IN SEARCH OF THE PERFECT SURFACE

Specialist New Zealand earth moving contractor Tony Wilson is a man in constant search of the perfect surface.

His relentless obsession with providing his clients with a completely perfect - which in most cases means level - base on which to build has led him to even invent his own soil and earth compactor.

According to Tony his new machine, developed entirely in New Zealand, has far less drag substantially reducing the tearing of the fill, with a fuel saving of up to 50 percent, and less environmental impact compared to commercially available compactors.

Field trials have been so successful that he intends taking the machine to market by the end of 2021.

It's a big step up for the CEO of family-owned Cameron Civil, a 44-machine strong company which Tony started with his wife Lynley, in 2002.

Tony and Lynley bought the business from long-time Auckland contractor Allan Cameron, who remains a mentor and supplier of machinery to the company.

Their daughter Katie made news in Auckland two years ago when she bought her own Komatsu D65 bulldozer and became, at 19, one of the first female earth moving contractors in New Zealand.

Tony almost simultaneously bought a Komatsu D61PXi-23 dozer fitted with a fully factory integrated intelligent machine control [iMC] system to use initially, on a major project for the RNZAF's Whenuapi airbase, in West Auckland.

According to Tony, the OEM iMC system enabled the bulldozer to achieve grader-quality trimming tolerances of 25mm, better than half that of aftermarket GPS solutions he had been using.

The iMC system incorporates stroke sensing hydraulic cylinders with load sensing hydraulics which automatically adjust to enable transition from rough dozing to high-precision finish grading.

"In many cases, we've been able to eliminate the grader phase of a final finish operation because the D61 has delivered the required quality," he said.

As part of his pursuit of the perfect surface, Tony had been an early adopter of aftermarket trimming systems, achieving between 50 and 70mm tolerance, enough to enable a grader's final finishing pass to be relatively simple.

On each job, he established a flat Plane surface- on which the cutting and trimming coordinates of his machines were checked daily to ensure they were optimised.

It is a technique similar to setting-up successful racing cars to ensure all corners of the vehicle are evenly balanced.

"With the D61, we have a Komatsu technician come on-site to fine-tune the electronics specifically to requirements of the job, to ensure its providing the maximum result," he said.

The Whenuapi airbase required ground preparation to a depth of 1.1 metres to construct 15,000 square metres of hard stand and taxiways. Cameron Civil achieved the complex task first time, and ahead of schedule.

Cameron Civil is now trialing Komatsu's PC210LCi-10 excavator with Intelligent Machine Control, with the view to expanding its range of OEM-fitted precision aids.

"The iMC system on both the Komatsu dozer and excavator are semi-autonomous and don't require special operator skills to run it," Tony said.

"We employ skilled operators for their general proficiency because our jobs will always benefit from having people with years of experience who know best how to employ the tools we use."

Tony makes a point of spending time on his machines himself.

"It's important to know what we're doing and hands on experience brings with it, a respect from the operators that you wouldn't otherwise necessarily get," he said.
