Dual-Operator Cabin Work Machine for Narrow Space Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current work machines, such as mobile cranes, face challenges in maneuvering in narrow spaces due to limited operator visibility and the need to change positions during rear movement, and they often require additional chassis support, which increases weight and restricts cargo capacity and lifting capabilities.
Innovation Solution
A work machine with dual operator cabins on both sides, allowing operators to drive without changing positions, combined with a high-capacity crane system featuring shortened boom arms for close-range cargo handling and a monobloc chassis for single-chassis cargo support, enabling efficient cargo transport in restricted areas without the need for additional support feet or elevated boom operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile crane is used for carrying goods, then easy transport and practical use are improved, but operator visibility is limited and rear manoeuvre becomes dangerous
Solution Approach 1:
The vehicle is divided into two separate operator cabins positioned at the front and rear of the chassis. This segmentation allows each operator to independently control the vehicle from their respective positions, eliminating the visibility limitations of a single-cab design while maintaining the practical ease of transport.
2Power
If additional chassis is used to carry crane system, then crane capacity is improved, but vehicle weight increases
Solution Approach 1:
The crane system is merged with the vehicle chassis, forming an integrated structure where the crane boom and lifting mechanism are mounted directly on the main chassis. This eliminates the need for additional separate chassis, reducing overall vehicle weight while maintaining high crane capacity for lifting precast members and panels.
3Adaptability or versatility
If crane with long boom arm is used, then scanning area is improved, but vehicle height increases
Solution Approach 1:
The crane boom is designed with dynamic articulation capabilities, allowing it to extend and position loads horizontally without requiring excessive vertical height. The boom can articulate and rotate to achieve broad scanning areas and cover wide working radii while maintaining a compact vehicle profile suitable for tunnel and narrow space operations.
4Ease of operation
If operator changes sitting position for rear manoeuvre, then vehicle control is improved, but operation complexity increases
Solution Approach 1:
The vehicle control system is segmented into two independent operator cabins, one at the front and one at the rear. Each cabin is equipped with complete control systems, allowing the operator to control vehicle movement and crane operations from either position without needing to physically relocate, thereby simplifying operational procedures.
