Knuckle-Boom Cranes for Sale & Rent
Knuckle-boom (articulated or loader) cranes fold at a hinged "knuckle", letting the boom bend and reach over obstacles or fold compactly for transport. They are most often mounted behind a truck cab to load and unload the vehicle itself, and are valued for precise, versatile handling in tight spaces.
They are typically rated in tonne-metres rather than a single tonnage. HIAB, Palfinger, Fassi and Effer dominate the market. Buyers look at lifting moment, number of hydraulic extensions, reach, and whether the crane has a fly-jib or winch for specialised work.

Frequently asked questions
What is a knuckle-boom crane used for?
Loading and unloading trucks, delivering building materials, and precise placement in confined spaces — construction, utilities, forestry and haulage. The folding boom reaches over and around obstacles.
Why are loader cranes rated in tonne-metres?
Because capacity depends heavily on reach: a tonne-metre figure (load × radius) captures the lifting moment. A crane lifts more close in and less at full extension.
Knuckle-boom vs telescopic (stick) loader crane?
Knuckle-booms fold compactly and reach around obstacles; telescopic booms are simpler and can be better for straightforward long-reach or overhead lifts. Many jobs favour the articulated design for flexibility.
What should I check on a used loader crane?
Hydraulic cylinders and hoses for leaks, boom and knuckle wear and play, control valves, mounting and sub-frame condition, and service history.
