Zebang Two-Wheel Trailer Underframe
Zebang's two-wheel trailer catalogue shows underframes with two main wheels, a drawbar and a hand-cranked jack with caster. One photograph shows a rectangular frame with crossmembers; another shows a central-spine frame with a jointed drawbar. Zebang publishes no model number, dimensions or payload for these trailers. For a farm-site job, send the body you want to mount, your towing vehicle and the cargo, and ask Zebang for a drawing and full load and brake specification of the build it offers.

Build my procurement briefTwo underframe layouts in the photographs
Zebang calls both entries a “two-wheel trailer”. The photographs show two different frames, and neither page gives a code or a rating to tell them apart.
| What the photograph shows | What to ask Zebang |
|---|---|
| Rectangular frame with crossmembers | Several crossmembers and an A-shaped drawbar area. Ask for the body-support and fastening drawing with dimensions, since the photo has no scale. |
| Central spine with jointed drawbar | A single central member and visible joints in the drawbar. Ask what the joints are for, how they lock and how far they move. |
| Two main wheels and jack caster | Both photos show a support caster with a hand crank. Ask for its support rating and handling limits. |
| No cargo body | Neither photo shows a deck, hopper, tailgate or unloading system. List the complete assembly you need as its own line item. |
Mounting a body on the frame
The rectangular frame looks ready for a body, but the photo gives no fixing points, steel thickness or support loads. Send Zebang a drawing of the body you plan to fit, how the cargo is spread and how you load and unload it. Ask for a design that shows how those loads travel into the frame, axle and tow connection.
On a farm, a loose-crop bin, a pallet deck and a fixed equipment platform each load the frame differently. These are examples for your enquiry; Zebang does not list them as options. Ask Zebang to name the body and mounting it will supply, and weld only to points shown on its fabrication drawing.

Tow eye, pin and drawbar as one connection
The photographs show eye-style tow ends without dimensions. The central-spine frame also has a different drawbar from the rectangular one, so settle the connection step by step.
Your towing vehicle
Name the tow machine and its coupling: dimensions, height and the arrangement its maker permits. Check pin or ball size against the eye drawing.
The trailer drawbar
Ask for the eye and pin drawing, the connection hardware and the allowed articulation, and for the locked and moving positions of any joints.
Clearance in use
Check the body, drawbar and wheels through the turns and slopes you expect, using Zebang's approved layout and a demonstration.
Parts on the order
Put the confirmed coupling and drawbar part numbers and the full build drawing on the offer and the acceptance record.
Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| Product name | Two-wheel trailer family; no model code supplied [1] [2] [3] | Two official pages share the same Chinese product name. Ask Zebang for a build reference to put on your order. |
| Frame shown (second page) | Rectangular underframe with crossmembers [2] [5] | Ask for frame dimensions and steel grades. |
| Frame shown (first page) | Central-spine layout with jointed drawbar [1] [4] | A different layout. Ask what the drawbar joint does and how it locks. |
| Wheels and support | Two main wheels and hand-cranked jack/caster [4] [5] | Ask for tyre, bearing and jack ratings. |
| Tow end | Eye-style openings visible in the illustrations [4] [5] | Ask for eye and pin dimensions, articulation range and coupling approval. |
| Body | No cargo body shown in the selected image [5] | Specify the deck, hopper or bin you need as a separate item. |
| Catalogue date | Published September 2022 [1] [2] | Ask Zebang for the current build and stock position. |
| Load, dimensions and speed | Not published on the catalogue pages [1] [2] | Request a specification for the complete build you order. |
Ask for a full rating package
The catalogue pages give no payload, unladen mass, axle rating or operating speed. Wheel size and crossmember count in a photo cannot stand in for them. Keep cargo mass separate from the finished trailer's mass, and ask how Zebang defines the rated configuration.
For the build you choose, get the frame, axle, hub and tyre ratings, the coupling and drawbar limits and the load distribution in one package. The trailer's payload is set by its weakest part. The jack and caster need their own rated capacity and instructions. Ask Zebang in writing for the safe load, speed and any loading or ballast limits.
Buyer questions
Do these trailers have model numbers?
The catalogue pages use a general product name with no model number. Ask Zebang for a build reference on your quote. [1] [2]
Does the photo show a complete cargo body?
No. It shows the underframe, main wheels, drawbar and jack. Order the body you need as a separate item. [5]
Is the jointed drawbar for tipping?
Zebang does not explain the joint on the page. Ask what it does and how it locks. [4]
Brakes and road use
Zebang lists overrun-brake and air-brake products in their own catalogue categories. The two-wheel photographs show no brake control diagram or actuation method, and no stopping test. Ask which braking and parking equipment comes on your trailer and check it against your towing vehicle.
If the trailer will go on public roads, request its operating limits, documents and any approval needed where you work. Zebang's workplace inspection reports deal with worker exposure in the workshop; axle load, braking and road eligibility need product documents.
Wheel, hub and jack parts
Zebang sells parts by category. For these trailers, ask for the tyre, hub and bearing specifications that go with your build. Hubs, jacks and similar running gear are grouped in our parts and attachments section.
| Part of the trailer | Record to request |
|---|---|
| Main wheels and hubs | Tyre size and load rating, wheel bolt pattern, hub, bearing and seal part numbers, and approved replacements. Ask whether the tyre suits off-road work. |
| Jack and caster | Part number, support capacity, fixing method, and operating and storage instructions. |
| Frame and joints | Body-mounting and drawbar-joint drawings, fastener and locking part numbers, and inspection points. |
| Complete kit | Packing and parts list and current lead time. The 2022 catalogue photo shows the family; ask whether the build is in stock. |
Checking the delivered underframe
Because the family has no model number, the agreed drawings and parts list become the order identity. Our guide to sourcing farm machine components to drawing explains how first-article checks tie a delivery back to those drawings. Inspect against them.
Drawing and dimensions
Measure overall, wheel, body-mount and coupling dimensions against the approved drawing.
Parts and documents
Check hubs, tyres, tow connection, jack and any brakes against the agreed parts list and rating package.
Complete assembly
Check the body mounting and the towing and braking functions with Zebang's written procedure for that build, and record what you find.
Handover
Collect the operating limits, assembly and maintenance instructions and the parts support terms for the trailer.
