Common questions

Do I need a rock saw, drum cutter or breaker?

That depends on the material, required cut and working space. Send the material details, dimensions and site limits so we can assess the attachment and carrier together.

Can the setup meet our noise and vibration limits?

Share the project's limits and monitoring requirements. The method needs to be assessed for the material and surroundings; an attachment choice alone does not guarantee compliance.

Can reinforcing steel be cut by machine?

A guarded excavator and rotating shear replaced manual reo cutting on North East Link D-walls. Access, reach and guarding still need to be checked for your job.

Maintaining TBM progress with a specialist rock saw

A 25t Sumitomo rock saw with tungsten-carbide pick teeth cut cement-treated crushed rock and underlying platform material during D-wall works. The package supported cutting across six months on hire with zero breakdowns.
