Kubota Introduces M7 Generation 2 Tractor

Kubota Tractor Corporation showed off its new M7 Generation 2 deluxe tractor at the National Farm Machinery Show in Louisville, Kentucky.

“It’s got all of the simplicity and controls of our standard tractor, but now we’ve added a tractor with the Closed Center Load Sensing hydraulics,” said Kent Brown, senior product manager. “So, for farmers that have a value conscious need for a tractor but want a high performing hydraulic system, this tractor is going to be built for those customers.”

Brown said the front end loader on the M7 Gen 2 tractor is best in class. It’s good for baling hay, but this tractor can also pull a smaller planter or sprayer. Other improvements include a new semi-powershift transmission and an exceptionally clean diesel engine.

Anglo Quellaveco to operate Cat fleet teaming 794AC trucks with both rope & hydraulic shovels

By the time Anglo American produces its first copper from the Quellaveco mine in Peru, the company will have owned the orebody for nearly 30 years, spent more than 15 years laying the groundwork, invested millions of dollars, and made thousands of decisions necessary to get the mine up and running. Company leaders believe that this attention to detail and commitment to preparation will allow the mine not only to succeed but to exceed expectations. In fact, before the first copper ore is extracted from the mine, the company is already thinking ahead.

“We see significant potential to expand Quellaveco beyond its current 30-year reserve life as well as to increase throughput above the initial capacity of 127,500 t per day,” says Anglo American Chief Executive Mark Cutifani. First production of copper is expected in 2022, ramping up to full production in 2023. During the first 10 years of full production Quellaveco is expected to produce approximately 300,000 t per year.

“While Peru will be a new operating geography for us, we’ve been preparing the ground for many years — both literally and figuratively — developing strong relationships with local communities, government authorities and regulators along the way,” the company says on its website. Anglo American board members approved development of the project in July 2018. That same month, partner Mitsubishi Corporation increased its interest in the project to 40%. The company has secured the licenses and permits to move forward with Quellaveco and development has commenced. “After several years of extensive preparatory work, we are very pleased to develop the project together with our partner Mitsubishi,” said Cutifani.

Roadtec boosts power on cold planer and milling machine

Roadtec has equipped its RX-700 cold planer and its RX-900 milling machine with new engine options.

The new model of Roadtec’s RX-700 features the increased power of an 800 hp Tier 4 Final Caterpillar engine.

The new Tier 4 Final engine does not require diesel exhaust fluid as a component of the after-treatment system, which reduces operating costs typically required at this emission standard.

Thanks to the increase in power, the updated half-lane cold planer provides higher production and reliability.

“The increased horsepower delivers even more production. We give customers what they need: a reliable and efficient cold planer that helps them complete jobs on time and with success,” said Kyle Hammon, Roadtec’s product manager for mills, stabilizers and brooms.

The RX-700 cuts up to 35 cm deep with standard widths of 2, 2.2, 2.5 and 3.2 metres.

As well, the cutter housing includes angled moldboards, which prevent material from accumulating around the drum, resulting in less wear. Furthermore, track pads are bolted on, which makes changing pads fast, saving time and money.

To achieve a stronger and lighter frame, Roadtec used A656 Grade 80 steel when building the RX 700, which is twice as strong as common mild steel.

A 60-degree conveyor swing, which is greater than the traditional 40-degree swing, allows easy feeding of a truck in an adjacent lane or around a tight bend. A folding secondary conveyor is also available to aid in transport and loading.

Automated elevation controls
The Automated Control of Elevation (ACE) system automates machine elevation through a combination of grade and slope sensors. The operator and ground crew may easily make changes to the grade and slope parameters, on the job and in real time.

Roadtec RX-900
Roadtec’s RX-900e asphalt milling machine has been upgraded to a 1,055 hp Tier 4 Final Caterpillar engine. The new Tier 4 Final engine does not require diesel exhaust fluid as a component of the after-treatment system, reducing the operation costs typically required. The upgraded power and heavy-duty fabrication make the RX-900 ideal for half-lane and full-lane milling.

