< PreviousB obcat has launched a new range of sweepers that form part of the company’s portfolio of road maintenance attachments, the most comprehensive on the market. The fi ve new sweepers are designed for versatility and are approved to use with many diff erent Bobcat tool carriers, including skid-steer and compact track loaders, compact wheel loaders, small articulated loaders and rigid frame telehandlers. Now part of Bobcat’s road and pavement equipment selection, the sweepers comple- ment a wide choice of products for this sector, including planer, wheel saw, soil and asphalt spreader, grader, trencher and angle broom products. Combined with the grow- ing line-up of Bobcat tool carriers, these pro- vide high performance solutions for asphalt, concrete, road, pavement surface repair and many other applications. Daniele Paciotti, product line manager for attachments, Bobcat, said: “All asphalt surfaces need to be maintained and repaired regularly to extend their lifetimes. At Bobcat, we continue to invest in expanding our range of road maintenance attachments as we see growing demand. We now off er BOBCAT LAUNCHES NEW RANGE OF ATTACHMENTS FOR ROAD MAINTENANCE the widest portfolio of compact solutions for road repair on the market, providing a choice of products from planers, sweepers and wheel saws to our recently added light compaction line-up.” The fi ve sweeper models provide sweep- ing widths from 110 to 215 cm, with bucket capacities from 0.22 to 0.44 m3 for collection of debris. All model sizes are now available with unifi ed platform features. They feature tougher, longer life heavy-duty bristles, and in response to customer feedback, Bobcat has developed a new optional integrated wa- ter tank unit, installed on top of the sweeper ROAD CONSTRUCTION 30 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021itself, with a cleverly designed, optimally front-positioned sprinkler system. In addition to road applications, the Bobcat sweepers cover a wide range of jobs from cleaning, recycling, construction and demolition to many tasks in agriculture. Bobcat sweepers can sweep and collect dirt or other debris in both forward and reverse directions. They are suitable for cleaning parking lots, pavements, docks and warehouses, as well as industrial and recycling facilities, construction and demoli- tion sites and animal sheds in agriculture. The sweeper attachments employ the Bobcat plug and play system, which enables the operator to install and change attachments in less than a minute. The key to this is Bobcat’s attachment control device featuring a 7-pin connector, which recognizes the at- tachment connected and allows the operator to utilize all of the features of the attach- ment from within the cab right away. Planer attachments: Suitable for repair- ing not only potholes, surface cracks and ice damage, but also for milling surfaces and for working around manholes, Bobcat planers cover cutting widths from 35 up to 120 cm. Other uses include creating cuts for recessed lane markers; matching uneven pavement surfaces; producing vertical edges for pave- ment repairs; cutting drainage in parking lots and for tapering edges of roadways. Wheel saw attachments: Bobcat’s rugged wheel saw attachments cut through asphalt, concrete, frozen ground, wire mesh and other hard materials with more precision than either air or hydraulic breakers. They can be used for road repair and cutting trenches for laying water, gas, electric and fi bre-optic cable lines. The trench cleaner raises and lowers hydraulically and, depend- ing on the model, cutting depth ranges from 15 to 80 cm. Bobcat also off ers wheel saws with segmented wheels allowing the user to quickly change the width of the wheel (50, 80, 100 or 120 mm) in the fi eld, instead of replacing the complete wheel in a workshop, a saving of 10 hours in the process. Soil and asphalt spreader: With a standard operating width of 190 cm or optional width of 196 cm, Bobcat’s soil and asphalt spreader can be used to lay asphalt and other materi- als to create pavements, widen and repair existing roads, backfi ll, pave over and cover trenches, and lay sub-base materials. Due to its off set feature, this attachment can also lay asphalt without the loader needing to pass over the spread material, thus ensuring an unblemished and smoother fi nish. ROAD CONSTRUCTION 31 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021T he new-generation of Hamm pneumatic-tyre rollers, the HP series, has a range of potential applications extends from soil stabilisation, cold recycling and landscape gardening, tight through to fi nal compaction and surface sealing in asphalt construction. Hamm has developed a uniform platform as the basis for all model variants in every market throughout the world. Based on this, Hamm is also continuing to off er the pneumatic-tyre rollers in diff erent basic versions: On the one hand, the HP 180 or HP 180i model with a minimum working weight of 8 t and a maximum operating weight of 18 t and, on the other hand, the HP 280 or HP 280i model with working weights between 10 t and maximum 28 t. In doing so, Hamm provides individual markets with the respective model to suit their regional demands with regard to weight classes and equipment versions. The HP 180i and HP 280i models (both with Easy Drive operat- ing