Telescopic Knuckle Marine Crane

Telescopic Knuckle Marine Crane

--- Compact in structure, it can flexibly adjust the working radius and height.

Telescopic knuckle marine cranes are commonly employed in maritime environments such as vessels and offshore platforms for the lifting and handling of cargo or equipment.

Combining the characteristics of telescopic and knuckle booms, the crane's boom features an articulated structure comprising multiple segments connected by hinges, akin to finger joints, enabling folding motion.

Additionally, individual or multiple sections of the crane's boom can extend or retract like a telescope, allowing flexible adjustment of working radius and height. Its installation footprint occupies merely one-third that of conventional cranes.

Operating Principle:

Hydraulically driven, the telescopic knuckle marine crane employs a hydraulic system to control boom extension/retraction, folding, rotation, and hook elevation. This enables smooth and precise operation.

Application:

The telescopic knuckle marine crane is widely used on offshore supply vessels, floating production units, jack-up drilling platforms, subsea operations, and offshore wind farm support vessels. It is suitable for offshore cargo transfer, subsea equipment deployment, maintenance operations, and ship-to-ship cargo loading and unloading.

• Offshore Resupply Operations: Safe and efficient transfer of supplies between ships, and between ships and platforms.
• Port Loading and Unloading: Independently complete cargo loading and unloading without relying on dock cranes.
• Maritime Rescue Operations: Hoisting rescue equipment, small boats and conducting personnel transfer.
• Scientific Research Operations: Precisely deploy and recover scientific research instruments and sampling equipment.
