Conveyor chutes and transfer stations often operate within some of the most congested areas of a mining or bulk-materials-handling facility.
Existing conveyor structures, head pulleys, discharge points, walkways, pipework, guarding, electrical services and structural steel can all affect the design and installation of a replacement chute or transfer-station component.
Where drawings are incomplete, outdated or unavailable, relying only on manual measurements can increase the risk of fabrication and installation problems.
Hamilton By Design provides engineer-led 3D laser scanning, mechanical engineering and CAD modelling services for chute, conveyor and mining fabrication projects throughout Newcastle and the Hunter Valley.
Capturing Existing Chutes and Transfer Stations
Terrestrial 3D laser scanning can capture the visible geometry surrounding an existing chute or conveyor transfer point.
Depending on site access and line of sight, the captured point cloud may include:
Conveyor head and tail pulley locations
Belt centreline and discharge geometry
Existing chute walls and transition sections
Supporting beams and columns
Flange and bolted connection points
Skirt plates and sealing arrangements
Wear-liner interfaces
Maintenance platforms and walkways
Guards, handrails and access stairs
Pipework, cable trays and nearby services
Available lifting and installation clearances
The registered point cloud provides a coordinated three-dimensional reference that can be used during design, modelling and fabrication detailing.
Supporting Replacement Chute Fabrication
Replacement chute projects may appear straightforward until the existing chute is removed and previously hidden interfaces are exposed.
Problems can arise when:
Existing steelwork differs from historical drawings
Conveyor structures have been modified
Connection holes do not match the available documentation
Pulley or belt positions differ from the nominal design
Nearby services restrict installation access
Replacement sections cannot be transported through the available route
Lifting points or crane access have not been considered
New wear liners interfere with adjoining components
Scanning the installation before fabrication begins can help identify these issues while modifications can still be made within the CAD model.
This approach can support the fabrication of:
Transfer chutes
Rock boxes
Diverter chutes
Feed chutes
Discharge chutes
Bifurcated chutes
Hopper transitions
Skirt systems
Wear-liner assemblies
Dust-enclosure components
Conveyor guards
Maintenance platforms
Replacement support steelwork
From Point Cloud to Fabrication Model
After the site has been scanned, the individual scan positions are registered into a coordinated point-cloud dataset.
The point cloud can then be used as a reference for developing the required engineering and fabrication information.
Depending on the agreed scope, deliverables may include:
Existing-condition point-cloud data
3D CAD interface models
Chute and transfer-station models
General arrangement drawings
Sections and elevations
Fabrication drawings
Replacement structural-steel models
Installation and assembly drawings
Clash-review models
STEP, SAT or Parasolid files
SolidWorks parts and assemblies
AutoCAD DWG or DXF files
Autodesk ReCap RCP or RCS files
E57 or LAS point-cloud files
The proposed chute or replacement assembly can be positioned within the point cloud to check its relationship with the existing conveyor, structure and surrounding services.
Chute Geometry and Material Flow
A point cloud records the existing physical installation, but it does not replace the engineering assessment of material flow.
Chute design may also require consideration of:
Material type and bulk density
Lump size and particle distribution
Moisture content
Belt speed and capacity
Material trajectory
Impact angle
Wear zones
Material degradation
Dust generation
Blockage and hang-up risk
Required liner materials
Inspection and clean-out access
Where appropriate, the existing site geometry captured by laser scanning can be combined with mechanical design, CAD modelling and material-flow assessment.
This allows the proposed chute geometry to be developed around both the material-handling duty and the physical restrictions of the existing transfer station.
Brownfield Mining and CHPP Projects
Brownfield mining projects regularly involve fitting new equipment into plant that has been modified over many years.
Original drawings may not include:
Previous conveyor modifications
Temporary structures that became permanent
Added pipework and cable trays
Replacement guarding
Modified access platforms
Changes to pulley or drive arrangements
Corrosion repairs
Locally fabricated brackets and supports
Capturing the current installation helps project teams work from the plant as it exists today rather than relying only on historical documentation.
This can be particularly useful for:
CHPP chute replacements
Conveyor upgrades
Crusher and screen modifications
Transfer-station refurbishments
Wear-liner replacement projects
Dust-control improvements
Conveyor guarding upgrades
Shutdown preparation
Structural-steel replacement
Maintenance-access improvements
Planning Chute Work Before a Shutdown
Shutdown time is limited, and unexpected fit-up problems can affect multiple trades and work fronts.
Scanning can be completed before the shutdown to support the development of replacement components while the plant remains substantially assembled.
The available data can help the project team review:
Existing connection points
Proposed removal sequence
Replacement section sizes
Transport and access routes
Crane and lifting clearances
Site welding requirements
Bolted assembly options
Temporary support requirements
Maintenance access
Potential clashes with other work
This does not remove the need for appropriate engineering verification, site safety planning or critical manual measurements. However, it provides a more complete spatial record for planning the fabrication and installation work.

Engineer-Led Scanning for Practical Fabrication Outcomes
The purpose of scanning is not simply to collect the largest possible point cloud.
The scanning plan should be developed around the engineering and fabrication problem.
Before attending the site, consideration should be given to:
Critical fabrication interfaces
Required dimensional accuracy
Hidden or restricted areas
Scanner line of sight
Proposed installation sequence
Modelling requirements
Required drawing outputs
File formats required by the fabricator
Critical dimensions requiring manual confirmation
Planning the scan around the intended outcome helps ensure that the captured data is useful to the designers, fabricators and installation team.
Planning a Chute or Transfer-Station Project?
Hamilton By Design supports mining companies, CHPP operators, engineering contractors, maintenance teams and fabrication workshops across Newcastle and the Hunter Valley.
To discuss a project, provide any available:
Site photographs
Existing drawings
Chute or conveyor sketches
Equipment information
Material-handling requirements
Proposed shutdown dates
Required CAD formats
Fabrication deliverables
Installation timeframes
Hamilton By Design can then review the project and recommend an appropriate scope for site scanning, point-cloud processing, engineering, 3D modelling and fabrication drawing support.
