PC130-8 hydraulic excavator

The Super Long Front is not an arm bolted onto a catalog machine: it is a Komatsu factory arrangement, built from the frame up. It carries additional factory counterweight, frame reinforcement and optimized hydraulics to hold that reach without compromising the machine's balance. It goes on the PC210LC-10, PC240LC-10, PC290LC-10, PC360LC-10, PC390LC-10 and PC490LC-10, with fronts from 15.2 to 19.8 metres. The arm tucks under the boom so the machine transports without dismantling the front.

• Rehabilitation of waste and settling ponds in plants
• River and creek bank maintenance and stabilisation
• Dredging of waterways and bridge foundations
• Irrigation and drainage ditch maintenance
• Highway sloping and landscaping
• Cofferdam and slurry-wall construction in light soils

A long front trades breakout force for reach: the front is sized against the project's actual depth and material, not the other way round. The ranges below are factory catalog figures — the reach that applies to your site comes out of the technical visit.

A pontoon undercarriage that spreads the machine's weight over a far larger footprint: the excavator floats and moves across mud, mangrove and saturated ground where a conventional track sinks on day one. It combines with a long front when the work is also far from the bank, and with an amphibious carrier when the spoil has to leave the working face.

• Shrimp ponds: building, cleaning and maintaining pond walls
• Wetlands, mangroves and estuaries
• Irrigation and drainage canals on saturated ground
• Work on flooded areas and river margins

The configuration depends on the site's soil type and water depth: it is defined in a technical visit before quoting.
