Volvo’s new 55tonne capacity A60H hauler marks a 50th anniversary
Volvo Construction Equipment’s new 55-tonne capacity Volvo A60H meets growing customer demand for articulated haulers with larger capacities. The articulated hauler concept was originally launched by Volvo in 1966 and celebrates its 50th birthday this year.
The Volvo A60H’s higher payload – a 40% increase on Volvo’s A40 –lowers the cost-per-tonne for hauliers. It also offers an alternative to rigid dump trucks and construction trucks operating on soft, uneven or steep roads, allowing a similar amount of material to be hauled in a shorter cycle time.
Good stability, comfort and high hauling speeds are ensured by the matched drivetrain, automatic drive combinations (including 100% differential locks), all-terrain bogie, hydro-mechanical steering and active suspension.
Volvo builds on the high capacity and hauling speeds of the A60H with intelligent monitoring systems, such as MATRIS, CareTrack. The Volvo On Board Weighing System further optimises production and minimises operational costs. The Volvo Care Cab has a centrally-positioned seat, superior steering, excellent suspension, low noise levels, climate control and ample space and visibility.
Volvo articulated haulers have a high degree of uptime thanks to heavy-duty front and rear frames, hitch and wet disc brakes. Servicing and routine maintenance checks are easier thanks to quick access from a front grill that swings down, opening up a service platform with anti-slip steps and an electric hood that opens to 90°, allowing full and safe access to the engine compartment. In addition to long service intervals and minimal maintenance requirements, Volvo’s popular Customer Service Agreements help customers stay in control of costs.
BHS-Sonthofen’s mixer for the calcium silicate industry
BHS Sonthofen’s new generation of type DKXK twin-shaft batch mixers feature a rubber trough specially designed for producing calcium silicate bricks. Calcium silicate bricks are made of sand mixtures containing a high silicate, quicklime and water content, a highly abrasive material.
BHS has specifically developed the DKXK type of mixer for producing lime mixtures as an alternative version to the proven DKX type of twin-shaft batch mixer. Instead of a steel trough with a lining made of wear tiles, BHS builds its calcium silicate mixer with a rubber mixing trough that pulsates when mixing, thus effectively preventing sticky mixing material from caking.
This reduces blade and trough lining wear as well as reduces the engine’s power consumption.
In the future, BHS-Sonthofen will offer the new mixer for the calcium-silicate brick industry with a filling volume ranging from 1,000-6,500litres.
Ammann new plants are versatile
Ammann says that its latest SolidBatch asphalt plants are designed to combine versatility and reliability. The SolidBatch 140 and SolidBatch 180 offer capacities of 140tonnes/hour and 180tonnes/hour respectively. These units are highly standardised and the base model is offered with a few extra features to expand its range of capabilities. Should customers wish to include RAP within the asphalt mix, this can be handled with the addition of separate units for instance. Customers are able to purchase the standard SolidBatch model and then choose from a variety of options to tailor the unit to the specific needs of each application.
Terex Trucks launches TA400, a new-generation articulated hauler
Terex Trucks has rolled out its flagship 38-tonne TA400 articulated dump truck, the largest and first of the Volvo-owned company’s new generation hauler lineup. Investments have been made to ensure increased durability and protection of truck components, including upgraded hydraulic hoses, electrical interfaces, transmission mountings and brake pipes. To prolong hydraulic component lifecycles, Terex Trucks has introduced magnetic pressure filters that reduce the risk of contaminants entering the system. They also improve the cleanliness of the hydraulic oil.
Force-cooled multi-disc brakes lower operational costs and increase safety. Supported by an electronic activated exhaust brake and a six-stage modulating transmission retarder, the TA400 benefits from longer brake component lifecycles. The transmission now features high-performance oil that extends time between service intervals to 6,000hrs and the powerful drivetrain maintains traction in even the most difficult terrain thanks to longitudinal and limited slip transverse differential locks.
The engine and drivetrain are well matched, using automatic adaptive shifting. A pre-selected two-speed transfer box (drop box), providing good performance and productivity for all haul conditions. The new, generation 10 TA400 introduces the Stage IV compliant series of engines for the European market. The Stage IV system features the latest generation Selective Catalytic Reduction (SCR), combined with Exhaust Gas Regeneration (EGR) technology and a Variable Geometry Turbo (VGT).
