Hydraulic alternators are useful when electricity is needed but it is impractical or unsafe to run electrical power wires.

An example is electricity on a power line bucket truck. The operator needs electricity for communications or controls, but the bucket needs to be insulated from the truck and surrounding structures (no metal wiring).

The unit has a small hydraulic motor that spins an alternator. Typically, this is used to maintain charge on a battery in the bucket.

We have designed and delivered several varieties of this type of power generation system.
