You already own an excavator. It sits on your job site, ready to work. Yet when it comes time to compact backfilled trenches or prepare subgrade, you bring in a separate compaction machine. Another piece of equipment. Another operator. And another cost. What if your excavator could handle compaction too?
That is exactly what an excavator vibrating plate delivers. This attachment mounts to your excavator arm in place of the bucket. Hydraulic power drives a vibrating plate that compacts soil, granular materials, and asphalt with the same machine you already use for digging. The YG series excavator vibrating plate comes in multiple models, with four popular configurations covering excavators from 4 to 40 tons. While we manufacture a full range, these four represent the models most contractors choose for their daily work.

Advantages of the Excavator Vibrating Plate
Every excavator vibrating plate adopts an optimized hydraulic vibration structure with tiered performance specifications from 40KN to 150KN vibration force to match diverse construction depth standards.
1. Graded Vibration Force Matching Different Construction Demands
Our model lineup covers vibration force from 40KN up to 150KN. Low-force 40KN and 65KN units suit shallow landscaping and light residential compaction work, while 110KN and 150KN heavy-duty variants handle deep trench backfill and heavy aggregate compaction for municipal infrastructure projects. All excavator vibrating plate models hold a stable excitation frequency above 2000 RPM; large-size units boost frequency to 2200 RPM for faster material settlement.
2. Stable Hydraulic Operating System
All attachments run under a fixed 15MPA standard working pressure to maintain steady vibration output. The maximum hydraulic flow requirement ranges from 60L/min for small models to 160L/min for heavy units, matching the standard hydraulic output of mainstream excavator brands. The internal hydraulic oil circuit uses wear-resistant sealing parts to stop oil leakage during continuous operation.
3. Wear-Resistant Hitting Surface & Balanced Frame Structure
The rectangular hitting area ranges from 900×550mm to 1350×1050mm across all models, offering large single-pass compaction coverage to reduce repeated rolling cycles. The thickened hitting plate resists abrasion from sharp gravel and crushed stone, extending the service cycle of core working components. The balanced body weight (380KG to 1050KG) avoids excessive load on the excavator stick and arm joints, preventing premature wear of the digger hydraulic and connecting parts.
4. Full Compatibility & Fast Installation Design
Standard connecting brackets fit most mainstream excavator brands without customized transformation. Operators can swap this vibrating plate for excavator with buckets, breakers and other attachments within minutes using standard quick couplers. Complete taillight, mechanical and hand brake matching structures support safe road towing when moving the excavator between job sites.
Complete Model Selection Guide
Picking a suitable mini excavator compactor attachment requires four core reference indicators, and we break down each selection standard to help buyers avoid mismatched equipment.
Step 1: Confirm Your Excavator Operating Tonnage
Each model corresponds to a clear excavator weight bracket: YG-32 for 4–9T micro and small diggers, YG-50 for 10–18T medium excavators, YG-80 for 20–27T mid-heavy machines, YG-107 for 30–40T heavy-duty excavators. Mismatched tonnage leads to insufficient compaction power or excessive arm load damage.
Step 2: Check Excavator Hydraulic Maximum Flow Rate
The excavator plate compactor relies fully on the digger hydraulic supply. Small models need at least 60L/min flow, while large heavy units require 160L/min stable output. If your excavator’s auxiliary hydraulic flow fails to meet the parameter standard, the attachment cannot reach full vibration force output.
Step 3: Define Target Compaction Depth & Material Type
Shallow compaction within 30cm of soft soil only needs low-vibration-force models. Deep trench backfill over 50cm, or hard mixed gravel aggregate, requires high 110–150KN vibration force variants to hit qualified compaction density in fewer passes.
Step 4: Measure Regular Working Space Dimensions
For urban narrow trenches and indoor renovation foundation work, choose compact frames and small-sized models. Wide open highway and quarry construction sites can select large hitting area units to raise daily construction throughput.
Long-Term Service Life Maintenance Standard
Correct daily and periodic maintenance directly extends the service life of hydraulic compactor attachments, cutting unplanned downtime on construction sites. Most site operators ignore standardized maintenance steps, leading to premature vibration motor failure and plate abrasion.
Post-Shift Daily Cleaning Work: After every full work shift, wash gravel, mud and crushed stone residue off the hitting surface and hydraulic connector joints. Residual sharp aggregate scratches, sealing rings and corroded metal frame surfaces during storage. Dry all hydraulic joints completely before placing the attachment into storage.
Scheduled Vibration Motor Lubrication: Add dedicated high-temperature grease to the vibration motor bearing every 50 continuous working hours. Low lubrication levels create metal friction inside the motor, reducing excitation frequency and weakening compaction force over time.
Weekly Hydraulic Circuit Inspection: Check all oil pipes, sealing rings and valve joints for oil leakage once per week of use. Minor leaks waste hydraulic power and pollute construction materials; replace aging sealing parts immediately upon discovery.
Off-Season Storage Protection Rules: When the attachment sits unused for more than two weeks, coat the hitting plate and exposed metal brackets with anti-rust oil, and store the whole unit under a waterproof covering in dry, ventilated areas. Never leave the vibrating plate for excavator exposed to long-term rain or snow erosion outdoors.
