Product Advantage
Lightweight Design with Exceptional Strength
Boasting a 20-ton lifting capacity, the 20 Ton Knuckle Boom Marine Crane stands out as a heavy‑duty yet compact solution in its class. It can be securely installed on various vessel decks, large workboats and offshore platforms, minimizing hull load and deck space occupation. Its optimized weight‑to‑strength ratio, combined with marine‑grade anti‑corrosion construction, achieves an ideal balance between powerful performance and long‑term durability, guaranteeing stable and reliable lifting operations in harsh saltwater, humid and wave‑impacted marine environments.
Highly Customizable for Diverse Heavy‑Duty Marine Tasks
This marine crane offers extensive customization options, including optional heavy‑duty marine winches, corrosion‑resistant hydraulic clamps, and specialized offshore attachments. Such versatility allows operators to handle large machinery, steel structures, ship supplies, containers and irregular heavy cargo with ease, tailoring the crane to the precise needs of vessel operations, offshore engineering, port logistics and large‑scale marine projects.
Precise Maneuverability with Compact Multi‑Section Boom
Constructed from marine‑grade high‑tensile steel, the compact multi‑section telescopic knuckle boom delivers exceptional outreach and strong bending resistance in limited deck spaces. It enables accurate load positioning even in narrow vessel decks, crowded offshore facilities or confined port areas, ensuring safe and efficient operation in demanding and complex marine working conditions.
Advanced Safety Features for Reliable Heavy Marine Lifts
Equipped with built‑in overload protection devices and optional torque limiters, the 20 Ton Knuckle Boom Marine Crane effectively prevents overload risks and operational accidents. Paired with stable deck support systems and a high‑performance heavy‑duty marine winch, these safety features ensure stable and secure lifting performance, even in unstable marine environments, rough sea conditions or uneven deck surfaces.
Detailed Description of Technical Parameters
Performance and Operational Specs
The 20 Ton Knuckle Boom Marine Crane is fitted with a professional marine hydraulic system featuring optimized pressure and flow settings, enabling smooth, responsive and stable control. Its slewing mechanism provides a wide rotation range, allowing full coverage of the working area without frequent vessel repositioning. The integrated heavy‑duty winch system ensures gentle and precise handling of heavy loads, making it ideal for lifting large equipment, structural components and irregular‑shaped marine cargo.
Structural and Durability Features
Crafted from high‑quality marine‑grade high‑tensile anti‑corrosion steel, the crane’s boom and frame are engineered to withstand prolonged heavy‑duty operations in harsh marine environments. It incorporates reliable friction brake and disc spring mechanisms, ensuring quiet, stable and low‑wear performance that extends the equipment’s service life under salt spray, humidity and vibration. The crane’s compact and optimized design enhances deck adaptability, supporting quick deployment on transport vessels, offshore platforms and port terminals.