concept) comply with the requirements of the emissions standards EPA Tier 4 and EU Stage V, while the HP 180 and HP 280 models are designed for Tier 3 markets. The HP series also off ers a modern, spa- cious operator’s platform or panoramic cabin with maximum visibility over the machine and the construction site. In this respect all models comply with the new ISO 5006-2017 operator’s fi eld of view standard which is markedly stricter than the previous provi- sions. In terms of machine design, Hamm is sticking with the proven asymmetrical frame concept in the HP series. This is not only a hallmark, it is also a quality advantage because it follows the track off set between the front and rear wheel sets and always allows a clear view of the outer fl anks of the front and rear wheels. The hydrostatic rear-axle drive, combined with a sensitive control system, allows the right speed to be set in every working situ- ation. The specifi ed working speed can be conveniently adjusted using the rotary knob, an important prerequisite for homogeneous compaction. The intelligent drive control allows for smooth, even acceleration and braking, which prevents uneven compaction. Thermal aprons are available for all models in the HP series. Diesel-powered tyre heating is a new feature available on the HP 180i and HP 280i models. The integrated tyre heating is not operated using gas, but rather with diesel from the fuel tank. This NEW FEATURES OF HAMM PNEUMATIC-TYRE ROLLERS BOOST JOBSITE PRODUCTIVITY ROAD CONSTRUCTION 32 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021means that the often very costly transport and the time-intensive replacement of the cylinders are completely eliminated. With this solution, Hamm has also eliminated a source of danger because there are no naked fl ames and, as a result, no risk of ignition, when it comes into contact with oil or the additive, for example. Another permanent feature of the new tyre heating is automatic temperature control. After preselecting a minimum and maximum value, the control maintains the temperature in this range. The driver can view the current temperature via the display. The tyre heating also does not aff ect the ballasting of the machines. The maximum permissible operating weight is possible, irrespective of this. When paving special asphalt that is rather diffi cult to process, the sprinkling of the pneumatic tyres with additive is essential for high-quality compaction. By completely redesigning the additive-sprinkling system, Hamm is creating optimal prerequisites for easy handling and the highest level of compaction quality. The system off ers several advantages; for example, the fi lling of the additive concentrate is time-saving, as premixing is not required. The dosage can then be regulated in diff erent levels from the driver’s platform. The water and additive are mixed automatically, which guarantees a lasting optimal mixing ratio without demix- ing. The driver also always has the option to monitor the fi ll level via the display on the control panel. It is also possible to convert the sprinkling from water to additive at any time from the driver’s platform. The HP series models also have a large, newly designed water tank with a volume of 650 l. Like the diesel tank, it is generously dimensioned so that the machines have suffi cient capacity for a full working day without stopping to refi ll. Hamm also off ers a supplementary water tank with a volume of 1,500 l for all HP series models. It may be used as a water reservoir for the sprin- kling system, but also serves as an easily quantifi able, fl exible supplementary weight. Operation of the supplementary tank is remarkably easy because it is connected to the basic water tank by means of intercon- necting pipes. To facilitate fast refi lling, the developers have provided a C-pipe connec- tion to complement conventional fi lling. It enables the entire tank to be fi lled in around three minutes. A pump is also fi tted to allow complete discharge. ROAD CONSTRUCTION 33 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021E urope is home to many rail, road, and canal tunnels. With rail travel being a greener mode of transport, the region will see more tunnelling projects come about in the next few years. Scottish manufacturer Terex Trucks explains why these undertakings require extra tough machinery and how its articulated haulers such as the TA300 and TA400 get the job done in these challenging working environments. 1. Maximum uptime for a 24-hour schedule Tunnelling is no nine-to-fi ve job: the projects usually operate on a very tight schedule, which means the machines working in the tunnel FIVE REQUIREMENTS FOR ARTICULATED HAULERS WORKING ON TUNNELLING PROJECTS have to follow an intense schedule and usually run around the clock, seven days a week. Any unscheduled downtime can cause delays and increases costs, so machine reliability and availability are important requirements. To ensure maximum uptime, Terex Trucks uses a long-life transmission fl uid that extends oil change intervals. The TA300 has a maintenance interval of 4,000 hours and the TA400’s transmission has an oil change interval of 6,000 hours. Terex Trucks has also extended the maintenance life of the actuation hydraulic fl uid to 4,000 hours. This does not only increase uptime; the reduction in consumption and disposal of fl uids also helps customers to minimise the environmental impact of their operations. The machines’ magnetic suction fi lters further improve machine availability by reducing the risk of contaminants entering the hydraulic system. This keeps the hydraulic oil cleaner and prolongs hydraulic component lifecycles. 