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
