Custom Mobility Cart & WIP Cart for Equipment Support
Does your equipment need a support platform built around its dimensions and mounting requirements? Plymouth Industries designed and fabricated a custom mobility cart for a defense technology company, combining a welded carbon steel frame with application-specific mounting features.
The project illustrates an important principle behind custom work in progress (WIP) carts: start with the equipment and the workflow. Frame dimensions, attachment points, handling access, and floor support should work together to fit the application.
A Custom Steel Cart Built Around the Equipment
A standard utility cart may offer the right footprint but lack the mounting locations or frame configuration needed for specialized equipment. This custom mobility cart was fabricated to project-specific print requirements. Its open construction provides access around the frame, while diagonal bracing reinforces the structure. Integrated fork pockets provide a handling interface at the base, and four swivel mount feet support the unit when positioned.
For equipment support and work-in-process applications, these details matter. The platform needs to accommodate both the equipment attached to it and the way the assembly will be handled.
Application-Specific Mounting Features
This custom steel cart includes features that go beyond a general-purpose shelf or flat platform:
- 18 threaded mounting points: The specified 3/8-16 rivet nuts provide attachment locations for equipment or application-specific components.
- Machined pockets: These features accommodate the requirements defined in the project drawings.
- Four swivel mount feet: Floor-contact supports allow the frame to rest on feet when positioned.
- Braced carbon steel construction: Welded framing and diagonal members form the equipment support structure.
- Integrated fork pockets: Base openings provide access for fork handling.
Together, these features create a platform configured for the customer’s equipment, reducing the need to work around the limitations of a stock cart.
What This Project Shows About Custom WIP Carts
Work in progress carts, also called work in process carts, support parts and assemblies between production stages. Their value comes from matching the load, access requirements, and handling method to the operation.
This custom mobility cart demonstrates several considerations that also guide custom WIP cart design:
- Fit the equipment. Establish the footprint, support locations, and mounting interfaces before fabrication.
- Plan for access. Account for installation, fastening, inspection, and other work around the assembly.
- Define the handling method. Specify how the platform will move and how it will be supported when stationary.
Different workflows call for different configurations. A caster-equipped assembly cart, a line-side staging cart, and a fork-handled equipment platform each serve a distinct purpose. Plymouth Industries develops custom WIP carts around those operational requirements.
Custom Cart Design and Fabrication in Wisconsin
Plymouth Industries manufactures custom carts and racks in Plymouth, Wisconsin. Our fabrication capabilities bring steel construction, machining, welding, finishing, and assembly together to support application-specific projects.
For your next material handling cart, start with the details that determine fit and function: equipment dimensions, total load, mounting requirements, available floor space, and handling method. Drawings, photos, or a 3D model can help communicate those needs and establish a practical starting point.
