Running a concrete agitator or ready-mix truck means the electrics have to keep up — drum and cab controls, radio remotes, wiring looms, lighting and cameras that take a hard day’s work. BMC Auto Electrical looks after agitator and cement truck auto electrical work from our workshop in Warana, and with mobile service for heavy vehicles across the Sunshine Coast.
We install, fault-find and repair Woodtech agitator control systems, including the Promix SD Standard Transit Mixer Radio Remote Control System, plus the broader truck electrics that keep your mixer reliable on site and on the road.
Call 07 5208 9307 to book workshop or mobile heavy-vehicle support.

If a control system or remote is playing up, or you’re upgrading gear on an agitator, tell us the symptoms and the truck — we’ll diagnose properly rather than guessing at parts.

BMC Auto Electrical installs, fault-finds and repairs Woodtech Promix SD systems and related agitator electrics for Sunshine Coast operators — cabin units, handheld remotes, wiring and the circuits that tie drum, chute and engine controls together.
We are auto electricians who work on heavy vehicles and plant. We do not claim to be an official Woodtech dealer or distributor. If your job needs specific Woodtech parts or software support, we’ll tell you what’s involved and source or coordinate what’s required for a proper repair or install.

Yes. We install, fault-find and repair Woodtech Promix SD radio remote control systems for transit mixers / agitators, including cabin units, handheld remotes and related wiring. We’re auto electricians — not an official Woodtech dealer — and we’ll be clear about parts and scope before work starts.
Typical Promix SD controls cover plant mix, discharge / mix, chute up / down, engine speed (engine up / down), cabin / remote modes, plus halt / resume and stop on the handheld remote. Exact layout can vary by truck and install — bring the truck or remote in and we’ll check it.
Often yes. Intermittent drum, chute or remote faults can be wiring, connectors, switches, the cabin unit, the handheld remote or the wider control system. We diagnose from the symptoms and the truck, then repair or replace what’s needed.
Yes. We repair and rewire looms and related circuits for agitator and cement trucks when damage, age or upgrades require it.