Maintaining focus on reducing total cost of ownership Terex Trucks has also removed the need for use of a Diesel Particulate Filter (DPF). Terex Trucks now offers fully compliant, cost-efficient haulers to all global markets, with the new European Stage IV system complimenting Terex Trucks’ Tier 4 Final range of articulated haulers for the North American market and the Tier 2 range designed for the non-regulated markets across the world.
Investments have also been made to enhance operator comfort, ensuring a smooth haul and more productive operation. Anti-vibration mounts for the engine and cabin, as well as cushioned stops on the steering cylinders have been integrated, and the cab features an improved air conditioning and ventilation system.
Machine performance information has also been improved, including transmission diagnostics that informs the operator on the status of the machine, including the oil quality, oil level, filter life, and fault codes/service indication.
Terex Trucks said more new generation articulated haulers will follow later this year and next.
Benninghoven asphalt plant innovations
Benninghoven, now part of the Wirtgen Group, is introducing new recycled asphalt pavement (RAP) developments. Benninghoven says that its counterflow parallel drum system with hot gas generator offers considerable benefits for RAP applications.
The new design ensures that the recycled material is heated in a counterflow cycle, flowing against the heat source in the drum. The design achieves a high material temperature while lowering exhaust gas temperature.
The material no longer has to be run overheated, which cuts energy use. Head of marketing Lars Henrich said, “The burner is installed in a separate hot gas generator.” This process is only possible due to the use of the hot gas generator as direct firing would damage the RAP and make it unusable.
Burner, hot gas generator, dryer drum, separator cover and circulating air system are said to be precisely balanced. Henrich added that the system also produces low CO2 emissions while allowing a much higher percentage of hot RAP in the mix (up to 90%) than with earlier generation plant designs. Also new is the potential for an additional cold RAP circuit for its plants, using a different elevator than for the hot RAP.
DSB launches new Innocrush machine
Austrian manufacturer of mobile crushing and screening machines, DSB Maschinenbau, is introducing a new DSB Innocrush machine. Innocrush 35 machine includes a screenbox IS2
The company’ relaunch of the Innocrush 35 machine includes a screenbox IS2, while the hydraulically opening engine package will be wider. The company’s Innodrive system, the innovative drive concept without a clutch, is now installed as standard in all dsb machines.
“We also found out that the main conveyor belt of the Innocrush 35 will now be longer and steeper, which naturally has a positive effect on the discharge height,” says the company.
“In general the machines will be executed straight-lined and tidy and there will be one or the other new features.”
Dieter Durstmüller, general manager of DSB Maschinenbau in Linz, Austria, says: “We listen carefully when customers report their operations and thereby provide inputs and suggestions on what would be necessary, useful or helpful to the existing valuable features.
“It makes no sense to design a machine on the drawing board: it’s about buliding powerful crushers, which are easy to use and meet exact the customer’s requirements.
“Even with the current development, our focus was clear: functional design, highest output
“An industrial designer was instructed with a design study in order to give the machine a new look. The brief was: simple and clear. The design should not hide, but usefully supplement and summarise clear functional units of design technology.”
Komatsu broadens intelligent dozer range
Komatsu Europe is widening the range of intelligent bulldozers it offers. This new addition to the line-up brings the range of intelligent dozers from Komatsu to five models in all. The new D85EXi/PXi-18 dozer is said to offer all the benefits of the existing D85-18 dozer, with improved efficiency and reduced running costs for customers.
The machine control technologies are integrated into the dozer in the factory so there is no need to fit masts or other external units. With integrated sensors fitted in the machine, the system is also said to be more durable and accurate than retrofitted machine control equipment.
The firm claims that this innovative machine control package allows automated operation from heavy dozing to fine grading. The system senses and controls the blade load, optimises the start of the cut and also minimises track slip, reducing wear and tear. Dozers fitted with this system can deliver greater efficiency in any application, especially when a specific finished level must be guaranteed.
