The bucket and the excavation position define the job
Mass excavation, utility trenches, rock preparation and on-site recycling place different demands on a carrier. Write down the depth, working radius, material density and output task before comparing machines. For a truck-loading job, dumping position and bucket passes matter beside maximum digging depth.
A PC-series working-size comparison
| Model | Working weight | Engine power | Bucket range |
|---|---|---|---|
| PC130LC-11 | 12 900 - 13 200 kg | 72.5 kW @ 2 050 rpm | 0.26 - 0.60 m³ |
| PC170LC-11 | 17 600 - 19 598 kg | 90 kW @ 2 100 rpm | 0.37 - 0.95 m³ |
| PC220LC-12 | 24,200-24,800 kg | 129 @ 2,000 rpm | 0.50-1.41 m³ |
| PC240LC-11 | 25 294 - 25 574 kg | 132 kW @ 2 000 rpm | 0.58 - 1.42 m³ |
| PC360LC-11 | 35 627 - 36 535 kg | 192 kW @ 1 950 rpm | 0.68 - 1.96 m³ |
Bucket breakout force and capacity are different measures
Breakout force describes the force generated at a specified bucket geometry and test condition. Capacity describes volume. A larger bucket can carry more loose material, but it also adds bucket mass and working load; a wide edge engages more material. A rock job often changes tooth profile, penetration and wear protection as well as capacity. Compare the actual bucket and arm configuration, not volume alone.
Match a powered tool to the installed circuit
A crusher, screening bucket and rotating grapple have different flow, return and control requirements. Main-pump capacity is a machine-system figure; the tool order uses its configured auxiliary outlet. Record one-way/two-way operation, pressure, return routing, drain and rotation controls with the attachment model.
Plan the job as several useful purchase lines
| Job | Working-tool choice | Next maintenance lines |
|---|---|---|
| Demolition and recycling | Breaker plus crusher or screen | Tools, jaw plates, mesh, hoses and seals |
| Quarry and hard ground | Ripper, breaker and rock bucket | Teeth, wear plates and pin/bush sets |
| Bulk grading | Digging and grading/tilt bucket | Cutting edges, cylinders and seals |
| Logs and sorting | Fixed or rotating grapple | Rotator, pins, bearings and cylinder kits |
Give the quotation both the machine and the job
Submit the full model/arm/track configuration, attachment interface and auxiliary circuit, work material, target output and delivery point. For equipment sourcing, add new/used preference and the number of machines. For an existing carrier, attach its plate and current mount so the working-tool package includes the correct installation items.
