Keestrack is targeting 30% growth a year over the next five years in its North American business. The Belgian sustainability-minded crushing and screening plant manufacturer had a strong presence at CONEXPO/CON-AGG 2023, showcasing its diesel-hydraulic, diesel-electric hybrid, and zero (no onboard engine) plant range. Displayed solutions included the B7H jaw crusher, a heavy-duty machine for mining and quarrying customers, the R3h mobile impact crusher, the H4 cone crusher, the R5e hybrid impact crusher, and the W4 dust suppression cannon. Keestrack’s first electric plant solution was launched in 2006, and the company has established an impressive reputation as a sustainability pioneer. Management sees mineral materials processing decarbonisation as one of its core goals.

The new product is installed inside conveyor belt transfer point skirtboards to absorb impact and abrasion, and to create a dam to shield the sealing system from the weight of the of the material load, prolonging the life of the seal.

Seth Mercer, marketing manager at Martin Engineering, said the main markets for the product are in aggregates and mining. “It is geared strongly towards aggregates – dealing with large diameter materials that are heavy and abrasive,” Mercer added.

“We have 19 business units worldwide. Cement is a huge business for us and any raw material extraction. We are seeing a lot of potential growth for our products in Africa. We have an office in South Africa and are expanding in the region.”

The report has been produced for Trimble by Michael Granruth and he said that the technology has highlighted a number of benefits. “A lot of products are focused on productivity. We created a study to manage the overlap in horizontal steering. Typically, there’s around 30% more overlap with manual steering.”

He continued, “What we saw was a 26% saving in fuel, in addition to production savings. If you’re doing the same work in less time, you’re achieving better efficiency.”

He said that for the tests, two operators were selected at random to compare the manual steering with the autosteer function and to gather the relevant data. However, Trimble says that since the study has been released, it has had feedback from customers that the estimate of 30% more overlap using manual steering is conservative and that it can actually reach 50% in many instances.

For the contractor, the package helps ensure an inexperienced operator can achieve the same working quality as someone with many operating hours. In addition, the system can help reduce running costs by lowering fuel consumption and issues such as tyre wear or general service needs for equipment. Trimble says that the system can even allow its clients to meet sustainability targets. Granruth said, “Technology like this autosteering solution is something contractors can use on existing fleets and achieve sustainability gains.”

JLG, part of the Oshkosh Corporation, said the Hinowa deal enables the company to strengthen its range of specialty applications and increase its presence in niche industries, including the agricultural, landscaping, and vegetation management sectors.

At the moment, Hinowa will remain a separate brand and go on marketing its stable of track-based aerial work platforms, mini dumpers, lift trucks, and undercarriage products.

JLG-branded compact crawler booms, which Hinowa has produced since 2010, can be powered by electric, hybrid, and diesel power units.

“The acquisition was all about growing the company and growing our capabilities,” said Frank Nerenhausen, president of JLG.

“JLG and Hinowa are both strong brands. Joining forces allows us to unlock more potential globally. This is a very positive time for the business.”

JLG Industries’ product portfolio includes JLG aerial work platforms, JLG and SkyTrak telehandlers, rotary telehandlers, and a wide range of associated accessories.

The eLION platform is described as an advanced, high-voltage portfolio that includes a full range of modular systems for the electrification of mobile machinery, including motor-generators, inverters, gearboxes, software and accessories.

Developed for the challenging off-highway environment, the portfolio is scalable and supports driving and work functions in a power range from 20 kW to 200 kW (peak power up to 400 kW), for applications in both compact and heavy machines.

The eLION motor-generators and inverters are rugged, robust systems that comply with the IP6K9K ingress protection requirements, says the company, and are engineered to operate across demanding temperature ranges from -40 °C to 85 °C.  The shock and vibration resistance of the eLION components is up to 50 g for shock and 10 g for vibration.

Bosch Rexroth also announced that it has acquired HydraForce, which focuses on mechanical and electrical cartridge valves and hydraulic integrated circuits (HIC). The acquisition allows Bosch Rexroth to offer a wider range of compact hydraulic components and systems, the company said.

Among the Italian company’s current new models are the 1.33C mini backhoe loader, with its compact dimensions helping to expand lateral visibility, and the 8.63TL wheeled loader with telescopic arm, whose hydraulic system is said to follow Venieri’s philosophy of robustness, dynamism and controllability.  

The company’s comprehensive machine range also includes the novel multi-functional articulated backhoe loader, the VF8.23G and VF10.23E, powered by Bosch-Rexroth hydrostatic transmission and a Deutz engine Tier 4F ready for the US market.

Based in Lugo, Emilia-Romagna, Venieri plans to keep growing in its small/middle-size equipment offering, supplying heavy-duty products powered by the best available components offered by the premium market. The company says its product range also offers customers high productivity, high flexibility and strong performance, along with very competitive TCO (total cost of ownership).

