-line sales manager for JCB, whose 67-net-horsepower models 407ZX and 409ZX just missed our cutoff — the small wheel loader’s market success is establishing a trend toward even more design enhancement, including such features as high-flow auxiliary hydraulics, more precise return-to-dig systems and ride-control.

At the heart of their design, compacts neatly insert conventional wheel-loader features — efficient truck loading, load-and-carry capability, smooth ride, stability, friendly steering, roomy cab and attachment-handling ability — into packages of more application-accommodating size. Wheel-loader buyers simply have more choice now for matching machine size to the needs of a given operation.

Basic designs and features

The size of compact wheel loaders within the horsepower class (65 net and less) that this report addresses varies considerably. Operating weights range from less than 1,500 pounds to more than 12,000 pounds, net horsepower ratings from the low twenties to 65, and hinge-pin heights from around 105 to nearly 130 inches. Despite the wide variations, these machines do, however, exhibit general similarities.

Most, for example, are hydrostatically driven, usually with the combination of a single high-pressure, variable-displacement hydraulic pump and single hydraulic motor. The motor in most units drives through a mechanical gearbox to conventional planetary axles, which often use sealed, wet-disc brakes. Maximum travel speeds may range from the low teens to 25 mph.

Most also employ articulated-frame steering, but with notable exceptions. Gehl and Mustang units (except for the articulated Gehl AL20DX) feature all-wheel steering in conjunction with their one-piece frame. The Deere 244J is a hybrid of sorts, incorporating both articulated-frame steering and rear-wheel steering — a system Deere calls Stereo Steering.

Implement-hydraulic systems are typically gear-pump systems, and an auxiliary hydraulic system (providing flow to powered attachments) often is available. These auxiliary systems, however, usually don’t produce oil flows that compare with the output of high-flow systems in large skid-steers. Although this limitation might preclude the use of certain attachments, many hydraulically powered tools can still be used. According to Caterpillar, for instance, its model 904B, with a 22-gpm auxiliary system, can handle trenchers, snow blowers, stump grinders and cold planers.

The question buyers should ask in this regard, though, is whether the auxiliary flow in the specific wheel loader model being considered is sufficient to power attachments intended for use with it.

Attachment use

It’s probably safe to say that when the new generation of compacts began appearing, available attachments, in many instances, were limited to pallet forks and specialty buckets — such as multi-purpose, side-dump and stone-sieve types.

Even though many of these machines were equipped (or could be equipped) with a universal (skid-steer) type coupler, manufacturers generally were cautious about recommending the use of skid-steer attachments with compact wheel loaders. Since many compacts use Z-bar loader linkage (or a variation thereof), which typically generates considerably higher breakout force than does skid-steer-loader linkage, the concern was that these stronger machines would structurally overpower attachments designed for skid-steers loaders.

“Placing a skid-steer bucket on a compact wheel loader is not a good idea,” says Georg Seyrlehner, Ingersoll Rand’s product manager for earthmoving equipment. “Given the wheel loader’s greater breakout force, there’s potential for damaging both the bucket and the coupler.”

As the market has matured, however, more attachments have been developed specifically for the compact wheel loader, further expanding its versatility.

“Specialty buckets and forks still remain the most popular attachments,” says product manager David Wolf at Case, “but brooms, augers and ground-conditioning attachments, for example, are now generally available.”

The best advice about using skid-steer tools on a small wheel loader is to ask your dealer if a specific attachment’s structural strength and (if powered) its hydraulic flow and pressure requirements are a match for the wheel loader in question.

In addition, buyers should be aware of two other considerations related to attachment use with small wheel loaders: coupler type and loader-linkage type. Regarding couplers, some manufacturers equip their compacts with only conventional wheel-loader-type couplers, others use the universal-style coupler, and still others use the conventional coupler, but offer a universal-style adapter.

Loader linkage is typically either standard Z-bar or parallel-lift. The latter automatically keeps pallet forks level from ground level to full lift, which is handy if the machine frequently works with forks. Depending on the specific linkage, however, the parallel-lift configuration may sacrifice a bit of digging force. But not always; some manufacturers claim linkages that competently blend the best qualities of both linkage types.
