Hyundai Construction Equipment to enter the ADT market with 30- and 45-t models

Hyundai Construction Equipment (HCE) is set to display 23 machines at bauma 2022 in Munich, in October, with some of the key highlights being a new ADT and a concept hydrogen vehicle.

The company’s stand is 30% larger than in previous years, representing the ongoing growth journey it is on.

HCE’s stand will reveal Hyundai’s position as a technology leader, with a clear roadmap to a cleaner, safer and more productive construction site, whatever the industry sector, it said.

The entry of the company into the articulated dump truck (ADT) market involves the launch of two models, using proven, innovative design and technology to deliver high productivity and superior mobility on site, the company says.

Aimed at the 30-t and 45-t sectors, the HA30A and HA45A are built around a full-time six-wheel drive concept, with front and rear limited slip differentials and a longitudinal differential than can be manually locked, for maximum drive and traction on difficult terrain.

The two ADTs are the first visible sign of the new cooperation between Hyundai Construction Equipment Europe (HCEE) and Hyundai Doosan Infracore (HDI), since the purchase of the Doosan business last year by Hyundai Heavy Industries Group.

The HW155H concept wheeled excavator, powered by a hydrogen fuel cell, meanwhile, features a 14-t payload that can offer eight hours of operation with a 20-minute refuelling time, according to the company. It is based on proven hydrogen commercial vehicle technology, according to the company, with the only emission from the machine being water.

The trucks have a compact chassis design to aid manoeuvrability, with a sloping rear frame and a front-mounted differential integrated into the ZF transmission, allowing for a shorter front frame section.

This, the company says, results in the smallest turning radius in the sector and outstanding stability.

Self-levelling hydro-gas suspension on the front axle further supports a comfortable ride, delivering maximum tractability in tough ground conditions, it said. The turning ring is mounted in front of the chassis articulation point, resulting in an equal weight distribution to the front wheels in all driving situations for increased stability and traction.

Having equal weight distribution allows the operator to use the limited slip differentials with just a 45° locking value, maintaining drive to both front wheels even when steering. The two rear axles employ a tandem bogie drive design, with a single central differential and twin internal gear drives on each side of the truck. These tandem reduction gearboxes rotate in total by almost 40°, allowing maximum oscillation of the rear axles to maintain ground contact on rough terrain, the company said. The single central differential increases ground clearance beneath the truck.

The HA30A and HA45A are equipped with a full hydraulic retarder, combined with an electronic engine brake as standard. This supports the oil-cooled wet disc brakes to achieve an extended service lifetime of up to 15,000 hours. A hydraulically-activated mechanical parking brake, meanwhile, holds the machine when stationary.

The trucks are supplied with a gradient meter, with flip-over protection and a Body Over Centre of Gravity function, to assist drivers when tipping and operating on rough terrain. The sloping rear chassis section evenly spreads the load between the front and rear axles.

The HA30A has a 16.8 cu.m heaped body capacity that rises to 17.8 cu.m with a tailgate fitted. The larger HA45A offers a 24.4 cu.m heaped capacity, rising to 26 cu.m with a tailgate.

Both dump bodies can be optionally heated by the engine exhaust gases to prevent freezing and sticking of materials when operating in colder temperatures. Internal wear plates are available as an option for hard rock use.

Hyundai has employed powerful EU Stage V-compliant Scania diesel engines to power both trucks. The HA30A uses a five-cylinder, 9.3-litre, DC9 turbocharged diesel, developing 276 kW and 1,876 Nm of torque. The larger HA45A employs a six-cylinder, 12.7-litre DC13 diesel engine, producing a maximum 368 kW and 2,476 Nm of torque. Both engines drive through eight-speed ZF automatic transmissions, with integrated retarders.

The torque converter has lock-up in all gears, reducing fuel consumption and increasing efficiency. Fuel, AdBlue diesel engine exhaust fluid and a standard auto-lube greasing system can all be easily accessed from ground level, for improved site safety. The engine canopy tilts forward for access to filters and fill points, while the complete cab structure can also be tilted towards the rear of the truck to provide access for repair and maintenance.

Hyundai’s Himate telematic monitoring system is standard, with satellite and GSM connectivity, to reach the most inaccessible construction and mining sites across the world. This allows customers to remotely monitor productivity, fuel consumption, system warning and maintenance status, reducing unplanned downtime and improving fleet utilisation.

