Custom Handling Carts
Fully custom-engineered T-slot aluminum handling carts built around your exact part geometry, process interface, load requirement, and facility constraint — not adapted from a standard catalog platform. When your application does not fit a standard cart, we engineer it from the ground up. Designed and manufactured in Auburn Hills, MI.
Why Choose Modular Solutions for Custom Handling Carts?
Standard carts are compromises. A custom-engineered cart or dolly is designed to eliminate part damage, process inefficiency, and ergonomic risk at the source — not worked around after the fact.
Engineered to Your Part Geometry
Part-specific nest fixtures, position stops, foam-lined contact cradles, and custom surface configurations ensure the part is supported, located, and protected at every point in the transport route — not placed on a flat surface and hoped to stay put.
Process Interface Precision
Custom carts are designed to dock, present, or transfer parts at the exact height, angle, and position required by the downstream process — eliminating ergonomic lifts, realignment steps, and process cycle time lost to cart-to-process misalignment.
Load-Rated to Your Actual Weight
Frame profile, crossmember spacing, caster specification, and fastener design are all sized to the actual load — from 100 lb light-duty assemblies to 5,000 lb structural weldments requiring heavy-duty dolly frames.
AGV, AGC & Tugger Train Compatible
Custom carts can be designed to AGV coupling geometry, precision tow hitch specifications for tugger trains, and fleet-standardized dimensions for automated material handling systems — engineered to the coupling spec of your specific system.
Fleet Production to a Single Standard
Custom cart programs are not one-offs — we produce fleets of identical units to the same approved drawings with consistent dimensions, coupling geometry, and load capacity across every cart in the fleet, with the design retained for future replenishment.
T-Slot Reconfigurability Built In
Even ground-up custom carts are built in T-slot aluminum, meaning fixture positions, shelf heights, accessory mounts, and handle locations can be adjusted with hex tools as the process evolves — without scrapping the cart and starting over.
Key Features & Benefits
Engineering details that make a custom cart perform as a precision material handling tool rather than a generic transport platform.
Part-Specific Nest Fixtures
Machined or formed nest fixtures, foam-lined cradles, and T-slot-adjustable position stops locate parts precisely on the cart and prevent movement during transport, handling, and docking operations. Fixture geometry is designed from your part drawing or 3D model.
Precision Coupling & Docking Geometry
Locating pins, kinematic coupling pads, and hard stop surfaces engineered to process interface dimensions allow the cart to dock to a machine, fixture, or station repeatably within the positional tolerance required by the process — no manual alignment required at the interface.
Custom Caster & Mobility Configuration
Swivel-and-fixed caster arrangements, heavy-duty rigid casters for straight-line towing, tri-caster configurations for tight turning radius, and pneumatic or polyurethane wheel options are all available — matched to your floor surface, load, and route geometry.
Structural Frame Sizing to Load
45 Series, 90 Series, and heavy structural T-slot profiles are selected based on actual load calculations. Frame crossmember spacing, gusset placement, and base frame design are all calculated for the actual weight, load distribution, and dynamic handling forces.
Integrated Handling Features
Ergonomic push handles, pull bars, tow hitch provisions, lifting eyes, forklift pocket provisions, and restraint strap anchor points can all be integrated into the custom cart design — handling provisions designed in from the start rather than bolted on as afterthoughts.
Engineering Drawing Package
Every custom cart is delivered with a full engineering drawing package — dimensioned fabrication drawings, BOM, and assembly instructions — so the design is documented for fleet expansion, revision, and future production runs without redesign from scratch.
Custom Handling Cart Applications
Custom handling carts from Modular Solutions are deployed across automotive, aerospace, heavy equipment, medical device, and general manufacturing operations.

Frequently Asked Questions
Common questions about custom handling cart programs from Modular Solutions.
What makes a custom cart different from a standard cart with added accessories?
A custom cart is engineered ground-up from your part geometry, process interface, load rating, route constraints, and operator ergonomics — not adapted from a standard platform. The result is a cart where every dimension, mount point, surface height, and mobility feature is optimized for the specific application. Standard carts with accessories are compromises; custom carts are solutions. When part damage, process inefficiency, or ergonomic risk exists with a standard cart, a custom-engineered design eliminates those issues at the source.
How do I start a custom handling cart development program?
The process begins with an application review where you describe the part, process, transport route, load, and interface requirements. We assess requirements, propose an engineering approach, and produce a concept design for review before committing to fabrication drawings. For complex multi-cart programs, a formal engineering kickoff with your manufacturing, logistics, and safety teams ensures all requirements are captured before design begins.
Can custom handling carts be designed for AGV or tugger train use?
Yes. Custom carts can be designed with AGV coupling geometry, precision tow hitch provisions for tugger trains, fleet-standardized dimensions for automated systems, and bumper rail configurations for train coupling. For AGV applications, we design to the coupling specification provided by the AGV supplier. For tugger train fleets, cart-to-cart coupling geometry and aisle clearance dimensions are designed as part of the fleet specification.
What is the typical lead time for a custom handling cart?
Lead time depends on design complexity and quantity. Straightforward custom carts typically run 3–5 weeks from approved drawings to delivery. Complex multi-interface designs with special fixtures, safety provisions, or fleet quantities run 5–8 weeks. Engineering review and drawing approval time is in addition to fabrication lead time. We provide a project schedule with milestones at the start of each custom program.
Can you build a fleet of identical custom carts for a production line?
Yes. Fleet production is a common custom cart application — standardized carts produced to the same design for a production line, tugger train, or AGC system. Fleet carts are built from the same approved drawings with consistent dimensions, coupling geometry, and load capacity across every unit. For ongoing replenishment, we retain the design on file so additional units can be produced to the same specification as the original fleet.
