Doosan is presenting many new products for the first time at the Hillhead Digital event from 30-31 March 2021. They include the company’s new DL-7 wheel loader, DX-7 crawler excavator and ADT ranges, introducing a host of next generation machines, driven by powerful new Stage V engines and providing higher productivity, increased fuel efficiency and a low cost of ownership, coupled with a fantastic environment and experience for operators. New Award-Winning Design Among the new ‘DL-7’ wheel loaders at Hillhead Digital is the top-of-the-range DL580-7. The new DL-7 range is the culmination of the first complete redesign of the Doosan wheel loader range in 10 years, with the exterior design, in particular, undergoing a complete transformation. Redesigned buckets offering up to 7% more capacity ensure the seven new Doosan DL-7 wheel loaders provide easier and faster loading with maximum bucket capacities from 2.8 to 6.4 m3. This provides increased productivity for a very wide range of material-handling applications.   The new cab offers a greatly improved field of vision for the operator, with blind spots around the cab minimized and a 14% larger glass window area compared to the previous DL-5 models. Inside the cab, the DL-7 wheel loaders offer significantly enhanced operating comfort, an enhanced steering system and advanced electronic controls. Using the new Doosan Smart Key system on the control panel in the cab, the operator can start the machine using a keyless device, helping to prevent machine theft. The Smart Key system provides remote door control, door lock and unlock, door release, searching and other functions. More Firsts in Doosan Crawler Excavators Among the Doosan crawler excavators making their debut at Hillhead Digital is the 80 tonne DX800LC-7, the largest excavator ever manufactured by Doosan. The DX800LC-7 excavator is powered by the new stage V version of the well-proven Perkins 2506J diesel engine, providing a high power output of 403 kW (548 HP), more than any other machine in this class. The high output of the engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-Ecopower+), providing a best-in-class hydraulic flow of 1008 l/min and a high system pressure of 343 bar, providing best-in-class performance, with higher productivity, lower fuel consumption of 45 l/h in heavy applications with bucket sizes from 4.6 to 5.2 m3 and smoother controls. Other standard features include the 360° around view monitoring system and the full package of powerful LED work lights for increased safety and the convenience and reassurance provided by the SKF Auto Greasing System.  Choice of Boom and Swing Modes To provide optimized operations when working with the DX800LC-7 excavator, the operator can switch between two modes – Boom or Swing – giving priority to boom or swing movements, respectively, so they can best match how they are using the machine to the application they are working on.  Faster working speeds are ensured by the 2-spool Boom Down Regeneration system in the DX800LC-7, which also reduces fuel consumption. The 2-spool hydraulic system for the bucket cylinder also increases hydraulic flow and the working speed of the bucket, again reducing fuel consumption. The DX800LC-7 also has a boom/arm cylinder lock valve (anti-hose burst valve) as standard for increased safety, preventing accidents caused by hydraulic hose rupture on site. Like the DX800LC-7, the new DX530LC-7 Stage V 50 tonne crawler excavator, also included for the first time at Hillhead Digital, offers the strength and productivity needed for heavy duty work such as large-scale earthmoving, moving rock, pulling down buildings, secondary breaking, loading haulers and pipeline projects found on quarrying and mining, highway, aggregate, demolition, utility and general construction projects. To meet Stage V engine emission regulations, the DX530LC-7 excavator is powered by the new Scania DC13 Stage V compliant diesel engine, providing a higher power output of 294 kW (394 HP). The Scania engine offers a new solution to exceed Stage V with super-efficient DOC/DPF+SCR after-treatment technology to ensure minimal emissions. Best Performance in 50 tonne Class In the DX530LC-7, the enhanced performance of the DC13 engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-Ecopower+) and the new generation Smart Power Control Technology (SPC3), providing an overall fuel efficiency increase of 11%. Increased pump capacity and the higher power of the engine produces up to an 8% increase in productivity, the best-in-class performance in the 50 tonne market. A Wealth of New