Tow tongue and coupling designed for your tugger or forklift
The hitch is the highest-stressed part of the cart. Tell us the tugger model, pin type or the coupling drawing and the design follows it.
Tow Train Cart / Tugger Cart
Tow Train Carts Built for Warehouse Routes
Carts designed to be pulled in a train behind a tugger or forklift rather than pushed by hand. Towing changes everything about the frame: the tow tongue takes the whole pull load, the coupling has to suit the tug you already own, the caster layout has to track instead of wander, and braking has to cover the whole train rather than one cart. Send the tug specification, train length, route and floor, and we engineer from there.

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
Tow train programmes fail in predictable places: tongues that bend because the pull load was never calculated, couplings that do not match the tug, carts that snake behind the tugger because the caster layout was copied from a hand-pushed cart, and trains that cannot be stopped safely on a slope. None of these show up when the cart is specified as if it were pushed.
Doing Metal Solution
Send the tugger or towing method, coupling type or pin dimensions, number of carts per train, load per cart, route including slopes and turning radius, floor condition and quantity. We review tongue length and section, hitch reinforcement, caster layout for tracking, and the braking provision, then quote from a drawing with the coupling interface dimensioned.
Caster layout that tracks behind the tug instead of wandering
Tracking behaviour decides whether the train snakes down the aisle: caster type, fixed and swivel mix and the tongue length are reviewed together.
Frame and hitch points engineered for pull load, not push load
Pull loads are applied low and horizontally, which is a completely different load case from a handle push - the frame is reinforced accordingly.
Braking and parking provision for the whole train
A train of loaded carts needs a braking plan, not only brakes on each cart, and that plan depends on slope and stopping distance.
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.
Front view - hitch points and tow tongue are engineered from the tug specification.
Loaded and moving - transfer carts take the same pull loads on internal routes.
Load path - pull loads travel differently from push loads, so the frame is reinforced where it matters.
Fleet built to one drawing - every cart in the train behaves the same.
Route reality - the load and the floor decide the wheel specification.
Shipped ready to run - hitches fitted or bagged, as you prefer.

Buyer Decision Guide
Details That Decide Whether This Trolley Will Work in Daily Use
Use this section before sending an RFQ. It translates the search term into the practical design points our team needs to review.
| Decision Area | What to Confirm | Why It Matters |
|---|---|---|
| Tug interface | Tugger model, pin or coupler drawing, tow height | Everything else follows from this - without it the hitch is guesswork |
| Train length | How many carts per train and total train weight | Decides tongue strength, braking plan and aisle turning radius |
| Route | Slopes, surface, turning radius, pedestrian crossings | Decides braking provision and how much tracking control is needed |
| Load per cart | Weight and how it sits on the deck | Decides frame section and caster rating for each position in the train |
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.
Hitch and tongue weld inspection
Coupling fit check against the stated tug interface
Tracking observation while towed
Brake holding test on the specified slope
Frame deflection check under rated pull load
Finish, marking and packing 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 do you need to know about our tugger?
The tugger model, the coupling or pin type and its dimensions, and the towing height. Send a photo of the current hitch if you do not have a drawing, and we will work from that.
Will the carts track straight behind the tug?
Tracking depends on caster type, the fixed and swivel mix, and tongue length. Give us the route and train length and we will specify the layout that reduces snaking rather than copying a hand-pushed cart specification.
How is a train of loaded carts braked?
Braking has to cover the whole train, not one cart. Tell us the slopes on the route and the stopping distance you need, and we will propose the brake provision per cart and for the train as a whole.
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.
