YUYAN 388 backhoe loader: configuration, engine and key points for quotation

What the YUYAN 388 is: read the main specifications first

Product page uses the name YUYAN 388. The series includes 388, 388T and 388H, and some documents name this machine 388T. Do not judge engine, undercarriage or working equipment by the suffix alone: ask the supplier to use an exact, consistent designation in quotation, spec sheet and contract, and to state which configuration each parameter belongs to; if document names differ, request an explanation and written confirmation before ordering.

Confirm trench depth, truck bed height and loading space with the site supervisor before filtering by parameters. The 2026 catalog lists front lift capacity 2,500 kg, discharge height 2,807 mm, discharge distance 908 mm, front bucket breakout force 47 kN; rear swing angle 180°, rear bucket digging force 50 kN and dipper digging force 31 kN. Those figures are not a single capability achievable in every posture; for lifting or special work request the applicable operating documentation.

For a rental fleet, have operators evaluate the usual job depths and attachment needs; as a dealer, first define a fixed configuration to offer. Published maximum figures establish an inquiry range and do not promise production on any soil, shift or project. Do not treat operating weight as transport weight, and do not use overall machine height as packing dimensions after disassembly.

Why get a configuration-based written quote

YUYAN 388 does not publish a fixed price; request price by configuration and rely on the written quotation. State engine and emissions version, transmission and axle options, hydraulic requirements (fixed or variable flow), mechanical or pilot controls, cab and attachments, quantity and destination port in your inquiry. Availability of options and their parameters must be confirmed item by item; do not treat photos or the model name alone as a complete configuration list.

• Engine: specify brand, full model, power and emissions version together; confirm documents and delivery time.
• Transmission, axles and hydraulic control: confirm transmission and axle options separately, the hydraulic requirements (fixed or variable flow) and whether controls are mechanical or pilot; do not combine them as a single configuration.
• Work equipment and cab: list telescopic or non‑telescopic boom, included buckets, hydraulic lines, cab layout and additional requirements.
• Quantity, destination port and OEM/ODM: state the quantity to order, the destination port, color, marking and decals; request that total price and unit price correspond to the same itemized list.

When you compare the price of a new Chinese backhoe loader, fill in the missing fields in each offer before comparing amounts. Seeing the same 388 and air conditioning does not prove the engine emission version, transmission, and rear boom are the same. Do not price one option first while assuming the rest is identical; ask suppliers to list the base configuration, options, included loose parts, and exclusions separately.

ImportantAn FOB quote is not the total cost to destination. Check international freight, insurance, local taxes, port and customs fees and inland transport separately with your customs broker and logistics providers; the quotation should clearly state the FOB loading port, scope of responsibilities and price validity period.

Project budgets should separate the machine price from import costs, but don’t compare only the per-unit amount between two suppliers. If one includes the engine and specific spare parts you require and another lists only generic names, ask both to reissue offers based on the same requirements. When requesting a quote, provide the destination port so the supplier can help prepare relevant shipping documentation; do not interpret the machine quotation as a commitment on ocean freight or local permitting fees.

Engine: keep the exact model name and verify the certificate

The 2026 catalog lists the standard engine as Cummins 4BTA3.9-C110-II, Stage II, rated power 82 kW / 110 HP, rated speed 2,200 rpm; among upgraded options is Cummins Stage II, 86 kW (AA), whose full model must be confirmed when you request a quote. The table below only compiles information verifiable in the catalog. When choosing, first confirm which certificates and site requirements are accepted in the destination country and then evaluate the service network; do not rely solely on brand name or power to determine importability.

Standard and upgrade engines listed in the 2026 catalog must not have their power ratings mixed; availability of other engines or emissions versions must be consulted separately. Stage and Euro are different marking systems and are not directly equivalent. Quotations must include the engine family, full model, a nameplate or certificate sample, the basis for the power measurement, the applicable emissions regulation and the certificate issuer.

Also request fuel and maintenance requirements for the selected engine, filter model numbers, diagnostic method, and — if fitted with an emissions aftertreatment system — its service documentation. With that information, your local workshop can assess parts availability and service conditions. Photographs are for observing the layout; engine identity and emissions version are confirmed by the delivered machine’s nameplate and written documents.

Choose emissions by destination, not just by the label

Below are the main points of the official rules consulted up to 2026-11-03, relating to a construction backhoe loader of about 82 kW, without applying road truck standards. Definitions of power in different regulations should be verified against the certificate. First have the customs broker or competent authority in the destination country confirm the tariff classification, estimated import date and required certificates; then provide that confirmation to YUYAN so we can assist in matching the engine and documentation.

Providing only a promotional sheet that says Stage is not sufficient. Chile requires verification of the engine type‑or‑family emissions certificate before import; the standard engine name Stage II does not replace that procedure. Colombia uses independent non‑road limit tables and requires obtaining the CEPD; Euro VI requirements for road vehicles do not apply directly to the backhoe loader and cannot be inferred from example labels as if they were the minimum required.

Mexico’s new standard comes into force close to this publication date; orders scheduled for later import should be specially reviewed. There are sales transition arrangements for new engines already imported or manufactured before the effective date, which do not constitute an automatic exemption for new orders. Colombia’s year‑end amendment addresses scope and certification procedures and should not be read as a blanket increase of emissions limits.

ImportantYUYAN can help provide the selected engine’s documentation and match configurations, but does not guarantee emissions approval, customs clearance or local registration. If local requirements are not confirmed, do not lock in a lower‑emission version solely to reduce purchase cost; the competent authority performs the final review.

