CAT CLASS: HQ-10043

Up to 16 in Forward Plate Compactor

Up to 16 in forward plate compactors are the smallest self-propelled vibratory compactors in the forward-travel category, with plate widths from 320 to 400 mm (approximately 12.6 to 15.7 inches). This size class excels in confined work where maneuverability outweighs production speed—fitting between form boards, along building perimeters, and in narrow trenches where larger machines cannot operate. Operating weights range from 54 to 135 kg, keeping them light enough for frequent repositioning while delivering compaction forces between 10.5 and 25 kN.

Spécifications clés

Spécification	Plage typique	Signification
Plate width	320–400 mm (12.6–15.7 in)	Determines access into tight spaces and between obstacles
Compaction force	10.5–25 kN	Effective for granular soils and thin lifts in shallow applications
Operating weight	54–135 kg (119–298 lb)	Light enough for one operator to maneuver and load without mechanical assistance
Engine power	1.8–3.6 hp	Gasoline engines sized for the modest vibration and travel demands of compact plates
Vibration frequency	85–100 Hz	High-frequency vibration suited to thin lifts and granular base materials

Comment choisir

This size class is appropriate when workspace constraints—formwork edges, building walls, utility lines, or trench widths below 18 inches—prevent access by wider equipment. The narrow footprint and low weight make it the default choice for residential backfill, sidewalk subgrade, and small patch repairs. When compacting open areas larger than a few square meters, or when lift thickness exceeds 4 inches, the 16-20 in Forward Plate Compactor delivers faster coverage and deeper energy transfer without sacrificing meaningful access. No smaller forward-travel plate exists; projects requiring even tighter access typically shift to hand-held rammers or trench rollers.

Ce que cette taille peut gérer

Backfilling narrow utility trenches 12–18 inches wide
Compacting sand or gravel base inside concrete form boards
Patch work on driveways, sidewalks, and residential paving
Perimeter compaction along foundation walls and retaining structures
Preparing subgrade for interlocking pavers in tight courtyards
Backfill compaction around manholes, valve boxes, and small structures

Sécurité et opération

High-frequency vibration transmitted through handles; anti-vibration gloves reduce operator fatigue
Low center of gravity and modest weight limit tip-over risk on slopes, but operation on grades above 15° is not recommended
Exhaust positioning and ventilation matter in confined trenches or against building walls
Operators should maintain stable footing; loose soil and narrow trenches increase slip hazards

Transport et logistique

Light enough for one operator to lift into a pickup bed or small utility trailer
Typical 54–135 kg weight requires no specialized loading equipment or ramps
Compact footprint allows stacking with other hand-guided tools in enclosed trailers

Alimentation

Gasoline-powered engines in the 1.8–3.6 hp range, typically Honda or equivalent
Integral fuel tanks hold enough for several hours of intermittent operation
No external power or hydraulic hookup required; self-contained operation

Questions fréquentes

What is the maximum lift thickness this size can compact effectively?

Compaction forces of 10.5–25 kN and operating weights under 135 kg typically limit effective compaction to lifts of 3–4 inches in granular materials. Cohesive soils or deeper lifts require multiple passes or a heavier machine.

How does plate width relate to trench or form clearance?

Plates in this class measure 320–400 mm wide; operators typically need an additional 2–3 inches of clearance on each side for safe hand positioning and vibration clearance, making 18-inch trenches the practical minimum for comfortable operation.

When does it make sense to use a rammer instead of this forward plate?

Rammers deliver higher impact energy per square inch and work better in cohesive soils or very narrow spaces under 12 inches. Forward plates in this size class offer faster travel speed and smoother operation on granular base and sand, where cohesion is not the limiting factor.
