SERVICE AND SUPPORTSeal in Some Extra MileageExtending the life of pavement is easy and affordable with a slurrymicrosurfacing machineRoadways and parking lots that are in reasonablygood shape can receive a new leaseon life with the help of asphalt rubber emulsionslurry seal machines built by VSSMacropaver, a division of Reed Internationalof Hickman, Calf.Adding slurry seal to roadway surfaceswill extend the life of the primary pavementsurface by five to 10 years, according toBill Holmes, engineering manager for VSSMacropaver. Although slurry seal mircosurfacingtechnology has been around fordecades, it has been gaining strong acceptancein recent years. Demand for VSSMacropaver machines are especially strongin China, where investments are being madeto improve the country’s road infrastructure.VSS Macropavers are gaining worldwidedemand, in part, because of their high levelsof productivity. The company manufacturesthree models, each with application rates thatare among the highest in the industry.“Contractors are paid by the square foot oryard,” explains Holmes. “The more they layin a day, the more money they make.”Since the mid-1990s, VSS Macropavershas built its slurry seal machines withJohn Deere diesel engines, each fitted witha John Deere triple-pad Funk pump drive.The first product to be designed with aJohn Deere engines was the Minimac, a oneman,self-propelled machine used to applyslurry and polymer-modified microsurfacingmaterials to confined areas such as parkinglots, garage structures, footpaths, walkways,and bicycle trails. Powered by a 115-hp4045T Tier 2 industrial engine, the Minimacoutputs of up to 900 kg/min (1 ton/min),making it very productive for a small, goanywhere machine.A modified version of the Minimac is CR-1000. Powered by a 140-hp, air-to-air aftercooled4045H engine, this machine has thecapability and endurance to “load on the go,”making it ideal for long, continuous runs,such as roads and highways.Perhaps the darling of the VSS line is theMacropaver 12B. Powered by the 115-hp4045T, this machine’s productivity is a robust2,700 to 3,600 kg/min (3 to 4 tons/min),making it up t o twice a productive as competitivemodels. It’s automatic sequencingfeatures, pioneered and perfected by VSS,enhances the machine’s performance.Aside from boosting productivity, VSSchose John Deere engines for their smoothand quiet operation. “Coming from anothercompany where I always had to use isolationmounts on the engines, I found that we couldhard mount the John Deere engines directlyto the frame without any issues with vibrationor noise.”In fact, VSS incorporates a trio ofJohn Deere engines on its Asphalt RubberEquipment. This three-component system isdesigned to mix recycled tire rubber with liquidasphalt oil, creating an asphalt rubberbinder that enhances the strength and durabilityof asphalt. This trailer-mounted unitsfeature a heater/blender vessel and a reactionvessel, each powered by its own John Deere4045H engine, as well as an electric-poweredrubber feed unit, powered by a John Deerepowered gen-set, a component outsourcedfrom Multiquip, a company that is also along-time customer of John Deere engines.As VSS expands its global presence, thecompany will look to John Deere to provideservice and support to its international customerbase. “There are a plethora of JohnDeere dealers, and that network of supportcontinues to improve internationally,” statesHolmes. “On the flip side, we have very fewThe Macropaver 12B mixes a slurry seal ofasphalt emulsion, crushed aggregate, water,and a liquid or dry additive, which is appliedto the pavement surface.problems with John Deere engines, and veryfew after market problems or warrantyissues.”Engines: John Deere PowerTech 4045T –115 hp, 4-cylinder, 4.5 L, turbochargeddiesel engine; PowerTech 4045H – a 140 hp,4-cylinder, 4.5 L, air-to-air aftercooled dieselengine.Pump drive: Funk Series 28000, directengine mount; with a 1:1 gear-ratio drive;three-pad pump drive.Distributor: Western Power Products,Inc., Woodland, Calif., (530) 666-6624.www.westernpowerproducts.net14 PowerSource
SERVICE AND SUPPORTWALO crews widen the Rifa equalizing reservoir in Partenen,Austria. The asphalt seal is applied directly onto the substratelaid by the contractor.Powerful Solutionsfor an Uphill BattleA Swiss construction company creates one-of-a-kindJohn Deere-powered winches to stabilize its pavers androllers that work on steep slopesSo why John Deere engines? “Our mechanical engineer comparedspecs and quotes, and John Deere came up best on both counts, as wellas on delivery time and quality. We bill all our jobs by the hour, so wehave to keep production up at all times even in remote places, and someof our jobs are very remote. We feel confident that John Deere willcome through with the 24-hour / 7 day-a-week service it offers, becauseit has the network to back this up.”“For the power winches, we only needed to make a few slightmechanical adjustments to the engines to fit our specific needs, and sofar we’ve been pleased with their performance.”Sometimes your business is so specialized that no one has the rightmachines, and you simply have to build them yourself. In such cases,John Deere engines can be an enormous help, as the Swiss constructioncompany WALO Bertschinger has discovered.Versatility in construction. Growing its business since 1917, thisversatile company has a dozen divisions handling everything frombuildings, roads and civil-engineering infrastructure to industrial anddecorative flooring. A prime area of expertise for them, though, isbituminous asphalt seals. One of WALO’s civil engineers explains:“As a pioneer in this area, we’re called in on projects all over theworld to build or renovate dams, reservoirs, pumped storage, andequalizing reservoirs, as well as to build canals, artificial lakes, andirrigation systems for agriculture.”With ever more stringent environmental requirements, adequatesealing is essential. Some customers request absolute waterproofing,which only an asphalt system will satisfy; concrete is simply not anoption. At other times, asphalt’s fast lining process makes it thematerial of choice. WALO Bertschinger’s engineers bring ingenuityand experience to bear in finding and implementing solutions to thetrickiest problems.The right machine for the job. The complex jobs WALOBertschinger takes on often require special equipment. The WALOspokesman continues: “Different aspects of our construction projectsfrequently call for very specific machine capabilities that just can’t befound on the market. So we anticipate these needs and integrate theminto our planning right from the start. There is a lot of competition inthe construction industry, but only a company like ours, with extensiveengineering skills in-house, along with a strong financial base to coverinvestments, can handle this type of business. It’s a niche market notevery company wants to enter.“For a recent job we built two winches for asphalting slopes, supportingthe pavers and the rollers. One of them weighs 35 tons, the other 65tons. They’ve meanwhile become an integral part of our business andare being used worldwide in all our asphalt lining projects. Togetherwith the experience and know-how of our crews, they are a key assetfor our business. For projects like power plants, we’re under constantpressure to reduce construction time. By creating machines like these,we can improve our performance.”The winches provide stabilization to thepavers and rollers, enhancing efficiencyand productivity.WALO’s customer base includes electric power producers and landfilloperation companies, but also municipalities and even ski resorts.These resorts build reservoirs to collect water during the summer,which they then turn into artificial snow should the real thing fail toarrive in winter.So wherever a reservoir is needed, you may well see WALO and itscustom-made machines in action.Engine: John Deere PowerTech 6125H – a 298 kW (400 hp),6-cylinder, 12.5 L, air-to-air aftercooled diesel engine.Distributor: Hamilton AG, Brüttisellen, Switzerland;Tel. +41 44 805 2080; Fax. +41 44 805 2085;email: douglas@hamilton-ag.ch; web: www.hamilton-ag.chPowerSource 15
