Graham’s Quarry and Concrete has been serving the Northern Rivers of NSW, the Gold Coast, and Brisbane since 1967. With over 80 employees and a large fleet of machines, the company is a trusted name in both quarrying and concrete supply.
Under the supervision of Site Supervisor Simon Pederson, the company operates six quarries and four concrete plants across the region. Their fleet includes 24 Komatsu machines—12 loaders and 12 excavators—all fitted with Salmon buckets. With a long-standing reputation and a strong commitment to quality, Graham’s Quarry is a key player in the industry.
In an industry where downtime and delays can mean serious losses, Graham’s Quarry faces a unique mix of challenges. Machine breakdowns, service and parts issues, and unpredictable weather—especially the heavy rains common to the Northern Rivers—are all part of daily operations.
With so many variables in play, having reliable machines and support is crucial. The harsh conditions of working with rock all day puts major stress on both machinery and attachments, making service, parts availability, and durability top priorities for Simon and his team.
To stay on top of operations, Graham’s Quarry has partnered closely with both Komatsu and SBA. Rather than relying on generic suppliers, they’ve built a strong relationship with people who understand their specific needs.
Their Komatsu fleet has proven itself time and again, supported by the quality service of Owen, their Komatsu sales representative. Meanwhile, for attachments and ongoing service, SBA has been an essential partner. Working directly with Fitzy and Mike’s aftermarket team has helped them avoid delays and keep equipment running at peak performance.
“The support we get is second to none,” says Simon. “Working in rock all day is brutal on our gear, so we need partners we can count on. Fitzy and Mike always deliver.”
Thanks to the reliability of Komatsu machines and the consistent support from SBA, Graham’s Quarry has been able to minimise downtime and keep projects on track. Their entire fleet—from 5-tonne machines to 50-tonne machines—has been well-supported with parts, upgrades, and specialised attachments to meet the exact demands of their work.
Simon puts it simply:
“With our fleet ranging from 5t to 50t, the range of Salmon and Komatsu products meets our demands. We’ve had several machines and specialty buckets—short of the odd tooth breaking, we’ve been delighted. Both Owen and Fitzy are always on the ball with solutions.”
For over five decades, Graham’s Quarry and Concrete has built its success on the foundation of solid equipment, experienced personnel, and trusted partnerships. With the durability of Komatsu machines and the tailored support from SBA’s quality attachments, the business is well-positioned to handle whatever the industry throws at it.
Simon and his team know that success in this space is about more than just machinery—it’s about having the right support behind it. And with SBA and Komatsu in their corner, they’re set for the long haul.
For a contractor like Rick Davis Contracting, juggling multiple specialised attachments can create unnecessary complexity, which is why they needed the perfect piece of equipment for their demolition needs.
Reality Escapes Landscaping has lifted output across every project since upgrading to Komatsu machines fitted with SBA attachments. The PC18 and PC35 now handle tight-access digs, backyard cuts, pool work, and detailed earthworks with speed and accuracy.
DEVCON, has been operating for over 15 years providing servicing civil construction, agriculture, and residential housing development and diverse fleet of machinery and the right attachments have been key to ensuring reliability and efficiency on every project.
