Work Machine Leader Transport Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machines face challenges in transporting machines of the same type efficiently, as removable attachments often need to be transported separately, increasing transport effort and costs, or remain on the leader during transport, which raises transport dimensions.
Innovation Solution
A work machine design that allows the leader and removable attachment to be transported together without significantly increasing transport dimensions, by pivotably mounting the leader on the upper carriage and providing receiving means on the leader for mounting the removable attachment in a transport position at the rear or side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the removable attachment is transported separately, then the transport dimensions of the basic unit are reduced, but the transport effort and associated costs increase
Solution Approach 1:
The removable attachment is mounted on the rear side of the leader in the transport position, nesting it within the space already occupied by the leader structure. This allows the attachment to be transported together with the basic unit without significantly increasing the overall transport dimensions, while eliminating the need for separate transport operations.
2Loss of time
If the removable attachment remains on the leader for transport, then the transport effort is reduced, but the transport dimensions, particularly the transport height, are increased
Solution Approach 1:
Instead of mounting the removable attachment on the front side of the leader (which would increase transport height when the leader is pivoted backward), the attachment is mounted on the rear side of the leader. This repositioning in the longitudinal dimension allows the attachment to be accommodated within the transport envelope without significantly increasing the transport height, as the leader pivots backward into a compact configuration.
3Ease of operation
If the removable attachment is mounted on the front side of the leader, then it is accessible in operation, but it cannot be mounted for transport on the rear side due to leader kinematic system constraints
Solution Approach 1:
The leader is designed with receiving means on both the front side and the rear side, enabling the removable attachment to be mounted in different positions depending on the operational requirements. The front side mounting provides accessibility during operation, while the rear side mounting enables compact transport configuration. This multi-functional design allows the same leader structure to accommodate different mounting configurations without requiring separate specialized structures.

AI summary
The disclosure relates to a work machine comprising a mobile undercarriage, an upper carriage, a leader mounted on the upper carriage, and an attachment, wherein the leader is pivotably mounted on the upper carriage by means of a leader kinematic system and wherein the removable attachment can be mounted in an operating position on a front side of the leader facing away from the upper carriage. According to the disclosure, the removable attachment can be removed from the front side of the leader and the leader comprises receiving means via which the removable attachment can be mounted for transport on a rear side of the leader facing the upper carriage or laterally on the leader in a transport position.
