The German company’s new tiltrotator system is taking progressive steps towards sustainability, applying smart technology to reduce energy consumption and is adapted to be ready for the electrification of excavators.

“Normally in an excavator, all systems start up, with high demand for energy,” said engcon Germany country manager, Alexander Stenmans. “This [third generation] is optimised to bring the energy where it’s needed.”

The second half of 2022 sees engcon begin production of the new tiltrotator. Its technology is based on a newly developed type of valve, in combination with smart software that works with the excavator’s load-sensing hydraulic system.

This optimises both the tiltrotator’s functions and the excavator’s movements, which the company says leads to smoother digging with higher precision. The excavator’s wear, and need for maintenance, simultaneously decreases, says engcon.

With an app, the 3G tiltrotator system also enables a higher degree of individual customisation in, for example, connected remote diagnostics and mobile support.

For compatibility with modern excavator systems, engcon also builds in a newly developed tilt and rotation sensor as standard in its third-generation product.

Initial 3G excavator models are the EC319 (14-19tonnes) and EC314 (9-14tonnes). The model programme will then be steadily expanded.

The X02 is accompanied by a complete range of work tools resulting in increased efficiency and versatility which convert the smallest excavators into true tool carriers.

The X02 comes with either a Direct Fit or an S30 top for the connection to the excavator. The coupler side, the bottom of the tiltrotator, is available in a mechanical locking version as well as hydraulic locking for S30.

Steelwrist says that the hydraulic lock version with the integrated front pin hook is probably the only tiltrotator in this class that has work tool safety to support CE requirements.

The X02 is positioned between the smallest TCX tilt coupler for machines below 2 tonnes and the X04 tiltrotator for excavators from 2.5 to 4 tonnes. Again, the focus with X02 has been to make a fully casted product with best strength-weight ratio and low building height.

It has a new gearbox design which makes it possible to easily eliminate play over time, lubrication free bearings for easy maintenance, valves and control module placing to protect from outer damage and, finally, a bolt-on lifting eye or lifting hook as option on direct fitted tiltrotators.

With a complete set of Steelwrist S30 work tools for the X02, including for  grading, digging, cable/trenching and asphalt cutting and ripping, the excavator turns into an efficient and versatile tool carrier.

This autumn, too, a general purpose construction and log grapple is being added to the work tool offering for the X02.

The NeoR locking screw DW12.5x160 ensures a secure and fast connection. Due to the reinforced, 15mm thick plywood, the multi-purpose panels have a fresh concrete pressure absorption of 60kN/m².

The panels are available in dimensions of 60cm x 90cm and 60cm x 150cm and offer maximum variability in manufacturing concrete columns. Square and rectangular column cross-sections with an adjustment range from 20-50cm and 5cm gradation can be formed with four multi-purpose panels at a time.

In addition to its use as column form panels, the NeoR multi-purpose panel can also be used for the end stop or as frontal end formwork by mounting the multi-purpose panel to the adjacent NeoR formwork panels using locking screws. The hole grid in the multi-purpose panel uses 5 cm intervals, so that wall thicknesses can be set with the same spacing of 10-40 cm. In addition, implementation with the standard wall thickness of 24cm is also possible.

The inside corner post and compensation panels are used together with the multi-purpose panel to form right angles. The multi-purpose panel is connected directly to the compensation panel via the integrated hole profiles by means of locking screws. In this way, wall thicknesses of 5-35cm in 5cm modular formwork and wall thicknesses of 24cm can be easily implemented in the system.

Worker safety at work is ensured by the Grip tread, which can be used as a working platform for the column form in combination with the Grip attachment. For this purpose, the accessories have been expanded to include the NeoR Multi ladder attachment for aligning the ladder and the Grip attachment.

The Smart Doc system shows in real-time how compaction develops, and links the machine data to GNSS position data. The app uses this data to create compaction reports in PDF format and is suitable for self-monitoring.

The Smart Compact compaction assistant meanwhile can further raise the quality of the compaction. It can integrate local weather data into the evaluation, while also evaluating the physical and cooling properties of the asphalt.

This allows it to determine the optimal setting for each drum separately, selecting whether compaction should be carried out with vibration, with big or small amplitude, as well as having the options of oscillation or static compaction. The driver only enters which layer is to be compacted and the system can also put the roller into ECO mode and save fuel.

This sophisticated tool incorporates a touchscreen and radio remote controls and supports work site digitalisation. All relevant process information and reporting can be displayed on the user’s smartphone without having to leave the feeding device. SPECTIVE CONNECT also offers new features, which will make work for the operator easier according to the firm. One of the key features is a new configuration tool  that helps the operator select the correct machine settings for each application.

The 10-tonne weight class is new to the Doosan range and the DX100W-7 offers a high performance for urban and road maintenance applications. The integral 1.35-tonne counterweight ensures the highest stability for lifting work in combination with the articulated boom and long arm. The boom ensures that the operator can position the machine as close as possible to trucks during loading.

In addition, the DX100W-7 offers maximised lifting capacities and digging forces, as well as satisfying a requirement in some countries for a wheeled excavator with a travelling height of under 4m.

Other safety features include a ROPS cab with a premium seat as standard. An operator can use the large touch screen to easily browse all machine settings, including the view from the standard side and rear view cameras. The availability on the DX100W-7 of an optional 360° all-around view camera, linked with an optional ultrasonic detection system is another exclusive for a machine of this size, says Doosan.

