The knuckle boom crane, also referred to as a loader or an articulating crane, is a hydraulically-powered articulated arm fitted to a trailer or truck (thus becoming a knuckle boom truck). The crane, when attached to the truck is used for for loading/unloading the vehicle. Once the cranes job is completed, it can be folded and stored neatly and conveniently due to its numerous jointed sections (one or more of which may be telescopic) on the back of the knuckle boom truck.

The knuckle boom crane folds down to a compact size, but also extends a long way, giving it many advantages over a stiff-boom or telescopic crane, such as increased payload, a lower profile, long reaches that compete with telescopic cranes, increased control and versatility.


Unlike most cranes, the operator must move around the vehicle to be able to view his load; hence modern cranes may be fitted with a portable cabled or radio-linked control system to supplement the crane-mounted hydraulic control levers.Often the crane will have a degree of automation and be able to unload or stow itself without an operator's instruction. The versatility of the crane can be seen in the fact that it can function like a regular straight boom, after which it can fold up as per specific requirements.

Ideal for Moving or Floating Job Sites

Use of a knuckle boom crane has been seen in a variety of cases like in maintenance of an atrium and launching a life boat. A knuckle boom crane can also be mounted on a barge and used to transport goods. It is, however, an efficient and versatile piece of equipment that, with the correct attachment can be used for everything from road construction through to lifting, carrying and moving jobs. The knuckle boom crane, which is capable and often does perform the role of the drywall boom crane, has the following operation choices: stand up control, ground control, top-seat control, or wireless radio remote.


As the name suggests, a knuckle boom crane, is a crane with a knuckle in its boom. The knuckle boom is comprised of a crane that basically looks like a finger, with the articulation being the knuckle


Boom Truckrs or Boom Cranes


Knuckleboom Trucks - A newer version of the crane family, knuckleboom trucks improve upon the idea of telescoping booms with a folding arm known as a knuckle or articulating boom to improve portability. The lifting arm folds down for more compact storage, unfolds for use, and includes an end section that either extends or telescopes to reach desired heights. It can swivel and is generally much more flexible at working in and around job site obstacles as well as in smaller working areas. Limited by vehicle base size, smaller knuckleboom trucks are often found in light industrial applications, while heavy-duty versions are found working as unloaders and material lifts at construction sites, warehouses, piers and more.
