Mass Earthworks
Crawler excavator plus dozer assist plus articulated hauler for cut-and-fill cycles measured in cubic meters per hour.
Earthworks, paving support, lifting assist, aggregate loading, piling support, drilling assist, demolition and marine bulk handling — each discipline pairs to a Tier 4 Final certified excavator or loader class with published digging depth, bucket capacity and ground pressure options.
Use the table to align ISO and EN references with VolvoBuild CE machine classes before RFQ release.
| Discipline | Key Spec | Standard | VolvoBuild CE Class |
|---|---|---|---|
| Mass Earthworks | Bucket capacity m³ & cycle time | ISO 7451 | EX-class 20–90 t |
| Paving Support | Loader bucket & travel speed | ISO 14397 | WL-class 3–8 m³ |
| Lift Assist | Capacity at radius (t @ m) | AS 2550 / ASME B30 | EX lift chart packages |
| Aggregate Loading | Throughput t/h into crusher feed | ISO 21873 | EX/AH paired fleets |
| Piling Support | Spoil rate & trench depth | EN 791 adjacent | EX mid-class + mini |
| Demolition | Reach height m & boom load | EN 13525 | HR-class 22–66 m |
Project directors often ask whether a wheeled excavator or a crawler excavator better fits a corridor that mixes soft fill with paved haul roads. Crawler machines win on ground pressure and digging depth stability; wheeled machines win when daily road travel would otherwise burn float-trailer budgets. VolvoBuild CE publishes both classes with the same hydraulic cleanliness target so fleets can mix platforms without rewriting ISO 4406 sampling SOPs.
Aggregate producers care about matching bucket capacity to jaw opening and feed size so the primary crusher never starves or overfeeds. Our application engineers size excavator buckets against crusher output capacity in tonnes per hour, then validate gradeability for the articulated haulers climbing the pit ramp. Demolition contractors receive reach-height charts and boom load envelopes before high-reach attachments leave the yard.
When marine and port packages appear in the same portfolio as quarry fleets, salt-fog maintenance intervals and stainless hydraulic fittings are specified explicitly — the discipline grid exists so those differences stay visible in the purchase order, not as afterthought change orders.
Favors broader feed-size tolerance and lower liner wear on abrasive limestone. Excavator buckets are sized so rock fragments stay inside the jaw opening without bridging — typically a more conservative bucket capacity relative to crusher output capacity (t/h).
Favors cubic product shape for asphalt aggregate specs. Face-loading excavators must keep a steadier feed rate; overfeeding raises recirculation and heat. VolvoBuild CE pairs tighter bucket-cycle coaching with the same articulated-hauler gradeability check used on jaw circuits.
