JBC-3.5A 自上料搅拌车（3.5方A款 270°旋转）

3.5m³ drum, 270° swing frame, 85kW Yuchai. Measured 30° climb, 5.3m turns.

The JBC-3.5A self-loading concrete mixer truck runs a Yuchai 4105 turbocharged engine at 85 kW through a ZL-280 power shift gearbox (4 forward, 4 reverse). The 3.5 m³ drum sits on a 270° hydraulically rotated reverse frame, so the chute reaches the pour point in alleys and courtyards where a rear-discharge truck has to reverse out and reset. Tested 30° gradeability and a 5,300 mm turning radius. Overall 7,830×2,680×4,170 mm, wheelbase 2,900 mm, curb weight 7,800 kg. Drum geometric capacity 5,110 L, drum speed 18–21 r/min. Fuel tank 120 L, hydraulic oil 120 L, water tank 620 L. Common wear parts are listed with a model matching table; CE/EPA documents ship with the unit.

Where the 270° swing earns its keep
Feature

Where the 270° swing earns its keep

Alley renovations, rural roads, private builds

On an alley renovation the truck pulls in, swings the chute to the pour point and backs out once — instead of three or four resets. On rural road and irrigation work the 3.5 m³ drum keeps output up while the 30° climb handles the embankments. Contractors rotating between small sites get one machine that fits all of them, with a parts list that travels with it.

What you get over a standard self-loading mixer

Points worth checking on any competing quote

OUR OFFER

This Product

  • 270° swing vs. a 180° frame — a wider discharge arc means fewer truck moves per pour on tight sites.
  • 85 kW Yuchai vs. lower-output engines — holds torque on the 30° climb and keeps cycle times short.
  • Lead time in the contract — 30 days standard, 20 days expedited, penalty clause on overrun.
  • Parts list with matching table — confirm fitment before you buy, cut downtime later.
  • Factory direct, tiered pricing — 1–2, 3–5, 6+ units; no agent markup.

Ask any supplier for the discharge range diagram, the gradeability test video and the penalty clause. We send all three with the quote.

Generic Market Alternatives

  • Unknown material source & batch inconsistency
  • No compatibility verification for your machine model
  • Lead times stretch 3-8 weeks with no clear status updates
  • Weak or non-existent post-sales engineering support
Procurement Questions

Answers before you send the PO

MOQ, site fit, certifications, parts, shipping

What is the MOQ, and how is the lead time guaranteed?
MOQ is 1 unit. Standard lead time is 30 days after deposit; 20 days expedited with a surcharge. The date goes into the contract with a penalty clause if we run late — ask for the clause text with your quote.
Can the truck be adapted to my site — drum size, swing angle, engine, color?
Yes. Standard is 3.5 m³ drum and 270° swing; other swing angles, engine configuration, and paint color can be quoted. Send your site dimensions (lane width, gate height, pour points) and we respond with a proposal within 24 hours.
Which certifications and export documents come with the truck?
CE and EPA certificates are standard. The document pack includes commercial invoice, packing list, certificate of origin, and fumigation certificate where required. Tell us the destination port and we confirm what your customs broker needs.
How do I check spare parts compatibility before ordering?
We supply a compatible parts list with a model matching table. Send the part number or the component name (e.g., drum roller, hydraulic pump, chute liner) and we confirm fitment and stock status; common wear parts dispatch in 48 hours from overseas warehouses.
RoRo or container — which shipping method should I choose?
Assembled units ship RoRo; disassembled units fit in a container and reduce freight cost. Shipping dimensions are 7830×2680×4170 mm. We provide a packing plan and loading arrangement so you can compare total landed cost before booking.
How does the 270° swing actually help on a narrow site?
The chute reaches across a wide arc while the truck stays put — no reversing out of an alley to re-approach the pour. Ask for the discharge range diagram; overlay it on your site plan to check coverage before you buy.
What does after-sales support look like in practice?
Response within 24 hours; technical support by video call. We walk your mechanic through diagnosis with the parts list in hand, and confirm part numbers the same session where possible.