2. Operational safety With the TA300 and TA400’s exhaust brake, operators don’t need to use the brakes when driving down an incline in a tunnel. The machines’ modulating transmission retarder 34 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021 TRUCKSis coupled with an effi cient exhaust brake and fully enclosed oil-cooled multidisc brakes, to provide high levels of machine control and operational safety. When working in a tunnel, visibility is key. To ensure safe operations, Terex Trucks haulers are equipped with eff ective hazard area communications, including indicators for left and right as well as directional lights, often backed up by additional supporting lights. A cabin mounted fl ashing beacon provides a brighter light output even in harsh conditions, and the reverse audible alarm and fl ashing light warn anyone in the hauler’s path that it is moving backwards. 3. Strong and fuel-effi cient engines Excavating a tunnel creates tons of debris. To move the rocks out of the way, haulers sometimes have to drive for many kilometres to reach the end of the tunnel, going up and down inclines with their ton loads. This puts equipment to the test, and to deliver an effi cient performance a powerful engine is key. Thanks to a drivetrain that’s perfectly matched with the engine, Terex Trucks haulers deliver powerful performance and excel in demanding work environments. The TA300 and TA400 are both equipped with Scania engines. The TA300 is powered by a Scania DC9 engine, which develops gross power of 370 hp (276 kW) and a maximum torque of 1387 lbf ft (1880 Nm), and the TA400’s Scania DC13 engine develops gross power of 331 kW (444 hp) and a maximum torque of 2,255 Nm (1,663 lbf ft). Both the TA300 and TA400 have recently been updated with an EU-Stage V emission- compliant engine and now boast a reduction in fuel consumption of up to 7% (compared to the Stage IV machines). This improvement is achieved with advanced engine control and eff ective fuel injections. In combination with its latest upgrade to a highly effi cient 8-speed transmission, the Stage V TA300 even delivers fuel consumption savings of up to 10%. The TA300 and TA400 come with three- stage aspirated air fi ltration, which provides increased engine protection to lengthen maintenance intervals. An eff ective power- to-weight ratio of the haulers ensures that material is moved as quickly as possible. 4. Comfortable working environment Working in a tunnel is not only challenging for machines, but it is also a tough environment for operators. That’s why Terex Trucks has improved operator comfort and upgraded the cabs of the TA300 and TA400 with a high- performance heating and air-conditioning system. The sealing elements have installed pressurised properties, which helps keep the in- cab temperature stable and minimizes particle ingress. 5. Maintenance For tunnel projects especially, the ease of maintenance matters when contractors choose a hauler. To increase the availability of machinery, servicing should be as easy and safe as possible. Both the TA300 and TA400 have a fully tilting cab for easy access, and the electronically raised hood allows technicians to reach the engine service points quickly. In addition, most maintenance can be conducted at ground level and there’s no need to remove multiple parts. With the Terex Trucks Haul Track Telematics system, customers always know how their haulers are performing, which helps to better plan maintenance. If a machine is underperforming, customers will notice it, which means they can detect and investigate any issues quickly. 35 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021 TRUCKSCONTINENTAL TESTS TYRE PROTOTYPES FOR ELECTRIC TRUCKS C ontinental is currently performing test drives in Germany with an electric truck produced by Futuricum. The 19-ton truck is equipped with the largest truck battery in Europe on board, which allows a range of up to 760 kilometres without freight. The current test series are about increasing effi ciency even further. In particular, the focus is on extending the range by reducing rolling resistance. In addition to the original tyres, the Conti Effi cientPro and brand-new prototypes are used in direct comparison. The Conti Effi cientPro is a proven product that was developed in particular for long- distance transportation and emphasizes fuel effi ciency. Balancing the confl icting goals, especially mileage, braking and handling performance, at an ever-higher level is technically demanding. At the same time, in view of the rapid development of the e-mobility segment, the engineers are in a race against time. Hinnerk Kaiser, head of tyre development - bus and truck tyres, Continental, says: “The tyres for the Futuricum truck are exposed to higher torque during start off and acceleration. At the same time, the weight and weight distribution of the tractor are increased by the particularly powerful battery. Therefore, the tyres must not only have a low rolling resistance but also withstand heavier loads than tyres for comparable vehicles with internal combustion engines. These tyres should last just as long and meet the same safety requirements as truck tyres for conventional drives.” 