Concrete Grinder: Can Also Do Finishing
The Hilti DGH130 concrete grinder can be used for either grinding or finishing concrete. It has a maximum rpm of 8,700 and accepts standard 5-in. discs. For grinding, the DGH130 uses diamond cup wheels and has an adjustable hood with a cutout for grinding against edges and corners. For finishing, the DGH130 can use Hilti’s diamond finishing pads. An integrated dust hood and vacuum port keeps the tool compliant with OSHA regulations on silica-dust exposure. Hilti; www.us.hilti.com
Concrete Floor Treatment: Newly Reformulated
The MCI POWR 100 concrete surface treatment has been reformulated to better repel water, protect against corrosion and provide oil and stain resistance for concrete flooring. In tests conducted by the manufacturer, the treatment was found to perform as well as or better than silane-based sealants in water and oil resistance, and showed resistance to pooling oil for two to three weeks of exposure. The single-component treatment is meant for use with concrete surfaces regularly exposed to oil, grease or water, including parking garages and industrial settings. Cortec; www.cortecvci.com
Hydraulic Excavator: 3D Machine Controls
The PC290LCi-11 excavator features Komatsu’s iMC intelligent machine control system, with integrated sensors in the boom, bucket and hydraulics. This system can work with 3D design data to keep the excavator on task and significantly reduce over-excavation and rework. It features automatic grade assist to adjust the bucket and boom as the operator moves the stick to fit the preset 3D design, and automatic stop control to prevent the bucket from moving when it reaches the edge of the design surface. The excavator is powered by a 6.69-liter, 196-hp engine that meets Tier 4 Final emissions standards. Komatsu America; www.komatsuamerica.com
