Step-by-Step Guide: Safely Mounting a Large Rock Breaker Attachment

Описание: Impact, harness, and rhythm three forces turning a hulking breaker into a precision tool.

This video walks through a safe, stepwise process for mounting a large hydraulic rock breaker to an excavator or carrier. Mounting a heavy attachment requires exact rigging, correct hydraulic hookups, and careful alignment so the breaker functions reliably and the carrier stays stable. The crew’s steady pace, checks, and coordinated lifts turn a risky lift into a controlled routine showing that heavy attachments become trustworthy tools only when installed with method, patience, and strict safety discipline.

The Process

1. Pre-Installation Inspection & Planning

Verify the breaker model matches the carrier’s rated carrier mass, arm reach, and hydraulic flow/pressure specifications.

Inspect the breaker for visible damage, secure tool retention pins, and check hoses and fittings for wear.

Prepare lifting gear (rated slings, shackles, and a crane or heavy lifter) and lay out the mounting pins, bushings, and spacers on a clean staging area.

Review the carrier’s hydraulic schematic and ensure required auxiliary circuits, flow controls, and relief settings are available.

2. Carrier Preparation

Park the carrier on firm, level ground and apply parking brake; lower blade or stabilizers if fitted.

Retract boom/arm to a safe mounting position per manufacturer guidance and de-pressurize hydraulic circuits.

Remove any quick coupler adapters or protective caps and clean the attachment faces and pin bores of debris and rust.

Position taglines and a spotter to control swing and keep personnel clear of pinch zones.

3. Lifting & Aligning the Breaker

Attach certified slings to designated lifting points on the breaker; use a spreader if needed to avoid twisting.

Lift slowly with the crane, keeping the breaker level and using taglines to prevent rotation.

Align the breaker so its mounting ears or bracket match the carrier’s linkage pins; approach squarely to avoid side loading.

Have ground crew verify bushing fit and that spacers line up before any pin insertion.

4. Pinning & Securing

Once aligned, insert the main mounting pins through both carrier linkage and breaker ears. Use lubrication where specified to ease insertion.

Fit retaining clips, bolts, or locking devices and torque fasteners to the manufacturer’s specified values.

Check that pivot pins rotate freely without binding and that any grease zerks are accessible for post-install lubrication.

Reinstall or connect any mechanical quick-coupler locks as required.

5. Hydraulic Hookup & Functional Check

Connect the breaker’s hydraulic hoses using correct-size fittings and torque, routing hoses to avoid kinks and pinch points.

Open the carrier’s auxiliary flow slowly, checking for leaks at fittings with hands clear of moving parts.

Set pressure relief valves and flow regulators to the breaker manufacturer’s recommended settings.

Perform a low-power functional test: cycle the breaker at low frequency to confirm actuation, observe for abnormal noises, and recheck all fittings and pin seating.

6. Final Safety & Operational Tests

With the carrier stabilized, raise the breaker slightly and perform controlled blows into a safe test block to confirm working stroke, oil temperature behavior, and carrier stability.

Re-inspect all mounting points, hose clamps, and fasteners after the initial test cycles and retorque if necessary.

Record installation details, serial numbers, and pressure settings in the equipment log for maintenance traceability.

Why This Works

✔ Matched Specs: Ensuring carrier and breaker compatibility prevents overloads and premature wear.
✔ Controlled Lifting: Proper rigging and taglines stop dangerous rotation and misalignment during heavy lifts.
✔ Correct Routing & Pressure: Proper hose routing and pressure settings protect seals, pumps, and hoses from failure.
✔ Stepwise Testing: Low-power checks catch faults early, reducing risk of catastrophic failure under load.

Key Tips

⚠ Never improvise rigging: Use rated slings and certified lifting hardware sized for the breaker’s weight.
⚠ Keep clear of pinch zones: Personnel must stand well clear while pins are inserted or the breaker is being swung into position.
⚠ Follow manufacturer torque & pressure specs: Over- or under-torqued fasteners and incorrect hydraulic pressures cause damage and safety hazards.
⚠ Bleed and filter hydraulic oil if contamination suspected: Dirt or water in the system will ruin valves and rams quickly.
⚠ Wear PPE: Hard hats, gloves, steel-toe boots, high-visibility vests, and hearing protection when testing.

Final Thought

“When heavy metal meets careful hands, a rock breaker becomes more than a tool it becomes a dependable extension of the carrier, mounted safely through planning, precision, and practiced rhythm.”