Powered comes from a 197kW, SAA6D125E-7, Tier 4 Final/Stage IV emissions-certified engine with a heavy-duty aftertreatment system. The firm claims that the D85EXi/PXi-18 emits up to 85% less particulate matter and nitrogen oxides (NOx) than the earlier D85EX/PX-15.
Kobelco expands range of Japanese-built Generation 10 excavators
Kobelco’s new 35tonne SK350NLC-10 medium excavator is arriving in Europe this spring. The machine, with a bucket capacity of between 1.2m3 and 1.6m3, is the latest addition to the Japanese manufacturer’s Generation 10 line-up.
The 350 has increased power and greater fuel economy compared with Generation 9 models, said KCME product marketing manager Peter Stuijt. Eco Mode function can reduce fuel efficiency by up to 25%. Other Gen 10 models are the SK210LC-10/SK210NLC-10 and the SK260LC-10/SK260NLC-10.
The Generation 10 models have improved shovel load coupled with dynamic digging force helps contribute to a 7% greater digging volume when compared to previous models in class. All Generation 10 machines are powered by powerful Hino engines, which incorporate DOC (Diesel Oxidation Catalyst) and the combination of DPF (Diesel Particulate Filter) and SCR – Selective Catalyst Reduction. These systems reduce the amount of DEF/AdBlue fluid used in the post-exhaust gas system. Harmful NOx gases have also been reduced by around 88%.
Generation 10 models have revised structural sections, reinforcement points and pin bosses and the attachment point has been reinforced to handle a higher work volume with greater power. Kobelco’s Arm Interflow System (AIS) is a new hydraulic regenerative system that enables the boom to redistribute hydraulic fluid to the shovel arm during operation. This reduces the need of an external pump and results in less engine and hydraulic workload, thereby contributing to even better cost efficiency.
Layout of the upper deck has been “decluttered” and its height has been lowered to provide an increase in overall maintenance space and to enable easier engine access.
Other features include – on key models – a new compact and easily replaceable canister-type hydraulic oil return filter and a new specification air cleaner inner element, while the fuel tank has been relocated to the left side. In terms of safety, the operator can now access machine diagnostics via the multi-display cabin monitor assist, and the washer tank has been re-located inside the cabin, ensuring work continuity.
Generation 10 FOPS II and ROPS-compliant safety cabins include control levers with a lighter-feel, a new ‘lock’ lever, control lever box and revised rear storage tray. Additional air conditioning vents are optimised for improved operator comfort and provide greater comfort in hot climates. The new radio is also USB, AUX and Bluetooth-enabled, increasing operator comfort over long hours of work.
New compact loader developed by SDLG
A key introduction for SDLG is its new L948 wheeled loader. The machine has been developed to meet the needs of customers in emerging markets and features well proven and robust technology. Durable and reliable, the L948 offers a 4tonne bucket capacity. Power comes from a Yanmar SD60B Tier 3/Stage IIIA diesel, which drives though a ZF 4WG158 automatic transmission. The machine benefits from full hydraulic brakes and load-sensing capabilities, plus a large and comfortable cab which includes a reversing camera for safer and more efficient site movements. Maximum breakout force is 125 kN and it has a standard bucket capacity of 2.3 m3.
Efficiency foremost for Hyundai HX235 crawler excavator
Hyundai’s new HX235 LCR short tail crawler excavator, a stage IV generation machine, can load trucks up to 5% faster and levels up to 4% faster than the 9A-Series. To achieve efficient grading, the HX series can apply boom floating control using arm-in and arm-out operation only, allowing stable operation even in high-load work.
The new HX235 LCR shares many innovative features with the South Korean manufacturer’s other new excavators – the HX145 short tail crawler excavator and the company’s first wheeled excavators, also stage IV – HW140 and HW210. These include new safety features such as Hyundai’s exclusive AAVM – Advanced Around View Monitoring – system for 360° virtual operating view which is displayed on the 20cm cluster-monitor. An Intelligent Moving Object Detection system that senses and warns the operator when objects come within working distance of the machine.
