The Hänel EcoDrive lift system for
intralogistics tasks uses the compact
Mitsubishi Electric FR-A741
frequency inverter with integrated
energy recovery function. The Hänel
Lean-Lift is a fully automatic, heightoptimised
storage system.

If the FR-A741 with integrated
energy recovery function is used, it
will convert kinetic energy produced
during the downward movement of
the extractor (load-carrying device)
into electrical energy and feed it back
into the electrical supply system. It
can then be used at another location,
eg. by other Lean-Lifts within a group.

According to the travel capacity of
the lift, up to 40% of the energy
required for the downward movement
can be recovered and fed into the
power supply system. CO2 emissions
can also be reduced.
