In modern marine transportation, fishing, port loading and unloading, offshore platforms and other fields, stiff boom cranes play a vital role. It is popular for its sturdy structure, simple operation and convenient maintenance, and is particularly suitable for scenes with limited space or harsh working environment. However, facing the dazzling array of products on the market, how to choose a truly suitable stiff boom crane? It is a question that purchasers, project managers and even equipment managers are very concerned about.

This article will systematically explain the purchase process of stiff boom cranes from multiple dimensions such as usage requirements, technical parameters, supplier selection, and after-sales service, to help you make scientific and rational decisions in the actual procurement process.

1. Clarify the usage scenarios and operation requirements

The first step in the selection is always to understand your own application scenarios and operation requirements. Stiff boom cranes are not general equipment, and there are obvious differences in the performance requirements of cranes in different usage scenarios:

1.1 Ship deck loading and unloading

The main operations are loading and unloading of cargo, catches, deck equipment, etc., which require the equipment to have high stability and corrosion resistance. It is recommended to choose a 5-15 ton stiff boom crane equipped with stainless steel or marine grade anti-corrosion coating.

1.2 Offshore platform maintenance

The operating environment is complex, with heavy loads and strong waves. It is recommended to use medium and large cranes with slewing locking function and remote control system to improve operational safety.

1.3 Port terminal auxiliary operations

For scenarios such as handling containers and material transfer, you can consider a stiff boom crane equipped with a hook or special lifting device to improve lifting efficiency.

1.4 Special application scenarios (rescue, lifeboat lifting)

This type of demand requires high response speed, and the equipment should have the characteristics of rapid deployment, compact structure and simple operation.

2. Comprehensive interpretation of key parameters

After clarifying the use requirements, the next step is the parameter selection stage. The following are several core parameters that must be focused on when purchasing stiff boom cranes:

2.1 Lifting Capacity

Refers to the maximum weight that the boom can carry within a specific working radius. It is generally measured in tons (t), such as 3t, 5t, 10t, etc. When selecting a model, ensure that its rated load is at least 20% higher than the maximum operating weight to reserve redundancy for safety.

2.2 Working Radius

The maximum extension distance of the boom determines the coverage of the operation. Different boom lengths determine whether long-distance lifting operations can be completed, generally ranging from 3m to 20m.

2.3 Slewing Angle

Common stiff boom cranes are 360-degree full slew, and some small-tonnage models are 180-degree slew. When choosing, the flexibility of the operation should be considered.

2.4 Hoisting Height

That is, the vertical distance from the lowest point to the highest point of the hook, which is especially important in tall mast ships or multi-deck platforms.

2.5 Installation method

Common ones include: base welding fixed type, flange connection type, bolt installation type, etc. The appropriate installation structure should be selected according to the hull or platform structure.

2.6 Drive type

Currently, the stiff boom cranes on the market are mainly hydraulically driven, and some small-tonnage products are electric driven. The latter has a simpler structure but limited lifting capacity.

3. Brand and Service

A high-performance stiff boom crane must not only have reliable quality, but also need high-quality service and technical support. Choosing a well-known brand or experienced manufacturer can not only ensure product quality, but also have the following advantages:

Customized service: customize arm length, lifting weight, operation method, etc. according to customer needs

Rich case experience: Stronger ability to cope with complex working conditions

Perfect after-sales guarantee: Can provide on-site commissioning, training, maintenance, and repair services

Comply with international standards: such as ABS, CCS, DNV, GL and other classification society certifications

4. Common selection misunderstandings

In the actual procurement process, many users will accidentally fall into some "selection traps", such as ignoring practicality, blindly pursuing low prices, ignoring after-sales service, etc.

The following common misunderstandings must be vigilant:

Only look at price instead of performance: low-priced products often cut corners and may have safety hazards.

Ignore arm length design: Although the lifting weight is enough, the arm length is insufficient and cannot cover the target area.

Parameter selection is too tight: The selection is too "just right" and no redundancy is reserved for emergencies such as bad weather.

Failure to consider wind load coefficient: Especially for offshore operations, wind has a huge impact on cranes, so be sure to choose models that meet wind resistance requirements.

Ignore the maintenance of later accessories: such as whether the replacement of key components such as hydraulic cylinders and swivel bearings is convenient, and whether the maintenance cycle is reasonable.

5. Additional configuration and personalized customization suggestions

On the premise of meeting the basic parameters, some additional configurations can also be considered to improve the user experience and work efficiency:

Wireless remote control system: Improve operational safety and make remote control more flexible

Explosion-proof grade design: Suitable for flammable and explosive places, such as oil and gas platforms

Stainless steel/corrosion-resistant coating: Suitable for high salt spray and highly corrosive marine environments

Hook with weighing system: Real-time monitoring of load to avoid overloading

Night lighting equipment: Ensure safe operation at night

Professional manufacturers usually support customized services, and can adjust arm length, load, color, operation mode, etc. according to customer needs.

As an efficient and stable marine lifting equipment, stiff boom cranes have shown irreplaceable advantages in many fields such as ship logistics, marine engineering, and emergency rescue. Scientific selection is not only related to the use effect of equipment, but also to operational safety and operating costs. During the purchase process, be sure to combine your own application scenarios, clarify the operation requirements, pay attention to product quality and technical services, and avoid losses caused by blind purchases.
