Komatsu’s PLUS (Parallel Link Undercarriage System) rotating bushing undercarriage is now available as an option on D85EX/PX-18 dozers.

Each of the three different shoe widths are available: 24, 26 and 28 inches. The PLUS system is designed to provide up to twice the life of a conventional undercarriage, lowering repair and maintenance costs by up to 40 percent in certain applications, Komatsu says. PLUS also eliminates the downtime of pin and bushing turns. All components are designed for equal wear life. PLUS uses oil lubricated, rotating bushings that are free to rotate, unlike fixed bushings used colombia bogota on conventional undercarriage systems.

Additionally, the PLUS undercarriage assurance program covers leakage and breakage due to defects in material or workmanship for 3 years or 4,000 hours, whichever occurs first.

Latest Cat 340F excavator offers higher levels of operator comfort, safety and fuel efficiency

CATERPILLAR have announced the launch of their new 340F excavator which features a spacious operators station, heavy-duty main structures for long-term durability and fuel-saving systems that reduce operational costs in a range of applications.

The Stage IV-compliant excavator is powered by a Cat C9.3 ACERT engine that delivers 226kW (310hp), while its powerful hydraulic system, with a maximum flow of 570 litres/min, provides high digging and lifting forces, as well as ample power for hydro-mechanical work tools.

The machine offers two power modes – standard and economy – allowing operators to select the appropriate engine speed to match the given application. The 340F unit is also equipped with automatic engine speed control which adjusts rev/min to match the excavator’s operating load, and an engine-idle shutdown system that stops the engine after a pre-set idling interval. These systems not only minimize fuel consumption, but also reduce emissions and extend service intervals.

The new 340F excavator incorporates Caterpillar’s SmartBoom technology, which increases productivity by reducing stress and vibration transmitted to the machine during operations such as rock scraping and hammering.

For overall system efficiency, major hydraulic components are located in close proximity – allowing shorter connecting tubes and hoses that reduce frictional losses and pressure reductions. The result, say Caterpillar, is reduced loading on the system for added fuel savings. The main control valve is designed to respond proportionally to control lever movement for precise control of hydraulic functions.

Fitted with a heavy-duty 6.5m reach boom and 3.2m stick, the 340F excavator has a maximum digging depth of 7.48m. An optional mass-excavation boom can be paired with a 2.55m stick for high production in large-scale earthmoving and heavy-material applications.

The Cat machine’s heavy-duty undercarriage provides a stable working base for excavating and lifting. Track chains are grease-lubricated to reduce internal pin and bushing wear, thereby extending undercarriage life and reducing travel noise.

Joystick controllers in the ROPS cab are mounted in height-adjustable consoles that complement the armrests and a fully adjustable, high-back seat. The cab’s large glass areas improve visibility, while special sealing and insulation help keep the operating environment clean and quiet.

For enhanced serviceability, routine maintenance points, caterpillar colombia bogota such as fluid taps, filters and drain tubes, are easily accessible from ground level. And service-compartment doors have been specially designed to prevent debris entry and latch securely in the open position for machine maintenance.

The 340F excavator is supported by Caterpillar’s LINK technologies specially developed for fleet owners looking to increase productivity and reduce operating costs by tracking critical information (eg machine location, hours, fuel usage, idle time etc.) via the online VisionLink interface.

Yanmar Construction Equipment Europe has introduced its new range of compact wheel loaders for the first time in Europe.

The V7 and V8 models are being shown exclusively at Germany‘s NordBau exhibition on the stand of the Yanmar partner HKL Baumaschinen.

In developing the new wheel loaders, quality was the key factor for Yanmar. The wheel loaders driven by Yanmar engines, which are known for their reliabilty and low fuel comsumption. Furthermore, only robust components from well-known suppliers were used.

The V7 model with an operating weight of 4100 kg offers a payload of 1800 kg, the V8 model with an operating weight of 4350 kg offers a payload of 2100 kg.

The special structure of the rear frame yanmar colombia bogota and the engine mounted in line guarantee best access to all service and maintenance points.

The hydraulic quick coupler combined with the standard working hydraulics system facilitates the use of different attachments, and the operator can easily switch between standard bucket and pallet fork without leaving the cabin.

