Cranes are indispensable in industrial and port operations, with various types designed for specific needs. Among them, fixed cranes and rail-mounted cranes have unique features that cater to different applications. Here’s a detailed comparison:
Structure and Installation
Fixed Cranes
Fixed cranes are installed in a specific location, secured to the ground using anchor bolts or similar methods. Typically mounted on a stable foundation, these cranes offer exceptional stability. Their operational range is limited to the area covered by the boom's rotation and length, making them ideal for tasks requiring repetitive operations within a fixed radius.
Rail-Mounted Cranes
Rail-mounted cranes, such as container gantry cranes, operate on tracks laid along the port or site. Equipped with wheels and a drive system, they can traverse along predetermined paths. These cranes feature a more complex design, incorporating systems to ensure stability and smooth movement on rails. In addition to standard lifting and rotating mechanisms, they include travel motors, reducers, and wheels.
Work Range and Flexibility
Fixed Cranes
While highly efficient within their operational range, fixed cranes are limited to their installed location. They are best suited for tasks in smaller areas where mobility is unnecessary. However, repositioning a fixed crane requires significant effort and time.
Rail-Mounted Cranes
These cranes are designed for flexibility. By moving along tracks, they cover a wider operational area, making them ideal for ports and large industrial zones. For example, rail-mounted container cranes can work along an entire quay, accessing multiple ships and storage areas efficiently. This mobility enhances operational versatility and improves resource utilization.
Choosing the Right Crane
Fixed cranes are perfect for repetitive tasks within a confined area, while rail-mounted cranes excel in operations requiring mobility across extensive regions. SEVENCRANE offers a wide range of tailored solutions to meet your specific material handling needs.
