A boom cylinder is used to create the lift for the boom so that it extends out to lift heavy items off the ground.

A boom head is the end or head of the boom where the cable comes across. The hoist cable comes from the hoist drum up the boom and into the sheaves at the boom head and is attached to either a headache ball or a load block. In the example below a headache ball is shown.

A hook is used to move heavy or substantially large items and materials on the job site.

Outriggers are clever devices that ensure stability even on the most uneven surfaces. On a boom truck they are usually located at the base and act like a retractable arm that can be extended from the side to stabilize the vehicle and offset the load. These outriggers are “planted” so the truck cannot move while they’re in use.

A flatbed on the boom truck is typical for transporting materials to and from job sites or areas within a job site.