36 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021 TRUCKSVOLTA TRUCKS STARTS REAL-WORLD TRIALS OF THE VOLTA ZERO V olta Trucks has started the engineering evaluation and development testing of the fi rst prototype Volta Zero at Horiba Mira in Nuneaton, UK. The start of testing follows soon after the reveal of the fi rst prototype chassis of the Volta Zero, a purpose-built full- electric 16-tonne commercial vehicle designed specifi cally for inner city logistics. Named ‘Volta Minus One’ by development engineers, as the forerunner to the production- specifi cation Volta Zero, the prototype vehicle uses the proposed production specifi cation chassis frame and drivetrain of the fi nished vehicle and will test all the electro-mechanical and thermal properties of the truck. This includes the high-voltage battery supplied by Proterra, and the compact rear axle, electric motor and transmission eAxle unit from Meritor. The unconventional bodywork of the prototype is purely designed to protect the development driver from the elements when the vehicle is moving at speed. The production vehicle will feature a cargo box design, but the prototype uses a fl atbed to allow engineers to add diff erent levels and locations of loads to test its weight carrying capacity. The prototype Volta Zero will continue testing at Horiba Mira over the coming months. The forthcoming test and development programme with this and later- specifi cation prototypes also includes periods of cold weather testing north of the Arctic Circle, and hot weather testing in southern Europe. The comprehensive programme will ensure that the production-specifi cation Volta Zero vehicles deliver the durability and reliability expected by fl eet operators and vehicle owners. These learnings will be taken into the production of pilot fl eet vehicles that will be tested and evaluated by key customers who have signed up for both testing and the option to purchase series production trucks. This is designed to develop their understanding of how the Volta Zero will integrate into their operations. Full-scale production of customer- specifi cation vehicles will then follow at the end of 2022. Ian Collins, chief product offi cer of Volta Trucks, said; “The start of testing and evaluation of the fi rst prototype Volta Zero is a major milestone on our journey towards production. To have achieved this landmark moment in just eight months is a great example of the nimble and agile approach we have at Volta Trucks. We work at high pace to ensure that we can bring zero emission, full- electric commercial vehicles to market quickly, because our customers require vehicles as soon as possible. We need to go through a comprehensive and thorough development programme, but the start of prototype testing is evidence that we are on track to deliver production vehicles, on time, by the end of next year.” 37 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021 TRUCKS120HT’s gross vehicle weight coupled with an increased rating on the front steering axles to 26,000 lbs each.

The four axle 120HT features a new, wider single occupant cab that refl ects design elements of the 175AT all-terrain crane. The 120HT also comes with an all-new air ride suspension design, the fi rst-of-its-kind for truck crane buyers. Its suspension and braking system is a result of a two-year collaborative design process with suspension manufacturer Hendrickson International. Air disc brakes, another fi rst for the hydraulic truck crane market, will improve brake performance and reduce maintenance time. The counterweight payload increases from 16,000 lbs (7 257 kg) on the HTC-86110 to 20,500 lbs (9 268 kg) on the new 120HT without a boom dolly. The full counterweight for the 120HT is 49,100 lbs (22 271 kg). The increased counterweight payload is a result of a strategic design approach to reduce the to control outriggers, outrigger beams and jacks, boom hoist, and winches make setup quicker and easier with increased effi ciency. The new operator’s cab comes with a wide- entry access and egress, USB and 12-volt power supply, and increased storage with interior lighting. Pulse 2.0 with its 10 in. (25.4 cm) touch display is at the heart of this crane with features and controls that are intuitive, adaptable, and in easy arm’s reach. The view from the seat is uninhibited in all kinds of weather with large sweeping wipers in the front and top, and strategically-placed vents for fast-acting defrost. Additional features include Link-Belt’s ‘Smart Stack’ counterweight detection system; Link-Belt Pulse 2.0 with improved carrier diagnostics, monitoring, and display of real-time outrigger jack ground bearing pressures; Link-Belt Site Vision (includes camera and working lights package); V-CALC with 81 outrigger positions; and iCraneTrax for better fl eet management. 38 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021 LIFTING AND ACCESS EQUIPMENT LINK-BELT TO LAUNCH 120-TON HYDRAULIC TRUCK CRANE 39 PLANT / MACHINERY / VEHICLESwww.plantmachineryvehicles.comSEPTEMBER 2021 LIFTING AND ACCESS EQUIPMENT Oslo University Hospitals.
