Carrying Capacity — Comparison Evidence for Public Works

Councils & Public Works

Council and public works briefs should state the asset outcome, scope boundaries and evidence needed for acceptance. Naming a machine too early can obscure whether the work requires design, bulk excavation or surface correction.

Before moving material

Identify the asset owner, procurement brief and work-zone controls.

Receiving operation and checks

Record the verified result and any work outside the contractor's scope. Check that the completed work answers the brief rather than a machine-based promise.

No council endorsement, supplier approval or procurement status is implied.

Weight That Works

Working weight influences cutting, traction and ground loading, but weight alone does not establish grading performance. Ballast, a carried load and attachment weight also change the demands on the tractor, hitch and tyres. Consider the complete combination in both loaded and empty states.

Before moving material

Obtain the machine weights, hitch limits and tractor information.

Receiving operation and checks

Use a controlled trial to establish a workable pass depth. Observe slipping, rutting and unstable handling before chasing greater load.

More weight may damage soft ground and does not make a machine suitable for every tractor.

Capacity and Productivity Calculator

Capacity and productivity answer different questions. Nominal bowl capacity describes a planning load; production depends on load factor, cycle time, soil condition and the volume state being measured.

Before moving material

Identify capacity, realistic load factor and a complete cycle.

Receiving operation and checks

Use the estimate for planning and revise it from observations. Record whether the result is loose, bank or compacted volume.

The calculator produces an operating estimate, not a Dugong performance guarantee.

Record the job inputs

Use this checklist to turn the scenario into a specific brief. Retain the design revision and agree who accepts each completed layer.

• Existing condition, extent and the reason for intervention
• Required finished purpose, receiving operation and acceptance criteria
• Material type, layer role, source, receiving area and volume state
• Reference levels, datum, survey method and issued design revision
• Available tractor, implement configuration, travel route and turning space
• Checks before work, stopping points and evidence retained at handover

Checklist ticks apply only while this page is open. Include the completed brief in your project records.
