Mining Hydraulic Hammer for 70 Ton Excavators For Sale

Moving rock in a 70-ton operation is a game of thin margins. When you are running machines like the Caterpillar 374 or the Hitachi ZX670, every hour of downtime eats your profit. You don't need marketing fluff; you need a tool that strikes hard and stays on the job.

The BLTB series hydraulic hammer for 70t excavators offers three distinct paths for heavy-duty mining. Choosing between them depends on your rock hardness and your return-line setup.

BLTB-210 Hydraulic Hammer: The Efficiency Specialist

The BLTB-210 is built for fleet managers who watch their fuel burn as closely as their production tonnages. It delivers 36,500 Joules of impact energy, providing a clean balance between high output and fuel economy.

• Best Carrier Match: Engineered for the hydraulic flow of the Caterpillar 374 and Komatsu PC700.

• System Protection: It works with your excavator’s pump rather than fighting against it, which prevents premature seal failure.

• Pro Tip: If you are working in abrasive rock, swap the chisel for a blunt tool. This ensures energy goes into the stone instead of vibrating back into your hammer housing. For more on tool selection, see our Hydraulic Breaker Working Tools - A 2025 Guide.

BLTB-215 Hydraulic Hammer: The Hard Rock Workhorse

When your site shifts into granite or basalt, tool durability becomes your biggest headache. The BLTB-215 uses a 215mm diameter tool to handle the heat and stress of hard rock quarries.

• Heavy-Duty Protection: The box housing shields the internal power cell from debris. This design lowers your maintenance costs over long, multi-shift operations.

• Carrier Versatility: This unit fits a wide range of heavy carriers, including the Volvo EC750D and SANY SY750H.

• Impact Power: At 39,500 Joules, it provides the extra force needed when a standard hammer starts to struggle. To ensure your team is prepared for this level of power, review our 5 Operating Guidelines of Excavator Hydraulic Breaker You Must Know.

BLTB-220 Hydraulic Hammer: The Impact King

Breaking the toughest ore requires mass. Weighing 9,601kg, the BLTB-220 is the heaviest option for 70 to 90-ton excavators. The weight is intentional; it provides the necessary downward pressure to stop the hammer from dancing on the surface of the rock.

• Maximum Force: Generates 41,500 Joules to shatter material that stops other hammers cold.

• Elite Pairing: Ideal for the XCMG XE800D or the Develon DX700LC.

• Critical Requirement: You must use a dedicated high-flow return line for the 390-450 L/min oil flow to prevent hydraulic overheating.
