Boom trucks have a lot of names — they are also called bucket trucks, cherry pickers, line trucks and aerial trucks. Regardless of the name, a boom truck is a type of utility vehicle with a telescopic or articulating arm attached to a bucket. The arm can extend (telescopic) or extend and bend (articulating), lifting a worker occupying the bucket several feet into the air for the purpose of making assessments, assembling and constructing parts, or making repairs. Boom trucks come in a variety of sizes, from small bucket trucks for light maintenance work to large bucket trucks for heavy-duty outdoor work up to 60 feet in the air.
