Uvod
Mobile jib cranes are versatile lifting devices designed for various industrial applications. Their mobility and flexibility make them an excellent choice for environments where fixed cranes are impractical. Understanding the structure and features of mobile jib cranes is essential for maximizing their benefits in material handling tasks.
Struktura
Base:
The base is the foundation of the premično dvigalo, typically equipped with wheels or casters for easy movement. The wheels can be either fixed or swivel, allowing for maneuverability in different directions. Some models feature locking mechanisms to secure the crane in place during operation.
Pillar (Column):
The vertical pillar supports the jib arm and connects to the base. It is usually made of robust steel to handle heavy loads and ensure stability. The pillar height can vary depending on the crane's design and intended use.
Jib Arm:
The jib arm is the horizontal beam that extends from the pillar. It can rotate around the pillar, providing a wide working radius. The arm typically features a trolley or hoist that moves along its length to position the load precisely. The jib arm’s length and rotation angle can vary, with some models offering up to 360-degree rotation.
Trolley and Hoist:
The trolley travels along the jib arm and carries the hoist, which lifts and lowers the load. The hoist can be electric or manual, depending on the application. The trolley’s movement along the jib arm allows for precise placement of loads within the crane’s working radius.

Features
Mobility:
The primary feature of premični žerjavi is their mobility. Equipped with wheels or casters, these cranes can be easily moved to different locations within a facility. This flexibility makes them ideal for tasks that require lifting and moving materials across various workstations.
Versatility:
Mobile jib cranes are highly versatile, capable of handling a wide range of lifting tasks. They are used in manufacturing, warehousing, maintenance, and construction environments. Their ability to move loads efficiently and safely enhances productivity and reduces the need for manual labor.
Ease of Use:
These cranes are designed for ease of use, with intuitive controls and simple operation. They can be quickly positioned and adjusted to suit different tasks, making them user-friendly for operators.
Safety:
Mobile jib cranes are equipped with safety features such as overload protection, emergency stops, and locking mechanisms to secure the crane during operation. These features ensure the safe handling of loads and protect operators from potential hazards.
Zaključek
Mobile jib cranes are valuable tools for various material handling applications, offering mobility, versatility, ease of use, and safety. Understanding their structure and features helps in selecting the right crane for specific tasks and maximizing their operational efficiency.
