Marine Crane Introduction

A marine crane is a type of crane that is used in marine and offshore environments, such as on ships, oil platforms, and other offshore structures. Marine cranes are used for a variety of tasks, including loading and unloading cargo, transferring materials and equipment, and performing maintenance and repair tasks. According to the structure, the marine crane can be divided into the fixed boom, knuckle boom, telescopic boom and telescopic knuckle boom.

Marine cranes can be powered by a variety of sources, including electric, hydraulic, and diesel engines. They are typically designed to be compact and durable, with features that make them suitable for use in harsh marine environments, such as corrosion-resistant materials and special coatings to protect against saltwater damage.Marine cranes can vary in size and capacity, from small cranes used on fishing boats to large cranes used on offshore drilling platforms. They may also have special features such as telescoping booms, multiple hoisting lines, and automated controls to improve efficiency and safety.

From the design, stage to dispatch, our internal quality assurance systems fully comply with the marine class standards. In addition, third-party surveyors will check the process of design and fabrication to ensure the marine crane complies with all relevant specifications.
