Welded frame sized to the part or carton it carries
The fixture comes first: once we know the part, the shelf spacing, side guides and stops follow from it.
Industrial Transfer Cart / Warehouse Trolley
Custom Industrial Transfer Carts for Factory and Warehouse
Made-to-order warehouse trolleys and transfer carts for moving parts, cartons and work in progress. Low-platform utility trolleys, shelf carts, rack carts or a purpose-built fixture — typical builds run tube Ø20–50 mm with 1.2–3.0 mm wall, deck plate 0.8–3.0 mm and casters 75–200 mm. We build to your drawing, around the load, the route and the aisle width.

Product Overview
Built Around Load, Movement, Storage and Safety
Doing Metal can customize trolley structure based on your drawings, product photos, sample design, working environment, and quantity target. We review frame strength, caster layout, platform or shelf design, finish, and packing before quotation.
Buyer Problem and Custom Solution
Internal transfer carts usually fail where the fixture meets the frame: shelves that deflect under a full load, dividers that bend, or a cart that cannot be pushed through the narrowest door on the route. Buyers also need the same cart again in six months, which means the drawing has to be repeatable.
Doing Metal Solution
Send a drawing, a photo of the part or a sample cart. We review the load, the part geometry, the fixture layout, tube section, caster rating, finish and packing, then confirm what we would change for manufacturability before quoting. Drawings and jigs are kept on file so a repeat order matches the first one.
Shelf, rack, divider or fixture layout built to the part geometry
Dividers, padded zones and rack arms are welded or bolted depending on whether the cart will ever be reconfigured.
Caster rating and layout matched to route length and floor
Route length, floor joints and elevation changes decide wheel diameter and tread material.
Powder coat, galvanized or stainless finish
Wash-down, outdoor and food-handling routes change both material and finish, so we ask before quoting.
Workshop Photos
What We Actually Build, Photographed in Our Own Workshop
Every photo on this page was taken in our own workshop or at our customer site. No stock images, no renderings.
Transfer cart — the fixture is designed around the part it carries.
Built to drawing — shelf spacing and guides follow one specific part.
Same cart from the side — rack pitch and base clearances set by the part geometry.
Mesh-side platform trolley — welded mesh keeps loose cartons and totes on the deck.
Front view — removable push handle, mesh on all four sides, flat steel deck.
A batch in final inspection before packing — repeat builds hold the same geometry.
Bolt-on casters with welded corner gussets — casters can be swapped in the field.

Engineering Choices
Key Details That Change Trolley Performance and Cost
Foreign material handling buyers often compare the same trolley by load class, wheel system, ergonomic design, towing method, surface finish, and packing. Confirming these details early helps avoid under-built carts and unnecessary cost.
Frame and Deck
Tube size, plate thickness, reinforcement ribs, weld layout, and deck surface should match the real load, cargo footprint, and impact during use.
Caster Layout
Two fixed plus two swivel wheels, four swivel wheels, brake casters, pneumatic tires, or larger PU wheels can be selected for different routes and floor conditions.
Push, Pull or Tow
Manual push handles, double handles, tow bars, coupling arms, forklift handling, or AGV interface requirements can be reviewed for custom projects.
Safety and Parking
Brake position, side rails, mesh guards, anti-slip decks, wheel locks, and load distribution help make the trolley safer during loading and parking.
Finish Durability
Powder coating, galvanizing, stainless steel, or custom color should be selected based on indoor/outdoor use, corrosion exposure, and brand requirements.
Export Packing
Assembled, semi-assembled, knock-down, carton, pallet, and spare wheel packing options affect freight volume, assembly time, and after-sales support.
Quality Checks
Inspection Points for This Trolley Type
Quality checks are adjusted according to the actual trolley type, structure, load, and application.
Fixture fit against the real part
Shelf deflection under full load
Weld inspection at load points
Caster rolling and brake holding test
Frame squareness and diagonal check
Finish and packing protection inspection
Angle and squareness checked against a template on every welded frame.
Joint-by-joint angle checks happen during assembly, not only at final inspection.
Same gauge, same angles — that is how unit 500 matches unit 1.

FAQ
Common Questions Before Ordering Custom Trolleys
What makes a warehouse trolley suitable for picking?
The shelf height, usable shelf depth, handle position, caster layout and turning clearance should match the cartons, bins and route used by the operator. A picking cart is designed around the sequence of work, not only its outside dimensions.
Can you make a heavy duty warehouse trolley for narrow aisles?
Yes. Share the narrowest aisle, turning space, largest carton, target load and floor condition. We can then review the frame width, handle projection, shelf arrangement and caster layout before quotation.
What information is needed for an internal material handling cart?
Please send cargo dimensions and weight, route distance, floor joints or thresholds, working frequency, parking condition, shelf or bin layout, quantity and packing target.
Can you customize the size?
Yes. Overall size, platform size, shelf layout, cage size, handle height, and wheel configuration can be customized based on your use case.
Can I send a photo instead of a drawing?
Yes. Photos, samples, sketches, and use requirements can start the review. Drawings are recommended for accurate quotation and production.
Which wheel should I choose?
Wheel choice depends on load, floor type, noise requirement, movement distance, brake needs, and whether the trolley is pushed, pulled, or parked on slopes.
Can the trolley be foldable?
Foldable handles, foldable cages, removable shelves, and knock-down packing can be discussed when storage space or freight volume is important.
Do you support OEM branding?
Custom color, logo plate, label, carton artwork, and distributor packing can be reviewed for OEM and private-label trolley programs.
Can it work with towing equipment?
For heavy loads or long routes, please confirm tow bar, coupling arm, forklift, tugger cart, or AGV interface requirements during the RFQ stage.
What is the MOQ?
Our standard MOQ is 50 units for most custom trolley programs. For large-size or heavy-duty projects, quantities from 10 units may be discussed after reviewing the structure, material, casters, finish and packing. Samples and first articles are handled separately.
Can you quote from a PDF, DWG, DXF or STEP file?
Yes. Those formats are accepted for review, and reference photos or samples are useful when the drawing does not show the working environment.
How is lead time confirmed?
Lead time is confirmed after the drawing revision, material, quantity, finish, wheel model and packing method are agreed. We avoid giving a generic date that does not fit the project.
Can you provide supplier approval documents?
Tell us which documents your purchasing team needs. Material, inspection, packing and project records can be discussed, while certifications are published only after internal verification.
How will the trolley be packed?
We can review assembled, semi-assembled or knock-down packing, including cartons, pallets, hardware bags, labels and finish protection according to the shipping plan.
Can I request a sample or first article?
Yes. Sample or first-article review can be discussed according to the drawing maturity, project quantity, tooling and approval process.
