Caterpillar Foundation Announces Commitment to Help Fight Racism and Social Injustice

DEERFIELD, Ill. – The Caterpillar Foundation, the philanthropic arm of Caterpillar Inc. (NYSE: CAT), today announced a commitment to help fight racism and social injustice.

To honor the lives lost and keep with its mission, the Caterpillar Foundation is donating $1 million split between the following two organizations ($500,000 each):

  • The Equal Justice Initiative is committed to ending mass incarceration and excessive punishment, challenging racial and economic injustice, and protecting fundamental human rights for the most vulnerable in our society.
  • The NAACP Legal Defense and Educational Fund, Inc. seeks structural changes to expand democracy, eliminate disparities and achieve racial justice in a society that fulfills the promise of equity for all Americans.

“Caterpillar supports the fight against racism and injustice,” said Chairman and CEO Jim Umpleby. “Caterpillar and the Caterpillar Foundation look forward to working with the Equal Justice Initiative and the NAACP Legal Defense and Educational Fund to help build a better world.”

The Foundation will continue investing in community programs that address the destructive effects of racism and the fight for equal justice.

Through its existing U.S. Matching Gifts Program, the Caterpillar Foundation is also matching employee and retiree donations to eligible organizations that are most important to them, their families and the communities in which we live and work in the fight against racism and social injustice. 

LIVING OUR VALUES IN THE FIGHT AGAINST RACISM AND INJUSTICE

Chairman and CEO Jim Umpleby shared the following message with employees:

I do not usually communicate with you about non-business issues, but I cannot remain silent in the wake of recent events. I am struggling with outrage, sadness and frustration at the tragic death of George Floyd, which followed so closely on the deaths of Ahmaud Arbery and Breonna Taylor. We grieve for Mr. Floyd and his family and friends as well as for the larger community of which he was a part.

People of color in the United States are too often denied basic human rights that many of us take for granted. Everyone deserves to be treated with dignity and respect and have access to equal justice. Racism has no place in a civilized society.

I know many of you are also dealing with your own range of emotions in response to these recent events, and others might be struggling to fully understand the anger and frustration we are witnessing in communities across the country. These tragedies present us with an opportunity to listen and work to understand the experiences and perspectives of those who have suffered the destructive effects of racism.

As Caterpillar employees, Our Values in Action require each of us to respect all people and their opinions, experiences and backgrounds. I ask you to reflect on your individual thoughts and actions and ensure they are consistent with Our Values.

In addition to our individual actions, Caterpillar will support the fight against racism and injustice. In honor of the lives taken and with a mission to help build a better world, the Caterpillar Foundation will make a donation to an appropriate organization that will be announced in the near future. I also encourage you to take advantage of our Caterpillar Foundation Matching Gift Program to support those organizations most important to you, your family and your communities in the fight against racism and injustice.

Thank you for living our Caterpillar Values every day.

Jim Umpleby
Caterpillar Chairman & CEO

35 Years. 175,000 Machines. 1 Big Innovation

Thirty-five years ago, Caterpillar launched the H-series which brought the elevated sprocket or “high drive” concept to the Cat® medium track-type tractors (MTTT). In May, we celebrated the production of the 175,000 elevated sprocket MTTT – an achievement of manufacturing, innovation and customer-focus.

In 1985, the team introduced the H-series medium track-type tractors. For our customers, immediate benefits included improved durability and ease of service of the powertrain components. The medium tractors took advantage of one additional high drive benefit – the ability to extend the tracks forward or rearward to optimize tractor balance for unique applications. The D4H and D5H also combined a six-way adjustable, VPAT (Variable Power Angle Tilt) blade with the high drive undercarriage for the first time. These early high drive tractors pushed the levels of efficiency, productivity and ease of operation. All of these were – and still are – our Cat product advantage.

Since the H-series tractors were introduced, Caterpillar has continued to improve dozers and develop innovative solutions for customers. One of the first customers to operate a Next Gen D6 XE, a long-time earthmoving contractor, was astonished by the power and maneuverability and commented, “It is beyond what I thought was possible.”  There can be no better confirmation that today’s engineers are upholding the tradition of the original high drive tractors and going “Beyond Known Capabilities.”

Another way we’re helping customers with Cat’s Next Gen Dozers? A return to a family approach. Like the H-series, there are commonalities between medium dozers. For example, the D5, D6 and D7 share a common cab layout, which simplifies training for dealers and customers so operators can get up to speed faster. An added plus – the new cab is larger and more comfortable for operators. The new D7 also returns to the high drive configuration, leveraging scaled designs from the D8T. Even the nomenclature, D4-D7, are realigned with the numerical values used with the H-series.   

To commemorate the 175,000 MTTT high drive milestone, we produced three special edition tractors. Check them out:

Caterpillar Unveils New Range of Excavators in India

According to company officials, the machines offer up to seven per cent more hydraulic power, 15 per cent less consumption and five per cent lower maintenance cost.

Manufacturer of construction and mining equipment, Caterpillar unveiled a new generation of excavators manufactured at its facility on the city outskirts. The next generation 20-ton size class excavators, Cat 320D3 and Cat 323D3 are produced at the company’s manufacturing unit at Thiruvallur. According to company officials, the machines offer up to seven per cent more hydraulic power, 15 per cent less consumption and five per cent lower maintenance cost.

“To cater to the demand of our customers for a more reliable and more powerful heavy-duty excavator equipped with state-of-the-art technology, we have launched these two Next Generation 20-ton size class excavators..”, Caterpillar India, Director-Sales and Marketing, Gurman Reen said.

