Load Height Detection System and Method - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240010475 titled 'Load Height Detection System and Method

Simplified Explanation

The patent application describes a load height detection system for a crane that has a load space and multiple booms. The crane includes a grapple tool attached to the boom tip, which provides sensor data for open/close status. The system also includes a controller that interprets positioning data of the crane and boom tip to determine if the boom tip is inside or outside the load space, and to identify loading or unloading operations based on changes in boom tip height.

  • The load height detection system is designed for cranes with multiple booms and a grapple tool for handling cargo.
  • The grapple tool provides sensor data for open/close status, allowing the system to determine if the cargo is being loaded or unloaded.
  • The system includes a controller that receives positioning data of the crane and boom tip, and interprets the data to identify the position of the boom tip relative to the load space.
  • The controller also determines if the boom tip is inside or outside the load space, and identifies loading or unloading operations based on changes in boom tip height.
  • The system is able to accurately determine if the load space is fully loaded or fully unloaded based on the final position of the boom tip.

Potential applications of this technology:

  • Construction industry: The load height detection system can be used in construction cranes to ensure accurate loading and unloading of materials at different heights.
  • Shipping industry: Cranes used in ports and shipping yards can benefit from this system to efficiently load and unload cargo from ships.
  • Warehousing and logistics: The system can be implemented in cranes used in warehouses and distribution centers to improve the efficiency and safety of loading and unloading operations.

Problems solved by this technology:

  • Accurate load height detection: The system solves the problem of accurately determining the position of the boom tip relative to the load space, ensuring efficient and safe loading and unloading operations.
  • Identification of loading/unloading operations: The system solves the problem of identifying whether the crane is in a loading or unloading operation based on changes in boom tip height, allowing for better control and coordination of the process.

Benefits of this technology:

  • Improved efficiency: The load height detection system allows for more precise and efficient loading and unloading operations, reducing time and effort.
  • Enhanced safety: Accurate positioning and identification of loading/unloading operations minimize the risk of accidents and damage to the cargo or equipment.
  • Increased productivity: The system enables faster and more streamlined loading and unloading processes, leading to increased productivity and throughput.


Original Abstract Submitted

a load height detection system having a load space, a crane comprising multiple booms and a boom tip. a grapple tool is adapted to handle cargo, being attached to the boom tip, and is adapted to provide sensor data for open/close status. the crane has a vertical slew angle, a rotational angle, a horizontal distance of the boom tip to the base of the crane and a height position of the boom tip relative to the load space. a controller receives the positioning data of the crane and the boom tip, the controller being adapted to interpret the data of the vertical slew angle, the rotational angle, the distance and the height data to identify if the boom tip is inside or outside the load space, and to identify a loading or an unloading operation by an increasing or decreasing boom tip height in the area of the load space at a final position, the final position being defined by an open/close status of the grapple tool, and determining a fully loaded or fully unloaded load space.
