4.0 m³ per batch. Drum and cab turn 270° together. Yuchai 4108 turbo, 91 kW.
The JBC-4.0B is a 4.0 m³ self-loading concrete mixer built for jobs where the ready-mix truck cannot reach or cannot wait. The drum and cab rotate together through 270° on hydraulics, so you load, mix and discharge without repositioning the machine.
We ship from stock in 15–25 days, take 1-unit orders, and send a compatible parts list for JBC series machines before you commit.

Rural builds, road repair, precast yards, rental fleets
The JBC-4.0B pays for itself where delivery is slow or impossible: mountain villages, road shoulder repairs, precast yards changing batch sizes through the day, and rental fleets that need a compact 4 m³ unit. The 120 L fuel tank and 750 L water tank cover a working shift without constant refilling, and the 270° rotation lets you pour at an angle instead of driving around the form.

Compatible parts list for JBC series, custom paint from 2 units
If you already run JBC mixers, ask for the compatible parts list before you order — drum blades, seals, hoses and swivel joints are matched to the series, so you are not stuck with one supplier for wear items. For fleet buyers, custom paint and logo start at 2 units, with a 30–40 day build. One unit is enough to trial the machine on your own sites.
