Motion roof support rebuilds: integrated project lessons for mine engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
A longwall mine roof support system requiring a complete overhaul was rebuilt by Motion using its integrated national network to deliver a fully compliant, site-ready package. The project involved complete strip-down, inspection and refurbishment of hydraulic legs, canopies and base units, with all critical components reconditioned or replaced to OEM specifications and certified to relevant Australian Standards. Centralised project management and in-house machining, hydraulics and testing shortened turnaround and reduced interface risk compared with multi-vendor rebuilds, offering a template for future large-scale support refurbishments.
Technical Brief
- Motion coordinated strip-out, rebuild and reinstallation through a single project team to maintain traceable accountability.
- All hydraulic legs were dismantled to component level, enabling detailed inspection of bores, rods and seals.
- In-house machining of worn pins, bushes and clevises reduced reliance on third-party workshops and transport interfaces.
- Pressure testing of hydraulic circuits was conducted under controlled workshop conditions before dispatch to the mine.
- Canopy and base structures underwent non-destructive testing to identify fatigue cracking prior to any weld repairs.
- Replacement parts were sourced through Motion’s national inventory system, limiting substitution risk and ensuring material traceability.
- Centralised documentation captured inspection records, test certificates and conformance reports into a single safety file for site acceptance.
- Single-vendor rebuilds like this reduce coordination gaps that often lead to incompatible settings or undocumented safety-critical changes.
Our Take
Motion’s repeated appearance in recent Australian Mining pieces – from upgraded workshops in Mackay, Rutherford and Perth (22 Feb 2026) to consolidated WA fluid power services (13 Jan 2026) – signals a deliberate push to be a full-service maintenance partner for Australian underground and surface operations, rather than just a components supplier.
The focus on hydraulic and mechanical reliability in the Exitflex hose and Fenner coupling articles linked to Motion suggests that any roof support rebuild programme in Australia can likely be integrated with broader drivetrain and fluid power upgrades, reducing unplanned downtime across multiple systems rather than treating roof supports as a standalone asset class.
Within our Mining category coverage, Motion is one of the more frequently recurring service brands in safety- and product-tagged pieces, indicating that Australian operators are increasingly leaning on third-party specialists for critical support equipment overhauls instead of relying solely on in-house workshops.