Transmission, hydraulics and cab: which items you must specify

The 2026 catalog lists standard domestic transmission and drive axles; the spec table shows YJ290 single‑stage three‑element torque converter, fixed‑shaft power‑shift transmission, 4 forward / 4 reverse. Confirm separately the selected transmission and axle brand and model and their corresponding parameters. Transmission choice is not the same as hydraulic control choice; the quotation should list the control type for the front and rear work attachments separately.

• Axles and tires: the catalog lists Feicheng axles; front tires 14-17.5 and rear 19.5L-24. Drive arrangement and optional axles must be confirmed separately; request that the supply list and photos correspond to the same chassis unit.
• Hydraulic system: the catalog standard is fixed‑displacement hydraulics with pilot control; pumps Chuankong／Quancheng, valves Haorun／Huasheng and cylinders Jinli are listed; steering is Danfoss／Zhenjiang. Steering pressure is shown as 14 MPa. Main hydraulic working pressure must be requested separately; do not infer it from the tire specification cell.
• Front and rear working equipment: the catalog lists front bucket float, and upgrade options include a 4-in-1 bucket, a six-in-one bucket, and a telescopic arm. Please verify separately the flow, interfaces, hoses/lines, and control requirements for your chosen attachment; catalog images are not a list of included attachments.
• Stabilizers and structure: Ask the supplier to confirm the stabilizer layout, rear working device and structural materials, and to provide photos of the delivered configuration; do not reuse configuration descriptions from older versions.

The 2026 catalog lists a Rongshida cab, heating and air conditioning, 360° panoramic camera, and a Huacheng instrument panel. Seat, work lights, windows and the specific control layout must be verified against the delivered configuration. If your project requires ROPS protection certification, an operator manual in a specific language, or inspection documents, list those as separate requirements and request supporting documentation; a catalog description does not equal obtaining the safety certifications required by the destination country.

OEM/ODM: color, logo, decals, cab layout and engine configuration negotiable. As a dealer, attach logo files and color requirements and request approval of the final artwork. Exterior customization does not replace the identification of the manufacturer, machine and engine. If you change the cab layout or controls, request an updated spec sheet and operating instructions rather than receiving documents for the original standard version.

Separate standard items, chosen options and unselected options. If the order uses mechanical controls, a lever seen in a photo does not confirm full equipment; if using pilot control, confirm how the loader and rear excavating are operated. For rental machines, have operators review the control layout and instructions first, then have procurement confirm the final list.

Write the full configuration into the quotation and contract, not just '388'

A written quotation must link the machine identity, technical configuration and commercial terms. Listing only “388 new,” imported axles, air conditioning and an amount can omit engine model, emissions data or a non-extendable boom. Replace any phrase like standard, on request or same as photo with a verifiable, specific description. If a new machine has not yet been assigned serial numbers, state when they will be provided and include them in the delivery documentation.

Agree who inspects, what is inspected, and how discrepancies are resolved; test videos must be traceable to the actual delivered machine and its identification. Warranty should specify start conditions, covered components, exclusions and required claim documents; do not assume a fixed duration here. Also list spare parts by model and quantity: a single kit of common parts does not by itself constitute a long-term parts-supply commitment.

If you have read our 366T class backhoe procurement guide, its checklist—verifying the serial number or QR code of a genuine new Cummins engine, buffered cylinders, new (not reconditioned) axles, box-section boom and frame, verifiable warranty service records and high-intensity factory test video for the delivered unit—can serve as a reference for further questions. When requesting a quote for the 388, you may ask for the same evidence corresponding to the chosen configuration.

Before signing, attach the final engine and work-implement table and confirm there is no conflict between the contract text and the attachment. If component substitutions are permitted, require the buyer’s written approval and a re-check of emissions documentation. For dealer orders, keep each unit’s configuration consistent with the paperwork; do not finalize color artwork while leaving the engine version blank.

Send configuration and destination port to receive a written quotation

1. Step 1: write the job requirements. Provide main materials, trench depth, loading requirements, attachments, site space, altitude and temperature, and state whether the machine will be for owner-use, rental, or distribution.
2. Step 2: state destination and engine status. Provide destination country, destination port and expected import date, plus locally confirmed emissions and document requirements; mark any unconfirmed items as pending verification.
3. Step 3: write configuration and quantities. Specify engine and emissions, transmission and axles, hydraulics and controls, boom/arm and attachments, cab, OEM/ODM, quantity, spare parts and acceptance documents; ask the supplier to respond in writing to each item with a quotation.

This site also lists the YUYAN 366T; in the 2026 catalog its operating weight is 7,200 kg. Pricing is per configuration and must be confirmed in writing. If you are considering this class, read the 366T-class backhoe loader purchase checklist on this site, and ask that both quotations use the same intended use, engine and emissions requirements, hydraulics and controls, and destination port terms; do not assume the configuration is the same as the 388 just by weight or model.

If you plan to load 2 units into one 40HQ container, obtain separately the final disassembly, packing, repacking and lashing plan that matches the configuration. This is only a quotation reminder; it does not confirm that this loading quantity applies to every configuration. Do not infer a fixed freight rate, fixed packing time, or treat catalog dimensions as the post-disassembly packing dimensions.

You may send the checklist above and your destination port to YUYAN to request a written quotation for the exact model and configuration. Ask that pending engine certificates, delivery times or options be listed separately rather than omitted. That lets you verify import conditions first, then compare machine and commercial terms. YUYAN can assist preparing documents; final price and delivery are subject to the parties’ written confirmation.
