> Four Chinese machinery portals in one schema: new-equipment catalogue with specs, CNC machine tools, industrial B2B listings and used construction machinery.

21-sun, jc35, jdzj and lmjx, four Chinese portals with no public API, turned into the same columns: English category, brand, model, price in yuan when published, province, spec sheet and quality flags. To compare prices with Europe, find manufacturers and follow what Chinese brands offer.

QUICK ANSWER

**Quick answer:** Four Chinese machinery portals with no public API (21-sun, jc35, jdzj and lmjx) in one schema: new construction-machinery catalogue with spec sheets, CNC machine tools with suppliers, industrial B2B with tiered prices and used machinery with yuan price, hours and province, with no personal data. Sample of 100 rows in CSV and JSON.

CONTEXT

## Four portals, four formats, one schema

None of the four has an API. Each actor reads the public pages over HTTP, with no browser, and returns the same columns.

| Portal | What it is | What you get | Price | Actor |
|---|---|---|---|---|
| 21-sun.com 铁臂商城 | New construction-machinery catalogue | ~31,000 models: brand, category, photos and full spec sheet | No prices (inquiry only) | [21-sun](https://apify.com/rastriq/21-sun-machinery-catalog-scraper) |
| jc35.com 机床商务网 | B2B for CNC machine tools, lasers and forming | Products, brand, model, supplier, city, technical parameters, origin and MOQ | Reference price or "on request" | [jc35](https://apify.com/rastriq/jc35-machine-tools-scraper) |
| jdzj.com 机电之家 | B2B for industrial and electromechanical equipment | Supply, used and buy requests: tiered price, MOQ, verified supplier, specs | Yuan, with quantity tiers | [jdzj](https://apify.com/rastriq/jdzj-industrial-scraper) |
| lmjx.net 路面机械网 | Used construction and road machinery marketplace | Excavators, loaders, rollers, pavers, cranes: brand, model, hours, province | Yuan (万元 converted); some "面议" | [lmjx](https://apify.com/rastriq/lmjx-used-machinery-scraper) |

One actor per portal, all with the same output schema. The Tiebaobei used marketplace, already on this site, completes the picture of the Chinese market.

**Flag, never drop.** Chinese listings are noisy: one seller's ad covering many models, repair or rental services, token prices. Nothing is filtered: every row carries its warnings in `qualityFlags` (`multi_model_ad`, `service_ad`, `price_on_request`, `stale_listing`…) and you decide what to discard.

**In Chinese and English.** The title is kept in Chinese, as the seller publishes it; the category also arrives in English (`ext_categoryEn`) and the brand often includes its Latin name (`大隈/OKUMA`). Phone numbers, WeChat and QQ are removed from titles and descriptions.

USE CASES

## What Chinese machinery data is used for

Six real use cases: who uses them, what you do and which fields you need.

1 · Used prices in China versus Europe

Machinery traders, exporters and importersCompare the price of a used excavator in China (lmjx) with the European marketplaces on this site to see where there is import or export margin.**Result:** a price table by brand, category and year on both sides.

Fields: `priceCny`, `brand`, `model`, `year`, `hours`, `province`

2 · Supplier sourcing

Industrial procurement and sourcing officesFind manufacturers and distributors of a machine type (machining centres, mining equipment, compressors…) with their city, minimum order and factory price when published.**Result:** a supplier shortlist by category and province.

Fields: `city`, `province`, `moq`, `priceCny`, `ext_categoryEn`

3 · What models Chinese brands sell

Manufacturers, dealers and competitive analystsThe 21-sun catalogue lists the models on sale in China from Sany, XCMG, Komatsu, Caterpillar and dozens more brands, with up to dozens of technical fields per model.**Result:** a range matrix by brand and category, with comparable specs.

Fields: `brand`, `model`, `category`, `specs`

4 · Dealer map

Sales and business development teamsGroup listings by selling company and city to see which dealers move the most volume in each category.**Result:** a ranking of sellers by category and region.

Fields: `seller`, `city`, `province`, `category`

5 · Buyer demand

Manufacturers and exportersjdzj's buy-request board (求购) shows what equipment Chinese industry is looking for, by category and region.**Result:** demand signals to prioritise products or markets.

