PC1250-11E0 Komatsu excavator specs & Dimensions (2021 - 2026)

Large drawbar pull and steering force

Because the machine has a large drawbar pull and a substantial steering force, it provides excellent mobility, even when working on an incline.

Widescreen monitor

Conveniently customisable and with a choice of 26 EU languages, the widescreen monitor with simple switches and multifunction keys gives fingertip access to a large range of functions and operating info. The KomVision images and Eco gauge are now incorporated into the default main screen.

An evolutionary interface

Helpful information is now easier than ever to find and understand with the upgraded monitor interface. An optimal main screen for the ongoing work can be selected simply by pressing the F3 key.

KomVision

With a series of high definition networked cameras fitted on the machine, KomVision provides a crystal clear, real-time bird’s eye view of the immediate surroundings on the widescreen cab monitor. The operator can quickly and easily check the machine’s vicinity prior to making any movement, and focus on the work at hand even in low light conditions.

Komatsu fuel-saving technology

Fuel consumption on the PC1250-11 is lower by up to 7%. Engine management is enhanced. The variable speed matching of the engine and hydraulic pumps guarantee efficiency and precision during single and combined movements.

Adjustable idle shutdown

The Komatsu auto idle shutdown automatically turns off the engine after it idles for a set period of time. This feature can easily be programmed from 5 to 60 minutes, to reduce unnecessary fuel consumption and exhaust emissions, and to lower operating costs. An Eco-gauge and the Eco guidance tips on the cab monitor further encourage efficient operations.

High-Pressure Common Rail (HPCR)

To achieve complete fuel burn and lower exhaust emissions, the heavy-duty High-Pressure Common Rail fuel injection system is computer controlled to deliver a precise quantity of pressurised fuel into the redesigned engine combustion chamber by multiple injections.

Variable Geometry Turbo (VGT)

The VGT provides optimal airflow to the engine combustion chamber under all speed and load conditions. Exhaust gas is cleaner, fuel economy is improved while machine power and performance are maintained.

Electronically controlled variable speed fan

The fan speed is electronically controlled according to actual operating conditions, ensuring maximum deployment of engine power to working, while minimising noise.

Information & Communication Technology

Lower operating costs Komatsu ICT contributes to the reduction of operating costs by assisting to comfortably and efficiently manage operations. It raises the level of customer satisfaction and the competitive edge of our products.

Easy cleaning of radiator

The hydraulically driven fan can reversed to facilitate cleaning of the cooling unit. In addition, this feature contributes to reducing warm-up time in low temperatures. Hinged A/C condenser and fuel cooler provide easy access to each core.

Komatsu Closed Crankcase Ventilation (KCCV)

Crankcase emissions (blow-by gas) are passed through a CCV filter. The oil mist trapped in the filter is returned back to the crankcase while the filtered gas is returned to the air intake.

Safe maintenance

Thermal guards surround high temperature areas of the engine, protected fan belt and pulleys, a pump/engine partition that prevents hydraulic oil from spraying onto the engine, a wide catwalk and exceptionally sturdy handrails: in Komatsu tradition, the highest safety level is provided for a fast and smooth maintenance.

Long-life oil filters

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

Rugged design

The undercarriage of the PC1250-11 is specifically designed to cope with the heavy forces to be found in hard quarry operations. With heavy duty double grouser track shoes and 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.

Heavy lift mode

Gives the operator 10% more lifting force on the boom when needed for handling rock or heavy lifting applications.

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 damage. The reinforced short boom and arm specification allows to increase the bucket capacity.

Shockless boom control

The PC1250-11 features a shockless valve (double-check slow return valve) that automatically reduces the amount of vibration present when operating the boom. Operator fatigue is reduced (which can improve safety and productivity), and spillage caused by vibration is prevented.

First-Class Comfort

Increased comfort In the wide Komatsu SpaceCab™, a standard air-suspended high-back seat, heated and ventilated for improved comfort and with fully adjustable armrests, is the centre of a comfortable and low-fatigue working environment. High visibility and ergonomic controls further assist to maximise the operator's productivity.

Operator Convenience

Perfect operator convenience In addition to the standard AM/FM radio, the PC1250-11 has Bluetooth and an auxiliary input for connecting external devices and playing music through the cab speakers. Two 12-volt power ports are also incorporated in the cab. Proportional controls are fitted as standard for safe and precise operation of attachments.

Komatsu SpaceCab™

The wide Komatsu SpaceCab™ with user-friendly controls provides a comfortable and safe work environment. A fully adjustable air-suspended seat dampens vibrations and reduces the fatigue of long shifts. Large front and side windows give a superior visibility and higher confidence. This increases the safety for the driver as well as other people and machines on the jobsite. A laminated one piece front glass (ECE 43R) is fitted as standard, as is the Falling Object Protective System (FOPS) with openable front sun visor. A front guard is optionally available as well.
