Self-loading Concrete Mixer

JBC-3.5B Self-loading Concrete Mixer (3.5 m³ B Variant, 270° Rotation)

3.5 m³ per batch. 270° hydraulic discharge. Yuchai 85kW. Rated for 30° grades.

The JBC-3.5B is the B variant of the 3.5 m³ self-loading concrete mixer. The reaction frame rotates 270° on hydraulics, and the drum tilts forward to discharge across a 290° fan pattern, so the operator can pour without moving the machine. Power comes from a Yuchai 4105 turbocharged engine rated 85 kW, matched to a ZL-280 power-shift transmission with 4 forward and 4 reverse gears; maximum gradeability is 30°. Overall size is 7730×2700×4180 mm, wheelbase 2650 mm, curb weight 7900 kg, minimum turning radius 5300 mm.

Tank and drum figures for site planning: drum geometric capacity 5110 L, drum speed 18-21 r/min, concrete output 3.5 m³ per batch. Fuel tank 120 L, hydraulic system 120 L, water tank 620 L. The cab is the deluxe version with a vacuum air-cushion shock-absorbing seat, heating and cooling air conditioning, a driving camera, and tank-chain wiring harness. We can send the Yuchai 85kW engine and hydraulic rotation spare parts list, a 40HQ container loading plan (2 units), CE/EPA/Euro emission certificates where applicable, and current lead time. Trial orders from 1 unit; OEM color, logo and attachments on request.

Road, Tunnel, Rural and High-Rise Pours
Feature

Road, Tunnel, Rural and High-Rise Pours

Matched to the sites where repositioning costs time

The JBC-3.5B shows up on road construction and maintenance, tunnel and underground works, rural and remote supply runs, high-rise pouring, hilly terrain projects, and precast yards. The 270° rotation and 30° gradeability are the two figures that decide whether it fits your site — if your access road is steeper than 30° or your pour face is wider than one drum position, tell us and we will say plainly whether this model is the right one.

FAQ

Questions Buyers Ask Before Ordering

Lead time, MOQ, Yuchai parts, container loading and certificates

How long from order to shipment for the JBC-3.5B?
30 days after order confirmation is the standard. If you have a vessel cut-off, send the date and we will confirm whether current stock or a production slot can meet it before you place the deposit.
Can I order just one unit to test, and how does pricing step down?
Yes — 1 unit is accepted as a trial order. Wholesale price tiers start at 2 units and step again at 4 and 6 units. Send the quantity you are planning and we will return the price bracket with the datasheet.
Do you have the spare parts list for the Yuchai 4105 85kW engine?
We supply a full parts list covering filters, belts, injectors and the hydraulic rotation components, with model cross-reference. Tell us your engine serial number and we match it before shipping.
How many JBC-3.5B units fit in a 40HQ?
Two units per 40HQ after disassembly. The loading plan uses the 7730×2700×4180 mm envelope and 7900 kg curb weight; we send the drawing with the quotation so your freight forwarder can confirm.
Which emission certificate applies to my country?
CE, EPA and Euro documentation are available depending on destination. Send the port and country and we confirm which certificate is issued with the machine — the paperwork is fixed before production, not after.
What does the warranty cover and how fast is support?
12 months on major components. Remote diagnosis responds within 48 hours; some regions have local parts stock — ask for your area before ordering. Consumables and wear parts are listed separately in the parts list.
Can the color, logo or discharge chute be changed?
Yes. OEM covers paint color, decals and logo, plus attachments such as an extra water tank or a different discharge chute. Send the spec and we confirm the added lead time, usually a few days on top of 30.
