How Auger Torque delivered ground breaking performance?

Job at Hand: Ocean Ready Mix needed conduct pre drilling for  sheet piling to loosen the ground for driving in H Beams using  a vibro-hammer. The H beams form as structural elements to reinforce the connecting horizontal wooden planks to form walls . Concrete is then poured behind the wooden walls to create retaining walls of the excavated basement level. Carrier machine used was a  Komatsu PC 400 excavator and were looking only for a compact and  modular drilling system to enable them to get close to the excavated section where the retaining wall was needed to be erected.

Challenge: (To be safe & time efficient) Our client had 300 and 350mm H beams which would require 450mm and 600mm x 4 meter deep holes to be drilled. Current system was – old chain driven system which is an offset shaft mechanism. System delivers high RPM & low torque (contrary to what was needed to drill into hard/compacted ground.)

Project  time line – 15 working days  . Total number of holes : 130 holes . Shift : 10 hours 

Existing setup  1.5 hours per hole ensuring that the set up was not feasible with the job being time sensitive. 

Solution Suggested: 

Drive Unit – 65,000 Max

Hitch Type – Single Pin Hitch

Auger Type – Hard Rock Auger with Tubular Extension

Challenge – certain parts were bespoke and needed to be fabricated /delivered within 24 hours. With support of our fabrication team – all items ordered were delivered to the customer on time. 

Result:

Client achieved the production at the rate of approximately 18 minutes per hole. Average 15 – 20 holes / day  The site was completed in 10 days instead of 15. 

Auger Torque ensured a groundbreaking solution that was efficient and safe that resulted in on time performance, higher productivity and customer satisfaction.