With the most spacious ROPS/FOPS cab on the market, the Hyundai ADT features an ergonomic layout to the controls, which are easily reached from the high-quality air-suspended operator’s seat.

There is plenty of storage around the cab interior, with room for an optional cool/hot box and 12 V power sockets for operator phones and other accessories. Full cab climate control is standard on both models and the cab boasts an internal sound level of just 72 dB(A) for maximum comfort throughout the working day, the company says.

The sloping bonnet provides an excellent view to the front of the truck and there are sliding side windows with hand rails to the side of the seat. A comprehensive monitor panel provides an integrated payload meter, to prevent overloading and to record productivity. Diagnostic functions are included within the monitoring system and the operator can remotely check hydraulic and transmission oil levels from the cab.

A gradient metre ensures that the truck is driven safely within its limits, while an integrated rear-view camera and large mirrors provide excellent all-round visibility, when reversing under an excavator or into the tipping area, the company claims.

The Hyundai HA30A and HA45A articulated dump trucks provide an ideal excavating partner for a wide range of crawler excavators and wheeled loading shovels, according to the company. Designed primarily for major earthmoving and muck shifting projects, highways construction and mine and quarry operations, Hyundai’s articulated haulers provide maximum drive and traction in the worst site conditions, maintaining all-year round productivity for the customer, it says.

XCMG showcases three new US-tailored mining machines at MINExpo 2021

XCMG has brought three new customised products to MINExpo 2021 in Las Vegas, namely its XE950G excavator, XDA45U articulated dump truck and GR3505T5 grader.

This is XCMG’s first time exhibiting at MINExpo, with the company using this time to highlight three new products customised specifically for the US market that are adapted to work under different and highly challenging construction conditions, it says.

The 95 ton (86 t) XE950G excavator is, XCMG says, an efficient and energy-saving model applicable to global markets, featuring an advanced control system and behaviour monitoring system, highlighting dual-pump independent technology. It also excels in comfortable and smart operation and is well suited to extreme mining environments, the company says.

The 45 ton (41 t) XDA45U ADT adopts mature power matching technology and delivers strong passing and reliable braking performance. It is also equipped with precise hydraulic control and is all-terrain adaptive, according to the company.

The GR3505T5 grader has strong traction output and features a high-pressure, high-displacement and load-sensitive hydraulic system. The all-gear rear axle can prevent wear effectively and the hydraulic lock is “error preventive”, XCMG says. The model also provides an upgraded operation experience with speed-sensitive and assisted steering, ergonomic electronic double joystick control system and fresh air circulation with standard cab pressurisation.

XCMG was the earliest manufacturer in the Chinese construction machinery industry to enter the US market and has not only launched products that meet local certification and standards, but also established a comprehensive sales and service network capable of providing complete construction solutions for customers, it says.

Xie Bin, CEO of XCMG North America Corp, says: “XCMG has accumulated a wealth of experience in mining equipment and solutions and is committed to providing highly reliable, efficient and safe products for our customers, and our customisation strategy has enabled XCMG to compete with the world’s best manufacturers in the high-end market.”

Bell ADTs benefitting from EU Stage V MTU Engines from Rolls-Royce

Bell Equipment, the articulated dump truck (ADT) specialist, recently received the first six Series 1000 – 1500 MTU engines from Rolls-Royce that meet the new EU Stage V emission standard, the engine specialist said.

The engines cover a power range from 170-430 kW.

The order had been preceded by a test phase of several years under the most adverse operating conditions in order to ensure the trucks would be guaranteed a reliable, cost-effective upgrade, according to Rolls-Royce. To this end, MTU’s off-road engine series were optimised to comply with the emission standard and a new exhaust aftertreatment system introduced.

In preparation for the more stringent emission requirements, Rolls-Royce had made two Stage V prototypes available to Bell for field trials in 2016 – a 260 kW MTU 6R 1000 engine and a 430 kW 6R 1500 were successfully tested in the hot, dusty climate of South Africa and for the tough conditions encountered at extreme altitudes of up to 3,000 m.

Bell and Rolls-Royce with the MTU brand have been working together closely since the 1990s, with Rolls-Royce not only the supplier of more than 1,000 MTU engines a year, but also the technology partner in all emission-related design and construction decisions – including the upgrading of the ADTs.

