Komatsu's Graders available with new features and benefits.

Graders-(1).jpgKomatsu Australia has recently begun incorporating a package of features and benefits as part of its Dash 5 "Vantage" grader offering to make it more attractive to civil contractors.

This package includes upgrading the range's standard specification to better meet the needs of contractors, and developing "plug and play" kits compatible with leading machine control system suppliers.

According to Phillip Atley, Komatsu Australia'sNational Business Manager, Government and Construction, a lot of work has gone into developing the company's Dash 5 graders for the contractor market.

"We have been partnering with Topcon distributor Position Partners and Trimble distributor Sitech to develop 2D and machine control kits that give simple 'plug and play' connectivity to our Dash 5 graders," he said.

"These kits also allow our graders to be easily upgradeable to full 3D machine control systems, giving machine owners a complete final trim and bulk grading solution."

Atley said a major factor in the appeal of Komatsu's graders and its other lines of construction equipment is the KOMTRAX remote monitoring system, which gave unmatched asset management capabilities through machine tracking and health monitoring.

"KOMTRAX constantly monitors a whole range of machine parameters including machine location, which makes it an excellent anti-theft system.

"Machine data is uploaded to Komatsu's and to our customers' machine management systems. This is proving to be a tremendous aid in preventive maintenance, as well as helping managers keep a close eye on how their equipment is being operated," said Atley.

In addition, Komatsu has upgraded its already comprehensive standard machine specification, which includes:A reversing camera and colour in-cab monitorHighly ergonomic and comfortable air seatA major improvement to air conditioning performance.

Optional equipment for Komatsu graders now includes:A "grass seed" kit to restrict grass seeds and other debris from entering the engine/cooling compartment in severe applicationsCabin pressuriser kit for mining and high-dust applicationsAuto lube system.

Komatsu's Dash 5 Vantage series of graders consists of two models, theGD555-5 and theGD655-5.

Key features include the best cab visibility of any grader on the market, increased engine power, and an upgraded version of its unique dual-mode transmission system.

Operating weight of theGD555-5 is18.1 tonnes, with variable power up to 144 kW (depending on which gear is in use), while theGD655-5 has an operating weight of18.5 tonnes, and variable power ratings of up to 163 kW.

A hexangular ROPS cab incorporates a patented front Y-shape pillar and rear side pillar to give better visibility in all grader applications.

A cast circular saddle linkage provides an unobstructed view of the blade and front tyres, while a tapered engine hood provides good visibility to the rear of the machine, particularly the rear ripper.

Both graders are powered by Komatsu's Tier 3-compliant SAA6D107E-1 the same engine which is used in a number of other Komatsu machines, including WA250PZ-6 to WA380-6 loaders, PC200-8 to PC270-8 excavators and the D51EX-21 dozer.

As with previous generations of Komatsu graders, the Dash 5 Vantage series incorporates a dual transmission system, designed to give operators the choice of direct drive (manual) transmission, as used on conventional graders, or torque converter transmission for improved control at low speeds and in final finishing.

A powershift transmission has been designed and built specifically for Komatsu graders, providing on-the-go, full power shifting as well as inching capability and automatic shifting in higher ranges.

When power for tough grading or low-speed fine control is required, the operator can select the Torque Converter auto (T/C Auto) mode for significantly more tractive effort and controland added New Feature Anti Stall Function.
