Taming the Basalt — HB20G’s Performance in the Saudi Desert
The Challenge: Rocks as Hard as Iron
In the Tabuk region of Saudi Arabia, a major highway expansion project faced a grueling obstacle. The terrain was dominated by volcanic basalt—a rock so dense and abrasive that standard hydraulic breakers struggled to penetrate it. With temperatures soaring above 45°C (113°F), the project manager, Mr. Ahmed, was facing a crisis: his existing equipment was overheating, and the pistons were losing impact power, threatening to delay the entire project timeline.
The Solution: The HWX HB20G “Quarry Master”
After researching high-durability attachments, Mr. Ahmed’s firm imported our HB20G Hydraulic Breaker. Specifically designed for 20-ton class excavators (in this case, paired with a CAT 320D), the HB20G was selected for its superior heat dissipation and its high-strength 135mm alloy steel chisel.
“We needed a hammer that could strike fast and hard without giving up in the desert heat,” Ahmed noted. Our technical team verified the “Golden Three Parameters” of his CAT 320D to ensure a 100% seamless fit before shipping.
The Result: Precision and Power Under Pressure
From the first strike, the difference was undeniable. The HB20G delivered a consistent 400-800 bpm impact rate, shattering the basalt blocks into manageable pieces with surgical precision.
Zero Overheating: The advanced hydraulic circuit design allowed the breaker to run for 10-hour shifts without the hydraulic oil reaching critical temperatures.
25% Efficiency Boost: The project moved forward faster than expected, reducing fuel consumption per ton of rock broken.
Durability: After three months of continuous “quarry-style” demolition, the main cylinder and through-bolts showed minimal wear, proving the quality of HWX’s heat-treatment process.
Client Feedback
“In the Middle East, heat and rock are our greatest enemies. The HWX HB20G turned those enemies into manageable tasks. It’s not just a tool; it’s the heartbeat of our excavation site,” said Mr. Ahmed.