The ALLU Veloci is designed for compact-size excavators, loaders, telehandlers, tractors, and skid steers.

The bucket's screening stars are made from polyurethane material, which allows the material to fall through without crushing or shredding material. Large material and debris is left in the bucket while separated from reusable material. This feature is especially handy with composting, when the vegetation is left in the bucket and separated from the reusable material rather than being shredded into the end product.

Finland-based ALLU says the Veloci's screening stars create a rotating motion inside the bucket, screening and mixing the material, producing a quality end-product for use.

The Veloci series is available in five size models for a variety of screening, mixing, and aerating applications. All models are equipped with hydraulic motors for maximum processing power. The drum amount dictates the amount of hydraulic motors used. The Veloci has a double-skin floor, making it robust and durable even when coping with demanding environments and materials.

Its main application areas are landscaping, utility contracting, recycling plants, plus plant hire & rental.

The ALLU D series variable drum enables fixed TS blades to be quickly replaced, with no need to open the chain-box when blades are changed. Enabling a variable drum set-up means an individual drum or blades can be changed more quickly, saving time and money.

ALLU’s patented TS (top screen) construction and screening blades make it possible to screen materials, even when they are wet or moist, without fear of clogging. With the TS structure, it is also possible to get three different fragment sizes from the same ALLU unit by rearranging the screening combs with no additional costs.

Jeroen Hinnen, ALLU global sales director, commented, "ALLU is growing in North America, and we are delighted to be introducing the new Veloci and VD drums. This will strengthen our support to our customers and our operational presence."

Rich Humphrey of Bentley Systems commented that with the continued expansion of the use of general construction management software and 3D and 4D twins, there is a growing need for assistance in using this technology. He said, “This is why we’ve partnered with WSB, to facilitate the digital delivery for owners or DOTs in North America.”

Andy Kaiyala is vice-president of Construction Technology & Controls at WSB and commented, “The market needs somebody to show the industry how to use it. For a lot of contractors, it still seems a challenge. WSB can assist firms in using digital twins.”

WSB can also supply expertise to help clients with developing project models. According to Kaiyala, this allows discussions with customers on how to work through from the bidding process to delivery. The model can be used to simulate what is wanted from a project and allows more time to avoid errors. Design changes are also far easier to implement than using conventional methods. For the customer, being able to show a model to those involved in a project provides greater confidence.

The use of SYNCHRO also means that the various members of the project team will not be working in separate silos as the data is all in the cloud, allowing collaboration in real time. Humphrey said, “It’s about monitoring a project and keeping it under control.”

With the combination of sophisticated software, expertise, and innovation, Bentley and WSB say this digital construction management initiative will help shape the way infrastructure projects are delivered. A single source of truth can connect project, contract, and document management to the future of design, a constructable model, as well as the ability to generate constructable models from current 2D plan sets.

Looking ahead, Humphrey commented, “We need a step function change. Infrastructure needs to move ahead with the times.”

The CONEXPO-CON/AGG 2023 exhibition in Las Vegas has been bigger and better than ever before as the North American construction and aggregates sector embraces the green revolution and the federal government invests heavily in the nation’s infrastructure.

The show was full of great new ideas for driving down emissions, finding new power platforms, and improving the industry’s productivity, profitability, and safety levels.

Join World Highways editor Mike Woof and Aggregates Business editor Guy Woodford as they take a few minutes out of their busy schedule to talk through some of the key trends.

The expansion of the recycling market is very exciting, says Guy, not least because it is providing new revenue streams, creating better sustainability outputs, and helping contractors win new projects.

It’s what the customer wants and expects. Turning dirt into dollars with the lowest possible carbon footprint is definitely the way it’s going.

“And it’s right way to go,” say our expert editors, “for the market, for growth, and for the planet.”  

Contino said that while many firms use Topcon machine control tools on large items of construction equipment, there has been a pent-up demand for simpler units to use on compact machines.

The company is therefore now offering its MC-Mobile system to meet the needs of users of compact equipment, many of which are much smaller contractors. The system has been tailored for use with customers such as owner-operators. Contino said, “A lot of these companies don’t even have an office. Their office is the cab of their truck.” He continued, “We’ve taken machine control and entered into the compact machine space.”

A laser can be used to take points onsite, a task taking 25-30 minutes, and the customer can then use the data to build a model using a tablet device. The same tablet then can be mounted on the item of compact equipment for the operator to follow the design. A GNSS capable option is also being made available for the MC-Mobile product offering.

