Equipment scope
Clarify whether the RFQ covers roller only, a matched tow tractor, support arrangement, monitoring and spare-parts planning.
Impact roller buyer guide
Use this guide to make the project discussion more precise.
An impact roller purchase should be evaluated as a system procurement decision. The roller, tow tractor, damping arrangement, operating space, support needs, documentation and delivery programme are interdependent.
This guide helps a procurement team request the right information from the beginning while avoiding unsupported machine-performance assumptions.

Guide contents
Questions a technical buyer should resolve before selection.
Documented parameters
Ask for source-matched model data. Current CMG published evidence supports the 32 kJ and 35 kJ pages; other model pages remain selection-led until matched data is approved.
Site compatibility
Review work area, turning space, access, gradient, material and available towing equipment.
Commercial handover
Align configuration review, documentation, delivery target and project contact route before a quotation is finalised.
Evidence boundary
A useful guide is clear about what it does not prove.
CMG uses this resource to organise a project conversation. It does not replace site investigation, geotechnical design, equipment documentation or the project acceptance specification.
- Do not accept a model-data substitution without confirming its source and model relationship.
- Do not use a product photo as evidence of the supplied scope.
- Keep project suitability and commercial scope separate from generic marketing claims.
Buyer checklist
Prepare these inputs before sending an RFQ.
- Required energy or equipment class discussion
- Material, work area and turning-space information
- Tow equipment, access and support requirements
- Requested technical documentation
- Delivery programme and project contact
Decision record
Turn the research question into a reviewable equipment brief.
Use the following record as a handover between procurement, site engineering and the equipment supplier. Empty fields are signals to investigate, not assumptions to fill with a generic machine claim.

Further questions for the project team.
Should the roller and tow tractor be specified together?
Yes. The working system should be reviewed together, including damping, access and operating requirements.
What data is currently documented on the website?
The 32 kJ and 35 kJ CMG impact roller pages contain source-matched published data.
What should drawings or project files show?
They should show relevant work area, access, turning space, interfaces and any available ground or programme information.
How does CMG prepare a quote?
CMG uses the RFQ inputs to discuss equipment family, configuration, documentation and delivery requirements.
