Komatsu America Corp. has introduced the PC360LC-11 hydraulic excavator. With a net horsepower of 257 hp. (192 kW), the PC360LC-11 is powered by a Komatsu SAA6D114E-6 engine, which is EPA Tier 4 Final emissions certified. Komatsu's Tier 4 Final engines are built on the foundation that started in 1996 with the introduction of Komatsu's first Tier 1 engine. This new excavator leverages Komatsu's leadership in technology and innovation by delivering a more environmentally friendly engine that provides high levels of performance while reducing operating costs and improving fuel efficiency.
With an operating weight between 78,645 lbs. (35,627 kg) and 80,547 lbs. (36,535 kg), the PC360LC-11 has upgraded cab features and an enhanced power mode for greater productivity and lower cost per ton. The excavator is equipped with the latest KOMTRAX technology, which relays data such as fuel levels, Diesel Exhaust Fluid (DEF) levels, operating hours, location, cautions and maintenance alerts. A new Operator Identification System reports key operating information for multiple operators, and the new Auto Idle Shutdown function helps reduce idle time as well as operating costs.
Komatsu EPA Tier 4 Final Emission Certified Engine – Productive, Dependable, Efficient
Komatsu's proven Tier 4 Interim foundation integrates a Selective Catalyst Reduction (SCR) system using DEF to meet EPA Tier 4 Final emission regulations for NOx emissions. The engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability, according to the company. Komatsu continues to use its Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve for precise temperature and air management control as well as longer component life.
For reliability and durability in demanding conditions, Komatsu developed the entire system, including the control software that is critical to the effective operation of the aftertreatment system. Additionally, the control system is integrated into the machine's on-board diagnostics systems and KOMTRAX, Komatsu's standard telematics system.
Highly Efficient Hydraulic System
All major components on the new PC360LC-11 including the engine, hydraulic pumps, motors, and valves are exclusively designed and produced by Komatsu. This integrated design uses an efficient closed center load sensing hydraulic system and features a new enhanced power mode for improved performance and reduced cycle times.
Operator Environment
The PC360LC-11 cab provides a more comfortable and quieter work environment. The ISO 12117-2 ROPS certified cab, specifically designed for hydraulic excavators, gains strength from a reinforced box structure framework. The cab is mounted on viscous isolation dampers that provide low vibration levels. A standard heated air suspension high back seat with new fully adjustable armrests provides improved comfort. In addition to the standard AM/FM stereo radio, a remote located auxiliary input for connecting external devices is provided to play music through the cab speakers. Additionally there are two 12-volt power ports incorporated into the cab, and optional joysticks are available with proportional controls for attachment operation.
For global support, the high-resolution 7" LCD color monitor features enhanced capabilities and displays information in 33 languages. The operator can easily select up to six working modes to match machine performance to the application. The monitor panel provides information on DEF fluid level, Eco guidance, operational records, fuel consumption history, and utilization information. A new display interface combines vehicle information with a wide landscape view from the standard rearview camera so the operator can easily view the working area directly behind the machine.
Convenient Maintenance and Serviceability
The PC360LC-11 has handrails on both sides of the upper structure for easy accessibility and service access. A large 10.3-gallon (39 liter) refill capacity DEF tank is located in a lockable compartment directly behind the right side toolbox, and is sized to provide a 2:1 diesel to DEF refill ratio. Side-by-side radiator and hydraulic oil coolers make it easy to maintain and service the machine.
The new excavator is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which has enhanced diagnostic features to give the operator and technicians greater monitoring and troubleshooting capabilities for preventative maintenance, minimizing diagnostic and repair time.
