Established over 40 years ago, WA Limestone is a family-owned company with quarries strategically located all over the Perth Metropolitan Area. It is known as one of the biggest suppliers of road construction materials in Western Australia. The company’s director Steven Della Bona is no stranger to the quarrying industry. He has been instrumental in Limestone’s continued growth, which now encompasses the construction of sea walls and breakwaters among various other applications within the industry. He’s also a long-standing IQA member, former chairman of the IQA’s Western Australian branch and a former national IQA director.
The excavator will be involved in the heavy lifting of 650,000 tonnes of limestone and 300,000 tonnes of granite along the breakwater.
Recently, Della Bonna’s business took on the breakwater construction on the Ocean Reef Marina, near Joondalup, about 30km north of Perth. Work is scheduled to be complete by 2022. Commissioned by the WA Government, the two breakwaters will stretch for two kilometres. Each breakwater is up to 18.5 metres high from the ocean floor and includes 650,000 tonnes of
limestone and 300,000 tonnes of granite.
The ZX690LCH-5 is WA Limestone’s first-time purchase of a Hitachi excavator
...outstanding reliability with minimal down time.
The Hitachi ZX690LCH-5 mid-sized excavator is designed for the harsh weather conditions it will encounter along the Ocean Reef coastline.
The heavy lifting of such materials has been secured with the recent purchase of a Hitachi ZX690LCH-5 mid-sized excavator. Della Bonna said Hitachi machines are “renowned for their reliability, performance and fuel economy”.
The ZX690LCH-5 features an optimised hydraulic system and engine which assures Della Bonna the machine will not only run efficiently but maintain high durability – in spite of the harsh weather conditions it will be subjected to along the coastline.
Striving to meet customer satisfaction and go the extra mile, Della Bonna remarked that “so far the machine has had outstanding reliability with minimal down time. In particular, the operator
comfort and overall machine performance is second to none. We’re also enjoying the peace of mind the ConSite Oil technology has provided, allowing us to monitor the machine’s condition and operational performance in real time.
“I’m particularly impressed with the strength of the boom arm. It seems the Hitachi excavators are equipped with more steel in this area compared to other excavators which improves the overall
lifting capacity,” he added.
This is WA Limestone’s first purchase of a Hitachi machine. Della Bonna acknowledged the support of Hitachi Construction Machinery’s major accounts manager Steve Gunn. “He made it
very easy to access the information required and provided an honest timeline on machine delivery, so I could continue to meet the demands of the Breakwater construction project.”

Meet Baxter, a fourth-year apprentice at our Adelaide branch. 👋
From working on compact excavators in the workshop to gaining hands-on experience with some of the largest Japanese made machines in the Hitachi | LANDCROS range, no two days of Baxter’s apprenticeship are quite the same.
We’re proud to support the next generation of skilled technicians with practical training, experienced mentors and opportunities to build a rewarding career in heavy machinery.
Great work, Baxter — we’re excited to see where your career takes you!
QME 2026! 🧡
Across three action-packed days in Mackay, the Hitachi | LANDCROS stand was buzzing as customers, industry partners and families got up close with our Japanese mining and construction equipment, including the mighty EX1200-7.
A huge thank you to everyone who stopped by, climbed aboard our machines and caught up with the team. It was great connecting with everyone.
See you at the next one!
A new fleet ready for the Pilbara. 💪
We’re proud to welcome KHG Contracting to Hitachi following the delivery of four new machines to support their operations in Western Australia’s Pilbara region.
The new fleet includes 2 x Hitachi ZX350LC-7G excavators, 1 x ZX890LCH-7 excavator and 1 x EX1200-7 mining excavator, bringing Hitachi | LANDCROS performance, reliability and support to the KHG team.
Pictured with the new fleet are Sait Ucal, Plant & Equipment Manager at KHG Contracting, alongside Dale, Major Accounts Manager (HCA) and Jacob, Key Account Manager Mining (HCA).
Thank you to Sait and the entire @khg_contracting team for choosing Hitachi. We look forward to supporting the machines and the team as they get to work in the Pilbara.
Built for demanding conditions. Supported where you work.
There’s only one thing better than being an operator… doing it with a view like that. 🌊
Hitachi | LANDCROS gives the precision, control and reliability RONMAC Holdings team need on this waterfront project to keep the job moving.
Proven Japanese engineering and dedicated support for a great combination of capable operators and dependable machinery.

When you`ve spent more than a decade in the industry, you know what good equipment feels like.
Working on stormwater infrastructure at Seaford Heights, Jesse from Tripodi Group puts the Hitachi 25-tonne zero swing excavator through its paces every day. From exceptional stability and impressive power to GPS integration and the added confidence of a zero-tail swing design, it`s built to perform where precision matters most.
Safer. More capable. Japanese reliability. Ready for the job.
Hear why Jesse trusts Hitachi | LANDCROS on site.
45,000 cubic metres of sand. Four basement levels. 10 machines. One serious excavation.
Faced with the challenge of removing 45,000 cubic metres of sand from a four-level basement, RONMAC brought together the right fleet for the job – including a purpose-bought long-reach attachment fitted to a 36-tonne Hitachi excavator to reach the bottom.
Working bucket-to-bucket, the team is progressively moving material from Basement 3 all the way to the surface, where it can be loaded out.
It’s a challenging job that demands the right equipment and the right support.
We’re proud to be working alongside RONMAC and even prouder to hear their team say they’re “looking forward to doing a lot more in the future” with Hitachi.
Two B45Es. One destination: getting to work. 💪
A pair of Bell B45E Articulated Dump Trucks are on the move north and ready to hit the circuit with Ezyquip Hire.
Built to tackle demanding conditions and keep productivity moving, these two are ready for what’s ahead.
A big thank you to the Ezyquip Hire team for your continued business and ongoing support.
Safe travels, B45Es!
