Automation specialist Egemin is now offering external energy recovery for automated warehouse systems. The residual energy of stacker cranes is fed back into the mains supply and used for other processes. This means that savings in stacker crane consumption of up to 20 per cent can be achieved.
The transformer, which makes energy recovery possible, is located on the control panel of pallet cranes, miniload cranes and aisle-switching cranes. When a stacker crane brakes or lowers, the residual energy is first used to continue an internal action. When the residual energy cannot be used any more, the transformer feeds it into its own mains supply to be used for other processes.
