High Quality and Cheap Price Medium-Duty20 Ton 30 M Straight Arm Telescopic Boom Deck Crane Marine Offshore Ship Deck Cranes

Product introduction:

I. Basic Parameters

The lifting capacity of 2 tons and the maximum lifting height of 22 meters constitute the fundamental performance metrics for marine cranes, directly mirroring their load-bearing capabilities and operational reach. The lifting capacity refers to the maximum weight the crane can safely hoist, whereas the lifting height denotes the maximum vertical distance from the crane's support surface (e.g., the deck) to the center of the hook's mouth.

II. Structural Configurations

Marine cranes exhibit a wide array of structural designs, typically incorporating essential components such as booms, lifting masts (or derricks), rigging, and winches (or cargo handling machines). For a 2t22m marine crane, its structure may adopt a folding arm, telescopic arm, or straight arm configuration, tailored to meet diverse operational requirements and vessel space constraints. Each configuration boasts unique advantages; for instance, the folding arm design ensures compactness, facilitating operations in confined spaces, while the telescopic arm offers extended reach and enhanced flexibility.

III. Power Source and Control Systems

The power sources and control methods for marine cranes are similarly diverse. The power sources might encompass electric, electro-hydraulic, gasoline, or diesel engines, while control methods can range from manual operation to electric control and even more advanced automated control systems. The choice of power source and control method for a 2t22m marine crane depends on specific application scenarios, operational demands, and the vessel's electrical or hydraulic system configuration.

IV. Application Scenarios

The 2t22m marine crane finds extensive application on various types of vessels, including fishing boats, cargo ships, and engineering vessels. It is primarily utilized for tasks such as cargo loading and unloading, equipment lifting, and the deployment and retrieval of underwater operation equipment. In the demanding marine environment, marine cranes must possess exceptional stability and reliability to withstand complex and ever-changing oceanic conditions and operational challenges.
