Product Overview
The TGEC excavator compaction wheel is a purely mechanical attachment built specifically for compacting soil in tight utility trenches, pipeline ditches, and other confined excavation sites where standard compaction gear simply won't fit. Its padfoot drums work a kneading action that densifies cohesive and mixed soils layer by layer, using the excavator's own boom and curl functions. This makes it a natural fit for utility contractors, civil crews, and pipeline installers who regularly work in restricted-access conditions.
We offer five wheel models that span excavators from 1 all the way up to 39 tons, with wheel widths from 450 mm to 650 mm and working diameters reaching 1090 mm. Every model is sized to match the lift capacity and linkage geometry of its target machine class. Within the TGEC excavator compaction attachments family, this wheel pairs with the hydraulic plate compactor—which is better suited for broad, open-area surface work.

How It Works
This wheel runs entirely off the excavator's mechanical linkage—no auxiliary hydraulics, no extra plumbing. The operator drops the padfoot drum onto the soil using the boom, then uses the curl function to roll the drum forward and backward across the compaction zone. As the drum turns, the padfeet penetrate and knead the soil, pushing out air voids and building density pass after pass. The combination of the excavator's downforce and the wheel's own weight delivers the compaction energy, while the narrow drum profile lets you work in trenches only slightly wider than the wheel itself.
Application Scenarios
Pipeline trench backfill: Compact soil layers around water, sewer, gas and telecommunications lines in narrow utility trenches.
Foundation excavation backfill: Densify soil in building foundation pits and around basement walls where access is restricted.
Roadside ditch and culvert work: Compact backfill around drainage structures, culverts and roadside ditches.
Confined-area compaction: Work in narrow trenches, between structures and in areas where ride-on rollers cannot maneuver.
Cohesive soil stabilization: Knead and densify clay and silt soils that respond better to sheepsfoot-style compaction.
Utility and municipal projects: Compact backfill on street repairs, water main replacements and underground utility installations.
Embankment and slope compaction: Compact soil layers on embankments, slopes and retaining wall backfill.
Installation & Mounting
Mounting the compaction wheel is straightforward—it pins onto your excavator's bucket linkage using the existing bucket pins, with no hydraulic hoses to mess with. Before you start, confirm your machine's pin-to-pin spacing, pin diameter, and coupler type (direct pin-on or quick coupler), since those determine the right bracket. Also double-check that the attachment weight is within your excavator's lift capacity at working reach. TGEC supplies brackets customized to each excavator model, and the whole swap usually takes less than an hour with basic shop tools.
Wear Parts & Service
The main things to watch are the padfoot tips, the drum surface, and the mounting pins and bushings. Check the padfoot tips regularly for wear or breakage—once the protrusion height drops below the effective compaction range, it's time to ｒｅｐｌａｃｅ them. Keep an eye on the drum surface for cracks or distortion, especially after working in rocky or abrasive ground. And stay on top of greasing the pins and bushings to avoid premature wear and keep the drum rotating smoothly. We stock genuine replacement padfoot sets, pins, and bushings for every TGEC compaction wheel model.
Dealer & Bulk Orders
TGEC supplies compaction wheels to equipment dealers, civil contractors, and pipeline installation firms around the world. We offer bulk pricing and OEM private-label programs based on product selection, order quantity, and your target market.

Request a Quote — Excavator Compaction Wheel
Since this is a mechanical attachment, you don't need an auxiliary hydraulic circuit. To get a quote, just send us your excavator make and model, operating weight, pin-to-pin spacing, pin diameter, coupler type, and which model you're looking at (TG-CW100 through TG-CW400). We'll confirm the right wheel size and bracket for your machine. We can also supply custom pad configurations for specific soil conditions.
