low noise ex­ca­va­tions

Rokla model D10 Rock­wheel sig­nif­i­cantly re­duces noise when ex­ca­vat­ing rock on jobs where it’s not de­sir­able or prac­ti­cal to use a rock ham­mer

Many home­own­ers are look­ing to ex­pand their liv­ing space by fo­cus­ing un­der­neath their homes to add a base­ment level as well as, or some­times in­stead of, adding lev­els above.

In re­sponse, a num­ber of spe­cial­ist con­trac­tors have emerged who have geared up to meet the chal­lenges pre­sented by sub-floor ex­ca­va­tion. As well hav­ing to get equip­ment to the site, spoil also needs to be re­moved that may com­prise con­crete or hard rock. One of these con­trac­tors is Mel­bourne’s SLE Ex­ca­va­tions.

“There are times when it’s not de­sir­able or prac­ti­cal to use a rock ham­mer for the re­moval of hard ma­te­rial,” SLE Ex­ca­va­tion’s Shane Lind­say ex­plains. “Apart from ex­ces­sive noise, trans­mit­ted vi­bra­tion can be an is­sue for ad­join­ing res­i­dents and in meet­ing noise and vi­bra­tion lim­its im­posed by lo­cal coun­cils.

“These is­sues were solved when we pur­chased a Rokla model D10 Rock­wheel. We have found this ex­tremely pow­er­ful cut­ting unit to be ro­bust, re­li­able and ver­sa­tile.”

The Rock­wheel en­ables them to sig­nif­i­cantly re­duce noise when ex­ca­vat­ing rock in sen­si­tive ur­ban ar­eas where even the op­er­a­tional hours of noise sup­pressed ham­mers may be re­stricted.

“The D10 Rock­wheel is lighter in weight than most other twin-head­ers on the mar­ket. We find it can de­liver pow­er­ful per­for­mance, even when at­tached to a smaller ex­ca­va­tors. We have no­ticed it has a high-torque hy­draulic en­gine and picks are mounted on the drums at an an­gle that gives max­i­mum power to pen­e­trate tough ma­te­rial.

“We have also found the de­sign en­ables picks to grip strongly and hardly ever bounce, en­abling the cut­ting heads to ro­tate at a speed that achieves out­stand­ing ex­ca­va­tion that en­sures a clean pro­file.”

Rokla at­tach­ments are avail­able from Semco’s sales and ser­vice cen­tres in Sydney, Mel­bourne, Newcastle and Quean­beyan, as well as via Semco’s na­tional dealer net­work.
