CAT CLASS: HQ-10045

20+ in Forward Plate Compactor

The 20+ in Forward Plate Compactor class represents the widest single-direction vibratory compactors in the plate compactor family, with plate widths ranging from 550 to 1200 mm. These machines deliver compaction force from 45 to 130 kN and operating weights from 385 to 1185 kg, making them the top rung on the forward plate compactor ladder. They are purpose-built for covering large areas efficiently where reversing capability is not required—parking lot subgrade, asphalt patching over wide expanses, and other applications where maximum pass width increases productivity.

Spécifications clés

Spécification	Plage typique	Signification
Plate width	21.7–47.2 in (550–1,200 mm)	Widest coverage in the forward plate compactor category, reducing passes on large areas.
Compaction force	45–130 kN	High centrifugal force range accommodates granular base, asphalt, and mixed fill applications.
Operating weight	849–2,612 lb (385–1,185 kg)	Heavy machine mass contributes to compaction depth and static load on the material.
Engine power	6.3–24.5 hp	Higher horsepower drives larger eccentric weights and advances wide plates through dense material.

Comment choisir

The 20+ in Forward Plate Compactor is the choice when maximum single-direction coverage is the priority and the work area is large enough to justify a wide, heavy machine. It excels at parking lot subgrade preparation, large asphalt patches, and open site work where path reversals are infrequent. When the job involves tighter quarters, frequent direction changes, or the need to back out of confined spaces, the 16-20 in Forward Plate Compactor offers better maneuverability with still-generous plate widths. This top-rung class is limited to forward travel only; projects requiring reversing capability call for a reversible plate compactor instead.

Ce que cette taille peut gérer

Compacting granular subgrade for commercial parking lots and driveways
Large asphalt repair patches on roadways and lot surfaces
Base preparation for warehouse slabs and industrial pads over expansive footprints
Granular fill compaction on pipeline trenches and utility corridors
Ballast and subballast compaction along rail sidings and maintenance-of-way projects
Road shoulder repair and edge work where wide passes improve cycle time

Sécurité et opération

Operating weights exceeding 1000 kg generate substantial momentum; operators must anticipate stopping distance and avoid slopes that exceed the manufacturer's grade rating.
Wide plate widths demand clear sight lines and awareness of lateral clearances near walls, forms, and excavation edges.
High compaction forces and machine mass increase hand-arm vibration exposure; many jurisdictions require anti-vibration gloves and adherence to exposure time limits.
Engine exhaust and noise levels are elevated in higher-horsepower models; hearing protection and adequate ventilation are standard practice on enclosed or confined sites.

Transport et logistique

Machines in the 385–600 kg range typically load onto standard utility trailers; heavier units approaching 1185 kg require stouter single-axle or tandem equipment trailers with appropriate deck capacity.
Wide plates may exceed trailer width; operators often remove or rotate the base plate or use tilt-deck trailers to meet road transport limits.
Larger models in this class may require a pickup truck or light-duty tow vehicle; confirm trailer gross vehicle weight rating matches combined machine and trailer mass.

Alimentation

Gasoline or diesel engines in the 6.3–24.5 hp range; larger models favor diesel for torque and fuel economy on extended run times.
Fuel tanks sized for multi-hour operation; larger-displacement engines consume proportionally more fuel under load.
No external electrical power required; machines are self-contained with recoil or electric-start ignition.

Questions fréquentes

What distinguishes a 20+ in forward plate compactor from smaller forward models?

Plate width exceeds 550 mm, and operating weight typically surpasses 385 kg, delivering wider coverage per pass and greater compaction depth. The trade-off is reduced maneuverability and increased transport considerations compared to the 16-20 in class.

Can this size class handle asphalt compaction as well as granular base?

Yes; models in the 45–130 kN compaction-force range are suitable for both asphalt mat compaction and granular subgrade, though asphalt applications often benefit from water-spray systems to prevent mat adhesion. Operator technique and temperature management remain critical.

Why choose a forward-only compactor over a reversible model of similar plate width?

Forward plate compactors are mechanically simpler, typically lighter, and less expensive than reversible equivalents. They suit open work areas where the operator can walk continuously forward and turn the machine at the end of each pass, rather than backing up in confined trenches or against structures.