Doosan has launched three new Tier 4-compliant crawler excavators to its lineup. The DX180LC-5, DX225LC-5 and DX235LCR-5 replace the Tier 4 Interim-compliant Dash-3 models and add feature performance and comfort improvements to a range of features.
We first got a look at these machines during a media event in the Arizona desert back in March and Doosan has now officially made them available along with a few additional details about each machine.
Specs
DX180LC-5
DX180LC-5
The DX180LC-5 is powered by a Perkins diesel providing 129 horsepower. The 43,224-pound machine has a 29-foot 7-inch max digging reach, a 20-foot max dig depth and a 21-foot 3-inch max loading height.
The 22-metric-ton DX225LC and the 23-metric ton DX235LCR reduced tail swing model are powered by Doosan engines providing 162 and 181 hp, respectively. Max digging reach on the 225 is 31 feet, 10 inches, and 31 feet, 7 inches on the 235. The machines feature 21-ft., 7-in. and 21-ft., 10-in. digging depths; 22-ft., 5-in. and 26-ft. loading heights, respectively
A super long reach configuration for additional dig and depth is available for the 225, boosting reach to 50 feet, digging depth to 38 ft., 2 in. and loading height to 35 ft., 6 in.
Smarter power
In addition to four power modes and four work modes, the excavators feature Smart Power Control, a new selectable feature made up of two systems that work together to boost machine efficiency and reduce fuel consumption.
The first, Variable Speed Control, reduces engine rpm during low workload requirements, reducing the total energy required and improving fuel efficiency by between 3 and 7 percent. Second, Pump Torque Control improves machine efficiency by matching hydraulic pump torque and engine response to the job at hand, which prevents engine overload as well as excessive fuel consumption.
Another fuel-saving upgrade to the machine is auto-shutdown. Idle time can be configured for between 3 and 30 minutes, and the feature will shut down the excavator’s engine when the preset idle time is met.
New display, design updates
dsc01472The machines also feature a new and improved 7-inch LCD screen that enables operators to monitor excavator performance data and critical machine diagnostics side-by-side with the rearview or (optional) side-view camera image. When the side camera is equipped, a split-screen view allows the operator to view both the rearview and sideview cameras simultaneously.
Additional machine updates include improved anti-skid plates that allow for easier engine access, a relocated emergency engine stop, improved serviceability, an upgraded alternator and a new front window design that boosts visibility to the work area. Plus, on the 225 and 235, Doosan has added a backfill blade package.
Available factory-installed options include a straight travel pedal, two-way auxiliary hydraulic pedal in addition to joystick control, a diesel powered coolant heater for cold starts, cab guarding for special applications and colombia bogota an intelligent floating boom.

All three machines comes with a standard three-year subscription to the company’s telematics service which allows remote monitoring of machine data such as location, hours, fuel usage, engine idle versus work time, error codes and engine and hydraulic temperatures. The system also allows Doosan dealers to respond to machine warning messages and alerts and remotely troubleshoot issues that arise in the field

Similar to the log loader, the main update to the machine is a new engine, producing 7 more horsepower while consuming 6 percent less fuel than its predecessor. The PC210LC-11 is powered by a Komatsu SAA6D107E-3 Tier 4 Final engine generating 165 hp. Also new to the machine is a viscous fan clutch which improves cooling system efficiency and reduces noise levels. RELATED >> Komatsu intros PC210LL-10 log loader with power boost, redesigned cab In-cab noise has been decreased as well, down two decibels. Operators will also find updates to the machine’s 7-inch LCD monitor including a new split-display allowing a from the rear camera alongside gauge data. Meanwhile, a standard pattern change valve makes it easy to switch joystick patterns to accommodate specific operator preferences. The machine features three travel speeds and six work modes as well as a standard 9,634-pound heavy counterweight for improved over-the-front and over-the-side lift capacity. The PC210LC-11 is equipped with the company’s telematics system, Komtrax, which allows operators and fleet managers to keep up with the machine’s fuel levels, operating hours, location and gives you cautions and maintenance alerts via a website or a smartphone. Additionally, Komtrax now monitors DEF levels, ambient air temperatures and pressures. Komatsu CARE is provided on the machine for the first three years or 2,000 hours, and includes scheduled factory maintenance, a 50-point inspection at each service, and two DPF exchanges and DEF tank flushes in the first five colombia bogota years.

