PC700LC-8 Komatsu excavator specs & Dimensions (2012 - 2014)

Low noise design

Komatsu Dash 8 crawler excavators feature the lowest in-class external noise levels and are especially well-suited for work in confined spaces or urban areas. Reduced fan speed, a large capacity radiator, and the optimal usage of sound insulation and of sound absorbing materials help to make noise levels inside Dash 8 excavators comparable to those inside an executive car.

Excellent visibility

The PC700-8’s large capacity cab and increased glass area provide superb front visibility. Large mirrors on both sides ensure that machine visibility meets the latest ISO standards. Additional work lamps and a rotating beacon are fitted as standard, further enhancing safety.

Laminated front screen

The front screen of the PC700-8 is made of laminated glass, for enhanced protection against chips produced by rock breaking work. The single-piece design offers an uninterrupted view of the working area.

Low consumption ecot3 engine

Designed and manufactured by Komatsu, the SAA6D140E-5 engine provides high torque, a better performance at low speed, and low fuel consumption. With direct fuel injection, turbocharger, common rail air-to-air aftercooler and cooled EGR system, productivity and fuel efficiency are maximized. The Komatsu SAA6D140E-5 engine is certified for EU Stage IIIA and EPA Tier III emission regulations.

Hydraulic drive radiator cooling fan

The engine cooling fan rotation speed is electronically controlled and depends on the engine coolant and the hydraulic oil temperatures: the higher the temperature, the faster the fan will turn. This system increases fuel efficiency, reduces the operating noise levels and requires less horsepower than belt driven fans.

Less ambient noise

The PC700-8 is an exceptionally powerful machine that maintains low operating noise levels. In addition to the electronically-controlled variable-speed fan drive, external noise levels are further reduced to meet EU Stage 2 noise regulations by a low-noise glass wool furnished muffler with cover, a hybrid fan, and low-noise components.

Eco-gauge and idle caution

The unique ECO-gauge helps the operator reduce emissions and fuel consumption for environmentally friendly and energy saving operations. To further avoid wasting fuel when the machine is not actually working, a standard-fit idle caution is displayed if the engine idles for 5 minutes or more.

Selectable working modes

The selectable “Power” or “Economy” modes are designed to match the engine speed, pump speed and system pressure to the current application. They give the operator the flexibility to match the equipment performance to the job at hand. The Economy mode has 4 stages, for an optimum combination of economy and production, while Power Modes can be switched to reduce fuel consumption where maximum breakout force is not needed.

Safe and easy maintenance

Thermal guards are placed around high temperature parts of the engine. The fan belt and pulleys are well protected and in case of damage, fire risk is reduced by a pump/engine partition that prevents hydraulic oil from spraying onto the engine.

Steps connected to the machine cab

For easy engine and maintenance, steps allow access from the left hand catwalk to the top of the machine.

High pressure in-line filtration

The PC700-8 has the most extensive filtration system available, providing in-line filters as standard equipment. An in-line filter in the outlet port of each main hydraulic pump reduces failure caused by contamination.

Long-life oil filters

The hydraulic oil filter uses high performance filtering material for long element replacement intervals, which significantly reduces maintenance costs.

Cab damper mounting

The built-in stability of the Komatsu PC700-8, combined with a highly rigid deck and a sprung multi-layer viscous mount system, drastically reduces vibration levels for the operator.

Safe SpaceCab™

Specifically designed for Komatsu excavators, the Dash 8 cab has a tubular steel frame. It provides very high shock absorbency, impact resistance and durability. The seat belt is designed to keep the operator in the safety zone of the cab in the event of a roll-over. At your request, the Komatsu PC700-8 can also be fitted with an ISO 10262 Level 2 Falling Object Protective System (FOPS).

Safe access

A wide catwalk and large handrails give safe and easy access to the cab and to maintenance check points. Very durable anti-slip plates – with additional high friction covering – maintain long term traction performance.

Rugged design

The undercarriage of the PC700-8 is specifically designed to cope with the heavy forces to be found in hard quarry operations. With a wide range of heavy duty double grouser track shoes and a number of different roller guard options, the moving parts of the undercarriage are strongly shielded against damage from rocks, while traction force and ground pressure may be optimized for your particular site.

Swing priority mode

A twin swing motor system provides excellent swing performance, with high speed and strong braking power. The swing priority setting allows using the same smooth motion for either 180° or 90° loading operations. By altering the oil flow, the operator selects either boom or swing as the priority for increased production.

Lifting mode

For fine control work or for heavy lifting applications, the operator can select the lifting mode to gain 17% more lifting force on the boom.

High strength boom and arm

Thanks to the large cross-sectional structure made with high tensile strength steel and a thick plate and partition wall, the boom and arm provide excellent durability and are highly resistant to bending and twisting. Highly durable rubbing strips on the underside of the arm protect the structure from any material that might fall from the bucket. The reinforced short boom and arm specification allows to increase the bucket capacity.

Wide spacious cab

The wide and spacious cab includes a newly designed heated air suspension seat with a high backrest. The seat height and longitudinal inclination are easily adjusted with a pull-up lever. You can also set the operational posture of the armrest and the position of the console or recline the seat all the way and place it into a fully flat state with the headrest attached.

Pressurised cab

An automatic air conditioner, an air filter and a positive internal air pressure (60 Pa) combine to prevent external dust from entering the cab.
