Cummins Biggest-Ever Presence At A Construction Show    

LAS VEGAS (March 5, 2014) – Cummins Inc. (NYSE: CMI) announced today that CONEXPO 2014 represents the biggest-ever presence by the company at a construction equipment show, with a cumulative total of over 40,000 hp (29,828 kW) installed in more than 180 machines and vehicles on display. The lineup of Cummins power includes the first appearance of the compact QSF2.8, and the heavy-duty QSG12, installed in new equipment meeting U.S. Environmental Protection Agency (EPA) Tier 4 Final and European Union (EU) Stage IV regulations.

The Cummins-powered Tier 4 lineup on show extends from some of the smallest to some of the largest equipment, from a 73 hp (55 kW) QSF2.8-powered Tier 4 Final compact carry crane from Manitex, up to the most powerful Tier 4 Interim equipment, with a 990-hp (738 kW) road milling machine introduced to the North American market by Wirtgen, featuring a twin-engine Cummins installation with QSL9 and QSX15 engines.

Always a focus of attention for visitors to CONEXPO are the biggest excavators: high-capacity machines with up to 130-ton operating weights, proudly displayed at the Hyundai and Hitachi booths, each powered by a Cummins QSK23 engine with 760-hp (567 kW) output. The 23-liter displacement provides the deep reserves of strength required for high breakout force at the quarry face or on the mine site. 

“Cummins, together with our joint-venture partners, builds more engines each year for construction and industrial equipment than any other manufacturer. It is no surprise to see  the full breadth of Cummins power installed at CONEXPO across a wide variety of machines,” said Hugh Foden, Executive Director – Cummins Off-Highway Business.

“CONEXPO is the ideal venue to showcase Cummins power capability, and we have more installations here than we have ever had at any show before – reflecting the ability of our Tier 4 technology to transform machine productivity,” added Foden.

Other large equipment with Cummins power includes all-terrain cranes. In those applications, Cummins unique ability to provide both on- and off-highway engines meeting all emissions standards is realized with the ISX15 for travel power, combined with the QSB6.7 as the upper engine for powering the crane. This pairing has the advantage of easier control integration, as both engines incorporate the same electronic control system and interface.   

Innovative QSG12 First Installation On Show
A highlight at CONEXPO is the first installed appearance of the QSG12 heavy-duty engine in a large, new crawler crane. Announced less than a year ago, the 12-liter Tier 4 Final engine has already attracted significant attention from original equipment manufacturers (OEMs) due to its remarkably compact size and low weight, achieving a high 510-hp (380 kW) output. The QSG12 does not require a cooled Exhaust Gas Recirculation (EGR) system to meet the Tier 4 Final emissions standards, so cooling requirements remain similar to those of a Tier 3 engine.

The QSG12 is 660 to 880 lb (300 to 400 kg) lighter than other engines in its class, due to an innovative use of composite materials and a sculptured block that reduces unnecessary mass while maintaining structural rigidity.   

The QSG12 is also featured at CONEXPO as part of a diesel-hybrid powertrain revealed by Oerlikon Fairfield, configured for a 30-ton wheel-loader application. The engine runs at a 1200-rpm “sweet spot,” to contribute to a 25 percent to 30 percent savings in fuel consumption. The hybrid system is able to eliminate all electric auxiliary drives, and offers a seamless stop-start capability for the engine.
