Zusammenfassung:	A camera dolly includes an electrical system for powering a hydraulic system for raising and lowering the camera dolly arm or pedestal. The electrical system has an on-board or in-board battery, such as a lithium battery, contained within the dolly chassis. The dimensions and mechanical configuration of the dolly may optionally remain unchanged by the addition of the electrical system and lithium battery. As a result, existing camera dollies may be retrofitted with the present electrical system. The present electrical system provides a camera dolly with on-board electrical power for charging the hydraulic system. The camera dolly consequently can operate for long periods of time without access to wall current, and without using a manual pump for the hydraulic system.
