V-Shaped Lifting Rocker for Inloader Payload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing inloaders face challenges in increasing the permissible loading weight and improving force introduction due to the weight and limited stroke of the lifting arms, which restricts the ability to pick up transport frames efficiently, especially when transporting large or bulky goods like flat glass.
Innovation Solution
The lifting rocker is designed with two arms tapering at an acute angle towards the saddle plate, connected via a crossbeam and equipped with pneumatic or hydraulic cylinders, allowing for better force distribution and weight reduction, enabling a lighter and more stable construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional parallel lifting rocker arms are used, then structural stability is maintained, but the permissible loading weight is limited and force introduction is insufficient
Solution Approach 1:
The lifting rocker arms are designed to converge at an acute angle towards the saddle plate instead of running parallel, creating an asymmetric V-shaped configuration. This asymmetric design improves force introduction and increases the permissible loading weight while maintaining structural stability through the triangular geometry formed by the converging arms and crossbeam.
2Stability of the object's composition
If heavy construction is used for the lifting rocker, then structural stability is improved, but the weight increases reducing payload capacity
Solution Approach 1:
The lifting rocker is segmented into two separate converging arms connected by a crossbeam, forming a triangular structure. This segmentation allows the structure to achieve high stability through geometric triangulation while using thinner, lighter individual components compared to a solid heavy construction, thereby reducing overall weight while maintaining structural integrity.
3Productivity
If the lifting arms have limited stroke, then the device complexity is reduced, but the ability to pick up transport frames efficiently is restricted
Solution Approach 1:
The lifting rocker arms are designed with pivot connections that allow dynamic adjustment of the lifting angle and stroke. The acute angle convergence and pivot mounting enable the arms to adapt their movement range dynamically, increasing the effective lifting stroke and improving transport frame pickup efficiency without adding complex mechanical systems.

AI summary
The invention relates to an inloader, particularly for transporting large-area or large-volume goods. Such inloaders are used especially for transporting flat glass or precast concrete elements, but also pallets and other goods. The inloader comprises two parallel longitudinal vehicle beams (4, 4') to which axle mounting brackets with air-sprung independent wheel suspensions for receiving wheels are attached, and a hydraulic or pneumatic lifting arm (1) movably mounted with bolt receptacles for receiving a fifth wheel plate (6), which carries a pin (7) for connection to a semi-trailer tractor. The necessary ground clearance of such an inloader is generally adjustable via the air springs of the independent wheel suspensions and the hydraulic or pneumatic lifting arm. A disadvantage is that the lifting arm has a considerable weight, which reduces the permissible load capacity of the inloader.The invention is based on the objective of providing an in-loader of the aforementioned type in which the permissible load weight is increased and the force transmission is improved, so that the forces occurring can flow better than with known lifting arms. For this purpose, it is proposed that the lifting arm (1) be formed from two lifting arm arms (5, 5') converging at an acute angle to each other towards the saddle plate (6).
