Komatsu has released a new grader, the GD655-7, incorporating a number of technology innovations compared with its predecessors as well as other graders on the market – aimed at making it easier to use and more productive. The equipment will be exhibited at the IPWEA International Public Works Conference from 25 to 29 August in Hobart.
The GD655-7 is powered by a Komatsu SAA6D107E-3 Tier 4 Final-compliant variable horsepower engine, rated at 134-165 kW (depending on gear and operating mode) and with an operating weight of 19.3 tonnes with rear ripper.
Technology innovations include updates to the transmission and control improvements that make it easier to operate, for reduced operator fatigue and increased safety, as well as being factory-fitted to take any of the many 3D machine control system options available from leading third-party suppliers.
According to Phil Atley, Komatsu’s National Business Manager, Government & Construction Graders, the GD655-7 grader represents a significant technology step forward in grader design and ease of operation.
“We’re highlighting these enhanced grader control systems as putting the future at your fingertips,” he said.
These technology innovations include an all-new operator station, with features such as EPC (electronic proportional controls) for blade and ripper functions, and the option of dual-function palm-controlled steering or a conventional steering wheel.
“Our EPC palm control systems greatly cut down operator effort, reducing hand/wrist movements by 95%, and resulting in far lower operator fatigue and improved jobsite safety,” said Atley.
“In addition, this new grader retains our unique dual-mode direct drive and torque converter transmission system, upgraded with a new range change and forward/reverse controls for reduced driveline shock – and again contributing to reduced operator fatigue and very long service life of transmission drive line components.
“The Tier 4 Final Komatsu engine, which has been matched to the Komatsu-designed and built transmission, driveline and hydraulics, results in fuel consumption reductions of five to 15 per cent compared with our previous models,” he said.
Standard on the GD655-7 are factory-fitted cabling, controls and bracketing for multiple makes of 3D machine control systems, allowing customers to simply install a ‘plug and play’ kit to use with their own or a rented 3D machine control system, with no additional cabling or brackets.
“With this ‘plug and play’ installed, customers can go straight to work with an 3D GPS system from Trimble, Topcon or other leading suppliers, without having to spend money and time on preparing the machine,” said Atley.
“We believe these technology advances, including improved ease of use, increased safety and true machine ‘plug and play’ gives our new grader strong appeal to Australian owners and users.”
Brief specs of the GD655-7 are: Operating weight, with ripper, 19.3 tonnes; engine Komatsu SAA6D107E-3 Tier 4 Final-compliant variable horsepower engine, rated at 134-165 kW (depending on gear and operating mode); blade length, 4.27m; transmission, full powershift with lockup torque converter with anti-stall function ; speeds, 8F/4R, maximum speed, 44.3km/h; overall length, 10.875m; industry leading minimum turn radius, 7.4m.