With 75kW of power at 2000 RPM provided by a Doosan D34 G2 Stage V engine, the DX100W-7 has the highest engine power, hydraulic flow and traction force in this class. The high flow from the smooth and precise hydraulic system can drive all kinds of attachments. In addition, there are two different pumps providing independent hydraulic flow for the transmission and to fully power hydraulic tools on the front end.

The new DX100W-7 comes with DoosanCONNECT TMS 3.0 wireless fleet monitoring system.

Both machines are powered by 6.7litre Cummins diesels rated at 168kW for the TC7A and 186kW for the TC11A and have hydrostatic drives, featuring proven hydraulic components from Rexroth. The firm says that the operators benefit from larger and more comfortable ROPS/FOPS cabs with better all round visibility than competing machines.

The machines are said to good offer good traction even in the worst conditions and can cope with 50% slopes. The suspension systems feature walking beams and six rollers, a configuration said to ensure a combination of high traction and smooth running. The smaller machine has a dump area of 3.5m3 while the larger unit has a dump area of 5.25m3. Fold down sides for the rear area also allow the machines to be used for carrying equipment for projects on remote sites. The machines can also be equipped with access equipment, loader cranes or compact concrete mixer units for example.

No two conveying systems are alike, even if the primary task of transporting bulk material from A to B appears comparable. The components and the system must be adapted to the material being conveyed. The mass flow to be conveyed and height differences that need to be overcome over the length of the conveyor line are important factors that must be addressed when designing a system.

The right layout is all-important and the BEUMER Overland Layouting Tool is central for ascertaining the ideal layout for the system at an early stage of the project and designing the ideal conveying solution together with the customer.

It generates a digital 3D model of the conveyor in the virtual landscape during project planning, more or less automatically, according to the company. The critical topography data can either be provided by customers or drones that capture terrain data. These 3D visualisations are also ideal for supporting mining companies in their public relations work.

Important factors such as cut-and-fill volumes - the necessary excavation work - and the required steel structures for the conveyor can be evaluated and illustrated on this basis. This procedure considerably accelerates the project planning process and enables BEUMER to provide project-critical data to the customer at an early stage of the project.

Topography has a significant influence on the design of the conveying system. An in-depth analysis of various dynamic load cases and a thorough investigation of the technically feasible horizontal and vertical curve radii must be conducted to design the system in the most efficient and environmentally friendly way. This is especially true for longer and more difficult conveyor lines. Potential obstacles that must be considered during the planning phase include residential areas, roads and rivers.

Today, BEUMER can design curved overland conveyors of up to 20km or longer without the need for a transfer tower. The conveying capacities of a system like this are more than 20,000 tonnes per hour.

Slotting into the range between the existing R 926 and R 930, the R 928 weighs under 30tonnes and this makes it easier to transport. Meanwhile, the sophisticated, semi-automatic machine control package is said to ensure precise and productive operation, without the need for reworking. Factory-installed 2D and 3D machine controls will be available in future for Liebherr’s Generation 6 and 8 Liebherr crawler and wheeled excavators as optional equipment.

Improvements have been made in arm and boom structure, undercarriage and attachment groups by using more durable materials for the H4 Series. The 500 LCHD has a more durable structure and offers high performance and long-life that are essential for long hours on duty in marble quarries, mines and large construction sites.

The 52,000kg 500 LCHD  with its Pentagon-type chassis is powered by a stage V-EU certified ISUZU-6UZ1X engine producing 270kW at 2000 rpm. Travel is fully hydrsostatic.

The hydraulic system incorporates double variable displacement axial piston pumps with a maximum flow rate of 2 x 376  litres per min.

Cat Grade with Slope Assist automatically maintains pre-established blade position without a GPS signal, so no additional hardware or software is needed. Factory integrated Cat Grade with 3D uses GPS to control the blade so you can get to design plan faster and it has no blade masts. The antennas and receivers are housed in a low-profile roof-mounted spoiler.

In the cab, the operator interface is intuitive and easier to use, thanks to a 254mm touchscreen Android OS platform that operates like a smart phone. Slope Indicate shows machine cross-slope and fore and aft orientation right on the main display to help operators with slope work.

For added safety, there is a standard high definition rear view camera that shows prominently in the main display.

The machines are the well-accepted Doosan models built in Norway and now being offered in Hyundai branding following the tie up between the firms.

The firm claims equal weight distribution due to the sloping rear chassis frame design, which is said to deliver stability by distributing more load towards the centre of the machine and resulting in a low centre of gravity. The machines also have the proven tandem rear axle bogie configuration, which is said to offer a higher degree of articulation than competing designs and optimises ground contact to maximise traction. The machines also feature the articulation joint turning ring mounted close to the front axle, which further helps to equalise load distribution between the front to rear and across the front axle during steering.

The trucks are powered by Stage V-compliant Scania diesels. The HA30A uses a five-cylinder, 9.3litre, DC9 turbocharged diesel, developing 276kW and 1,876Nm of torque. The larger HA45A employs a six-cylinder, 12.7litre DC13 diesel engine, producing 368kW) and 2,476Nm 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. The engine canopy tilts forward for access to filters and fill points, while the cab structure can be tilted to provide access for repair and maintenance.

Hyundai’s Himate telematic monitoring system is fitted standard, with satellite and GSM connectivity. This allows customers to monitor productivity, fuel consumption, system warning and maintenance status remotely, reducing downtime and improving fleet utilisation.