The 320D3 fits road contractor and construction customers demand for low owning and operating costs. It consumes 15 per cent less fuel than its predecessor 320D2 and also comes with 5 per cent lower maintenance cost, he said. Caterpillar currently has state-of-the-art manufacturing facilities in Thiruvallur and Hosur in Tamil Nadu apart from units in Maharashtra.

Cat introduces Ultra High Demolition machine

Caterpillar’s new 352 UHD Ultra High Demolition excavator is designed to handle difficult demolition of tall structures.

It uses a range of Cat demolition attachments, including multi-processors, grapples, shears and hydraulic hammers with the retrofit boom.

The UHD front can be switched for a straight or bent (retrofit) boom position for lower-level demolition and earthmoving applications. This switch typically is done in about 15 minutes with two people with no special tool required, Cat says.

The 352 UHD features a variable-gauge undercarriage (hydraulically activated), as well as the Cat Active Stability Monitoring system, which warns when approaching stability limits.

In the UHD configuration, the 352 UHD provides 28 metres of vertical height to the work tool attachment pin, and 15.8 metres of horizontal reach, when working with a 3,700 kg tool. These specifications allow the 352 UHD to demolish structures eight or nine stories high. Undercarriage gauge is 4.0 metres when working, 3.0 metres for transport.

In retrofit straight boom configuration, the 352 UHD uses a 9.1-metre retrofit boom with a choice of 2.9-metre or 3.35-metre retrofit stick. Equipped with the longer stick and a 3m3 bucket, the 352 UHD has a digging depth of 6. 670 metres and a maximum reach at ground level of 11.88 metres.

The 352 models use the Cat C13 engine, rated at 304 kW, meeting the EU Stage V emissions standard. The C13 also is capable of operating on biodiesel up to B20. Three power modes in the machines allow the operator to match machine performance to the task at hand, and a hydraulic reversing fan cools the engine on demand to help reduce fuel consumption.

When using the retrofit boom, the machine can use the Cat GRADE with 2D grade control system, swing e-fencing and the Cat Payload on-board weighing system. The Payload system can be used with Vision Link (online telematics interface) to remotely manage production targets via the machine’s Product Link telematics system.

Inside the cab, each joystick button can be programmed, including power mode, response, and pattern, and these settings can be recalled using appropriate operator identification. An automatic hydraulic oil warmup feature quickly brings the system to operating temperature and helps prolong component life. The 10-inch (254mm) touchscreen monitor includes operating and maintenance tutorials. 

Cat rolls out new skidders

Caterpillar has brought out a new line of 16 D3 series skid steer loaders and compact track loaders.

The D3 Series models support a line of new ‘smart’ attachments, which Cat says is an industry first. The technology recognises certain attachments and tailors the controls and operator information accordingly, to match the tool and the task.

Compared to the older D and D2 models, the D3 Series loaders have a wider opening cab door. Additionally, the distance between joystick pods has increased by 76 mm to give more wriggle room in the cab.

Stability of the compact track loaders (CTLs) has been improved through changes to the undercarriage frame and torsion axles reduce machine pitching and rocking.

All Cat D3 Series CTLs have standard two-speed travel. The Cat 279D3 and 289D3 loaders reach a top speed of 8.4 mph (13.6 km/h), which is 20% faster than the older models. The Cat 239D3 and 249D3 models are now built with two-speed transmission as standard, versus the previous single speed, increasing travel speed by 9% aligning these models with the rest of the two-speed equipped CTL model range.

Control features on both the D3 CTLs and skid steer loaders (SSLs) include Return-to-Dig and Work Tool Positioner to assist operators with repetitive tasks like grading, digging, and loading. These items are now bundled together with the dual direction self-level feature.

In conjunction with the D3 Series introduction, the previous XHP performance model identifier used with the 272 and 299 models has been replaced with XE badge. The 272D3 XE and 299D3 XE models represent the top of the range in the Cat SSL and CTL line.

History Archive: Historical Construction Equipment

It’s easy to forget that just a few hundred years ago Australia once had no skyscrapers or train lines, much like the rest of the world. The last hundred years has seen an exponential increase in the size, productivity and efficiency of earth moving equipment. Construction equipment has literally changed the shape of the planet; building canals, digging up mountains and flooding valleys with dams. In this article, we will discuss how construction equipment has evolved over time.

Before Modern Records

Nobody is quite sure who invented the shovel, the pickaxe and the hoe, but these instruments surely revolutionised the way work was carried out. There is even some evidence to suggest that these devices were invented in different places, at different times, in different iterations. The functions they provided would have drastically increased the efficiency and productivity of agricultural tasks, leading to increased yields and the ability to support larger populations.

The Days of Horsing Around

Historical records of Rome, and what is now called Europe, provides evidence of animal-integrated construction. Horses, donkeys and oxen were regularly employed to drag materials, assist in the construction of roads, and provide mechanical advantage to foundries and granaries.

Steam Changed Everything and Diesel Changed it Again

The first versions of the bulldozer, dump truck and tractor were horse-drawn apparatuses. Engineers were quick to realise the power of the steam engine, and it wasn’t long before work animals were replaced. Steam power ran across the world, bringing with it the power of the train and quickly opened new areas to agricultural and mining. The advent of the internal combustion, and eventually the diesel engine, revolutionised construction equipment once again, as it was much cheaper than petrol and provided easily portable power to machines around the world.

Caterpillar Tracks

As the power of engines and demands of industry grew, construction vehicles became bigger, capable of moving ever increasing loads. The rigid wheels of the late 19th and early 20th centuries were not well matched to handing the varied landscapes of the world, and frequently got bogged as a result. Caterpillar tracks hit the market through a series of innovations by different inventors around the world, and suddenly construction machines could go almost everywhere. Caterpillar tracks are still the popular choice for a lot of earth moving equipment, such as excavators.
