PC340LC-7 Komatsu excavator specs & Dimensions (2002 - 2005)

SpaceCab™

The new PC340-7’s cabin space has been increased by 14%, offering an exceptionally-roomy operating environment. Sealed and pressurised cab with standard air conditioning Low-noise design Low-vibration design with cabin damper mounting OPG Level I (ISO) compliant cabin The new PC340-7 inner cab volume is 14% greater than the Dash 6, offering an exceptionally comfortable operating environment. The large cab enables the seat, with headrest, to be reclined to horizontal.

Cab damper mounting for low vibration levels

PC340-7 uses a new and improved viscous damping cab mount system that incorporates a longer stroke plus an added spring. The new cab damper mounting, combined with strengthened left and right-side decks, aids the reduction of vibrations to the operator’s seat. Vibrations at the floor level have been reduced from 120 dB (VL) to 115 dB (VL).

Walk-Around

The PC340-7 is a rugged, productive, all-European machine. Designed and expressly built for European markets, it delivers productivity, reliability and operator comforts in a robust, environmentally-friendly package. Komatsu’s exclusive, on-board, HydrauMind system assists in all operations, providing enhanced machine performance that’s always perfectly matched to the task.

Economy mode

The environmentally-friendly mode. For running more quietly during operations at night and/or in urban areas. Fuel consumption and exhaust emissions are reduced. ‘Economy’ mode meets the needs of the 21st century. This mode offers the user fuel savings, quiet operation, and less emissions.

Password protection

Prevents unauthorised machine use or transport. The engine cannot be started without your four-digit use or password. For total security, the battery is connected directly to the starter motor. Both the starter and the engine need the password. The password can be activated and deactivated upon request.

Engine

The PC340-7 gets its exceptional power and work capacity from a Komatsu SAA6D114E-3 engine. Its output is 184 kW/247 HP, providing increased hydraulic power and improved fuel efficiency.

Reliable components

All of the major machine components, such as the engine, hydraulic pump, hydraulic motor and control valves, are designed and manufactured by Komatsu. This guarantees that each component is expressly built for the class and model of machine. This ensures that the engineering, manufacturing standards and testing that go into each component are ‘totally-Komatsu’.

Low noise

Noise has been reduced from the engine as well as from swing and hydraulic operations. The dynamic noise level is just 75 dB(A) at operator ear level (ISO 6369).

Four working modes

The PC340-7 is equipped with three working modes: (P, E, B), plus a lifting mode (L). Each mode is designed to match the engine speed, pump speed, and system pressure with the current operating requirement. This provides the flexibility to match equipment performance to the job at hand.

Fingertip hydraulic pump oil flow adjustment

From the LCD monitor, you can automatically select the optimal hydraulic pump oil flow for breaking, crushing, and other operations in the B, P or E modes. Also, when simultaneously operating with attachments and work equipment, the flow to the attachment is reduced automatically, thus delivering a smooth movement of the work equipment.

Hydraulics

The unique two-pump system ensures smooth, simultaneous movement of the work equipment. Komatsu’s exclusive HydrauMind system controls both of the pumps for most-efficient use of engine power. The system also reduces hydraulic loss during operations. Optional, additional hydraulic circuits may be ordered.

Easy end-of-life recycling

The PC340-7 is designed with the consideration of end-of-life recycling, effectively reducing its environmental impact. All exterior parts are made of steel. Extended engine oil, hydraulic oil and filter replacement intervals reduce environmental impact. All plastic parts are given a material code symbol.

Displays running conditions and abnormality indications

At the operator’s fingertips: the VHMS controller monitors engine oil level, cooling water level, fuel level, engine water temperature, engine oil pressure, battery charging level, air filter clogging, and more. The monitor also indicates whenever abnormalities are detected.

VHMS ‘real time monitoring system’

The ‘real time monitoring system’ displays up to four different operating parameters simultaneously, giving the mechanic a total overview for faster troubleshooting. Parameters include operating conditions such as hydraulic oil pressure, engine RPMs, various voltages and currents, and even temperature measurement.

Side-by-side cooling

The oil cooler and radiator are installed side by side. As a result, it is very easy to clean the radiator, etc. In addition, the operator can remove and install the aftercooler, radiator and oil cooler in a short time.

Advanced Attachment Control

The PC340-7 can be optionally equipped to handle a wide variety of attachments. The advanced attachment control system features: Operator selectable hydraulic flow control Adjustable presets for rapid attachment changeover Additional filters and accumulators for attachment and machine protection Hydraulic relief pressure control Automatic changeover valves Attachment piping options

Pressurised Cab

The standard-equipped climate control, air filter and a higher internal air pressure resist dust entry into the cab.

Multi-position Controls

The multi-position, proportional pressure control levers allow the operator to work in comfort whilst maintaining precise control. A double-slide mechanism allows the seat and controllers to move together, or independently, allowing the operator to position the controllers for maximum productivity and comfort.

Improved Wide Visibility

The right side window pillar has been removed and the rear pillar reshaped to provide greater visibility. Blind spots have been decreased by 34%.

Optional Equipment
