Use of a Flywheel to Reduce Power Needed to Start a Crane

It is recognised that when a tower crane is first started up it requires a ‘surge’ in electricity, and that the surge falls away once the crane is operational.

To start the tower crane on this project would require the reinforcement or upgrading of the local electricity network, and a 300kVA generator is currently being used although this is an over-provision.

The team is working with a supplier which has developed a ‘flywheel’, based on Formula 1 technology: the flywheel stores energy and results in a smaller, 100kVA generator being required.

This development is the first of its type in the country, and if successful would lead to a dramatic reduction in the amount of electricity needed to power tower cranes. It would result in significant savings in projects where numerous tower cranes are deployed.
