What is a full knuckled boom crane?
A full knuckled boom crane is a lifting equipment with multiple foldable boom sections connected by joints. It can flexibly bend and extend to perform complex lifting and handling operations. Featuring a compact multi-joint boom design, it achieves the maximum working range within limited deck space and can complete lifting tasks at complex angles without the need for additional support structures.
The crane primarily consists of a vertical support column (including its base and tower sections), multiple articulated arms, a hoisting mechanism, a slewing mechanism, and a luffing mechanism. The boom sections are connected by joints, enabling bending at various angles and enhancing operational flexibility.
Working Principle
A hydraulic system powers the full knuckled boom crane.
The telescoping of hydraulic cylinders is controlled to realize the bending and extension of boom sections, thereby achieving the lifting, lowering, and movement of goods.
The crane's tower body can generally rotate 0 ° to 360 °, and when coordinated with the movement of the boom sections, it enables precise positioning and handling of goods within a wide working range.
Core Advantages of full knuckled boom crane
Precise Controllability : The multi-joint design enables flexible operation around obstacles, achieving intelligent lifting that bypasses rather than crosses barriers.
Intuitive Human-Machine Interface: A control system that complies with maritime operational habits reduces training time and operational errors.
All-Weather Operation Capability: The sealed electro-hydraulic system and anti-corrosion coating ensure stable operation in harsh environments with salt spray and high humidity.
Safety-Priority Design: Multiple overload protection and emergency stop systems ensure the safety of personnel and cargo.
Space Optimization: The folded footprint is reduced by more than 40%, maximizing available deck space.
Simplified Maintenance: The modular design enables quick on-site replacement of key components, minimizing vessel downtime.
Durable Structure: Marine-grade steel and special anti-corrosion treatment are employed to withstand long-term offshore service conditions.
Configuration Flexibility: Multiple load configurations, ranging from 0.5 to 50 tons, are available, adapting to various types of vessels and operational requirements.
Classification Society Certifications: CCS, DNV-GL, ABS, RS, RINA, NK, KR, BV, etc.