Stefan Rudert, Head of Sales and Application Engineering for Construction & Agriculture at MTU, said: “During the field trials, we accumulated an enormous amount of experience that goes way beyond any simulation on a test bench, since the real-life interplay between the engine and the vehicle affects the behaviour. Data obtained during the field tests, which we collected from sensors mounted on the engines was subsequently used in the configuration of the components.”

The new Stage V engines, which Bell will successively upgrade to, besides MTU’s current SCR exhaust technology, also include a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF), with all components installed in a compact one-box solution behind the driver’s cab, according to the company.

“Another positive aspect of the new emissions technology is that it reduces fuel consumption,” the company said. “To prepare for the upgrade to the new emission regulation, Rolls-Royce had around 100 MTU engines undergoing trials with various vehicle manufacturers.

“In total, over 110,000 operating hours were accumulated as a result, with individual engines running non-stop for more than 4,000 hours. Since the trials had started at an early stage, the MTU engines were certified in accordance with the EU Stage V regulations by mid-2018, marketable and ready for series production.”

Doosan ups the distribution ante in North America

Doosan’s Infracore North America division has opened a new 100,000 ft² (9,290 m²) parts distribution centre serving its dealers and Doosan customers in the US and Canada.

Strategically located, the new parts distribution centre allows Doosan Infracore North America to provide both dealers and customers with better service options, deeper inventory and faster parts delivery, the company said.

The centre is located adjacent to the Doosan Infracore North America headquarters in Suwanee, Georgia, some 48 km northeast of Atlanta.

Edward Song, CEO, Doosan Infracore North America, said: “Doosan is committed to being a top-five construction equipment brand in North America and this new parts distribution centre illustrates our promise to support our dealers and our customers with parts availability and prompt delivery.” He said the company can “significantly reduce” shipping costs and can provide less than two-day delivery on a majority of its genuine parts delivered from the warehouse.

The facility, managed by leading contract logistics firm DHL Supply Chain, is designed for Doosan parts distribution and shipping. It will stock around 40,000 stock keeping units that can be shipped to service Doosan construction equipment throughout the US and Canada.

The parts distribution centre will house a majority of Doosan parts, with only some low-volume parts needing to come from Doosan manufacturing facilities around the globe, the company said.
Doosan supplies a variety of equipment to the mining sector including excavators and ADTs.

Terex TA400 ADTs stand up to Indonesia coal mine test

Ten Terex TA400 articulated haul trucks have been proving their worth removing overburden from a coal mine in East Kalimantan, Indonesia.

The trucks are being used by local mine owner PT Tambang Berkat Karunia for a five-year project in Batuah.

“We have the machines working for up to 18 hours a day, removing overburden and transporting it across the soft terrain,” said Bhisma Dian Resnadi, Operation Manager for PT Berkarya Abadi Selalu, a subsidiary of TBK tasked with undertaking the work.

The Terex Trucks TA400 is perfectly suited to perform in large-scale construction projects, quarries and mine sites, according to Terex. With a maximum payload of 38 t, TBK’s 10 TA400s can collectively haul 380 t, which is equivalent to the weight of around 70 Asian elephants.

“With the ground being so soft at the Batuah mine, we needed trucks that could perform in challenging conditions – and TBK’s TA400 haulers enable us to do just that,” Bhisma said. “Some of our operators had never used a TA400 before. They’ve said that they are very impressed with the performance features – especially the engine – as well as how advanced the technology is.”

Established in 2018, TBK is still relatively new to the industry. It purchased the Terex Trucks haulers from PT United Equipment Indonesia, the official Terex Trucks dealer in Indonesia since 2009.

Bhisma said: “We decided to go with Terex Trucks machines because they are known for being strong and reliable. Price factored into our decision, too. Given the quality of the TA400, the cost is very reasonable. As the project progresses, we might decide to purchase additional Terex Trucks haulers.”

The TA400 is powered by a six-cylinder Scania DC13 engine that is both fuel efficient and delivers low cost of operation, Terex says. It also comes fitted with a modulating transmission retarder, teamed with an efficient exhaust brake and fully enclosed oil-cooled multi-disc brakes, resulting in optimum control and increased safety.

In addition to this, all three axles are in permanent (6 x 6) all-wheel drive, which enables the TA400 to achieve great traction with minimal driveline impact and wheel spin. This results in reduced tyre wear.

To ensure servicing the TA400 is quick and easy, it comes with ground level test points and a fully tilting cab, as well as an electronically raised hood, which also results in reduced downtime.
