Energy recovery thanks to frequency converter with integrated feedback unit on the Hänel Lean-Lift®
The Hänel EcoDrive®, which was first unveiled at CeMAT 2008, is an integral part of the Hänel EcoConcept. Since its launch, this system has been continuously developed and improved. The Hänel EcoDrive® helps to save energy and consequently to reduce costs. The frequency converter uses the energy of the descending extractor and converts it back into electrical energy.
This is then fed back into the supply system and can be used elsewhere, for example on other Lean-Lifts® in a network. Depending on the rate of travel, up to 40% of the energy fed in previously for the upward run can be recovered in this way.
