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.
Caterpillar engines are now standard equipment on Schwing America’s SP-305, SP-750-15 and SP-750-18 stationary concrete pumps. These models with Cat power offer a versatile range of capabilities including shotcrete, grout and concrete pumping. The twin-cylinder, all-hydraulic pumps use exclusive Schwing features to pump concrete with up to 1.5-inch aggregate. Output for the SP-305 is up to 30 cubic yards per hour with up to 625 psi applied to the concrete. The SP 750-15 and 750-18 offer outputs to 70 cubic yards per hour with up to 1,100 psi on the concrete.
Compressor designed for heavy-duty construction
The new Chicago Pneumatic CPS 750 JD7 Tier 4a rotary screw, portable compressor generates 750 CFM of air at 100 psi. This air end has been engineered to reduce the horsepower required to produce the 750 CFM, resulting in better fuel efficiency. Air pressure adjusts from 58 psi up to 100 psi. The electronically controlled, water-cooled engine, variable speed fan, and new air end reduces fuel consumption to 8.2 gallons per hour at 100 percent load, according to the manufacturer. The machine fits cleanly into a single-axle, fast-track enclosure. This new sound-dampening enclosure is more compact than competitively sized compressor packages, according to Chicago Pneumatic.
RoadMix with new EGR system
The new Terex CR662RM RoadMix material transfer vehicle and paver meets Tier 4i (Stage 3B) emissions standards. Offering the same 260-horsepower output as the previous model, the machine’s new EGR power unit is 5-percent more fuel efficient to extend operating intervals between tank refills, according to Terex. A new cooling system arrangement features larger radiator core size and improved airflow to increase ambient operating temperatures to 120 degrees F. To offset increased space requirements of the Tier 4i engine components, Terex engineers developed a new low-profile hood design that slopes downward away from the operator to improve hopper visibility. Components from the paver’s fume recovery system have been moved from underneath the operator’s platform to under the hood, lowering operating noise levels and improving operator comfort.
New powertrain options
Western Star Truck Sales has new powertrain options for all 6900 Model configurations. In addition to the Detroit Diesel DD16, the Detroit Series 60 Tier 3 engine is now available for the Western Star 6900 Twin Steer (TS) truck model. The Series 60 Tier 3 features a single stage turbo and no EGR. The engine’s design also eliminates the need for any kind of regeneration, further enhancing its efficiencies, according to Western Star. The Allison RDS 4500 and 4700 automatic transmissions are also available for the 6900TS. All powertrain options are now available to order.
Weiler E2850 Remixing Transfer Vehicle (RTV) is designed to help improve smoothness and handle large volumes on high-production paving jobs. It is a larger version of the proven E1250A RTV. The machine has working speeds of up 194 feet per minute, even when the hopper is at or near its full capacity of 25 tons. Optional rear steer provides a tight inside turning radius of 14 feet. The steering angle returns to center on demand. A flow divider with a momentary switch provides equal force to the front and rear wheels for enhanced traction when working on uneven terrain. The electronic controller provides instant feedback on hydraulic pressures, ground speed and engine operation. The operating platform hydraulically extends beyond the mainframe from zero to 12 inches in either direction for improved visibility on the right or left sides, making it easier for operators to see and be seen. Three-speed hydrostatic drive powers Cat planetaries for on-the-fly shifting.
Cummins natural gas option
Kenworth Truck Co. is expanding its line of green products by offering the Cummins Westport ISX12 G heavy-duty natural gas engine for use in regional haul, vocational and refuse markets. The new engine requires a single fuel source and can run on either compressed (CNG) or liquefied (LNG) natural gas. The ISX12 G will be available with the Kenworth T660, T800, T800 short hood, and the Kenworth W900S. The engine will come with a range of ratings to 400 horsepower and 1,450 pounds per feet of torque, optional engine brake and manual and automatic transmission capability to meet customer needs, according to Kenworth.
Five technologies for business
The John Deere WorkSight integrated suite of technology solutions for business optimization consists of five technologies including the following: JDLink machine monitoring system, Fleet Care proactive machine health program, Service ADVISOR, Remote dealer diagnostics, grade control, and payload weighing. The JDLink proprietary system provides machine location, utilization measures, and maintenance tracking via a Website. Two service levels are currently available. John Deere also notes, “Keep a lookout for future integration of wheel loader payload data into JDLink.”
