Crane Obstacle Sensor Front Rear Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing obstacle detection systems for cranes fail to provide a sufficient detection range during both traveling and operation, as the attitudes and collision patterns differ significantly, leading to inadequate monitoring and collision prevention, especially during turns and swiveling.
Innovation Solution
The implementation of obstacle sensors with detection ranges from front to rear and rear to front, strategically positioned to cover lateral sides of the crane's traveling and swivel bodies, allowing for comprehensive obstacle detection during both traveling and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a first camera and a second camera are provided to detect obstacles during traveling, then obstacle detection capability is improved, but detection range during operation remains insufficient
Solution Approach 1:
The obstacle detection system is segmented into multiple sensor units with different detection directions. Obstacle sensors are provided at both the front and rear of the crane body, with each sensor having a specific detection range oriented toward different areas. This segmentation allows the system to cover various collision patterns during both traveling and operation phases.
Solution Approach 2:
The detection system dynamically adapts to different operational states of the crane. During traveling, the front obstacle sensor detects obstacles in the forward direction, while during operation, the rear obstacle sensor detects obstacles that may collide with the rear part of the crane body. This dynamic adaptation ensures sufficient detection range regardless of the crane's operational phase.
2Reliability
If obstacle sensors are positioned to cover lateral sides during traveling, then detection during traveling is improved, but blind spots during swiveling remain
Solution Approach 1:
The system merges the detection coverage of front and rear obstacle sensors to eliminate blind spots. The front obstacle sensor detects obstacles in front of the crane body, while the rear obstacle sensor detects obstacles at the rear. Together, these sensors provide comprehensive coverage that eliminates detection gaps during swiveling operations, ensuring continuous obstacle detection capability.
Solution Approach 2:
The detection system extends coverage to multiple spatial dimensions by positioning sensors at both front and rear of the crane body. This multi-dimensional arrangement ensures that obstacles regardless of their position relative to the crane body are detected, covering lateral sides during traveling and eliminating blind spots during swiveling operations.

AI summary
Provided is a crane that can detect obstacles within a sufficient range while traveling and while doing work. A crane that is provided with an obstacle sensor that, during travel, detects the approach of obstacles toward a front side part of a travel body and, during work, detects the approach of obstacles toward a rear side part of a turning body. According to a first embodiment, the obstacle sensor has a detection range that is directed from front to rear. According to a second embodiment, the obstacle sensor has a detection range that is directed from rear to front.
