Overview

Knuckle boom cranes are articulated hydraulic cranes with folding, jointed booms that give excellent reach control in tight spaces. Their compact stowage and multi‑joint geometry make them ideal for mounting on trucks, crawlers, or fixed bases for construction, forestry, marine and material‑handling tasks where close‑in precision and flexible outreach are required. They combine high lifting power with compact transport and safe, accurate placement.

FAQ

What should I check when buying a used knuckle boom crane?

Inspect boom sections, pins, bushings and cylinder rods for wear or cracks. Check hydraulic hoses, valves and cylinders for leaks, test slewing and lifting under load, verify load charts and rated capacities, review service records, and confirm safety systems (LMI, limit switches) work.

Can a knuckle boom be mounted on a crawler carrier or loader?

Yes — many are mounted on crawlers, but confirm the carrier’s payload, stability, swing torque rating and mounting interface. You may need a manufacturer mounting kit, structural plate, additional counterweight or outriggers to meet safe operating limits.

How should I arrange shipping for a knuckle boom crane on a crawler?

Coordinate with a heavy‑haul carrier. Options include transporting assembled on a lowboy if within dimensions, or partially disassembling the boom and securing components. Plan permits for oversize/overweight loads, protect hydraulic components, and use proper blocking and tie‑downs.

What routine maintenance keeps a knuckle boom reliable?

Follow OEM intervals: change hydraulic oil and filters, grease pins and bearings, inspect and replace worn hoses, check cylinder rods and seals, torque fasteners, service the slew bearing and check safety devices. Regular load tests and non‑destructive inspections on welds/booms help prevent failure.
