The Monde excavator compaction plate is the hydraulic vibratory attachment that turns the excavator from a digging machine into a compaction machine. The operator stays in the cab and compacts soil, sand, gravel, or fill material directly after placement, without bringing a separate vibratory plate to the site.
The excavator compaction plate covers machines from 3 to 30 tonnes, with weight variants between 300 and 1,000 kg and active plate dimensions between 700×480 mm and 844×500 mm, matched to each excavator class.
The adjustable vibration frequency of the excavator compaction plate allows the compaction intensity to be adapted to the material type and the technical requirements of the project — from light compaction of the topsoil layer in landscaping work to intensive compaction of road foundations with crushed stone. The working pressure of 110–160 kgf/cm² and the flow rate of 20–80 L/min fall within the specifications of the standard auxiliary hydraulic circuits of excavators in this range. Key advantages of the Monde excavator compaction plate
• Compaction and excavation with the same machine — the excavator compaction plate eliminates the need to bring an independent vibratory plate to the site. The excavator digs, places the fill material, and compacts it in the same work cycle, without changing the machine and without additional personnel to operate separate equipment.
• Operator safely in the cab — the excavator compaction plate allows compaction to be carried out without the operator or site personnel being in the active zone. On sites with deep trenches, foundations, and areas at risk of collapse, this physical separation between the operator and the compaction zone is a critical safety requirement.
• Adjustable vibration frequency — the vibratory intensity of the excavator compaction plate is adjusted according to the material type and the required degree of compaction. Clayey soil, sand, gravel, and mixed granular materials behave differently during compaction — the adjustable frequency allows the process to be optimized for each material type individually.
• 3 plate size variants — the Monde excavator compaction plate is available in dimensions 745×450 mm, 700×480 mm, and 844×500 mm, covering the common working widths for utility trenches, building foundations, and road platforms. The plate size is selected according to the width of the area to be compacted and the tonnage class of the excavator.
• Full coverage 3–30 tonnes — the Monde excavator compaction plate range covers 3-tonne mini-excavators used in tight spaces and on sensitive surfaces, medium excavators of 10–15 tonnes for standard infrastructure work, and heavy excavators of up to 30 tonnes for high-volume earthworks.
• High-strength steel — the structure of the excavator compaction plate is fabricated from high-strength steel, sized for the cyclic loads of continuous vibration under intensive production. The active plate and the mounting frame are designed to withstand the abrasive wear specific to contact with granular materials.
• Quick mounting on the standard mount — the excavator compaction plate mounts on the excavator arm via a standard mount, compatible with the quick coupler if the excavator is equipped with one. Switching between the digging bucket and the compaction plate is done quickly on site.
• 60-month UZINEX warranty — extended coverage with spare parts in stock in Iași and national technical support with a guaranteed 24–48 hour response time.

The excavator compaction plate is the standard equipment on sites where compaction follows immediately after excavation or after placement of the fill material — the typical situation in utility work, foundations, and road infrastructure.
Compacting the backfill in trenches for pipes and cables is the most frequent application. After laying the pipe and covering it with granular material, the excavator compaction plate compacts the layer immediately, before restoring the surface. Inadequate compaction in trenches causes subsequent settlement that damages the pavement and requires costly re-intervention — the excavator compaction plate eliminates this risk through systematic layer-by-layer compaction.
Civil construction foundations require the ballast or crushed stone layer to be compacted to the degree of compaction prescribed by the designer before pouring the blinding concrete. The excavator compaction plate performs this compaction uniformly across the entire surface of the foundation, including in the zones adjacent to the formwork where an independent vibratory plate cannot reach.
Construction and rehabilitation of forestry, agricultural, and industrial roads involves repeated compaction of successive gravel layers. The excavator compaction plate mounted on the on-site excavator eliminates the need for a separate compaction roller for access roads and platforms with small and medium volumes of material.
Landscaping and professional gardening work uses the excavator compaction plate mounted on 3–5 tonne mini-excavators for compacting the sand layer beneath paving slabs, the stone beneath paths, and the fill layer beneath artificial turf — work where precise control of compaction over defined areas is essential to the final result. The excavator compaction plate versus the independent vibratory plate
The excavator compaction plate and the independent vibratory plate (self-propelled or hand-guided) are complementary equipment, not fully interchangeable — the choice depends on the type of work and the site configuration.
The excavator compaction plate is superior in deep trenches and in spaces where an independent plate cannot physically enter — trench bottoms at 2–3 metres depth, areas adjacent to foundations, embankments. Operating from the excavator cab also brings the safety advantage — personnel do not work in the active zone.
The independent vibratory plate remains more efficient on large, uniform horizontal surfaces where the maneuverability of an excavator brings no advantage over a compact self-propelled machine. On parking platforms, large-area foundation surfaces, and extensive road layers, the independent plate is more productive at similar cost.
On sites with mixed work — utility trenches and horizontal platforms in the same project — the excavator compaction plate mounted on the existing machine completely eliminates the need for a second compaction unit, reducing logistics cost and the number of machines on site. Frequently asked questions about the excavator compaction plate
What degree of compaction does the excavator compaction plate reach?
The degree of compaction achieved with the excavator compaction plate depends on the material type, the thickness of the compacted layer, the chosen vibration frequency, and the number of passes. On standard granular materials (sand, gravel 0–31mm) with a 20–30 cm layer, the Monde excavator compaction plate reaches the Proctor degrees of compaction prescribed for utility backfills and civil construction foundations. UZINEX engineers provide the technical data specific to each model at quotation. Does the excavator compaction plate also work on clayey soil?
Yes, with the note that wet compacted clay behaves differently than granular materials. The excavator compaction plate is efficient on clays at optimal compaction moisture — clay that is too dry or too wet does not respond to vibration. The adjustable vibration frequency of the Monde excavator compaction plate allows the parameters to be adjusted for cohesive soils, but the degree of compaction achieved varies more than with granular materials. Can the excavator compaction plate be mounted on the quick coupler?
Yes — the Monde excavator compaction plate is compatible with the standard mounting system, including the hydraulic quick coupler if the excavator is equipped with one. Switching between the digging bucket and the excavator compaction plate is done from the cab in less than a minute on excavators with the Monde DEHN quick coupler. Is the excavator compaction plate eligible for SEAP/SICAP public procurement?
Yes. UZINEX is a member of the Enterprise Europe Network and delivers equipment for projects with EU funds and public procurement. Complete technical documentation is provided on request. Leasing options available on the UZINEX credit and leasing page. Why UZINEX for the excavator compaction plate