In 2012 when Caterpillar first unveiled it’s 336EH hybrid excavator, the company spokespeople offered only vague notions about how and when they might deploy this new technology on other excavators.
But at a press event last week in Tinaja Hills, Arizona, Cat showed us not only it’s newest hybrid machine the 336F L XE , but talked about the hybrid strategy going forward. Brian Stellbrink, product application specialist, confirmed that “elements of” the new hybrid technology would be migrating into two additional excavators this year, the 374F and 390F and more machines in the years to come.

What “elements of” means is that Cat will use a mix of different hybrid components when and where they make sense for that size class of excavator. These second generation hybrids will be badged “XE.” The XE doesn’t stand for a specific acronym, says Stellbrink. Rather it denotes that the excavators so labeled will have the most advanced hybrid technology and systems for their size and applications.
In other words, these XEs going to be marketed not merely as hybrids, but as Cat’s premium excavators. At the same time Cat is developing a line of “GC” branded excavators which don’t have the high-tech bells and whistles but offer a low cost per hour solution for contractors with lower utilization rates.
Hydraulic hybrid innovation
Unlike all other hybrid systems which store and release excess flywheel power in electrical form, Caterpillar’s hybrid systems are all hydraulic. The company’s suite of hybrid technologies includes three elements (all three of which appeared on the original 336EH and now on the 336F L XE:
1. The Electronic Standardized Programmable Pump or ESP. This is a smart pump, one controlled by a computer interface that is making decisions on input variables from the entire hydraulic system.
2. Hydraulic Hybrid Swing system. This device is a large, piston-style nitrogen gas-over-oil accumulator that lies under the sheet metal horizontally at the back of the machine and absorbs excess swing energy from the rotating superstructure and releases it back to the system when and where needed.
3. Adaptive Control System (ACS) main valve. In a traditional hydraulic system, oil is pressurized, sent to where it is directed. But on the return trip to the hydraulic reservoir, the oil limps along, expending no more energy than it takes to get back home. In Cat’s system if the ESP detects a need for additional pressure or flow anywhere in the system, it tells the ACS valve to redirect the oil to that active function in need of additional hydraulic horsepower. No rest for the weary oil in this system, but that also means very little wasted hydraulic energy either.
With these three elements making hyper-efficient use of the hydraulic system Cat engineers downsized the engine and upsized the hydraulic system. As a result, the company claims a 25 percent boost in energy efficiency for the 336F L XE compared to similar size non-hybrids.
2D upgradeable to 3D
In addition to the advanced hydraulics, the 336F L XE also comes with a standard “smart boom” which includes a 2D grade control system. This measures and controls the exact position of the bucket enabling you to dig a perfect colombia bogota, flat bottom trench at a predetermined depth and slope. The benefits are substantial:
Nobody has to jump in the trench to measure the depth. This improves safety and reduces manpower needs.
Over digging is eliminated so you don’t waste time refilling and recompacting low spots.
You get to grade faster in fewer passes, not having to finesse the last few inches of every foot of the trench.
A 3D system can be added on top of the 2D system without having to remove any of the original 2D components. In addition to grade and slope control, the smart boom also incorporates what the company calls the Cat Production Measurement System, which weighs the load as the boom swings with no interruption in the loading cycle.

Caterpillar Inc. will lay off 475 employees, 300 of them in and around Peoria, where the heavy-equipment manufacturer is headquartered.

A Caterpillar (NYSE: CAT) spokesperson told the Peoria Journal Star that thecompany is restructuring and that “current business conditions” also contributed to the decision to cut jobs. Not all of the layoffs will come at the same time, the spokesperson told the Journal Star, and some employees will be able to continue working for several months.

One employee was quoted in that report saying that a meeting informing workers of the impending job losses implied that those positions would be shifted overseas; Caterpillar did not confirm that. All of those jobs will come from the company’s Customer Services Support division, the report added.

In its report, the Associated Press pointed out that Caterpillar colombia  has cut hundreds of other jobs in recent months. Since the start of this year, the report said, the company has laid off more than 500 people at facilities in East Peoria and Decatur.

Though the company may be moving those particular jobs elsewhere, Caterpillar appears intent on keeping its headquarters in Peoria, where, this February, the company affirmed it would remain while consolidating workers on one campus.