HX and HW ranges also have newly designed cabins incorporating a larger front screen. The driver’s door is easier to open from the inside with an additional handrail. The interior of the HX and HW cab offers 13% more space for the operator (compared to 9A-series). The machines are also fitted with Hi-Mate, a remote management system developed by HHIE. Through its satellite powered technology, customers can now enjoy an unmatched level of service and product support. With one press of the button, users are able to remotely evaluate machine performance, access diagnostic information and verify machine locations. It’s even possible to program a virtual ‘geo-fence’ to prevent the machine from leaving a specific area.
Enhanced reliability features on the HX and HW Series include reinforced longer-life pins and bushings coupled with wear-resistant polymer shims. There are newly designed cab shock mounts with dual shock absorption for reduced vibration and noise and improves operator comfort. Serviceability enhancements include ground-level access to the fuel filter and convenient exterior access to the cab air filter.
BBA Pumps launches new line of dewatering pumps
BBA Pumps has launched a new line-up of dewatering pumps. The company says that the main focus went into the reduction of the carbon footprint, with all units standardised on the cleanest highly-regulated diesel engines to comply with stringent European emission legislations.
The pumps are designated BA100K (4” unit); BA180E (8”) and BA300E (12”). The BA100K, driven by single cylinder Hatz with a DPF module, can pump 190m³/hour and has a maximum head of 22mwc (metre water column).
The next in line, the BA180E, can handle 720m³/hour and has a maximum head of 41mwc, while the BA300E’s 1,250m³/hour pumping capacity and maximum head of 19mwc is achieved, as with the BA180E, using a new Perkins 854 four-cylinder Perkins Stage IIIB engine with DPF/DOC after-treatment technology.
“We received frequent requests for a more compact 12” waste water pump, this is because of the limited space available in urban areas for sewer by-pass jobs.” says Henno Schothorst, product manager at BBA Pumps.
“That’s why we are proud of this entirely new BA300E development. Compared to the previous model it is now much easier to deploy for waste water projects.”
New concrete tester from Controls
Controls says it is offering a new system that provides more accurate testing of concrete and cement. The Automax E-Modulus can be used for both the standard failure test and the determination of the Modulus of Elasticity. This modulus is a key parameter to verify the behaviour of building structures under load, such as in seismic areas or for high buildings.
This determination is performed conforming various national Standards as DIN 1048/1, ASTM C469, BS 1881:121, ISO 6784, UNI 6556. The accuracy of the console depends on precise oil flow control by a double stage hydraulic pump. The unit is specifically designed and optimised for this application and powered by a variable speed DC motor with closed loop digital feedback and customised PID algorithm. The oil flow control is furthermore integrated by a Flow-Sharing device to allow loading and unloading cycles. It is compatible with both small capacity frames (for cement and mortar specimens) and high capacity frames for concrete, high strength concrete, blocks and cores.
The firm’s new Automatic digital mortar mixer features a pre-defined procedure according to Standard allowing manual introduction of sand by the top filling hopper. The sample prepared by the automatic mixer can then be tested for the setting time and consistency determination by the recent VICAMATIC2, designed using the latest developments in electronic technology, includes a color touch-screen display and makes possible the creation of a network with up to 32 independent units all controlled by a single PC.
Mecalac unveils its AS 1600 swing loader
Mecalac’s new, four-wheel steered swing loader, the AS 1600, replaces its popular predecessor, the AS 150 that for 13 years was the company’ flagship in the 11-tonne class. The company says the AS 1600 comes in an entirely new design and offers a number of features it has for the first time developed for a loader of this class.
These include a new intuitive operating concept; the new traction drive with MDrive; a new low-emission engine, and the load-sensing hydraulic system with flow sharing and analysis of loader data via the Mecadiag diagnostic system. The wheeled loader reaches a load over height of 3.4m, and with a turning radius of 4.35m across the rear it is ideal for confined work sites, says Mecalac.
The AS 1600 handles larger buckets than its predecessor. Several bucket sizes from 1.6-2.5m³ and several types are available, and the machine can also be used as a rough terrain forklift, excavator, or for lifting. The AS 1600 comes with a water-cooled 90kW Deutz turbo-diesel engine with intercooler that complies with the requirements of EU Stage III B.
