1. An energy supply system for a tool attachable to a hoist, the energy supply system comprising:
a line storage for winding and unwinding an energy line around a winding center of the line storage device;
a carrier configured to carry the energy line, the line storage having an opening for intake and removal of the carrier and the energy line; and
guides configured to guide the carrier through the opening so as to guide the carrier and the energy line in sections in the line storage to the winding center of the line storage via;
a first guide section through a first guide arch, and
a second guide section adjoining the first guide arch and through a second guide arch, and
a third guide section adjoining the second guide arch and lying further inwards than the first guide section relative to the winding center,
wherein the carrier has an outer, first end and an inner, second end, and
wherein the carrier has a first section with guides and a second section without guides, the second section without guides extending from the second end to the first section with guides,
wherein the carrier is connected to the winding center at the second end of the carrier, and the second section without guides is unguided in the line storage, and
wherein the unguided section of the carrier is windable spirally around the winding center, and a winding radius of the unguided section of the carrier increases or decreases as the guided part of the section of the carrier is wound or unwound.
