Knucklebrooms are a type of crane used to unload and move heavy equipment or cargo. It can move both vertically and horizontally. It differs from a standard or straight crane because it has two booms instead of one. A boom is a long, fixed arm that is used to move or lift cargo.
The knuckleboom is also sometimes called an articulating crane because of the way it can move. It has a main boom and an outer boom, which have a knuckle between them. This design allows the crane to be more versatile than a standard crane because it can maneuver in different ways. It’s commonly used in industries, such as forestry, construction, and mining.
One of the main advantages of a knuckleboom crane is that it can maneuver in small or tight spaces. The “knuckle” of the crane moves like a finger, which is where the name came from. Because of the shape of the crane, it can be folded into a small size. They also tend to be lighter than standard cranes, which makes them easy to transport.
A knuckleboom crane first became popular in Europe. The knuckleboom was used because the roads are narrower than in the United States and there are more restrictions on truck size. Those two factors meant certain industries needed a crane that could fit into smaller spaces. The knuckleboom then started to become increasingly popular in other parts of the world including North America because of how well they work in tight spaces.
Although they work well in narrow spaces, they still have the power of a straight crane and can lift cargo in excess of 60 tons. Knuckleboom cranes can be mounted onto trailers, tractors, and trucks. The cranes have varied control systems including ground control and radio remote control.
