What is a Boom Truck?
Everybody's seen them; the phone and cable company vans scurrying about with the long arm folded back over the roofs. In most cases, a bucket-like apparatus sits at the extension of the extendable arms. These vans exemplify a type of utility vehicle known as a boom truck.
A bucket boom truck, sometimes called a cherry picker, is a vehicle with an extendable boom mounted to the bed or roof. A bucket boom may be used to lift workers to the top of a phone or electrical pole, or to a high roofline. Also known as an aerial boom truck, these trucks are a fairly common sight around town. Bucket boom vehicles typically have a lifting capacity of some 350 pounds (158.76 kg) to 1500 pounds (680.39 kg), and may extend the bucket up to 34 feet (10.36 m) in the air.
Larger vehicles, construction boom trucks, or heavy equipment boom trucks, may have a crane at the rear of the truck that’s used to lift heavy items onto the truck bed. These cranes may be short and compact, called a knuckle boom, or the boom crane may extend the length of the truck bed, which is a trolley boom. Crane boom trucks have a lifting capacity of 10 tons (9.07 metric tons), to approximately 50 tons (45.36 metric tons) for some of the larger vehicles.
There are also concrete boom trucks. The booms on these types of vehicles contain a pipe with a nozzle at the far end, and are used to pump concrete and other materials into specified areas. These areas are, in most cases, inaccessible to the vehicle, or are at a considerable height. The boom on a larger concrete boom truck may be extended some 230 feet (71 m). Material is then pumped from the vehicle through the extended boom and directly into the space where it is needed.
Many fire departments are equipped with a fairly lengthy bucket boom to raise firefighters to the upper levels of a building. From there, they may direct water onto the flames, or they may be used to rescue trapped victims. Boom trucks are often a replacement for, or an adjunct to, many of the older hook-and-ladder trucks.
There is, as well, a small self-propelled boom truck, similar to a forklift that is available for large warehouses or manufacturing facilities. These mini boom trucks can lift workers to the ceiling of the building or to upper storage areas. They are far safer and more convenient than using an extension ladder for the same purpose.
I've always heard of this kind of truck being called a cherry picker, since that was one of the most common things it was used for, but I guess "boom truck" makes sense as well. They would call it that because of the arm.
There's a few things that are also called "boom" like the boom mic that they often use on movie sets in order to capture sound without putting the mic in the picture. They also have a long, extendable arm.
And I know that the spar at the bottom of a sail is also called a boom.
@Bgirl - I think it depends on which country you're in but usually, yes, you'll need a special license in order to drive a boom truck crane. They usually fall under the same kind as an ordinary crane, I believe and you might be able to get one that covers both.
Generally, they'll offer a course through the local authority. Make sure you do your research so that you are taking a proper, registered course or you might not learn what you need to learn in order to get the license.
You might also want to make sure it's not worth your while to take a slightly larger course that will get you a couple of different licences as sometimes it's cheaper to do a whole bunch of them with one payment and those licences definitely come in handy.
Do you have to have a special kind of license to drive a boom truck?
