PW220-7 Komatsu Excavator Specs & Dimensions - (2002 - 2007)

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.

Walk-Around

The PW220-7 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.

Improved Fuel Consumption

With its newly developed Komatsu ECOT3 engine, the PW220-7 significantly reduces hourly fuel consumption through highly efficient techniques for matching the engine and hydraulic unit. The Komatsu SAA6D107E-1 engine meets EPA Tier III, and EU Stage IIIA emissions regulations and reduces NOx emissions.

Easy Maintenance

Komatsu designed the PW220-7 to have easy service access. By doing this, routine maintenance and servicing are less likely to be skipped. This can mean a reduction in costly downtime later on. Here are some of the many service features found on the PW220-7: Easy access to the engine oil filter and fuel drain valve. The engine oil filter and fuel drain valve are mounted remotely to improve accessibility. 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. Water separator. This is standard equipment which removes any water that has become mixed with the fuel, preventing fuel system damage.

Attachments commonality & functionality

The stabilizer and dozer blade are interchangeable, and therefore can be attached on the front or rear of the chassis. The stabilizer and dozer blade are controllable from the monitor panel. The monitor panel has four buttons that allow individual attachment operation as well as collective operation.

Advanced Attachment Control

The PW220-7 is 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 Attachment piping options for breaker, clamshell or crusher

Four Working Modes

The PW220-7 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.

SpaceCab™

Sealed and pressurised cab with standard climate control Low-noise design Low-vibration design with viscous cabin damper mounting Cab moved forward for better visibility Ergonomic control levers Seat specially designed for wheeled machines, with exceptional extra comfort. The new PW220-7 inner cab volume is 14% greater than the Dash 6 models, offering an exceptionally comfortable operating environment. The large cab enables the seat, with headrest, to be reclined to horizontal.

Pressurised cab

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

Cab damper mounting for low vibration levels

PW220-7 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.

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%.

Power mode

For maximum power and fast cycle times. Normally used for heavy operations such as hard digging and loading. This mode allows access to the 'PowerMax' function to temporarily increase the digging force by 7% for added power in tough situations.

Outriggers

Independently controlled outriggers are optionally available on both, the front and rear of the machine. The cylinder protections are standard on the outriggers.

Safe and precise lifting

PW220-7’s stability is one of the best in its class. The machine is equipped with boom safety valves and overload caution as standard. This combined with the control of HydrauMind and the power of the lifting mode, gives incredible safe and precise lifting performance. Example: The over-front lifting capacity (reach 6,0 m over front, height 1,5 m) is 9,1 tonnes (outriggers front + rear, mono boom with 2,4 m arm and bucket).

PowerMax function

PowerMax can be selected by depressing a joystick button for an instant burst of power to help break through tough digging situations. The PowerMax function is available in the P and E working mode.

Two-Piece Boom

When removing bucket, linkage or cylinder, lifting capacities can be increased by their respective weights. Load is limited by hydraulic capacity rather than tipping. Ratings are based on SAE Standard No. J1097. Rated loads do not exceed 87% of hydraulic lift capacity or 75% of tipping load.
