In the field of modern industry and shipbuilding, cranes are one of the important heavy machinery and equipment and are widely used in various lifting and handling tasks. As one of the important types, stiff boom cranes have become common equipment in offshore platforms, ports, ships and other fields with their simple structure, stable operation and strong load capacity. This article will analyze the structure and working principle of stiff boom cranes in detail, and deeply explore its applicable scenarios and advantages to help users fully understand the functions and application value of this equipment.

1. Basic structure of stiff boom crane

stiff boom crane, as the name suggests, is a lifting equipment designed with rigid boom. Unlike telescopic boom cranes and rotating boom cranes, the boom part of stiff boom cranes is usually made of steel or alloy steel, with a fixed shape and cannot be extended or bent, so its structure is relatively simple and more stable. The overall structure usually includes the following core parts:

Boom

The boom is the most critical part of the stiff boom crane and bears most of the weight. The boom is usually made of steel or alloy steel, and adopts a high-strength, wear-resistant design to ensure that it can work stably for a long time under high load. The length of the boom is fixed, and its angle can be adjusted to meet different operating requirements.

Boom support system

The boom of a stiff boom crane is usually firmly supported by a set of support systems. These support systems include pillars, brackets, steel cables and tie rods, etc., which are designed to maintain the stability of the boom and avoid structural deformation caused by excessive load or external forces.

Crane base (carriage)

The base of a stiff boom crane is the supporting foundation of the entire equipment and carries the center of gravity of the crane. The base is usually equipped with crawler, wheeled or ship-borne support systems to ensure stable operation of the equipment in various environments. For stiff boom cranes used on ships or offshore platforms, the base also needs to have a corrosion-resistant and high-temperature resistant design to ensure that the equipment can adapt to harsh marine environments.

Hoisting system (crane winch)

The hoisting system is responsible for hoisting, lifting and placing loads. It usually consists of an electric or hydraulically driven winch, which lifts or lowers the cargo through a wire rope or chain. The selection and design of the lifting system determines the lifting capacity, speed and accuracy of the stiff boom crane.

Control system

The control system consists of two parts: electrical control and mechanical control, which are responsible for monitoring and operating the working status of the equipment. Modern stiff boom cranes generally use automated control systems to improve the convenience and safety of operation.

2. Working principle of stiff boom crane

The working principle of stiff boom crane is relatively intuitive, and mainly depends on the coordinated work of its rigid boom, lifting system and supporting structure. The specific process is as follows:

Angle adjustment of the boom

stiff boom cranes can achieve operations with different working ranges and heights by adjusting the angle of the boom. The boom is usually of fixed length, and adjusting the angle can change the lifting height and operating radius of the load to meet different operating requirements.

Lifting and lowering of lifting loads

The crane lifts the load from the ground or water surface to a specified height through a winch and wire rope. The hydraulic device or electric drive device in the lifting system provides power to ensure smooth and efficient lifting operations.

Smooth transfer of heavy objects

In the operation process of stiff boom crane, smooth transfer of load is an important link. The crane can smoothly and safely transfer the load from the lifting position to the destination position by precisely controlling the boom angle and the action of the lifting system, avoiding tilting or falling due to improper operation.

Unloading and recovery operation

When the load reaches the predetermined position, the operator performs the unloading operation through the control system instruction. Then, the crane retracts the wire rope and prepares for the next operation.

3. Applicable scenarios of stiff boom crane

Due to its simple structure, high stability and strong load capacity, stiff boom crane is widely used in various lifting and handling tasks of heavy objects. The following are several typical application scenarios:

Ship lifting operation

stiff boom crane is widely used in ship lifting operations, especially on large ships such as cargo ships, tankers, and container ships. In ship operations, stiff boom cranes are used for lifting, unloading and transshipping operations of cargo. Due to its stable structure, stiff boom cranes can perform tasks efficiently and stably in harsh marine environments.

Port loading and unloading operations

In ports, stiff boom cranes are often used for loading and unloading containers and cargo. Due to their high load capacity and small operating space requirements, stiff boom cranes can effectively improve port operation efficiency and reduce labor costs.

Offshore platforms and offshore operations

As important lifting equipment for offshore oil and gas platforms or offshore engineering sites, stiff boom cranes are responsible for platform construction, maintenance, repair and other tasks. Their stability and corrosion resistance make them extremely reliable in offshore operations.

Engineering construction and large machinery handling

stiff boom cranes are also widely used in large-scale engineering construction, building construction and mining. They can carry large loads and are easy to operate, making them suitable for heavy object handling in various complex environments.

Logistics warehousing and heavy machinery handling

For the handling of some heavy machinery or large equipment, stiff boom cranes are often used to help quickly and efficiently complete the handling of materials. Their load capacity and accuracy can meet the needs of heavy object transportation.

4. Advantages of rigid jib cranes

Compared with other types of cranes, rigid jib cranes have the following advantages:

Simple structure and high stability

The jib of a rigid jib crane is of fixed length, which is more stable during operation and suitable for high-load and long-distance lifting operations.

Strong adaptability

Rigid jib cranes are suitable for a variety of harsh environments, including offshore platforms, ports and other places. Its sturdy structure can resist the influence of environmental factors such as high temperature and corrosion.

Large load capacity

Due to the sturdy structure of the jib, rigid jib cranes have a stronger load capacity and can handle various heavy goods.

High operational safety

Through a modern control system, rigid jib cranes can be operated accurately to ensure safety during operation and reduce accidents.

With its excellent structural design, reliable working performance and wide application fields, rigid jib cranes have become indispensable equipment for important industries such as offshore platforms, ports, and ships. With the continuous development of science and technology, rigid jib cranes in the future will have more innovations and breakthroughs in automation and intelligence, further improving the efficiency and safety of lifting operations. By deeply understanding its structure, principle and application, users can better choose crane equipment that suits their needs and promote the development and progress of the industry.
