Komatsu Australia has released the PC1250-8 excavator/shovel, designed for applications in mining, quarrying and heavy construction.

As with other excavators in the Dash 8 line, it offers lower emissions, increased fuel efficiency and improved operator comfort and safety in a fully integrated machine/component package.
It incorporates Komatsu’s Tier 3-compliant ecot3 engine technology for significantly reduced emissions, while delivering full power and low fuel consumption.
For further fuel savings, the machine is fitted with a four-level economy mode to help the operator work in the most fuel efficient manner possible, said Kris Burford, Komatsu Australia’s National Product Manager, Mining.
With an operating weight of 107-111 tonnes in backhoe configuration options, and 111 tonnes in shovel configuration, PC1250-8 is powered by a Komatsu SAA6D170E-5 diesel rated at 502 kW.
In addition, it has an electronically controlled variable speed fan drive to reduce both fuel consumption and environmental noise. Combined with a large "hybrid fan" and low-noise muffler, the PC1250-8 conforms to the latest European noise standards.
"In addition to these environmental and fuel-saving benefits, the new PC1250-8 delivers outstanding performance," said Burford.
"It offers high drawbar pull and steering force for maximum mobility, plus digging forces of up to 48,000 kgf.
"A two-mode setting for the boom allows the operator to choose between smooth operation for moving loose material and maximum power for more effective excavating in packed material or rock," he said.
A heavy lift mode gives the operator 10% more lifting force when required.
Burford said the PC1250-8 had also been designed for maximum reliability and easy maintenance.
"It has a reversible fan to facilitate radiator cleaning combined with centralised engine checkpoints to speed up machine inspections.
"The cool-running hydraulic system is protected by the most extensive filtration system available and the interval for changing the hydraulic oil filter has been doubled to 1000 hours."
Komatsu’s Vehicle Health Monitoring System (VHMS) monitors all major components and enables remote analysis of the machine.
Burford said a large, comfortable cab features a fully reclining seat with headrest and a high-capacity air conditioner as standard, and is pressurised to prevent dust entry. An improved cab damper mounting system reduces noise at the operator’s ear to 73 dBA.
Other highlights of the new excavator include:
• Fuel consumption reduced by up to 10% compared with its Dash 7 predecessor (already recognised as one of the most fuel-efficient excavators on the market)
• A OPG-2 cab with topguard to protect the cab and operator, conforming to the latest ISO standard CHECK
• Easy-to-see large LCD colour screen offering improved visibility through use of TFT liquid crystal display, allowing on-going monitoring of all machine functions, with early warning in the event of any malfunctions, and large multi-function selection buttons for easy selection of different operating modes
• "Economy mode" to help reduce fuel consumption by providing feedback to the operator on those operations that burn more fuel – but allowing full power to be reinstated at the push of a button.
According to Burford, the new PC1250-8 delivered class-leading comfort, fuel efficiency and production to the mining, heavy construction and quarrying sectors.
"This high-production excavator/shovel is one the most modern and advanced machines on the market today, with no other equipment manufacturer able to offer Komatsu’s combination of industry-leading technology and componentry," he said.
"And because all Komatsu excavator components are designed and manufactured from the ground up to work together, we offer unmatched technology, integration and machine performance.
"The end result is an excavator that will drive down miners’, quarry operators’ and contractors’ running and operational costs.
"When you consider that our previous Dash 7 variant already had a strong reputation as being a market leader in fuel efficiency, the further savings we will be able to offer with the new Dash 8 machine are quite remarkable.
"At a time of increasing fuel prices, this is a key factor in helping keep down operating costs," said Burford.
The PC1250-8 is available in backhoe and loading shovel configurations.
