The main advantage of a DC powered crane over a hydraulic crane on a boom truck is ease of installation. For example, since BIGMAX electric cranes come with their own battery operated power pack, the crane can be mounted on any vehicle including trucks, trailers, and boats which has an adequate battery and sufficient stability. No separate, often costly hydraulic system is required as on a hydraulic crane.
The main disadvantage of DC powered cranes on boom trucks is that, because it is battery operated, the crane has a limited duty cycle. While ideal for more occasional use, a battery powered crane can usually run for 5 minutes every 20 minutes or so, depending on the battery strength and whether the battery is being constantly charged.
