Movable Gate in Work Implement Load Rest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pallet fork frames obstruct easy access to and from the operator's cab, making it difficult for operators to enter and exit, while also failing to adequately secure loads and protect the operator from falling materials.
Innovation Solution
A work implement frame with a movable gate in the load rest, allowing easier access by pivoting or sliding, which is biased to close automatically, providing secure load support and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional pallet fork frame with a solid load rest is used, then load security and operator protection are improved, but operator access to the cab becomes difficult
Solution Approach 1:
The load rest is segmented by introducing a removable or movable gate component that can be separated from the main load rest structure. This allows the gate to be removed or opened for operator access while the remaining load rest structure continues to provide load support and protection.
Solution Approach 2:
The gate is designed to be movable rather than fixed, allowing it to transition between different positions (open/closed, removed/attached). This dynamic component enables the load rest to adapt between providing full protection and allowing operator access as needed.
2Object-affected harmful factors
If the frame is positioned to protect the operator from falling materials, then operator safety is improved, but access to the cab is obstructed
Solution Approach 1:
The protective structure is segmented by separating the gate from the main load rest, allowing the gate to be removed or opened to create an access path through the frame while the remaining structure maintains protection against falling materials.
Solution Approach 2:
The gate component is extracted as a separate, removable element from the load rest structure. This allows the gate to be taken out or opened for access while the main load rest structure remains in place to provide protection from falling materials.
3Strength
If a solid load rest extends across the entire width of the frame, then load support and protection are improved, but operator access becomes difficult
Solution Approach 1:
The load rest is divided into a main structural portion that provides load support and a separate gate portion that can be removed or opened. This segmentation allows the main structure to maintain full width for load support while the gate portion can be opened to allow operator access.
Solution Approach 2:
The gate portion of the load rest is designed to be movable or removable, allowing the load rest to dynamically adjust between a complete structure for maximum load support and an open configuration for operator access.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances operator safety and convenience by facilitating easy entry and exit while securing loads and preventing material from falling onto the cab.
Implementation Method 1
The gate is biased in its closed position so it closes after the operator releases it and enters the cab

AI summary
A work implement frame having a top support and a bottom support. The top support and bottom support are tied together structurally by end plates and/or vertical ribs. One or more fork tines may be combined with the top or bottom support of the frame and are adapted to carry pallets or other loads as is know in the art. The frame includes a load rest to help support the load. The load rest is typically positioned near the top of the frame. A gate in the load rest is movable between an open position and a closed position. In its open position an operator may pass through the gate to enter the cab. The gate may be pivotally or slidably combined with the load rest.
