Remote Hydraulic Welder Cart for Fence-Line Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding setups for metal fabrication, particularly in the construction industry, face challenges in efficiently and conveniently moving and positioning portable welding machines on-site, especially for long metal fence installations, as they require frequent manual relocation and handling, which is time-consuming and labor-intensive.
Innovation Solution
A self-contained, remotely drivable and steerable wheeled cart powered by a hydraulic pump motor, driven by an electric motor powered by an internal combustion engine, equipped with a radio remote controller for mobility and steering, allowing the cart to be moved independently along a fence line without manual intervention, and featuring storage for welding equipment and supplies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual relocation and handling of portable welding machines is used, then the setup is simple and requires no additional power systems, but it is time-consuming and labor-intensive
Solution Approach 1:
The welding machine is mounted on a self-propelled cart with drive wheels and steering mechanism, enabling the equipment to move itself to different work locations without manual relocation. The cart autonomously navigates to positions where welding is needed, eliminating the need for workers to manually handle and relocate the welding machine.
Solution Approach 2:
The cart provides dynamic mobility through powered drive wheels and steerable front wheels, allowing the welding machine to be dynamically repositioned along the fence line. This dynamic positioning capability enables the welding machine to reach various work areas efficiently without manual intervention.
2Reliability
If the welding machine is secured to a truck or trailer, then it provides stable power supply, but frequent movement requires loading and unloading which reduces productivity
Solution Approach 1:
The system is segmented into a mobile cart platform and a welding machine, separating the mobility function from the welding function. The cart handles all movement and positioning, while the welding machine remains stationary on the cart, eliminating the need to load and unload the heavy welding equipment when moving to different work locations.
Solution Approach 2:
The cart acts as an intermediary between the welding machine and the work locations. It provides the mobility and navigation capabilities, allowing the welding machine to be transported to various positions along the fence line without requiring repeated loading and unloading from a truck or trailer.
3Adaptability or versatility
If the welding machine is moved in increments along the fence line, then it can reach different work areas, but frequent repositioning stops welding progress and reduces efficiency
Solution Approach 1:
The cart autonomously moves the welding machine to different work areas along the fence line without requiring workers to manually reposition the equipment. The self-propelled mechanism eliminates the time and labor needed for manual handling during repositioning operations.
Solution Approach 2:
The cart provides continuous dynamic movement capability along the fence line, allowing smooth transitions between work areas. The powered drive system enables the cart to efficiently navigate to new positions without interrupting the welding workflow or requiring manual intervention.

Function Achieved in This Case
Enables efficient and convenient on-site welding by allowing the cart to be remotely controlled to new locations along a fence line, reducing the need for frequent vehicle movement and manual handling, thus enhancing productivity and safety while accommodating rough terrain and varying work site conditions.
Implementation Method 1
an internal combustion engine, the engine being powered, for example, by petroleum liquid fuel stored in a tank on the cart
Implementation Method 2
electricity, which electricity is generated on the cart, for example, by an internal combustion engine
Implementation Method 3
driven, for example, at any wheel or set of wheels or tracks by, for example, a hydraulic pump motor

AI summary
A self-contained track or wheeled welders' cart may be driven at a wheel or set of wheels and/or at a track or set of tracks by hydraulic wheel drive motor(s). The hydraulic wheel/track motor(s) may in turn be driven by high-pressure hydraulic oil provided by an electric-hydraulic pump motor driven by electricity that is generated on the cart by an internal combustion engine. The powered cart may be moved forward and backward via, for example, a radio or other non-wired-signal remote controller in communication with a drive system for the cart's electric-hydraulic driven tracks(s) and/or wheels(s) on the cart. Also, the remote controller may be in communication with a rack and pinion type steering mechanism, for example. Electricity created on the cart may be used also for a portable welding system carried on the cart.
