PRODUCT INTRODUCTION

The Marine Stiff Boom Crane is a robust, low-maintenance deck lifting solution featuring a high-strength steel welded box boom. It utilizes hydraulic cylinder luffing and pedestal slewing to deliver efficient, stable cargo handling. The rigid boom structure offers excellent wind and wave resistance and precise load positioning, ensuring reliable performance in complex deck environments with vessel motion and obstacles. Lifting capacities typically range from 1 to 100 tons (up to 150 tons), with a maximum working radius of up to 50 meters and 360° continuous slewing. The crane is suitable for cargo ships, engineering vessels, platform supply vessels (PSV), and offshore platforms.

FEATURES

Reliability & Low Maintenance: The fixed boom design minimizes moving parts, significantly reducing mechanical failure rates and long-term maintenance costs.

Precise Positioning: Due to the rigid boom structure, load swing is minimized during lifting, allowing for more accurate cargo placement.

Cost-Effectiveness: Compared to knuckle or telescopic cranes, stiff boom cranes offer higher value-for-money at equivalent load capacities.

Simple Operation: Features an intuitive control system that allows operators to quickly perform daily lifting and transferring tasks.
