You have just laid a pipe in a trench. Or poured a foundation. Or backfilled a utility line. Now you need to compact the soil tightly and evenly. A manual plate compactor is slow and exhausting. A large roller cannot fit into narrow trenches. What if your excavator could do the compaction itself, with a simple attachment?
That is exactly what an excavator vibrating plate compactor does. It is a heavy steel plate that vibrates at high frequency. Your excavator positions itself over the area to compact. The vibrations compress the soil, removing air voids and creating a solid, stable base. No second machine. No extra labor. Just your excavator and this attachment.
YG Machinery offers four models of excavator vibratory plate compactors: YG-32, YG-50, YG-80, and YG-107. Vibration force ranges from 40 KN to 150 KN. Excitation frequency is 2000-2200 RPM. Working pressure is 15 MPA across all models. They fit excavators from 4 tons up to 40 tons. Machine weight from 380 kg to 1050 kg.

How Does An Excavator Vibratory Plate Compactor Work?
An excavator vibrating plate compactor is a simple but effective machine.
The mechanism: Inside the compactor is a hydraulic motor connected to an eccentric weight (or weights). When hydraulic oil flows from your excavator to the motor, it spins the eccentric weight at high speed (2000+ RPM). The spinning weight creates a strong vertical vibration.
The plate: The heavy steel plate at the bottom transfers the vibration directly to the ground. The vibration shakes the soil particles, causing them to settle closer together. Air and water are expelled. The soil becomes dense and stable.
The operation: Your excavator positions the compactor over the area to be compacted. The operator lowers the plate onto the soil, activates the auxiliary circuit, and lets the compactor vibrate for a few seconds. Move to the next spot and repeat. For trenches, you can lower the plate directly into the trench and compact the backfill layer by layer.
The result: uniform, high-density soil that meets engineering specifications.
Why Choose A Hydraulic Vibratory Plate Compactor?
| Compaction Method | Problem | Excavator Compactor Solution |
| Manual plate compactor | Slow, exhausting, limited compaction depth | Excavator compactor – fast, powerful, deep compaction |
| Heavy roller | Cannot fit in narrow trenches or tight areas | Small footprint – fits in trenches, between walls |
| Boom-mounted compactor | Separate machine, expensive | Uses your excavator – no extra machine |
| Jumping jack rammer | Only for small areas, labor-intensive | Excavator compactor covers large areas quickly |
An excavator vibrating plate compactor turns your excavator into a one‑machine compaction team. No extra equipment. No extra operators.
Where Can You Use An Excavator Vibratory Plate Compactor?
- Trench compaction – Backfilling utility trenches (water, gas, electric, telecom). The compactor fits into narrow trenches where rollers cannot go.
- Foundation compaction – Compacting soil under building foundations, footings, or slabs.
- Road base compaction – Compacting gravel or crushed stone base for roads and parking lots.
- Pipeline backfill – Compacting soil around pipelines to prevent settlement.
- Retaining wall backfill – Compacting soil behind retaining walls.
- Landfill and site preparation – Compacting fill material for site grading.
- Slope and embankment compaction – Compacting soil on slopes where rollers cannot operate.
Any job that requires soil or granular material compaction – an excavator compactor can do it.
Core Advantages Of YG Excavator Compactors
- High vibration force. 40‑150 KN force – enough for most soil types, from sand and gravel to heavy clay. The YG-107 with 150 KN force can compact deep layers in a single pass.
- Wide excavator compatibility. Four models cover 4‑40 ton excavators. No matter what size machine you have, YG has a compactor to match.
- Consistent frequency. Excitation frequency of 2000‑2200 RPM ensures effective compaction. The frequency is tuned for optimal soil compaction.
- Compact design. The compactor is narrow and fits into trenches (900‑1350mm wide). You can compact backfill even in tight utility trenches.
- Easy to use. Just connect to your excavator‘s auxiliary circuit. Lower the plate. Activate. The compactor does the rest. No special training required.
- Durable construction. Built with heavy‑duty steel plates and wear‑resistant components. Designed for continuous use in demanding conditions.
- Low maintenance. No complex parts. The hydraulic motor and eccentric weights are simple and reliable. Regular greasing and inspection are all that is needed.
Why Contractors Choose YG Compactors？
Efficiency. One excavator operator can compact soil while also handling other tasks. No need for a separate compaction crew.
Quality. Consistent vibration provides uniform compaction. No soft spots. Meets engineering specifications.
Safety. No manual plate compactors – workers stay away from the vibration zone. Safer for the crew.
Versatility. Use the same compactor for trenches, foundations, road base, and site preparation. One attachment, many uses.
Cost savings. No separate compactor rental. No extra machine. Just your excavator and this attachment.
Compact Soil Faster And Better With YG
An excavator vibrating plate compactor is a simple but highly effective attachment. YG offers four models for 4‑40 ton excavators. Vibration force from 40 KN to 150 KN.

YG Machinery also offers other excavator attachments: breakers, grapples, shears, and crusher buckets. Contact YG with your excavator make, model, and typical soil type. They will recommend the right excavator vibratory plate compactor and provide a quote. Compact with confidence – choose YG.
Frequently Asked Questions
10‑18 tons. A 12‑ton excavator is perfect. A 20‑ton machine is too large – use YG-80 instead.
Yes. The excavator positions the compactor on the slope. The vibration helps settle the soil. Work from the bottom of the slope upward.
Check hydraulic hoses for leaks. Grease the pivot points. Inspect the wear plate (bottom of the compactor) for damage. Change hydraulic oil per the excavator schedule. Worn parts are replaceable.
