About - The CQDF Story…

 CQ Diesel Fitting began in September 2001 when 3 mates (Andrew Shaw, Ian Corney and Jeffrey Duncan) who were Contract Diesel Fitters decided it would be beneficial to form a partnership, allowing them to have the ability to take on larger projects without affecting the breakdown service and support of their smaller customers.

 They worked out of a very small yard in Boyne Island, so small actually, that the forklift did not fit inside the shed! All major component work was carried out near the doorway so the forklift jib could reach from outside. At this point CQ Diesel Fitting slowly began to secure more customers and highly skilled staff, many of which are still with them today.

 In July 2002 CQ Diesel Fitting moved into a purpose built shed at Boys Road. The company continued to grow, assisting in projects such as:

  • The Comalco Aluminium Refinery Project with Thiess/Golding
  • Shale Oil Project and Over Burden Removal at Moura (Dawson) with Macmahon Contracting
  • Wash Plant Construction at Moura (Dawson) with Thiess/Sedgman
  • Raising the Red Mud Dam Wall with Cooks Construction.
  • Many Maintenance agreements were also formed with Orica, Downer Engineering, Walz Construction, QER, and QR National all of which remain in place today.
  • Machine and component overhauls were carried out for the Ironstone Group, Thiess, Cooks Construction, Macmahon, Downer Engineering and various other clients.

In July 2008 CQ Diesel Fitting moved into its new, modern, fully equipped workshop complex at 23 Bensted Road, Gladstone. The 10,000m2 yard was a welcome relief after almost bursting at the seams at the previous Boys Road yard.

The Company continued to grow, forming strong relationships with new clients such as Ergon Energy, Monadelphous Group, Tenkate Plant Hire, Aitken Crane Hire, Aurizon, Earth Commodities, Cement Australia and Golding Contractors.

Like most businesses, CQ Diesel Fitting has had to endure what are deemed at the company as ‘character building events’, such as the Global Financial Crisis. CQDF has faced the challenges of these difficult economic times by tackling them head on, tightening its belt and continuing to forge ahead.

More recently, CQ Diesel Fitting have been maintaining their current relationships while successfully completing additional challenges such as:

  • Providing proven skilled labour to projects for companies such as Thiess, McConnell Dowell, ABI Group, Andys Earthmovers, Egan Group, Fulton Hogan McCosker Joint Venture and Golding Contractors,
  • Completing a constant stream of 10 year Crane Inspections and Certifications on cranes for various clients including Downer Engineering and McCosker Contracting.
  • Modifying Rail Carts to a strict time frame to allow McConnell Dowell to lay the required pipeline under Gladstone Harbour.
  • Assisting Thiess Tunnelling with their machine maintenance as well as specialist repairs such as modification of their muck carts, and the provision of safety and signal solutions for their locomotives.
  • Providing a servicing solution to Wagners for their fleet of on highway trucks.
  • Providing the complete maintenance team to allow Golding Contractors to complete the RMA Upstream Embankment Construction.
  • Kobelco Service Partner Central Queensland for CA Constructions
  • Palfinger Service Partner Central Queensland for Palfinger Australia
  • CQ Diesel Fitting joined with Wabco as an ABS/EBS Service Partner.
  • In May 2013 CQ Diesel Fitting opened the Mackay Branch, Located at 112 Spiller Avenue Outer Harbour.
  • Mackay Branch offering Specialist Fuel Tanker Maintenance.
  • February 2016 CQ Diesel Fitting opened the Brisbane Branch, Located at 87 Links Avenue S Eagle Farm.
  • CQ Diesel Fitting is ready for the next stage of our journey. We aim to assist our valued customers to meet and exceed their maintenance plans and goals wherever possible in these exciting new times.
