Artic offers more than an engine update
It’s one thing to fulfill a mandate to meet emissions requirements. True to form, however, Komatsu has used the opportunity to enhance the performance and productivity of its HM400-3 articulated dump truck. Powered by a Tier 4 Interim-certified SAA6D140E-6 engine generating 469 horsepower, the new 40-metric-ton-capacity artic has an updated body design that increases payload. In load-and-haul applications, the truck’s low loading height of 10 feet 5 inches matches easily with 40- to 60-metric-ton hydraulic excavators or 5.5- to 6.5-cubic-yard wheel loaders. Two single-staged body lift cylinders provide the truck with a 70-degree dump angle. The new Komatsu Traction Control System (K-TCS) automatically provides optimum traction when operating in soft ground conditions. As ground conditions worsen, speed sensors located on four wheels detect tire slippage, and automatic application of the inter-axle differential lock occurs. If tire slippage continues to be detected, four independent brakes can be applied to slipping wheels to regain traction. The HM400-3’s six-speed, fully-automatic transmission uses an advanced electronic system to eliminate shift shock and torque cutoff.
Keeping those big trucks rolling
When it comes to heavy hauling, rubber is gold. Keeping good tires under big iron is essential to quarries operating at optimum 24/7 productivity. To that end, the Michelin X-QUARRY S tire features a square, reinforced shoulder providing a large contact area, resulting in even tire wear. A thick sidewall band protects the rigid-dump-truck tire from abrasions and damage caused by rocks or other site debris. The tire’s non-directional tread is unbroken in the center – with deep, angled grooves – to reduce vibration and enhance the ride comfort for the operator. Easy to repair, the X Quarry S tire has low rolling resistance, increasing the fuel efficiency of the truck, says Michelin.
Free help for your material calculating needs
Just not quite sure how much asphalt, stone or brick you’ll need for this job? Well, just reach for your phone. A new free mobile app from Graniterock enables Apple iPhone and iPod Touch users to access a broad range of construction materials calculators. The Graniterock Construction Calculator app helps engineers quickly estimate the amounts of material required, by accessing processors categorized under: Unit Conversion, Concrete Materials, Aggregate, Road Materials, Masonry Estimator and Mulch. Plans were for this tool, downloaded from Apple’s AppStore, to also be available for iPad and Android.
Electric-powered push sprayer
The SnowEx SL-80 and SL-80SS push sprayers for ice management on sidewalks and other small areas are completely electric-powered. Available with a powder-coated steel frame (SL-80) or stainless steel frame (SL-80SS), both sprayers have a 12-gallon, corrosion-resistant polyethylene tank. Each model includes an adjustable-height boomless nozzle, which sprays most salt brine and liquid ice melters up to 48 inches wide. The units also come with an adjustable spray wand for spot-spraying applications. A 12-volt electric pump and rechargeable battery powers the SL-80 and SL-80SS. The pump is rated at 2 gpm at 60 psi.
Portable generator with digital control system
The Atlas Copco QAS 45 portable generator features a Kubota Tier 4 Interim diesel engine and a Leroy Somer, LSA Model, series alternator, enabling it to deliver 35 kW of prime power. The QAS 45 generator includes a standard multi-voltage selector switch and QC1002 digital control system. The instrument panel enables all key operating functions to be managed without opening the canopy. A 70-gallon fuel tank is expected to allow a 24-hour run time. Designed for extreme weather conditions, the generator features a Zincor steel enclosure and its frame is designed to be spillage-free to protect the environment. Options available include a battery charger and battery switch, a coolant heater and a wireless remote start. Extended warranties are also available.
Automatically shuts down non-essential loads
Cole Hersee’s FlexMod LVD configurable electronic module ensures that vehicles start by controlling non-essential loads that can kill a battery. The module is ideal for those with fleets of emergency vehicles, delivery vehicles, boats, buses or utility trucks. The FlexMod LVD automatically shuts down non-essential loads when the battery runs low, and automatically restores the non-essential loads when the battery power returns to normal levels. Typical applications include idle reduction for work vehicles, NFPA 1901 Load Manager compliance for fire vehicles, combined timer/voltage shutoff for police vehicles and smart charging system for boats. The FlexMod family has two inputs (one analog, one digital) and two solid-state outputs (one 10A, one 200mA) that can be programmed to do almost any job, according to the manufacturer.
