1. Overview

An articulated crawler crane combines the compact, flexible design of a knuckle boom crane with the stability and terrain adaptability of a tracked undercarriage. Often described as "transformers" of the lifting world, these machines offer unique capabilities that no other crane type can match .

Unlike conventional crawler cranes with lattice booms, articulated crawler cranes feature folding knuckle booms that provide exceptional reach flexibility and the ability to work around obstacles. Their modular design allows the crane body and crawler chassis to separate for transport through narrow doorways and into confined spaces .

These cranes are ideal for urban construction, industrial maintenance, indoor projects, glazing installation, and working on uneven or steep terrain where traditional cranes cannot operate.

2. Key Features

• Articulated knuckle boom – Folding arm design for maximum flexibility; can reach over obstacles and work at negative angles

• Modular construction – Crane and crawler chassis can be separated for transport through tight spaces

• Dual power (diesel/electric) – Zero-emission electric mode for indoor use; diesel power for outdoor jobsites

• Remote radio control – Operator can stand at optimal position for load visibility

• All-terrain rubber tracks – Non-marking tracks for sensitive floors; excellent traction on uneven ground

• Variable outrigger configurations – Stepless rotation (0°/45°) and telescopic extension for stability in tight spaces

• Pick-and-carry capability – Can lift and move loads within rated capacity

• Compact transport dimensions – Folds to fit through standard doorways (as narrow as 780mm)

• Advanced boom automation – P-Fold system automatically folds/unfolds the boom

• Active Oscillation Suppression (AOS) – Hydraulic system dampens boom sway for precise load placement

10.4 Pre-Purchase Inspection Checklist (Used)

• Boom: Check for cracks, corrosion, weld failures, or dents

• Hydraulic system: Inspect for leaks, hose condition, cylinder seals

• Outriggers: Verify smooth extension/retraction, cylinder condition

• Tracks: Check wear, tension, condition of rubber pads

• Engine/Power unit: Service history, operating hours, emissions compliance

• Control system: Test all functions (remote and cab if equipped)

• Safety systems: AOS, overload protection, emergency stop

• Service records: Request complete maintenance history

• Transport separation: Verify modular disconnection works properly
