This fixed boom deck crane adopts an electro-hydraulic drive mode with a rated lifting capacity of 30 tons. Its jib is designed with a box-type structure, featuring a stable and strong load-bearing capacity. It also offers advantages such as high stability, easy operation, and convenient maintenance, making it suitable for various operating scenarios, including ships of different types and port terminals.
The design and manufacturing of this deck crane comply with the norms and standards of the Registro Italiano Navale (RINA).
YFM can provide pre-sales consultation as well as after-sales installation and commissioning services, offering an efficient and reliable solution for the loading and unloading of heavy cargo.
Composition and components
The construction of the 30 Ton fixed boom deck crane
Straight arm: Made of high-strength alloy steel, it serves as the main load-bearing structure. It is usually welded either as a single piece or in sections, featuring high strength and rigidity, and is capable of withstanding large lifting weights.
Lifting mechanism: Composed of a motor, brake, reducer, drum, wire rope, etc. The motor supplies power, which drives the drum to rotate through the reducer and controls the retraction and release of the wire rope, enabling the lifting and lowering of goods. The brake is utilized for emergency braking when needed to ensure safety.
Slewing mechanism: Includes a slewing ring and a slewing drive. The slewing ring connects the superstructure and the base of the crane and can bear large axial force, radial force, and overturning moment. The slewing drive device enables the crane to rotate horizontally, allowing the straight arm to rotate within a certain angular range so as to lift goods to different positions.
Base: Usually a steel structural frame, it is fixed to the offshore platform or ship deck by means of bolts or welding, etc., providing a stable supporting foundation for the crane. Various mechanisms and equipment are installed on it.
Electrical control system: It is composed of an operation console, a frequency converter, a PLC controller, sensors, etc. The operator issues commands through the console, and the PLC controller precisely controls the speed and direction of the motor based on the commands and the information fed back by the sensors, thus realizing the precise control of actions such as the crane's lifting and rotation.

Product advantage
advantages
The fixed boom deck crane also has significant advantages compared to other cranes.
Simple structure:
The structure of the fixed straight arm is relatively simple. Lacking a complex folding or telescopic mechanism, it has fewer parts, which results in high reliability and reduces the probability of failure. Moreover, it is convenient for maintenance.
01
Good stability
The fixed-structure design of the straight arm enables the crane to have better stability during the lifting process. It can effectively reduce the cargo swing caused by the shaking or deformation of the boom. Thus, it is especially suitable for operations with high requirements for lifting accuracy.
02
Large lifting capacity
Since the straight-arm structure can better withstand bending moments and torques, and the fixed-connection method can provide more stable support, the fixed straight-arm offshore crane usually has a large lifting capacity. It meets the lifting needs of large equipment and heavy objects in offshore engineering.
03
Strong corrosion resistance
Corrosion-resistant materials and special anti-corrosion coatings are usually used for protection. They can effectively resist the erosion of salt spray and seawater in the marine environment, prolong the service life of the crane, and reduce maintenance costs.

Shipping
Regarding the Transportation Methods of our fixed boom deck cranes:
Full-unit Transportation
Depending on the crane specifications, we will arrange container or flat rack transportation accordingly. For extra-large cranes, bulk carrier transportation will be adopted.
Knock-down Transportation
Our cranes are designed with a modular structure, which can generally be disassembled into multiple units for transportation based on container dimensions. Among these units, oversized components will be directly secured inside containers by lashing, while electrical parts and accessories will be transported in plywood cases.