Features on the ADTs The Hillhead Digital display also comprises the new DA30-7 and DA45-7 Stage V compliant articulated dump trucks (ADTs) from Doosan. The DA30-7 has a payload of 28 tonne, while that of the DA45-7 is 41 tonne. The DA30-7 is powered by the new Scania Stage V compliant DC09 9 litre diesel engine providing 276 kW (375 HP) of power. The DA45-7 is driven by the new Scania Stage V DC13 13 litre diesel engine with an output of 368 kW (500 HP). Both new ADTs have been upgraded with a range of features including a new cab and a new self-levelling front suspension that adjusts itself independently depending on the operating conditions to ensure a comfortable working environment for the operator. Together with several striking visual changes, there are a number of functional changes on the new ADTs which improve safety, comfort and serviceability. These include a new positioning of the diesel and AdBlue tanks. The latter are now much lower than before, allowing the operator to fill both tanks whilst standing next to the machine (‘ground level filling’).  The new ADTs are equipped as standard with a real-time payload measuring system with a light indication for excavator operators, which will help them to place optimal loads in the ADTs to ensure excellent productivity and low fuel consumption. The greasing system has also been relocated to make it easily accessible from ground level. Space has been provided above the automatic lubrication system (which is standard) for additional grease cartridges and a filling pump. DoosanCONNECT Fleet Management System as Standard All the Doosan machines 14 tonne and above are factory-installed with the latest DoosanCONNECT

Are you considering buying a snow blower this winter or do you already own one? Like a car or a motorcycle, snow blowers have mechanical parts inside that need to be taken care of regularly. Keeping up with regular maintenance tasks for your snow blower is crucial to ensure your equipment is ready to be put to work when the snow begins to fall, every time. Here are some basic maintenance tasks to keep your equipment running smoothly. After 5 hours of snow blower use Before doing anything, disengage all control levers and stop the engine of your snow blower before cleaning, repairing or inspecting it. If your snow blower is new, you will need to replace the engine oil after the first five hours of use. This will ensure your machine works properly in the future, as it will clean out any residue that was left during assembly. After the initial break-in period, make sure you check the oil level after each use. Also, don’t forget to inspect and clean up the exhaust area and air filter (if your machine has one). After 25 hours of snow blower use Once you have used your machine for a longer period of time, it’s time to check the spark plug for any signs of damage like deposit or cracks. If your spark plug has some damage, it’s best to replace it with a new one. What’s more, spark plugs are usually quite affordable, so it’s not a bad idea to have a couple backups on hand ahead of time. In addition, it is recommended that you lubricate the auger shaft at least once a season and again before storing it for summer to prevent rust. After every season To keep your snow blower running smoothly season after season, you will need to change the old engine oil in your machine. This should be done every season and after every 50 hours of use. This will ensure that your snow blower keeps operating properly and without risk of poor performance or expensive repair bills. Also, inspect the belts for any signs of fraying or splitting. Some machines like Cub Cadet’s three-stage snow blowers have more than one belt—make sure you install new ones that are compatible with your snow blower brand and model. Finally, it is advisable to replace the spark plug even if there are no signs of damage after every 100 hours of use. Other things to keep an eye on The basic maintenance tasks mentioned above are crucial to ensure that your machine works well. However, there are other items that can wear out, such as the scraper bar or skid shoes, that you should look for when servicing your machine. Be sure to check the machine thoroughly for other signs of developing problems from time to time for any signs of damage and replace or repair as needed. Don’t forget to refer to your operator’s manual for specific guidance about how to best service your snow blower. That’s it! Following these simple maintenance tasks should be enough to ensure that your snow blower performs at its best over the course of its lifetime.

