Grant Nykiel operates Port Vincent Landscapes, an earthmoving and excavation business located on the South Australia’s Eyre Peninsula.
“We provide services for septic, electricity and water on rural properties as well as preparation for house pads and general excavation associated with home sites“, said Grant.
“The terrain in which we operate consists of limestone rock which presents challenges when digging 400mm trenches. We had been using a rock hammer attached to our five tonne excavator, however the time needed to remove broken rock from the trenches and relocate off-site was costing us valuable time and resources.
“We found an excellent solution in the form of a G5 Rokla Rockwheel which has enabled us to undertake trenching tasks far more efficiently, with the G5 delivering around 22kW power when attached to our excavator.
“As well as significantly reducing vibration, we can now quickly grind through the limestone and in the process, create the correct grade of aggregate needed for backfill. The limestone spoil aggregate is ideal and can be compacted easily and safely for installation of plastic pipes.
“Previously, to protect plastic pipes it was necessary to extract rock fragments which had to be removed from the trench and relocated off-site; a very time consuming and costly exercise. Our first use of the G5 Rockwheel has saved us a huge amount of time and produces a good quality result.
“We did a lot of research to ensure the G5 would do the job and I’m extremely happy with the outcome. The guys from Semco gave me the information I needed so that when the G5 arrived I was able to quickly and easily attach it to the excavator and get straight to work.
“It has been a great decision; enabling me to make a big improvement in my trenching efficiency and while not in constant use, the fact that it is available when needed has more than repaid the investment”, Grant added.
Semco’s Graham Murphy said, “The Rokla twin header range provides efficient rock removal and profiling solutions that include the world’s smallest twin header rock grinder that can run on a 1.5 tonne hydraulic excavator through to the powerful G125 model (120 t Class HEX’s) with a maximum output of 440kW.
The design and power components of the low-vibration Rockwheel cutting units positioned to ensure that the tungsten carbide-tipped picks create rock chips rapidly and with reduced bounce. And the cutting heads rotate at a low speed yet with massive torque that that can handle up to 110mpa compressive strength materials and ensures a clean profile”, Graham added.
