A knuckleboom loader is a specialized crane which has three hinges on its boom. Its name reflects the similarity to the joints on a human finger.
The three hinges on the boom allow for more flexibility and control when loading and unloading cargo. It can be self-standing or mounted onto the bed of a truck. The crane is lighter than a traditional boom crane, eliminating the need for special certification by the operator. The crane is often remotely controlled, increasing safety and ease of operation. Mounted onto the bed of the truck, the boom allows for better operation in small places.
Knuckleboom loaders are utilized in many industries, including marine, construction and forestry. Logging operators use the loader in conjunction with a delimber to begin processing the felled trees on site.
