Excavator Grid Bucket: Screen and Reuse Material On Site

Sending mixed soil, stone and demolition material off site creates two bills: haulage out and replacement fill back in. The Excavator Grid Bucket screens material where it is excavated, allowing reusable fines to pass through while oversized rock, roots and debris remain in the bucket for separate handling.

Why Screen Material at the Source?

A grid bucket turns sorting from a separate processing stage into part of the excavator cycle. For contractors, the value is measured in fewer truck movements, less purchased backfill and better use of material already on the job site.

Lower disposal cost: Separate reusable soil from oversize material before it reaches the truck.

Faster handling: Load, screen and sort with one carrier instead of adding a standalone screening machine.

Cleaner output: Control the finished fraction through a grid selected for the required material size.

Select Grid Spacing by Required Output

Grid spacing is fixed during manufacturing, so it should be chosen from the required screened fraction—not from the largest opening available. A 55 × 55 mm grid is a reference configuration, not a universal answer. Tell us the input material, target output size, moisture level and hourly volume; we will match the spacing, bucket capacity and structure to the job.

Excavator Grid Bucket Technical Specifications

The 0.3–3.0 m³ capacity and 300–1000 kg weight ranges represent a product series. Final dimensions, bracket geometry and grid spacing are configured around the excavator model and application. Hydraulic control manages the screening action, while the universal mounting concept supports adaptation to major excavator brands.

Where the Grid Bucket Delivers the Best Return？

The attachment performs best where mixed material has recoverable value and transport is expensive:

Construction: Screen excavated soil for backfill, landscaping and site preparation.

Demolition: Separate fines from concrete fragments, brick and general debris.

Mining and quarrying: Grade rock and separate oversize material at the loading point.

Agriculture: Remove stones and roots during field improvement and land reclamation.

Municipal work: Process trench spoil and roadside material without a separate screening plant.
