March 7, 2017

The construction equipment manufacturer is introducing two new excavators and a crawler dozer

Construction equipment manufacturer Komatsu today introduced three new machines at CONEXPO/CON-AGG 2017. The newly unveiled machines include the HB3650LC-3 hybrid excavator, the PC170LC-11 hydraulic excavator and the D51 EX/PX-24 crawler dozer. 

"We have a great display this year," said Rich Smith, Komatsu's vice president of products & services. The company is displaying 26 machines in total at CONEXPO, including 10 excavators, seven dozers, four wheel loaders, three dump trucks, a motor grader and a fork lift. 

The HB365LC-3 utilizes a 8.85-liter Komatsu SAA6D114E-6 engine with 269 hp. New performance features include the Komatsu Hybrid System that uses swing energy regeneration and an ultra-capacitor to provide fast energy storage and instantaneous power transmission. The hybrid excavator operates in six working modes to provide a wide range of performance and fuel efficiency. 

The PC170LC-11 features 121 hp and a SAA4D107E-3 engine. The hydraulic excavator also features auto idle and auto idle shutdown systems for reduced fuel consumption. A standard ISO/Backhoe pattern-change valve makes it easy to switch joystick patterns on the machine. Light enough to be transported on a 40,000-lb tag trailer, the machine boasts an enhanced power mode for up to 6% more productivity.

The D51 EX/PX-24, said to be one of the most versatile among all Komatsu dozers, features an electronically controlled hydrostatic transmission. Boasted to be 15% more productive and 13% more fuel efficient, the crawler dozer features the new PX model high-capacity blade with wear-resistant moldboards. The machine includes a 4.5-liter, 131-hp SAA4D107E-7 engine, which achieves higher fuel efficiency with the addition of Selective Catalytic Reduction (SCR) and Diesel Exhaust Fluid (DEF) tank.

Smith detailed some of the work that Komatsu has done with SMARTCONSTRUCTION, mentioning that the company has approximately 1,500 intelligent machine controlled units whose owners are taking advantage of SMARTCONSTRUCTION technology, which connects all jobsite information involved in construction in all phases from pre-construction to completion. "Working together with Komatsu distributors, SMARTCONSTRUCTION allows customers to stay on top of the latest technology and best practices," Smith said. "We envision SMARTCONSTRUCTION as being the true jobsite-of-the-future solution." 

Smith also highlighted the services provided by Komatsu's customer portal The service tool has become a platform for customers to view their fleets as a whole and to see all the service information on each machine in their fleet.
