Adjustable Side Floor Plate for Road Milling Operator Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of ground milling machines face challenges in achieving comfortable visibility and posture while operating, particularly when working alongside obstacles or in constricted spaces, as existing solutions often result in an uncomfortable inclined posture.
Innovation Solution
The introduction of an adjustable side floor plate on the operator platform that can pivot vertically between a stowed and deployed position, allowing for increased visibility and a variable standing area, which can be widened transversely to improve the operator's viewing position without compromising the machine's compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the operator leans against a fixed railing on the operator platform, then visibility along the side of the machine is improved, but the operator's posture becomes uncomfortable due to the inclined position
Solution Approach 1:
The patent applies the dynamics principle by making the operator platform floor movable rather than fixed. The floor can be tilted relative to the machine frame, allowing the operator to adjust the platform's inclination angle. This dynamic adjustment enables the operator to achieve a comfortable posture while maintaining good visibility along the side of the machine, resolving the contradiction between fixed railing visibility and operator comfort.
2Illumination intensity
If the operator platform is extended laterally to improve visibility, then the viewing position is improved, but the machine's compactness is compromised
Solution Approach 1:
The patent uses dynamics by making the operator platform floor movable and adjustable. Instead of permanently extending the platform laterally, the floor can be tilted relative to the machine frame, providing extended viewing position only when needed during operation. During transport or when compactness is required, the floor returns to its normal position, maintaining the machine's compactness while still allowing visibility improvement when required.
3Device complexity
If the operator platform floor is made stationary relative to the machine frame, then the structure is simple, but the operator cannot adjust the viewing angle comfortably
Solution Approach 1:
The patent applies dynamics by introducing movability between the operator platform floor and the machine frame. The floor can be tilted relative to the frame, allowing the operator to adjust the viewing angle and achieve comfortable posture. This dynamic capability is achieved through a relatively simple connection mechanism, balancing structural simplicity with operational flexibility.

AI summary
A self-propelled ground milling machine, in particular a road milling machine, a stabilizer or a recycler, comprising a machine frame borne by traveling devices, a ground milling device mounted on the machine frame having a milling drum box and a milling drum which can be rotated within the milling drum box about a rotation axis running transverse to a main working direction of the ground milling machine, and an operator platform from which the ground milling machine is operated by an operator, having an operator platform floor on which the operator can stand while operating the ground milling machine, having a main floor plate. What is now essential according to the invention is that, in addition to the main floor plate, a side floor plate is provided which can be pivoted about a vertical axis or can be adjusted along a horizontal adjustment axis, and by means of which the standing area of the operator platform can be varied.
