Integrated Lifting Unit in Work Machine Cab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machine cabs require cumbersome and expensive mounting processes due to heavy lifting units and complex structural requirements, limiting payload capacity and applicability in space-constrained environments.
Innovation Solution
The lifting unit is integrated into the wall structure of the work machine cab, simplifying manufacturing and mounting by eliminating the need for separate support structures, allowing for reduced space usage and enabling a window opening for improved ergonomics and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy lifting units with separate support structures are used to stabilize vertical movement, then the lifting unit can provide sufficient structural support, but the payload capacity of the truck is reduced
Solution Approach 1:
The lifting unit is integrated into the wall structure of the work machine cab, merging the lifting function with the cab's structural framework. This eliminates the need for separate heavy support structures, reducing overall weight while maintaining structural support capability.
Solution Approach 2:
The wall structure serves dual purposes: it provides the structural framework of the cab and simultaneously functions as the lifting unit. This multi-functionality reduces the need for additional dedicated lifting components, thereby reducing weight.
2Reliability
If complex mounting procedures with multiple working steps are used to attach the lifting unit, then the lifting unit can be securely attached, but the mounting cost becomes expensive
Solution Approach 1:
The lifting unit and wall structure are manufactured as an integrated assembly, combining multiple components into a single unit. This eliminates the need for complex field mounting procedures, reducing mounting time and cost while maintaining secure attachment.
Solution Approach 2:
The lifting unit is pre-integrated into the wall structure during manufacturing, performing the mounting action in advance. This preliminary integration simplifies final installation to a straightforward attachment process, reducing mounting complexity and cost.
3Stability of the object's composition
If lifting units are arranged in all cab corners or with frame portions on several sides, then the vertical movement of the cab is stabilized, but the applicability to space-limited work machines is limited
Solution Approach 1:
The lifting function is extracted from the traditional multi-point support configuration and concentrated into a single integrated wall structure. This simplification reduces spatial requirements while maintaining stability through the integrated design.
Solution Approach 2:
The lifting unit utilizes the vertical dimension of the wall structure, leveraging the height of the cab wall to provide stable lifting without requiring extensive horizontal space. This dimensional approach enables stability in space-constrained applications.

AI summary
The present invention relates to a work machine cab (1) comprising wall, floor and roof structures enclosing a cabin space (3). This work machine cab is movable vertically by a lifting unit (4) attached with securing means (5) to a loader, for instance. The lifting unit (4) comprises at least one guide bar (8) integrated with a side wall (7) so as to control the movement of the work machine cab (1), and a control means (10) arranged in the guide bar. The operation of the lifting unit (4) is controlled by at least one actuator (11) so as to produce a mutual movement between the control means and the guide bar.
