Description

The fixed port cargo lifting crane, a symbol of reliability, is a crane that is fixed on the basis of the port or supported on the pedestal. It can only work in situ, but its main purpose is to handle the loading and unloading of port goods. It is a dependable tool for carrying out cargo transfers between shores and ships or between different cargo ships.

Structure and function

Fixed Port Cargo Lifting Cranes are usually composed of a lifting mechanism, a running mechanism, a luffing mechanism, a slewing mechanism, and other auxiliary mechanisms; the following is a specific introduction:

Lifting mechanism

Composition: It is mainly composed of a driving device, reel, wire rope, pulley block hook, and other components.
Function: Realize the vertical lifting movement of goods, which is one of the most important working mechanisms of the crane. The drum is driven to rotate through the driving device so that the wire rope is wound or released so as to drive the hook to rise or fall to complete the lifting and lowering operation of the goods.

Running Mechanism
Composition: Including drive motor, reducer, brake, wheel, and other components.

Function: It is divided into a large car running mechanism and a small car running mechanism. The trolley running mechanism is used to realize the overall movement of the crane along the port track to change the operating position of the crane. The trolley running mechanism makes the trolley installed on the bridge frame move along the bridge track so as to realize the lateral movement of the goods in the horizontal direction and cooperate with the lifting mechanism to accurately lift the goods to the designated position.

Luffing mechanism
Composition: It is generally composed of luffing drive device, luffing wire rope, boom system, etc.

Function: Change the amplitude of the boom, that is, the horizontal distance from the end of the boom to the center of rotation of the crane. Through the luffing mechanism, the crane can be operated under different working radii to adapt to the loading and unloading needs of goods in different positions and improve the working range and flexibility of the crane.

Slewing mechanism
Composition: It is mainly composed of a slewing bearing, slewing driving device, slewing platform, etc.
Purpose: The superstructure of the crane is rotated relative to the lower fixed part, which can usually achieve 360° full rotation. In this way, the crane can carry out the lifting operation of goods in a large circumference range, and the operation coverage of the crane is expanded.

Other ancillary agencies
Composition: including electrical control system, safety protection device, lubrication system, lighting system, etc.
Function: The electrical control system is used to control the operation of various mechanisms and realize various actions and functions of the crane. Safety protection devices, such as limit switches, overload protection devices, windproof devices, etc., are used to ensure the safe operation of the crane and prevent accidents. The lubrication system provides lubrication for all moving parts, reduces wear, and prolongs the service life of the equipment. The lighting system provides illumination for the crane to operate at night or in low-light conditions.

Fixed port cargo lifting crane have significant advantages in port cargo handling operations

High efficiency

Strong lifting capacity: Stationary port cranes usually have a large lifting capacity, generally up to tens of tons or even hundreds of tons. They can easily lift large containers, heavy machinery and equipment, and other goods, greatly improving the efficiency of loading and unloading.

Fast operation cycle: Each mechanism of the stationary port crane operates at a high speed. The lifting mechanism can quickly lift the goods, the luffing mechanism and the slewing mechanism can rapidly adjust the operating position. This enables the rapid grabbing, handling, and unloading of goods, shortens the time of a single operation cycle, and thus improves the overall loading and unloading efficiency.

Stability

Sturdy structural design: Stationary port cranes are constructed with a robust metal structure and are firmly installed on a fixed foundation. They are capable of withstanding harsh marine environments and strong wind conditions, ensuring the safety of operations.

Precise positioning control: Stationary port cranes are equipped with advanced electrical control systems and high-precision sensors. These enable them to achieve the utmost precision in the lifting and positioning of goods. This precision significantly reduces the risk of cargo damage during loading and unloading operations.

Flexibility

Wide range of operation: Thanks to the luffing and slewing mechanisms, stationary port cranes can operate within a large spatial range. They can cover different areas of the port terminal, meeting the diverse loading and unloading needs of goods in various positions, thereby enhancing the versatility and flexibility of the equipment.

Multiple operation modes: Stationary port cranes have a variety of operation modes and functions. These can be adjusted according to different types of cargo, such as containers, heavy machinery, and bulk goods. They can also adapt to different operating environments, including those with high winds and limited space, and meet the corresponding loading and unloading requirements.

Durability

High-quality materials and manufacturing processes: The key components of fixed port cargo lifting cranes are typically made of high-strength, wear-resistant materials. Through rigorous processing and assembly procedures, they possess high strength and reliability. These cranes can endure frequent heavy-duty operations and harsh environments, have a long service life, and reduce the frequency of equipment replacement and maintenance.

Comprehensive maintenance system: Due to the importance and complexity of stationary port cranes, a comprehensive maintenance system is usually established. Regular inspections, maintenance, and repairs are carried out on the equipment. Problems are promptly identified and addressed to maintain optimal equipment performance and extend its service life.

Economical

Long-term cost-effectiveness: Although the initial investment in stationary port cranes is substantial, due to their high efficiency, stability, and durability, they can achieve high production efficiency during long-term use. This reduces the cost of loading and unloading per unit of cargo. Meanwhile, the lower need for repairs and replacements also cuts down on operating costs.

Improve port operation efficiency:

The efficient operation of stationary port cranes can accelerate the turnover of goods and increase the port's throughput capacity, thereby bringing more economic benefits to the port. In addition, it can also reduce the time ships spend in port for loading and unloading, lower the port's operating costs, and enhance the port's competitiveness.