Alleviating Firing System Safety Risks And Costs

The need to streamline perforating operations while alleviating the risk of misfires, assembly and downhole time, labor and maintenance costs is a key component to hydraulic fracturing operations, particularly when completing long horizontal wellbores in unconventional shale plays. DynaEnergetics’ DynaStage perforating system incorporates technology in the addressable firing system and an improved mechanical design to help improve overall plug-andperf (PNP) operations. It optimizes perforating operations with fully assembled and ready-to-shoot gun modules delivered to the base or well site.

The fully disposable, maintenance-free system is made more robust by eliminating traditional approaches to selective perforating, detonators, gun hardware and accessory equipment and, with its additional safety features, allows other wellsite operations to run in conjunction with the perforation process.

System features

The system includes intrinsically safe, integrated switch-detonators, preassembled guns with shaped charges and a composite plug, a firing panel, and a surface tester. Commercialized in 2016, the DynaStage system has targeted two areas to improve efficiency and reduce costs.

The first is safety, for which the system has a simple design that eliminates the risk of inadvertent detonation from stray current or voltage. Surface explosive handling and arming can be conducted in less time and in conjunction with other operations. The design eliminates the need to hold the gun system at shallow subsurface depth during simultaneous operations. Both factors reduce wait times at the well site.

The second targeted area is reliability. The design of the electronic system and simplification of the mechanical field assembly process help to reduce the number of misruns, which increases efficiency and lowers the cost of completions.

Improved assembly at surface

During the assembly of conventional perforating systems, including mechanical component assembly, arming the system and connecting the gun string to the wireline, there is a risk that resistorized detonators can be initiated with radio frequency energy, stray current or stray voltage on the surface. These traditional detonators can contribute to an increased risk of injury and destruction when connecting the detonator to the gun string and wireline truck.

Improve your haul cycles

Haul road design, construction, and maintenance have a huge impact on truck haulage cycle efficiency, costs, and production. Design factors, including road materials, grades, curve designs, and traffic layout, play critical rolls in efficient truck haulage. But proper maintenance of roads — to ensure smooth surface conditions, low rolling resistance, and consistent grades — is equally important to achieving lowest cost per ton of material hauled.

As an example of the importance of haul road design and maintenance, a 5-percent increase in rolling resistance can result in as much as a 10-percent decrease in production and 35-percent increase in production cost. Though 5-percent rolling resistance doesn’t sound like much, it is equivalent to about 2 inches of tire penetration.

Good haul road design, construction, and maintenance reduce fuel burn, help minimize tire heating and damage, and reduce wear on truck components. The results are lower operating and maintenance costs and less downtime.

Motor graders play critical role

Motor graders are not only critical to maintaining haul roads, but also to building haul roads to the right specifications, which, in turn, enables the roads to resist damage and provide optimum hauling conditions for longer periods.

Motor graders are the best grading machines for ensuring that cross slopes and cross falls are built to specifications. Building to spec helps ensure that roads drain water efficiently, which reduces the formation of potholes and washboards, and reduces the need for frequent haul road maintenance.

Motor graders are also the best machines for building superelevated curves. Such curves help trucks maintain proper weight distribution and constant speed, reducing the frequency of transmission gear shifts and braking for less wear on truck components.

After roads are built, the motor grader is the most efficient tool to keep them in good condition. Motor graders provide smooth roads, constant grades, and reduced rolling resistance. They also can maintain safety berms and drainage ditches, and, with their fast travel speeds, graders can be dispatched to quickly clean up rock spillage from haul trucks.

Caterpillar introduces Next Gen excavators and more new equipment

Caterpillar introduces the Next Gen 336 and 336 GC excavators, designed to balance productivity with lower fuel consumption and maintenance costs. Integrated Cat Connect Technology is said to increase operating efficiency by up to 45 percent over traditional grading operations. The standard Cat Grade with 2D system provides guidance for depth, slope, and horizontal distance to grade through the standard touchscreen monitor. Standard Grade Assist automates boom, stick, and bucket movements so operators can stay on grade with single-lever digging. Cat Payload precision makes loading more efficient, while an E-fence feature prevents the machine from moving outside operator-defined set points. The 336 is up to 15 percent more fuel efficient than the machine it replaces. With extended and more synchronized service intervals, the excavators can also lower maintenance costs by 15 percent over prior models; for example, the new air filter has double the dust-holding capacity over the earlier design. Three cab packages are available to keep operators comfortable. All include standard features such as keyless push-button start and touchscreen monitor.

