PC350LC-8 Komatsu excavator specs & Dimensions (2007 - 2013)

Walk-Around

The new High Reach Demolition PC350LC and NLC Dash 8 machines have been designed with maximum machine deployment in mind. These machines retain all of the benefits of the Dash 8 excavators and give extra features to ensure that the “High Reach” machine can be more easily used for all of the jobs on a demolition site - and more.

Features for demolition

The work equipment of the Dash 8 High Reach Demolition excavator allows the machine to be used in many different arrangements. Changing from one configuration to the next has never been quicker, maximising the machine up time.

Complete safety

Tubular design developed specifically for hydraulic excavators to protect the operator in the event of a roll over accident.

Fops

The operator guards fitted to the high reach demolition machine are fully tested to ISO 10262 Level 2, enhancing operator safety. The PC350-8 high reach demolition machine carries a hinged type front FOPS guard, allowing easy access for cleaning.

Revolving frame

The revolving frame is made for the High Reach Demolition specification - no modification is carried out after manufacture. The demolition revolving frame includes:Deep section centre beamsBracing in critical areasPreparation for bolted on side guards The special features of the demolition revolving frame ensure that stress levels are similar to the standard excavator, despite the extra weight of the demolition machine. Durability is a key feature.

Demolition first boom

Designed from the outset to suit both excavation duties and demolition work. The demolition first boom is suitable for arduous excavation work, allowing greater deployment of the machine.

Demolition second boom (extension)

This section of work equipment gives the machine exceptional versatility. It is connected between the first boom section and the third, to give the maximum working height of the machine. If required, the second boom section may be removed to give the medium working height. Installation and removal of the second boom section can be done rapidly, due to the quick change system.

Demolition third boom, mid link and arm

To complete the high reach demolition machine, this section has been purposely designed to give durability and safety, while retaining minimal transport height. Safety valves are included on the cylinders operating mid link and arm and the hydraulic tubes and hoses are mounted on the rear of the equipment, minimising risk of damage.

Hydraulically assisted boom connection

The machine features a Komatsu designed hydraulic boom release system. The system allows fast change over from demolition configuration to excavation configuration, maximising operational hours.Hydraulically activated pins, with safety locking platesBanked quick connection system for smaller hydraulic linesQuick release connectors for main hydraulic circuitsEquipment stands for demolition equipment and excavation equipment

Hydraulically activated pins

The pins are fitted with locking plates to ensure security. The main housing of the pins is inside the demolition boom, to offer maximum protection to the housing and hydraulic connections. Oil is fed to the pins on the underside of the boom, to offer maximum protection to the oil supply.

Easy maintenance

Komatsu designed the PC350-8 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 PC350-8:

Low-noise design

The newly designed cab is highly rigid and has excellent sound absorption ability. Thorough improvement of the noise source reduction technology and the use of low-noise engine, hydraulic equipment and air conditioner mean this machine generates very low noise levels, similar to that of a passenger car.

Working modes

Two established work modes are further improved. P mode - Power or work priority mode has low fuel consumption, but fast equipment speed, maximum production and power are maintained. E mode - Economy or fuel priority mode further reduces fuel consumption, but maintains P mode-like working speed for light operations. You can select Power or Economy modes using a one-touch operation on the monitor panel depending on workload.

Eco-gauge assists energy-saving operations

The Eco-gauge can be seen on the right hand side of the monitor. Working within the green range for environmentally friendly, energy-saving operations reduces CO2 emissions and fuel consumption.

Idle caution

To prevent unnecessary fuel consumption, an idling caution is displayed on the monitor if the engine idles for 5 minutes or more.

Auto-deceleration

The auto-deceleration can be activated by a switch on the monitor. If the control levers and the foot pedals are in neutral position, the engine speed is automatically lowered to reduce fuel consumption. Using the auto-deceleration function can save up to 40% fuel.

New ECOT3 engine

With its newly developed Komatsu ECOT3 engine, the PC350-8 significantly reduces hourly fuel consumption through highly efficient techniques for matching the engine and hydraulic unit. It also includes a number of features to promote energy-saving operation such as the variable E mode and Eco-gauge.

New ECOT3 Engine SAA6D114E-3

To meet EU Stage IIIA regulations whilst maintaining our industry backing fuel efficiency advantages, Komatsu introduces the all new ECOT3 engine series. Electronic control system High pression common rail fuel injection New combustion system Air-to-air cooling system

Pressurised cab

An air conditioner and air filter are fitted as standard. Together with a higher internal air pressure (60 Pa), they reduce dust entry into the cab.

Monitor function

The controller monitors engine oil level, coolant temperature, battery charge and air clogging, etc. If the controller finds any abnormality, it is displayed on the TFT.

Fingertip hydraulic pump oil flow adjustment

From the TFT monitor, you can automatically select the optimal hydraulic pump oil flow for breaking, crushing and other operations in the B and ATT modes. In addition, the flow to the attachment is automatically reduced during simultaneous operation with other working equipment. This ensures smooth motion of all working equipment. Hydraulic pump oil flow adjustment for both attachment lines is now possible.

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.

Revolving frame protection

Heavy duty side guards to protect the revolving frame from impact damage are standard. Easy removal for replacement, or for transportation when width is restricted. The bolt on side guards wrap underneath the body of the machine, to further protect vital systems. Heavy duty undercovers are also provided - protecting all of the machine systems from damage.

Undercarriage

Narrow, Long Carriage (NLC), Long Carriage (LC) or Hydraulic Wide Gauge (HWG) is available. All carriages give stable platform for work at high reach. Narrow undercarriage, with 600 mm track shoes or HWG undercarriage means machine transport width below 3,0 m (revolving frame side guards removed).

Reinforced upper structure

The upper structure of the machine is specifically designed to cope with the rigours of a demolition job site.

Tilting cab

The tilting action is fast, smooth and infinitely variable between 0 and 30 degrees, so the operator can choose the best position for maximum work visibility.

Wide, spacious cab

The newly designed, wide and spacious cab includes a heated air suspension seat with reclining backrest. The seat height and longitudinal inclination are easily adjusted using a pull-up lever. You can also set the operational posture of the armrest and the position of the console to suit your needs. Reclining the seat further enables you to place it into the fully flat state with the headrest attached.

Low vibration with cab damper mounting

A multi-layer viscous mount system incorporates a longer stroke and the addition of a spring. The new cab damper mounting combined with a high-rigidity deck reduces vibration at the operator’s seat.

Angle alarm

An equipment angle alarm is fitted, which sounds a warning buzzer in the operator cab if the equipment approaches a potentially unstable position. The device reinforces the reading of the angle indicator which is mounted on the boom, visible through the cab side window. The warning buzzer is turned off for normal excavation operations.
