Vertro Mechanical Poker Shafts

Frequently Asked Questions


32mm – Suitable for columns, walls, beams, and heavily reinforced concrete where space between rebars is limited.

38mm – A versatile option for general construction works, including columns, beams, and medium-sized slabs.

45mm – Recommended for slabs, footings, and larger structural elements where higher vibration output is required.

60mm – Best suited for rafts, mass concrete pours, foundations, and large infrastructure projects where faster compaction of larger concrete volumes is needed.


A Mechanical Poker Shaft is driven by an external drive unit and is commonly used with petrol or diesel drive units. The drive unit transmits rotational power through a flexible shaft to the poker head, generating vibration for concrete compaction.

An Electric Poker Shaft uses an electric drive unit connected to a flexible shaft. The vibration is produced through an eccentric mechanism, providing consistent vibration output for concrete compaction.

Mechanical Poker Shafts are typically preferred for:
  • Large construction sites
  • Remote locations without reliable electrical power
  • Continuous heavy-duty concrete pours

Electric Pokers are typically preferred for:
  • Smaller projects
  • Indoor applications
  • Sites with easy access to electrical power
  • Areas where lower noise and emissions are important

Vertro Mechanical Poker Shafts are available in lengths ranging from 6 metres to 12 metres, allowing contractors to select the most suitable configuration based on the depth and accessibility of the concrete pour.

Yes. Most Vertro Mechanical Poker Shafts can be repaired, with approximately 80% of common issues resolved through servicing or replacement of wear parts. Only shafts with major damage may require replacement.
