Trimble has acquired privately held Gatewing of Gent, Belgium, a provider of lightweight unmanned aerial vehicles (UAV) for photogrammetry and rapid terrain mapping applications. UAVs provide users the ability to create orthophotos and Digital Surface Models (DSM) from aerial imagery for mid-sized areas previously only accessible at higher costs and with longer planning cycles. UAVs are used in a variety of applications including preliminary surveys for corridors and rights-of-way, volumetric surveys, high-level topographic surveys, and landfill inspection. Gatewing’s solutions include the X100 UAV and Stretchout desktop software for digital image processing and analysis. The X100 is an ultralight, a 4.4-pound-class UAV that allows fast and simple image acquisition. It consists of an airframe, an integrated GPS, inertial system and a radio; a 10-megapixel camera; and battery. Using the Trimble Yuma tablet computer, a predefined area is planned and the flight of the UAV is fully automated from launch to landing.
Greenhouse gas calculator
The National Asphalt Pavement Association (NAPA) has expanded its online Greenhouse Gas Calculator that can be accessed at asphaltpavement.org/ghgc. The calculator compares emissions associated with various fuels used to dry aggregate, plus fuels used by facility equipment, including vehicles CO2e attributed to electrical use. The calculator includes emission offset credits for fuels and activities that reduce the amount of CO2e released or that sequester CO2. Credits are calculated for plant-based biofuels, recycled fuel oil, and recycled raw materials, such as reclaimed asphalt pavement and recycled asphalt shingles. Credits are also calculated for reducing mix temperatures using warm-mix asphalt technologies.
GOMACO’s rear-loading, front-inserting 5400 Series bar inserter is now available on its 3100 and 5000 Series molds with a self-supported transition adjustor. Previously, the 5400 bar inserter was only available with the 5400 Series mold. The inserter mounts to a T-bar at the front of the 3100 or 5000 Series mold, while the bar loading chain system is supported by a stand in the rear of the mold. It can be retrofitted to any existing 3100 or 5000 Series mold in the field with a self-supported transition adjustor. On-the-go crown changes can be made while still maintaining constant bar depth during insertion. Individual guides on the right and left side of the bar inserter keep each bar parallel to the top of the slab while smart cylinders control the depth of each bar’s placement. The GOMACO exclusive G+ control system is used to control the bar insertion process and timing.
Bergkamp’s M212 truck-mounted slurry seal and microsurfacing paver carry 12 cubic yards of aggregate in a level struck load, 691 gallons of asphalt emulsion and 691 gallons of water and features a 65-gallon stainless steel additive tank. The pugmill, conveyor and all-liquid material tanks are removable for easy cleaning. All tanks are bolted in rather than welded. Asphalt emulsion and water tanks are separate components, which eliminates possible rust-through and contamination of products. The M212 has a full-width working platform so operators can see both sides of the unit, the spreader box and the material being placed. A remote sideshift control lets the spreader box operator control the box from the ground.
TVR with dual travel levers
The new BOMAG BW138AD-5 tandem vibratory roller features dual travel levers and Smart Drive steering wheel, a foldable ROPS and larger drum diameter. The machine is also equipped with a pressure water sprinkler system with a high-capacity 81.9-gallon water tank for extended operation intervals between refills. A Tier 4i 44.6-horsepower, water-cooled Kubota diesel delivers a maximum centrifugal force of 10,800 pounds. With a working width of 54.3 inches, the roller includes larger 35.4-inch-diameter drums and provides dual vibration frequencies of 3,480 or 2,820 vpm. The roller’s bolt-on oscillating and articulating joint enables the rear drum to follow the same path as the front drum while turning.
Chicago Pneumatic has updated its line of medium- (BRK 55 HBP), heavy- (BRK 70 HBP) and super-heavy-duty (BRK 95) high-back pressure (HBP) breakers to accept the higher return pressure found on skid steers. Able to accept up to 515 psi (35 bar) of back pressure, their high pressure tolerance also permits the use of much longer hoses on job sites where space and access can be an issue. The BRK 55 HBP works with both 8 gpm and 5 gpm power packs. The BRK 70 HBP breakers are ideal for heavier demolition jobs, and are suitable for use on tough materials such as asphalt, frozen soil, and reinforced concrete, says the maker.
Miller Electric’s Multimatic 200 all-in-one portable multi-process welding power source does MIG, Stick and TIG welding processes in one compact design. The new Auto-Set Elite feature allows operators to quickly and easily set weld parameters based on material type and thickness, as well as fine-tune those parameters to match each specific application. The system has an impact-resistant polycarbonate case, weighs 29 pounds and connects to common 120- and 230-volt power receptacles with the Miller-exclusive MVP multi-voltage plug. Similar to the Millermatic Passport Plus, the machine offers positive arc starts and a stable arc with minimal spatter when MIG welding – with mixed gases and straight CO2.
