Telescopic Boom Cranes Explained

In the simplest of terms, a crane is a machine that is used to lift and move heavy loads, machines, materials, and goods for a variety of purposes. From construction to manufacturing to shipbuilding and material loading, cranes are used in a wide variety of settings, sectors and projects, and have revolutionised safety in the workplace.
While the world’s first cranes can be traced all the way back to ancient Mesopotamia, these days they are generally equipped with a hoist rope, wire ropes or chains, and shelves. However, many mobile and stationary cranes often feature an extendable telescopic boom - even though most people and even operators don’t understand exactly how they work, or why they make heavy lifting easier, more convenient, and ultimately safer.
How A Telescopic Boom Works In Cranes
As far as mobile cranes go, there are generally four principal types: truck mounted, rough terrain, crawler or floating. Many mobile cranes feature an extendable telescopic boom, making them an incredibly convenient option to use on worksites and other sites where space may be limited, like city areas. Though not all telescopic boom cranes are mobile cranes, many of them are truck-mounted for easy transport.
A boom is the steel arm of the crane, and is arguably the most vital component that allows the machine to hold and lift objects to a certain height. As the object is lifted, the boom extends to the desired height.
If a crane boom is telescopic, it features boom sections that extend telescopically, or having or consisting of concentric tubular sections designed to slide into one another. In turn, a crane that has a telescopic boom has greater horizontal outreach than any other type of aerial platform. Perfect for use when operators encounter different and difficult angles, telescopic boom cranes provide operators with maximum horizontal and vertical outreach.
During the boom’s extension, a hydraulic cylinder - or another mechanism if relevant - does all the hard work, making these machines so valuable on modern work sites. It enables the movement of the tubes, so the thinner ones inside get pushed outward. In turn, this makes the boom longer, and as it extends, it can reach greater heights. Unsurprisingly, it’s also this very same mechanism that enables the boom to retract. However, the major perk of a telescopic boom crane is that when it’s at its original length of only the base section, it’s easiest to manoeuvre the crane around just about any job site.
Telescopic boom lifts are also designed to boost productivity, with the ability to get into working position quickly and easily. When deployed on job sites, they’re a popular piece of machinery to use for instant scaffolding, telecommunication maintenance, external painting and decorating, arborist works, steel cladding, and much more. As a general rule, a telescopic boom crane is able to go all the way up to a maximum vertical reach of forty one metres, and a horizontal reach of twenty four metres.
Opting for mobile crane hire that features a telescopic boom is often a great way to cut down on the expenses of a construction project, and is usually the cheaper alternative when compared to the costs of buying, storing and maintaining one yourself.
However, these benefits all hinge on one simple fact - you need to avoid renting a lemon. More often than not, a less than ideal mobile crane hire company could very well cause more headaches than they do solutions, so it’s important for consumers to do their research and partner with a reputable provider - but where do you find one?
