Column

The column supports and fixes the swivel arm of the column jib crane. The column jib crane adopts single-row tapered roller bearings to withstand radial force and axial force, which ensures the stability and safety of the column jib crane.

Key Features & Advantages:

  • Utilizes single-row tapered roller bearings for enhanced durability
  • Withstands both radial and axial forces for superior stability
  • Ensures safe operation even under heavy load conditions
  • Provides a solid foundation for the entire crane system

Swivel Arm

The swivel arm is welded by the combination of I-beam. The swivel arm allows the electric or manual trolley to move horizontally, and also allows the electric hoist to lift up and down and rotate around the column. The design of the swivel arm makes the column jib crane more flexible and efficient.

Key Features & Advantages:

  • Allows electric or manual trolley movement along its length
  • Enables hoist lifting and 360-degree rotation around column
  • I-beam construction provides exceptional strength-to-weight ratio
  • Designed for flexibility and efficiency in material handling

Support Arm

The support arm can support the swivel arm and increase the bending resistance and strength of the swivel arm.

Key Features & Advantages:

  • Provides additional structural support to the swivel arm
  • Significantly increases bending resistance and load capacity
  • Enhances overall crane stability and safety
  • Works in conjunction with the reducer for smooth operation

Redutor

The roller is driven by the reducer to realize the electric slewing of the jib. The combination of support arm and reducer makes the slewing function of the column jib crane more stable and reliable.

Key Features & Advantages:

  • Enables precise electric slewing function with smooth operation
  • Works with support arm for enhanced stability during rotation
  • Ensures reliable and consistent rotation performance
  • Reduces maintenance requirements through durable design

Electric Chain Hoist

Electric chain hoist is the key component of the column jib crane to lift heavy objects and move horizontally along the swivel arm. The electric chain hoist can work efficiently and move horizontally and vertically to meet the needs of various lifting operations.

Key Features & Advantages:

  • Lifts and moves heavy objects efficiently with precise control
  • Operates smoothly in both horizontal and vertical directions
  • Adaptable to various lifting operations and load requirements
  • Energy-efficient design reduces operational costs
  • Safety features prevent overload and ensure secure lifting

Electric Part

The electric part adopts C-rail plus flat cable power supply system, low voltage inter-control type safety voltage for operation. Hand electric door push button to realize the control of the column jib crane, including the fast rise, fast fall, slow rise, slow fall of the electric chain hoist, as well as the walking of the hoist running trolley and the left and right slewing of the column jib crane. The collector ring inside the column provides electricity to make the swivel arm rotate arbitrarily. The collector ring ensures the safe and reliable operation of the column jib crane.

Key Features & Advantages:

  • C-rail plus flat cable power supply system for reliable electricity transmission
  • Low voltage inter-control safety system protects operators
  • Collector ring enables unlimited 360-degree rotation without cable winding
  • Hand-held push button station allows intuitive control of all functions
  • Safety features include emergency stop and overload protection

FAQ about Parts of a Column Jib Crane

Q1: What are the main components that make up a column jib crane?
A1: The primary parts of a column jib crane include the column, the swivel arm, the support arm, the reducer, the electric chain hoist, and the electrical components. Each of these jib crane parts plays a critical role in ensuring the crane's stability, rotation, lifting capacity, and safe operation.

Q2: Can components like the electric chain hoist be replaced or upgraded on an existing column jib crane?
A2: Yes, one of the advantages of standard jib crane parts is their modularity. Key components like the electric chain hoist or the reducer can typically be replaced or upgraded to enhance performance or adapt to new requirements, provided the new parts are compatible with the existing column jib crane structure.

Q3: Which part of a column jib crane requires the most frequent maintenance?
A3: While maintenance schedules depend on usage, the electric chain hoist and the reducer often require more regular checks as they contain moving parts and mechanical drives. However, all jib crane parts, including the swivel arm bearings and electrical components, should be inspected periodically to ensure the entire column jib crane system's longevity and safety.

Q4: Is the swivel arm on a column jib crane manually or electrically operated?
A4: The operation of the swivel arm can vary by model. Many modern column jib cranes feature an electric slewing system powered by the reducer, allowing for effortless rotation. However, some lighter-duty models may have a manually operated swivel arm. The electric chain hoist that travels along it, however, is typically always electrically powered.

Q5: How do the electrical components contribute to the safety of a column jib crane?
A5: The electrical components are vital for safety. They include the control system, limit switches, and the collector ring. These jib crane parts work together to provide features like overload protection, controlled movement for the electric chain hoist, and safe power transmission during the swivel arm's rotation, ensuring the reliable and secure operation of the column jib crane.

Conclusão

By analyzing the various parts of a column jib crane—from the robust column and versatile swivel arm to the powerful electric chain hoist and precise electrical components—we can see how each part plays a critical, interconnected role in delivering a highly efficient and reliable lifting solution.
