A Bucket Truck is a device that consists of a platform or bucket at the end of a hydraulic lifting system. It is often mounted on the back of a large vehicle such as a truck, or sometimes on a stand-alone trailer or self-moving platform. The bucket is designed for a person to stand in and work from. Often a duplicate set of controls that are used to manipulate the position of the bucket will be available to the person in the bucket, allowing the operator to position himself. The lifting arms of some bucket trucks are capable of telescoping to adjust the reach of the device.

Bucket Trucks were originally designed for use in orchards. It lets the picker pick fruit high in a tree with relative ease. Some fire trucks have a Bucket Truck instead of a ladder and some window cleaners may also use them. Bucket Trucks are also used in mining, construction, and sometimes by arborists to work safely in otherwise unclimbable trees.