The DD105 and DD105 OSC asphalt compactors from Volvo Construction Equipment now come equipped with Tier 3/Stage IIIA engines for emerging markets. Thanks to the integration of a Tier 3/Stage IIIA engine, the DD105 and oscillatory variant DD105 OSC double drum compactors are now available in emerging markets. These fuel-efficient and productive machines are equipped with an 86.3kW Tier 3/Stage IIIA engine that automatically adjusts output according to jobsite requirements, delivering power only when needed. Other smart features include Eco mode – which cuts fuel consumption by up to 30% without affecting performance – and an auto-idle function that reduces engine speed when the roller is stopped. Comfortably productive These robust machines are built to work hard but that doesn’t mean they can’t be comfortable. Volvo Construction Equipment (Volvo CE) prides itself on designing machines with the operator in mind. The company makes some of the most comfortable – and therefore productive – machines in the industry and the DD105/DD105 OSC is no exception. The ergonomically positioned controls and joystick guarantee effortless maneuverability, while the efficient climate system also helps keep the operator comfortable. The rear-mounted engine combined with a curved front glass panel and padded floor contributes to low levels of noise and vibrations within the cab – for a smooth and quiet ride. Safety and ease of operation are enhanced by the expansive front windshield which maximizes the view down to the drum and spray bars. The structural pillar supporting the roof is located at the rear of the cab, meaning the three front glass panels provide operators with an entirely unobstructed view of the road. When working close to obstacles, the fully adjustable operator station can rotate and slide to the side of the cab to easily provide a view down the edge of the asphalt – increasing safety and rolling precision. Smart technology, efficient compaction The 10-tonne compactors come fitted with a 1,680 mm wide drum whose unique design halves the power needed to start the vibration system with no compromise on productivity. This reduces the operator’s exposure to machine vibration while also ensuring a smoother finished mat. Fitted with the flexibility of the Volvo oscillation technology – which eliminates vertical vibrations – the DD105 OSC offers high compaction performance while producing a non-damaging oscillation movement. This transfers less stress to the surrounding surface, enabling compaction in more delicate application areas, such as bridges, over pipes and close to residential areas. Additionally, when compacting against a cold joint, the risk of damaging the cold surface is reduced, and the material can be more effectively compressed to seal and protect the surface. The oscillatory movement of the drum can also improve surface smoothness, by re-aligning the material. To account for the increased wear on the drum surface, the Volvo DD105 OSC roller has a hardened, abrasion-resistant alloy steel drum shell, which increases longevity. Also helping operators to achieve a high mat quality in less time is the Compact Assist function. Powered by the Volvo Co-Pilot display, Compact Assist provides access to a set of work-enhancing apps – including pass mapping and temperature mapping – which provide real-time insight into the work being undertaken. With easy access to clear and detailed data, the operator can eliminate any damaging over-compaction and ensure complete coverage of the working area. Unrivaled uptime The Volvo DD105 and DD105 OSC both feature an automatic water spraying system with triple filtration that provides uniform coverage and variable flow, as well as helping prevent material pick-up. Furthermore, the two water pumps alternate during normal operation. In the rare event of a pump malfunctioning, a constant flow of water to the drum surface is automatically retained. The large 740-liter water tank allows for increased refill intervals, also helping to keep downtime to a minimum. Moreover, the tank’s low positioning affords the machine a low center of gravity for excellent stability and can be quickly and easily refilled at ground level. The double drum compactors are designed for simple servicing and maintenance. The swing-up hood provides complete access to the engine and hydraulic components for efficient service inspections. Using a single key, technicians can access exterior service hatches, while fuses and relays are safely stored in the cab. With ground-level access to the engine, radiator, battery, and filters, daily checkpoints are unobstructed. And when it’s time to leave the jobsite and load into the truck, operators can rely on the Anti-Slip Control to avoid damaging the pavement. To further optimize machine availability, customers can use CareTrack, the Volvo telematics system, to access a wide range of machine monitoring information designed to save time and money. When additional support is needed, the extensive Volvo dealer network is on hand to provide advice and solutions, which can help customers towards achieving their business goals and objectives.

