Abstract
A vehicle for carrying a camera crane has wheels or treads on a chassis. A battery pack assembly on the chassis, includes an AC to DC converter and plurality of batteries wired to a battery charger within a housing. The batteries collectively may have an output voltage of 30 to 36 VDC when fully charged. At least one input connector on the housing is wired to the AC to DC converter for charging the batteries. The battery pack assembly replaces and is used instead of a camera-equipment-generator.
Claims11
A vehicle for carrying a camera crane, comprising:
- a chassis;
- a plurality of wheels rotatably attached to the chassis;
- a surface on the chassis for supporting a camera crane;
- and
- a battery pack assembly on the chassis, including an AC to DC converter and a plurality of batteries wired to a battery charger within a housing, the batteries wired to one or more output connectors and collectively having an output voltage of 30 to 36 VDC when fully charged, and at least one input connector on the housing wired to the AC to DC converter for charging the batteries, the battery pack wired so that wall current provided to the at least one input connector is converted to 30 to 36 VDC and is provided to the output connectors for powering camera equipment, and the batteries automatically disconnected from the output connectors via one or more relays when wall current is provided to the at least one input connector;
- and
- the vehicle having no camera-equipment-generator.
4 more elements
A camera crane, comprising:
- a chassis;
- a plurality of wheels rotatably attached to the chassis;
- a column pivotally supported on the chassis;
- a crane arm pivotally supported on the column;
- a battery pack assembly on the chassis, the battery pack including an AC to DC converter and plurality of batteries wired to a battery charger within a housing, the batteries wired to one or more output connectors and collectively having an output voltage of 30 to 36 VDC when fully charged, and at least one an input connector on the housing wired to the AC to DC converter for charging the batteries, the battery pack wired so that wall current provided to the at least one input connector is converted to 30 to 36 VDC and is provided to the output connectors for powering camera equipment, and the batteries automatically disconnected from the output connectors via one or more relays when wall current is provided to the at least one input connector;
