For smaller work and lighter loads, a mini crawler crane might be the right option. Of course, don't let the name fool you, these machines are still capable of lifting heavy loads, with a max lift capacity usually ranging from 1-4t. The exact capacity will depend on the make and model, but these are a great option for sites with limited access, or when you only need relatively lighter loads picked up.
That said, when most people think of crawler cranes, they picture large, mining or construction machines that can seem as big as a building. Larger crawler cranes can go all the way up to over a 600t lifting capacity. However these will generally only be found on worksites of skyscrapers or mine sites. In most cases, the 'smaller' 50t or 100t models will be enough to get the job done.
To ensure you can lift to the maximum lift capacity, most crawler cranes will come with a variety of counterweights. These usually sit on the back of the machine to balance out the weight of the load. This prevents the crane from tipping over and ensures the operator, and everyone on the job site, is safe.
Of course, the main benefit of crawler crane hire, over traditional cranes, are the tracks the crane sits on. These allow you to get a stable footing on almost any working surface. This is particularly helpful in outdoor areas, or in poor weather conditions where standard wheeled cranes wouldn't be able to maneuver.
It also allows you to transport the items you're lifting around the jobsite, as the crane is able to maintain its stability thanks to the wider grip area of the tracks. Be careful though, while you may have a max lift capacity of 50t on your hired crane, this doesn't mean it can carry that load and move around at the same time. Consult with your chosen hire company to see whether there are any limitations on lifting capacity while moving before you choose your crawler crane.
Not sure what kind of crawler crane is right for your job? Then simply talk to your local hire company. With years of experience and a range of makes and models to choose from, they can help pick the right one for your needs. Many will also offer wet and dry hire options giving you a great selection of crawler crane hire options to choose from.
