Self-loading Concrete Mixer

JBC-3.5A Self-loading Concrete Mixer Truck (3.5 m³ Model A, 270° Rotation)

3.5 m³ drum. 270° rotation. Turns where a standard mixer can't.

JBC-3.5A carries a 3.5 m³ mixing drum on a 7830 × 2680 × 4170 mm chassis, and the reaction frame swings 270° on hydraulics — so you can place concrete in an alley or between structures without backing the truck out and re-positioning. Yuchai 4105 turbocharged engine, 85 kW. ZL-280 power-shift gearbox, 4 forward and 4 reverse. It climbs 30° grades and turns inside 5.3 m.

Batch output: 3.5 m³ per batch, 5110 L geometric drum, 18–21 r/min
Engine & parts: Yuchai 4105 turbo, cross-reference parts list available on request
Export files: CE / ISO documents, emission papers by destination country
Supply: quote back within 24h, OEM/ODM from 1 unit, 25–30 day lead time

JBC-3.5A Self-loading Concrete Mixer Truck (3.5 m³ Model A, 270° Rotation)

Batch Output

3.5 m³ per Batch, 5110 L in the Drum

Drum turns at 18–21 r/min. Water tank holds 620 L.

5 m³ per batch at 18–21 r/min — roughly 10–12 batches an hour on a standard load-mix-discharge cycle.

270° hydraulic reaction frame

discharge where the chute reaches, not where the truck can park. No repositioning on tight sites.

Feature

Pour in the Alley, Not from the Street

The reaction frame turns 270° on hydraulics while the truck stays parked.

On a narrow site, the limitation is rarely the drum — it is where the chute can reach. The 270° hydraulic reaction frame lets the operator swing the discharge to the pour point between walls, behind scaffolding or along a slope edge, with the truck on solid ground.

Combined with a 5.3 m minimum turning radius, that means the JBC-3.5A gets in and out of yards a standard mixer truck refuses. The rotation diagram is in the downloadable datasheet.

Feature

Where It Works

Urban infill sites where the truck cannot turn around
Ramps and grades up to 30°
Remote jobs with no nearby batching plant
Rental fleets and contractor purchase programmes
Road, bridge and foundation pours
Private-label assembly for OEM/ODM buyers

Drivetrain

Yuchai 4105 Turbo, ZL-280 Power Shift — Parts List Included

85 kW, 4 forward / 4 reverse, 30 km/h, 30° gradeability.

Engine: Yuchai 4105 turbocharged, rated 85 kW
Transmission: ZL-280 power shift, 4 forward / 4 reverse
Gradeability: 30°
Max speed: 30 km/h

Direction changes under load are handled by the power shift, which matters on repeated back-and-forth pours. Alongside the truck we hand over a parts cross-reference list covering Yuchai engine components, hydraulic parts and common wear items — useful if you already run Yuchai equipment in your fleet.

Questions Buyers Ask Before Ordering

Lead time, parts compatibility, certification and OEM/ODM.

Questions Buyers Ask Before Ordering

Lead time 25–30 days after deposit. One unit per 40HQ container with a loading plan. Parts cross-reference list available. CE/ISO files downloadable. OEM/ODM on colour, decals and configuration from 1 unit.

How long from deposit to shipment, and how does it ship?

25–30 days after deposit for standard configuration. One unit loads into a 40HQ container; we send the loading plan with the proforma invoice. If you need a firm sailing date, give us the destination port and we'll confirm stock and vessel schedule within 24 hours.

Can I get parts for the Yuchai engine and the hydraulic rotation from you?

Yes. The truck runs a Yuchai 4105 turbo and ZL-280 gearbox. Ask for the spare parts compatibility list — it cross-references engine parts, hydraulic components and common wear items so you can check against what your workshop already stocks.

Will the 270° rotation really help on a tight site?

The reaction frame turns 270° on hydraulics, so the chute reaches the pour point while the truck stays put. Pair that with the 5.3 m turning radius and you can work alleys and courtyards where a standard mixer has to reverse out and reposition.

Which certification documents come with the truck?

CE and ISO files are available for download. Emission-standard paperwork is prepared according to your destination country's requirements — tell us the port and we'll confirm which documents apply.

What does OEM/ODM involve and what is the minimum order?

Colour, decals and configuration can be changed. MOQ is 1 unit for standard build; pricing steps down from 3 units. Send your spec sheet and we'll come back with a configuration drawing and price.

How fast can I get a quotation and datasheet?

Within 24 hours. Send the model, any part numbers you want cross-referenced, and your destination port — that lets us quote the truck and the freight in one reply.

What happens if a part fails on site?

Common wear parts sit in regional warehouses. Send the part number and a photo; parts enquiries get an answer within 24 hours, and we'll confirm which warehouse can ship and when.
