Deck engineered around real load spread, not only total kilograms
A 1000 kg load sitting on four points needs a different frame than a 1000 kg load spread evenly across the deck. Send the footprint and contact points, or a photo of how it is loaded.
Heavy Duty Platform Truck / Heavy Flatbed Cart
Heavy Duty Platform Truck Manufacturer
Made-to-order heavy platform trucks for loads that ordinary carts should never carry: dies, molds, motor housings, steel coil sections, machine sub-assemblies and palletised goods. In the United States search results, this product is a heavy duty platform truck or heavy flatbed cart; in the UK and Australia it is a heavy duty platform trolley. We do not keep a catalogue of fixed models — the frame, deck, reinforcement and caster layout are engineered from the load you actually carry, the route it travels and the floor it travels on.

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
Buyers searching for a heavy duty platform truck usually have one of three problems: a standard cart that bent in service, a route that no standard cart fits, or a load whose contact points concentrate weight into a small area. Increasing the stated capacity alone rarely fixes any of them — the frame has to distribute the load into the casters, and the wheels have to survive the actual floor.
Doing Metal Solution
Send the target load, load footprint or contact points, deck size, deck height if it matters, the route including narrowest door and worst floor condition, wheel and brake preference, finish and quantity. We review the frame tube, deck plate, reinforcement layout, caster rating and packing method together, then quote from a drawing you can approve. Typical heavy builds use tube sections well above light-duty carts, with thicker caster plates and larger wheels than the buyer expects.
Welded frame with load-carrying cross members down to the caster plates
On heavy builds most failures start at the caster plate or the cross member above it, so both are reviewed together with the weld sequence before quoting.
Wheel diameter and tread chosen for concrete, epoxy, steel plate or yard
Wheel diameter is the cheapest way to reduce pushing effort: bigger wheels roll over joints, plate gaps and debris that stop a small wheel.
Tow bar, coupling arm or forklift-facing details available on request
If the truck will ever be towed, pulled by a tugger or moved by forklift, say so during RFQ — it changes the frame, the tow tongue and the safety details.
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.
Full view — the proportions are set by the load footprint, not by a standard size.
Deck and base together — this is where load spreads down into the casters.
Load path — cross members carry load to the caster plates, not to the deck skin.
Wheels — diameter, tread and bearing decide whether one operator can move the load.
Load rating is tested, not printed — tell us the number you need and we engineer to it.
Export loading — heavy trucks are blocked, strapped and photographed before the doors close.

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 |
|---|---|---|
| Load | Total load plus footprint and contact points | A concentrated load needs more reinforcement directly above the casters than a spread load of the same weight |
| Route | Narrowest door, turning space, ramps, plate gaps | These decide frame width, handle projection and minimum wheel diameter |
| Floor | Concrete, epoxy, steel plate, gravel or mixed | Floor condition decides tread material and whether larger wheels pay for themselves |
| Handling | Manual push, towed, or moved by forklift | Towing and forklift handling add tow tongues, pockets and different safety details |
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.
Frame squareness and diagonal measurement
Deck deflection check under rated load
Weld inspection at caster plates and cross members
Wheel rolling resistance and brake holding on a slope
Handle stiffness at pushing height
Coating thickness and finish condition before packing
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 load can a heavy duty platform truck actually carry?
Capacity is engineered from your load and its contact points rather than taken from a catalogue. Send total load, footprint or contact points, route and floor condition, and we review frame section, deck thickness, reinforcement, caster plates and wheel rating together before quoting.
Which wheels suit heavy loads on rough floors?
Large diameter wheels roll over joints, plate gaps and debris more easily than small ones. Cast iron or high-grade polyurethane handles high loads on good floors; pneumatic or elastic rubber suits yards and broken surfaces. Tell us the floor and we recommend the tread.
Can the truck be towed or moved by forklift?
Yes. Tow tongues, coupling arms, AGV interfaces or forklift pockets can be designed in, but they change the frame and safety details, so they must be confirmed before the drawing is finalised.
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.
