Crane Operating Unit Pivoting Support for Cab Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of cranes must frequently change positions within the driving cab to operate the crane, increasing the time and reducing comfort while switching between steering the vehicle and operating the crane.
Innovation Solution
A support arrangement for the operating unit that allows limited movable positions, enabling the operator to control the crane from the driving seat by pivoting or displacing the unit between a working position between the steering arrangement and driving seat, and a storage position away from it, along with a visualization unit for enhanced visibility of the working environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating unit is stationarily mounted at the passenger seat, then the operating unit is stable and easily accessible, but the operator must move from the driving seat to the passenger seat to operate the crane, increasing the time and reducing comfort
Solution Approach 1:
The support arrangement is made dynamically movable between a storage position (where the operating unit is moved away from the steering arrangement) and a working position (where the operating unit is between the steering arrangement and driving seat). This allows the operator to access the operating unit while remaining at the driving seat, eliminating the need to move to the passenger seat and reducing position change time.
2Ease of operation
If the operating unit is moved to be between the steering arrangement and driving seat, then the operator can operate the crane from the driving seat, but the operating unit interferes with the steering arrangement
Solution Approach 1:
The support arrangement enabling the operating unit to move between working and storage positions allows dynamic positioning. When not in use or when steering is required, the operating unit can be moved to the storage position away from the steering arrangement, eliminating interference. When crane operation is needed, it moves to the working position between the steering arrangement and driving seat.
3Adaptability or versatility
If the operating unit is frequently moved between positions, then the operator can switch between steering and crane operation, but the support arrangement becomes more complex
Solution Approach 1:
The support arrangement is divided into multiple parts that are pivotable relative to each other. The first part supports the operating unit and the mounting arrangement is arranged on the second part. This segmentation allows the operating unit to be moved between positions through coordinated pivotal movements of the parts, achieving position switching while maintaining a manageable structural complexity through modular design.

AI summary
A crane control for a crane includes at least one operating unit operable by an operator for controlling working functions of the crane. Control signals can be input to actuators of the crane by the operating unit, and a mounting arrangement is provided for mounting the operating unit in a driving cab of the vehicle and a support arrangement connects the operating unit to the mounting arrangement. The support arrangement for the operating unit is supported limitedly moveably between at least two positions, a first position of which is in the form of a working position in which the operating unit is between a steering arrangement of the vehicle and a driving seat, and a second position of which is in the form of a storage position in which the operating unit is moved away from the steering arrangement of the vehicle.
