Tractor Hoist Bracket Support System for Mast Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Farmers and construction workers face challenges in moving larger and bulky items using tractors, often requiring additional equipment like forklifts, which can be inconvenient and space-consuming.
Innovation Solution
A bracket support system for tractor hoists, comprising an upper mast bracket, lower brackets, a stiffener bracket, and a support shaft, that connects the hoist to the tractor, allowing it to lift items while preventing damage to the mounting mast and facilitating movement with a hydraulic cylinder, and also connects trailers to tractors through pivoting mast brackets, enabling efficient use of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a tractor is used to move larger and bulky items, then the tractor's torque capability is utilized, but the tractor cannot effectively lift or move very heavy items without additional equipment
Solution Approach 1:
The patent combines the lifting function into the tractor by mounting a hoist system directly onto the tractor frame. The hoist assembly integrates with the tractor's existing structure, merging two separate functions (traction and lifting) into a single vehicle system, thereby expanding the tractor's versatility without requiring a separate forklift
2Weight of moving object
If additional equipment like a forklift is added to the tractor, then the lifting capability is improved, but the space required for equipment increases
Solution Approach 1:
The hoist system is integrated directly onto the tractor frame, merging the lifting function into the existing vehicle structure. This eliminates the need for a separate forklift attachment and reduces the overall equipment space required, as the lifting mechanism shares the tractor's chassis and support structure
Solution Approach 2:
The tractor is designed to perform multiple functions - both ground transportation and vertical lifting - through the integrated hoist system. This multi-functionality allows a single piece of equipment to replace what would traditionally require two separate machines (tractor and forklift), thereby conserving space
3Ease of operation
If the mounting mast is used to support the hoist, then the hoist can be connected to the tractor, but the mounting mast may bend or be damaged during lifting operations
Solution Approach 1:
The patent applies localized reinforcement to the mounting mast structure. Stiffener brackets are positioned at specific critical locations along the mast where bending moments are highest during lifting operations. These brackets provide localized structural support without requiring reinforcement of the entire mast length, thereby maintaining structural integrity while preserving the ease of connection
4Weight of moving object
If the hoist is connected to the tractor, then lifting capability is enabled, but the system complexity increases with multiple brackets and support structures
Solution Approach 1:
The support system is divided into discrete, modular components - upper mast brackets, lower brackets, stiffener brackets, and support shafts - that can be independently installed and adjusted. This segmentation allows for easier assembly, maintenance, and adaptation while distributing the structural load across multiple specialized components rather than requiring a single complex structure