Matching Seals to Dynamic Sealing Applications

Successful sealing of fluid power cylinders requires a delicate balance of interrelated factors that affect the sealing process in a dynamic system. These factors include lubrication and mating surfaces; design factors, such as shape, material, and process; and environmental factors, such as pressure, temperature, time, dynamics, and assembly.

Understanding the role of lubrication is the first key to successful sealing in dynamic systems. A fully lubricated system will experience some leakage, usually in the form of a fluid film, but friction will decrease, leading to a corresponding decrease in seal wear. Not surprisingly, the opposite is true: In a sparsely lubricated system, the fluid film decreases, but friction—and thus, wear—increase.

Moreover, sealing tends to improve as fluid pressures increase. Because system pressure on the seal surface compresses the seal axially, the seal is forced more tightly into the gland, improving conformability of the seal with the metal surfaces around it. If the seal is correctly designed, as system pressure increases, sealing force and effectiveness also increase.

A seal’s ability to resist extrusion is a third key factor. Seals in dynamic systems must resist shear forces resulting from the differential between the pressurized and unpressurized sides of the seal. Shear forces tend to push the seal into the gap between adjacent metal surfaces (known as the clearance gap), and the seal material and profile must be sufficiently strong and stiff to resist being damaged or destroyed.

Rod Sealing
Leak-free performance and high service life cannot be ensured by a single sealing element in heavy-duty applications. Because the cylinder’s piston rod is directly exposed to the environment, it’s paramount that the seals keep the fluid in the system. External leakage is easily noticed. Not surprisingly, then, it has become a common criticism of hydraulic power transmission.

GOMACO to Unveil GT-3600 Curb, Gutter Machine at World of Concrete

GOMACO’s new Xtreme GT-3600 curb and gutter machine will be displayed for the first time ever in GOMACO’s booth in the Central Hall at World of Concrete 2019. The GT-3600 was the first three-track machine to slipform a 24-in. radius, and now, with the Xtreme package on board, tight-radius paving is easier and more efficient than ever before. The Xtreme package adds G+ radius software with slew drives, smart-sensored hydraulics and intelligence to the GOMACO GT-3600.

Xtreme steering and ultimate intelligence have been added to each of the GT-3600’s three tracks and include rotary-sensored slew drives, sensored All-Track Steering and All-Track Positioning, and smart hydraulic cylinders. The Xtreme GT-3600’s tracks can now rotate farther than ever before. The smart cylinders allow the G+ control system to know the exact position of all three tracks so it can make steering adjustments as needed. It’s the ultimate in finite and accurate machine control.

The first three-track slipform curb and gutter machine to slipform a 24 in. radius now features GOMACO’s Xtreme Radius program for tight radii on stringline. The G+ radius software allows the operator to program the size of the radius into the controller.

G+ calibrates and manages all the aspects of traveling around the radius, including track angles and individual variable track speeds. As the Xtreme GT-3600 approaches the radius, with the values already dialed in, the operator activates the radius program, and the machine slipforms around the radius. It’s that easy for any operator to pour a curb and gutter radius. The individual track speed control provides smooth machine travel around the radius. The G+ control system also easily interfaces with any of the major 3D guidance systems for the same smooth control.

A smart hydraulic cylinder also is utilized for intelligent offset when telescoping and sideshifting the mold mounting system. The smart cylinders provide G+ the ability of repeatable mold offset. The trimmerhead and mold also have independent vertical adjustments for raising and lowering to work around job-site challenges.

The Xtreme GT-3600 is equipped with the latest in Tier IV technology. Along with Tier IV is a new optimized cooling package with a hydraulic fan controlled by G+. G+ adapts the cooling needs to individual jobsite conditions for a quiet and efficient operation. Fuel efficiency also has been optimized and combined with an increased fuel capacity for an uninterrupted day of paving. The Xtreme GT-3600 also is available with GOMACO Remote Diagnostics (GRD) for machine troubleshooting, diagnostic reviews, software updates, and more.
