Crane Fly Jib With Remote Rotation And Telescoping Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fly jibs lack a rotation mechanism and the ability to extend their length, requiring manual rotation and crane movement to align loads with target areas, which is inefficient and hazardous.
Innovation Solution
A fly jib with a variable length beam, rotation mechanism, and balance mechanism that allows selective rotation and extension, controlled remotely using a radio control system, maintaining horizontal balance through a chain drive mechanism and counterweight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fly jib is designed without a rotation mechanism, then the device complexity is reduced, but the ease of operation deteriorates as manual rotation using long poles is required
Solution Approach 1:
The rotation mechanism is integrated into the fly jib structure, allowing it to rotate autonomously under remote control without requiring external manual intervention. The system serves itself by incorporating the rotation capability directly into the device, eliminating the need for separate manual rotation operations.
Solution Approach 2:
The manual mechanical rotation system using long poles is replaced with an automated rotation mechanism that can be controlled remotely. This substitution eliminates the need for manual mechanical manipulation and improves operational convenience while maintaining structural simplicity.
2Device complexity
If a fly jib is designed without an extension mechanism, then the device complexity is reduced, but the productivity deteriorates as the crane must be moved to reposition loads
Solution Approach 1:
The fly jib incorporates a telescoping mechanism that allows it to dynamically change its length. The beam can extend and retract based on operational requirements, enabling the load to be positioned at different distances from the crane without moving the crane itself, thereby improving productivity.
Solution Approach 2:
The fly jib is designed with multi-functionality, combining both rotation and extension capabilities into a single device. This universal design allows the fly jib to perform multiple functions (rotating and extending) that would otherwise require separate mechanisms or crane movements, thus improving operational efficiency.
3Device complexity
If manual rotation is used to align the load, then the device complexity remains low, but the safety deteriorates due to manual handling of heavy components
Solution Approach 1:
The rotation mechanism is integrated into the fly jib structure, allowing it to rotate autonomously under remote control without requiring external manual intervention. The system serves itself by incorporating the rotation capability directly into the device, eliminating the need for separate manual rotation operations.
Solution Approach 2:
The manual mechanical rotation system using long poles is replaced with an automated rotation mechanism that can be controlled remotely. This substitution eliminates the need for manual mechanical manipulation and improves operational convenience.
4Adaptability or versatility
If the fly jib beam is made variable length, then the adaptability is improved for different target areas, but the device complexity increases due to telescoping mechanisms
Solution Approach 1:
The fly jib incorporates a telescoping mechanism that allows it to dynamically change its length. The beam can extend and retract based on operational requirements, enabling the load to be positioned at different distances from the crane without moving the crane itself, thereby improving productivity.
Solution Approach 2:
The fly jib beam is divided into multiple telescoping sections that can extend and retract independently. This segmentation allows the beam to achieve variable lengths while maintaining a compact form when retracted, balancing adaptability with structural simplicity.

AI summary
A fly jib for a crane having a load block includes a variable length beam to which a load can be connected. A rotation mechanism is connected to the variable length beam, and is connectable to the load block so that said rotational mechanism can selectively rotate the variable length beam with respect to the load block. A balance mechanism is connected to the variable length beam, the balance mechanism automatically keeps the variable length beam in a horizontal position.