Innovative burner cooling for asphalt plant
A highly innovative approach to cooling is a key feature of the asphalt plants developed by Günter Papenburg. Employing patented technology developed originally for liquid-fuelled rockets, the firm’s burners are said to be both highly efficient and effective. Because of the novel cooling jacket design, the coal dust-fuelled burners can reach working temperatures more quickly than rival systems according to the firm, making a significant reduction in the amount of fuel required overall. Günter Papenburg has licensed the cooling technology from Loesche, a German producer of coal milling systems. This innovative cooling concept was originally developed by rocket scientist Werner von Braun for use in rocket motors.
Managing director Carsten Weiss claimed that the firm’s burners are also more efficient and consume more of the fuel than rival types, which only burn 90% of the coal dust. He said, “We get an asphalt temperature of 170°C with low emissions and high efficiency.”
Now being used in a new asphalt plant in Germany for a major producer, the burner technology has been extensively tested according to Weiss. This novel plant features a counterflow drum and can handle a high percentage of RAP to produce a high quality mix. Weiss said that research carried out by Aachen University analysed the thermodynamic performance of the plant and shows the efficiency of the technology now being used by Günter Papenburg.
This plant also benefits from a sophisticated computer control package, with new software allowing the producer to use different grades and quantities of RAP in the mix, while delivering high quality product. The computer can accurately adjust the position of the flights inside the plant so as to control gas flow and optimise operating temperatures. The plant also has a design which specially configured piping, which minimise the build-up of materials inside and reduces the risk of blockages or waste.
Kubota offering alternative fuel options
Kubota says it is offering a range of engines that can run on various alternative fuels. These can be used instead of diesel fuel engines. As an alternative to diesel, the machinery manufacturer has the choice between power units with similar dimensions (footprint) fuelled by petrol (gasoline), natural gas, liquefied petroleum gas (LPG) or compressed natural gas (CNG). These alternative fuel type engines are likely to be cheaper to buy and run than future diesel engines. To lower emissions future diesels will require costly exhaust gas after-treatment. However, many of the alternative fuels such as CNG or LPG have far lower emissions levels and do not require the complex after treatment technology as a result.
Ecomeca develops new line of crusher buckets
Ecomeca from Finland says it has developed a new innovation in the field of crusher buckets that increases productivity. The company has different models available for excavators from 18-50tonnes, including models that can be installed on wheeled loaders.
It is highlighting its Ecomeca 145 model, which can be installed onto 28-40tonne excavators. “The concept Ecomeca has developed is backed up by several patents and patent applications in more than 40 countries,” says the company.
“The Ecomeca product is different from existing crusher buckets. It contains one or two rotating drums. The construction is a combination of screening and crushing.” The open drum construction makes screening possible, and the easily changeable hammer bits crush the materials.
“With Ecomeca, even rebar is not a problem, and by reversing the drum(s), it clears itself. The drums crush the material down to 50-150mm, depending on the setting.” Ecomeca says its technology allows crushing of dry, wet and sticky materials, while impurities and size variations do not hinder the crushing process. The crusher incorporates built in fail-safes (a hydraulic valve and an overload clutch) to prevent breakage.
World launch for new wear parts system from Combi Wear Parts
Combi Wear Parts’ C-REX is a new wear parts system developed for excavators weighing 12-45tonnes and wheeled loaders weighing 12-55tonnes. “Even though the Combi parts system is also aimed for the construction segment, there is a lot of difference between C-REX and Combi parts. When we designed C-REX we kept the best features from Combi parts but we made some big improvements as well. For example we have developed a mechanical lock that makes mounting and dismounting teeth so much easier. The lock is hammerless and has just one loose part (the locking pin) that can be re-used throughout the life of the system,” says Sacha de Bilderling, sales manager at Combi Wear Parts.
Wechselberger says: The C stands for construction. REX is a direct link to the dinosaur-era giant Tyrannosaurus Rex (T-Rex) who had “unequalled strength, extreme power and a razor-sharp bite.”
On C-REX, the teeth are longer and have been designed with a larger portion of wear material compared with the Combi parts system that was well known for good performance. The new C-REX adapters are also less sensitive to wear, which means users will get longer operation time from the adapter, thus saving costs for both production and maintenance.
