Automated Crane Piloting Optimizing Rotation to Minimize Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing tower cranes on a construction site where some cranes have staggered working phases poses challenges in ensuring safe operation and productivity, particularly when cranes cannot weathervane if other cranes are still active, leading to inefficient automated piloting and difficulty in prioritizing crane movements to avoid collisions.
Innovation Solution
An automated piloting method for tower cranes that determines an optimal destination configuration aligning with the wind direction to minimize interference, optimizes the path to reach this configuration, and adjusts rotation direction to cut the fewest interference lenses, while prohibiting other cranes from accessing these areas and waiting for working cranes to release interference lenses, ensuring safe operation and maintaining site productivity.

1Reliability
If automated piloting process is implemented to allow crane operators to leave their cranes safely, then safety is improved, but the process requires a lot of travel for cranes in automated piloting making it difficult to manage priorities
Solution Approach 1:
The system changes the parameters of crane movement by optimizing the path between initial and final configurations. It determines the direction of rotation that cuts the fewest interference lenses, thereby reducing unnecessary travel distance while maintaining safety. This parameter optimization allows cranes to reach their destination configurations more efficiently without compromising safety protocols.
Solution Approach 2:
The system dynamically adjusts crane operations by optimizing paths in real-time based on the positions and movements of other cranes. It determines optimal rotation directions and waits for working cranes to release interference lenses dynamically, allowing the automated piloting crane to proceed when safe. This dynamic adaptation reduces idle travel time while maintaining safety.
2Object-generated harmful factors
If cranes are positioned to align with wind direction to minimize interference, then interference is reduced, but path optimization becomes more complex
Solution Approach 1:
The system changes the orientation parameter of the crane by determining a destination configuration where the mobile assembly extends in a direction corresponding as close as possible to the wind direction. This parameter adjustment minimizes interference with other cranes while the system manages the complexity through automated path optimization algorithms that calculate the best rotation direction.

AI summary
The invention relates to an automated control method (S) of a set (1) of cranes (2, 3, 4) comprising the following steps: - determine (S2) a destination configuration of the crane in automated control, - determine (S3) whether, starting from its initial spatial configuration, the crane in automated control is able to reach the final configuration regardless of its direction of rotation (A, B), - if so, determine (S4) the interference lenses of this crane with the other cranes of the set and identify the direction of rotation (A, B) of the crane in automated control in which said crane cuts the fewest interference lenses, - deduce (S6) the direction of rotation (A, B) in which the crane (2) in automated control must be moved angularly to reach the final configuration.
