Claim 14:
15. A method for providing energy to energy consuming equipment, wherein use is made of the crane according to claim 1, the method comprising the steps of:
suspending the object including the energy consuming equipment from the travelling block;
connecting the input connector of the energy consuming equipment to the output connector of the rechargeable energy storage unit;
in a supply position of the travelling block, wherein the output connector of the energy charging unit is disconnected from the input connector of the rechargeable energy storage unit, operating the energy consuming equipment and/or tool on energy being supplied by the rechargeable energy storage unit and thereby discharging the rechargeable energy storage unit;
moving the travelling block to the charging position thereof by employing the hoist assembly of the crane, in which charging position the input connector of the rechargeable energy storage unit is in close proximity of the output connector of the energy charging unit assigned thereto;
in said charging position, connecting the input connector of the rechargeable energy storage unit to the output connector of the energy charging unit assigned thereto; and
charging the rechargeable energy storage unit by supplying energy from the separate energy source to the energy charging unit and via the output connector of the energy charging unit to the input connector of the rechargeable energy storage unit.