Heavy equipment has laid the foundation of great civilizations and modern communities. From the Great Pyramids to the 35-year construction of the Interstate Highway and high-rise buildings, these construction tools dug earth and moved stones to make way for impressive engineering and architectural feats both ancient and modern. Their history is intertwined with the rise of equipment technology, and promises a bright future for the industry – as can be seen in well-established companies such as Fortis Heavy Duty. Muscle Power in Ancient Times  The Egyptian civilization was the first ever to use heavy equipment in terms of manual and animal labor to operate simple levers, pulleys and cranes. In 2500 BCE Imhotep, an Egyptian chancellor regarded as the world’s first architect orchestrated the building of the Great Pyramids using a system of rollers, ramps and ropes. The Romans also used this system. Moving huge slabs of stone was done using smooth ramps and rolling pins. Cranes were used to create the Roman arch, and other structures. Vitruvius, a Roman engineer, described early heavy equipment in his treatise known as De Architectura. These were made of wood, and used treadwheel for power. 1800s: Steam, Traction and Hydraulics Much of what the ancient civilizations used was still in operation until the 1800s, primarily for agricultural purposes – far from super-mechanized engines and heavy equipment undercarriage parts. In 1886, American inventor Benjamin Leroy Holt created a combine steam harvester. Two years later, John Froelich created a gasoline-powered tractor with forward and reverse gears. In 1890 Holt once again produced a steam-powered tractor. These inventions proved beneficial to the agricultural industry as it allowed the transition from animal-power to more powerful steam engines. Apart from the tractor, steam engines also fueled dredgers and steam excavators.  Thomas Aveling also created the traction engine in the mid-1800s and is known as “The Father of the Traction Engine.” His invention has made a lasting impact in the development of succeeding heavy equipment. 1900s: Rise of Heavy Equipment Vehicles By the 1900s, the second phase of The Industrial revolution was well underway and created a huge demand for heavy equipment in various industries. Track vehicles emerged at this time, with the first successful patent made by Alvin Orlando Lombard in 1901. In later years he would invent the first commercial tractor crawler, the forerunner of today’s tracked construction vehicles. Heavy equipment was also introduced to the construction industry in the early 1900s. In 1907, the Galion Works built motor and pull graders, steam and internal combustion rollers, wheeled scrapers and hydraulic cranes. Adaptations were made on these vehicles to suit the demands of construction. The bull graders were introduced in 1920s. It quickly grew in popularity, and in the 1930s it was renamed the bulldozer. This vehicle has since evolved into the bulldozer we know today, hauling boulders and tree stumps from the earth. Bucket-wheeled excavators also began in the 1920s, as digging machines for the mining industry. They have proved beneficial to surface mining operations over the years. Dump Trucks were also introduced at this time, also known as tipper or dumper trucks. 1930-1960: Tough Times and Tough Builds This 30-year period is marked with tough times, from the Great Depression to WWII. There was also notable construction taking place, including the San Francisco Golden Gate Bridge and the beginning of the Interstate Highway. This is often considered as the boom of the heavy equipment industry, as vehicles became monster-sized to address the demands of the massive interstate construction. The world’s biggest dragline, shovel and 360-ton truck emerged.  1970-1980: Embargo and Recession Demand for machinery continued to increase during this period, and equipment became more sophisticated. The Arab embargo of 1973 also caused greater demand. It is at this time that safety measures were given for heavy equipment. 1990-2010: Compact and Efficient Vehicles Machinery now utilized diesel engines, and while this shift improved efficiency, it had negative effects to the environment. Environmental compliance demanded that manufacturers build cleaner and more efficient engines. The economic recession: the third to hit the heavy equipment industry, has created a trend favoring rent rather than purchase of heavy equipment. Manufacturers are compelled to comply with the specifications rental companies for durability and efficiency, as well to ensure compliance with continuous emission-phase testing from 2001-2008.  2010-2019 The heavy equipment industry is one again seeing growth. Advances in construction equipment came in the form of telematics, electromobility and autonomous machinery. IoT, or the Internet of Things is also employed to increase machine life cycles.