Fields: `sourceSection`, `title`, `category`, `postedAt`

6 · Market monitor

Analysts and market intelligence teamsSchedule the same categories weekly and compare prices, listing counts and new suppliers. jdzj lets you ask only for what was updated in the last month.**Result:** weekly supply and price series by category.

Fields: `updatedAt`, `priceCny`, `category`, `qualityFlags`

WHAT THE DATA SAYS

## Each portal tells a different part of the story

One short run per portal is enough to see what each one adds.

| Portal | Rows | With price | Distinct brands | Spec fields (max) | Provinces |
|---|---|---|---|---|---|
| 21-sun.com | 40 | 0 | 10 | 67 | — |
| jc35.com | 50 | 5 | 46 | 111 | 12 |
| jdzj.com | 50 | 50 | 9 | 16 | 6 |
| lmjx.net | 40 | 28 | 12 | 0 | — |

Saved-task runs on 21 October 2026 (lmjx: 20 October run in listing mode, without province or spec sheet). "Spec fields" is the number of key-value pairs in the spec sheet of the most complete row.

The 21-sun new catalogue has no prices but spec sheets of up to 67 fields; jc35 is mostly "on request" (45 of 50 products) with spec sheets of up to 111 fields and suppliers in 12 provinces; jdzj publishes a price on every listing in the sample, and lmjx on 28 of 40. That is why they are combined: specs from one side, prices from the other.

Two real rows per portal. The title is shown shortened and in the original Chinese.

**No personal data.** Phone numbers, WeChat, QQ and emails are never collected. This site's samples also leave out the seller name and shop links, because some advertisers are individuals.

## Inputs ready to copy

Paste the input into each actor's JSON tab and press Start. The first four match the saved tasks, as 10-row test runs.

| Task | Input (JSON) | What it is for |
|---|---|---|
| 21-sun · excavators with specs | `{"section": "new_catalog", "categories": ["101001"], "includeDetails": true, "includeFullSpecs": true, "maxItems": 10}` | Excavator range on sale, with specs. |
| jc35 · vertical machining centres | `{"categories": ["4202"], "includeDetails": true, "maxItems": 10}` | Suppliers, brands and technical parameters. |
| jdzj · mining equipment supply | `{"section": "supply", "categories": ["hy6_86"], "includeDetails": true, "maxItems": 10}` | Factory price, minimum order and supplier. |
| lmjx · used earthmoving machinery | `{"categories": ["tufangjixie"], "maxItems": 10}` | Excavators, loaders and more, with price. |
| lmjx · used Komatsu in one province | `{"categories": ["wajueji"], "brand": "komatsu", "province": "guangdong", "includeDetails": true, "maxItems": 10}` | With hours, model and city. |
| jdzj · buy requests from the last month | `{"section": "buy_requests", "updatedWithin": "month", "maxItems": 10}` | What Chinese industry is looking for. |

Each actor charges per result: cheaper in listing mode, a little more with detail pages. From outside China, detail runs are slower.

FAQ

## Frequently asked questions about Chinese machinery data

### Does the data arrive in Chinese?

The title and spec sheet are kept in Chinese, as the portal publishes them. The category also arrives in English in `ext_categoryEn` and many brands include their Latin name. Full translation is done as a custom project.

### Do all portals have prices?

No. 21-sun is an inquiry-only catalogue with no prices; most jc35 products are "on request"; jdzj and lmjx publish a yuan price on a good share of listings. The price type is in `priceType`.

### Why one actor per portal and not a single one?

Because each portal has its own structure, categories and blocking. Kept separate they are easier to maintain and you only pay for the portal you use; the output schema is the same on all four.

### Is personal data included?

Phone numbers, WeChat, QQ and emails are never collected and are removed from titles and descriptions. A company contact name is only added if you turn it on, never for individuals.

### Does it work from outside China?

Yes, over HTTP with no browser. Detail runs are slower from outside China and some portals apply temporary blocks; the actors retry with backoff and you can add your own proxy.

### Can it be compared with European prices?

Yes. This site has the European used-machinery marketplaces and an auction sold-price database; matching them by brand, model and year is a common custom project.
