Crane Silo Shield Support Segmented Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crane silos for transporting loose building materials like concrete, gravel, and sand are heavy, difficult to maintain, and costly to produce, while maintaining reliable strength and operational efficiency.
Innovation Solution
The design incorporates shield-shaped support elements attached to the container's circumference, connecting to a frame part near the ground, allowing for pivotable mounting of the outlet chute and a recessed frame part for improved stability, accessibility, and reduced weight, along with a flap closure mechanism for efficient discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional welded construction is used for crane silos, then reliable strength values are achieved, but dead weight increases and manufacturing costs rise
Solution Approach 1:
The container is divided into an upper container section and a lower container section that are connected in a telescopically separable manner rather than being permanently welded together. This segmentation allows the sections to be joined and disconnected as needed, reducing the overall dead weight while maintaining strength during operation. The separable connection eliminates the need for heavy permanent welds between the entire container structure and support frame.
Solution Approach 2:
The connection between the container sections and the support frame is made dynamically adjustable through separable connections that can be assembled and disassembled. This dynamic connection system allows the crane silo to be configured based on operational requirements, reducing dead weight by only connecting components when needed rather than maintaining permanent rigid connections throughout the entire structure.
2Strength
If traditional crane silo design is used, then reliable strength values are achieved, but ease of manufacture decreases and manufacturing costs increase
Solution Approach 1:
The container is segmented into upper and lower sections that can be manufactured separately and then assembled through telescopic connection. This segmentation simplifies manufacturing by allowing each section to be produced independently using standard fabrication processes, reducing the complexity and cost of manufacturing while maintaining structural integrity through the separable connection system.
Solution Approach 2:
The dynamic, separable connection system between the container and support frame simplifies manufacturing by eliminating the need for complex permanent welding operations. The components can be manufactured to standard specifications and then assembled using simpler connection mechanisms, reducing manufacturing complexity and cost while maintaining reliable strength values during operation.
3Device complexity
If outlet chute is fixed in position, then structural simplicity is maintained, but accessibility for cleaning and maintenance decreases
Solution Approach 1:
The outlet chute is designed with pivotable mounting that allows it to be rotated or adjusted to different positions. This dynamic positioning capability enables the chute to be moved into accessible positions for cleaning and maintenance while maintaining a simple overall structure. The pivotable connection allows easy access to the chute interior without requiring complex disassembly procedures.

AI summary
Crane silo (1) for transporting bulk building materials such as concrete, gravel, sand, or the like, comprising a container (2) designed to hold a building material, which is attached to a stopable support frame (3) and has at an upper end a filling opening (5) for filling the container (2) and at a lower end, which tapers in a funnel-like manner in the emptying direction, a discharge opening (6) for removing the building material, wherein an actuable closure device (7) for determining the quantity of building material to be removed is arranged adjacent to the discharge opening (6) of the container (2), wherein the container (2) is connected in a transition area (15) formed by the container section (14) which tapers towards the discharge opening (6) and a cylindrical upper container section (13) which is uniformly connected to the latter, by means of a clamp attached to the outer circumference of the container (2). (2) distributed,shield-shaped support elements (16, 17) are connected to a frame part (18) forming the ground-level end of the support frame (3).