“We initially built MC-Mobile with the smaller or mid-size contractor in mind,” said Murray Lodge, executive vice-president and general manager, Topcon. “Working with a prism pole and our 3D robotic instrument, the LN-150, users easily measure, design and build right on-site, expanding their capabilities. Now, this new GNSS option allows fleet managers to easily integrate compact machines into much larger, more complex, workflows. Both the local positioning system (LPS) and GNSS versions are made possible thanks to the MC-X platform.”

Employing the latest data management techniques, the Carmix Plus app provides “access to a wealth of exclusive content,” says the Italian company. The app can be downloaded from the App Store and is also available on Google Play.

The new platform presents the entire world of Carmix from a new perspective and lets users “photograph” tags that can be downloaded from the app - or the website - via a smartphone to gain access to reserved digital content.

Augmented reality offers the chance to participate in the Carmix experience through 3D projections of machinery, to interact with the company’s electronic weighing system Concrete-Mate, or to watch detailed videos simply by photographing tags.

Carmix Plus offers information on ‘Smart Mix-Design’ control, geolocation, engine diagnostics and much more.

The company said it is just like being on a real construction site and watching mobile plants at works … all in the palm of  your hand.

Extensive sensor technology, including cameras, records and evaluates the REMAX 600’s feed material as well as intermediate and end products. In real-time, those values reach centralised digital labs at SBM, where they are further analysed. Necessary adjustments are then made on the ‘digital twin’ of the working machine and re-transmitted directly to the REMAX 600 in the field.

Known as ‘Crusher 4.0’ and developed together with the University of Leoben, the REMAX 600 was presented at the bauma Munich exhibition in October 2022. Large-scale field tests of a REMAX 600 are currently being carried out at an Austrian quarry partner.

“We have made three REMAX 600 plants so far. The first has already done 1500 hours of testing with an Austrian quarry customer. All has been good so far on testing,” said Erwin Schneller, SBM managing director. “The first sold machine will be delivered to a customer this year, with the others being delivered by mid next year.”

Another big machine for SBM is the JAWMAX 400 jaw crusher, said to feature one of the most advanced diesel-electric drive concepts on the market. A combination of a fuel-efficient onboard diesel and a performance-tuned generator powers the plant’s materials processing.

SBM’s mobile plant range comprises 12 track-mounted JAWMAX jaw crushers and REMAX impact crushers, capable of 250 – 800tph production. The plant range shares the same innovative drive concept, with fewer hydraulics ensuring less risk of failure, lower maintenance and parts inventory costs, and thus higher availability, says SBM. Overall savings from running the plants can, says the OEM, be 40% to 75%.

SBM sees the US as a major growth market. Schneller said very good discussions are taking place with a number of potential dealer partners in different parts of America. “I think there is the potential for us to sell 50 machines a year in the US,” he added.

Outset, based in Vicenza in the north of Italy, says the module is suitable for use in articulated lorries, wheeled loaders, excavators, and aggregates dumper trucks.

All weighing and TPMS (tyre pressure monitoring system) data can be transmitted via a serial line to the on-board computer or directly in-cloud on external devices, helping users maintain the control and management of productivity, in addition to the safety of their vehicle fleet.

The data can be transmitted via GPS, SIM card or Wi-Fi to the cloud platform, with printed reports to ensure the continuous updating and management of the loading process and tyre monitoring activity.

Luca Toneatti, export area executive at Outset, says the company has more than twenty years' experience in on-board weighing. It supplies TPMS devices for commercial vehicles, earthmoving machines, mining, and logistic vehicles.

Outset technology is designed to provide precise and efficient weighing while loading, in addition to continuous monitoring of tyre pressure and temperature.

Toneatti says that Outset and makes constant, significant investments in R&D to improve its products and develop new, innovative instruments that incorporate the best new technology. The company also works hard, he says, to maintain its reputation for developing user-friendly tech.

The company has an extensive network of authorised sales partners around the world, and plans to expand its network further in the coming years.

Outset provides a range of technologically advanced devices compliant with Industry 4.0 directives, and it works closely with operators to optimise loads. The company’s systems ensure that payloads stay within legal limits and that vehicles do not get overloaded.

“There are many efforts underway to harden the grid,” said Kayla Breja, senior brand manager at Vermeer. “That includes burying the wires – but there are other applications, too.” Among them: laying pipe and water lines.

“This new drill is designed to meet the needs of utility contractors performing large-diameter city work, as well as pipeliners that are performing long, large-diameter bores,” said Tod Michael, product manager of trenchless products for Vermeer.

The 310kW revamped drill is more versatile than its predecessor. “The combination of the D220x500 S3 drill’s class-leading rotary torque and fluid pressure delivers optimised drilling and reaming performance in challenging ground conditions like rock,” Michael adds.

More torque helps reduce the number of passes crews need to make when widening a hole, says Vermeer. High fluid flow helps protect tooling while maintaining drill hole integrity and operational efficiency.
