AGGREGATES MANAGER November 2015 10 Two new hydraulic excavators Komatsu America Corp has two new hydraulic excavators with swing booms and convex sliding doors, as well as a tight tail swing radius for tight spaces. The PC45MR-5 and PC55MR-5 both come with a 2.19-liter, 38-horsepower, EPA Tier 4 Final, 4D88E07 engine with 5 percent less few consumption and no loss to the power. The excavators also have enhanced working modes, a high-strength X-track frame to keep dirt and debris from building up, a tilt-up cab, and the KOMTRAX telematics system. Komatsu America Corp. | www.komatsuamerica.com An all-around tunneling jumbo Sandvik Construction's DT922i tunneling jumbo comes with a new articu- lated carrier, a next generation cabin and a reduced noise level. Sandvik says the state-of-the-art control system and the new iSURE excavation management tool on the DT922i would "change the future" of tunneling. The machine is a fully-automated, electro-hydraulic, two-boom tunneling jumbo designed for excavating cross sections up to 1,345 square feet with face drilling, bolt hole drilling, and long hole drilling. The new articulated carrier lets the jumbo operate in tight quarters with narrow corners with better visibility than previous models. The RD525 rock drill on the DT922i has 17 percent higher penetration rates and 40 percent longer tool life for the shank. Each model comes standard with the Tier 3 diesel engine, but a Tier 4 Final engine is optional. Sandvik Construction | www.sandvik.com ROLLOUTS Hit the road with: collect them all!
