Engineering Details
Six key engineering systems that define PF121 performance and reliability.
Nitrogen Gas Accumulator
Sealed nitrogen chamber absorbs hydraulic pressure spikes, reducing stress on the excavator hydraulic system and extending pump life by up to 30%.
Auto-Lube Greasing Port
Single-point greasing port with auto-lube compatibility. Correct lubrication interval extends chisel bush life to 800+ operating hours.
Tie-Rod Construction
High-tensile steel tie rods clamp the cylinder, front head and back head into a single rigid assembly — no welded joints in the stress path.
Wear-Resistant Front Head
Front head cast from high-chromium alloy steel, hardness HRC 52–56. Replaceable chisel bush eliminates the need to replace the entire front head.
Idle-Blow Protection
Automatic idle-blow cut-off stops the piston when the chisel loses contact with the material, preventing blank firing that damages the internal cylinder.
Dust & Water Sealing
IP67-rated dust and water seals on all hydraulic ports. Suitable for underwater operation to 10 m depth with optional deep-water seal kit.
Excavator Compatibility
Verified compatible excavator models in the 10–20 tonne class. Always confirm auxiliary flow and pressure before ordering.

Application Gallery
Six primary application sectors where the PF121 delivers proven performance.
Hard Rock Excavation
Primary breaking of granite, basalt and limestone in road construction, quarrying and foundation work.
Concrete Demolition
Reinforced concrete structures, bridge decks, retaining walls and industrial floor slabs.
Road Construction
Trench cutting through rock, pavement breaking and sub-base preparation for highway projects.
Mining & Quarrying
Secondary breaking of oversized boulders, bench preparation and ore fragmentation.
Urban Demolition
Selective demolition in confined urban sites where noise and vibration control are critical.
Underwater Breaking
Submerged rock and concrete breaking for harbour, dam and waterway infrastructure projects.
Installation Guide
Six-step commissioning procedure for the PANDA FORCE PF121.
Verify Hydraulic Compatibility
Confirm excavator auxiliary flow (80–130 L/min) and working pressure (150–180 bar). Check back pressure does not exceed 25 bar at the return port.
Mount the Bracket
Fit the correct S-type or pin-on bracket to the excavator arm. Torque all mounting pins to manufacturer specification. Fit lock pins and safety clips.
Connect Hydraulic Hoses
Connect pressure and return hoses to the breaker ports. Use the correct BSP or SAE O-ring fittings. Purge air from hoses before pressurising.
Grease the Chisel
Apply NLGI Grade 2 lithium-complex grease to the chisel shank. Initial greasing: 10 pumps. Ongoing: 2 pumps every 2 operating hours.
Set Hydraulic Flow
Set excavator auxiliary flow to 100 L/min and pressure to 160 bar for initial commissioning. Adjust within the specified range for optimal performance.
Functional Test
Test at low pressure (100 bar) for 5 minutes. Check for leaks, abnormal noise and correct impact rate. Increase to working pressure once satisfied.
Customer Case Studies
Verified field results from PF121 deployments across three continents.
