Concrete Mixer Truck

A concrete mixer truck combines a road-vehicle chassis with a rotating mixing drum for concrete transport and discharge. The equipment must be selected around the concrete supply method, delivery route, receiving area and the limits of the configured vehicle.

The EPDAS schedule covers eight CMT models in two tables. Their listed maximum mixing volumes are 3, 4, 5, 6, 8, 9, 10 and 12 m³. Geometric tank-volume entries are larger and must not be advertised as the same thing.

Although the source heading refers to 8–12 m³, it also contains the CMT3–CMT6 table. Both groups are retained so the full documented range remains available for comparison.

CMT3–CMT6

CMT3, CMT4, CMT5 and CMT6 list 3–6 m³ maximum mixing volumes with left-hand-drive 4 × 2 chassis entries. Dimensions and engine-power figures vary between model columns.

CMT8–CMT12

CMT8, CMT9, CMT10 and CMT12 list 8–12 m³ maximum mixing volumes and left-hand-drive 6 × 4 chassis entries. A selection of chassis names in a table does not confirm that every listed make is available for every order.

The two complete original matrices retain geometric tank volume, maximum mixing volume, feeding/unloading entries and chassis details. Source-stated performance and engine labels require confirmation for the configured truck and operating conditions.

Maximum mixing volume is distinct from geometric tank volume and permitted road payload. Source performance, chassis, emission and component entries require confirmation for the actual configured vehicle and destination.

Mixing Drum

The tank-volume row describes geometric space in the drum. The maximum mixing-volume row is a separate concrete-capacity entry. For example, CMT12 lists a 19.6 m³ tank and 12 m³ maximum mixing volume; these values must remain distinct.

Hydraulic Mixing Drive

Pump, motor and reducer entries identify the drum-drive package by group and model. Confirm the actual components, documentation and support scope rather than assuming that all trucks share one package.

Road-Vehicle Chassis

Chassis, wheelbase, brakes, steering and engine entries affect vehicle fit. The assembled truck needs to be evaluated as a complete configuration rather than treating the drum as its legal payload rating.

Concrete or its specified ingredients enter the drum through the receiving arrangement. Drum operation maintains the required mixing or agitation function for the agreed supply method, followed by discharge at the receiving point.

The actual production method matters. A truck receiving already-mixed concrete and a truck completing a specified mixing process are different operating arrangements; the source does not provide a verified procedure for every method.

Loading, drum speed, travel and discharge must follow the actual equipment instructions and the concrete producer’s requirements. This page is not an operating or concrete acceptance procedure.

A 12 m³ maximum mixing-volume entry is not proof that 12 m³ of any concrete may legally be carried on every road. Concrete density, vehicle mass, axle loads and destination requirements must be checked for the actual truck.

The table does not provide a complete axle-load or legal-payload approval. Confirm the chassis and finished vehicle documentation before using a mixing-volume figure in transport planning.

The delivery operation needs an agreed concrete specification, loading records and receiving arrangements. Travel delays and a restricted unloading area can affect the supply schedule even when the drum has sufficient nominal capacity.

Water-tank capacity does not establish permission to add that quantity to the concrete. Any water adjustment must remain within the producer’s approved mix and quality process, with the required record and acceptance checks.

Concrete Delivery Fleets

Mixer trucks can be assessed for concrete delivery between a production point and a construction site. Compare batch sizes, access, queueing space and the required arrival pattern together.

Supplying a Concrete Pump

If concrete is discharged into a pump, coordinate the receiving geometry and the supply rate with that pump. A truck’s feeding or unloading entry cannot alone establish the completed placement rate.

Review the full vehicle length, width, height and wheelbase for the selected model. The larger CMT group has different dimensions and axle arrangements from the smaller group, so a route suitable for one cannot automatically be used for another.

Confirm access beneath overhead restrictions, turning approaches and the discharge position. Tank dimensions alone cannot establish vehicle clearance or the space needed to serve a hopper or receiving chute.

The smaller group lists a 150 L water tank and the larger group 450 L. These are system-storage entries and should be matched to the actual cleaning and supply arrangement, not treated as batch-water prescriptions.

The source describes Euro-IV engines in the smaller group and Euro-VI in the larger group. These labels require verification for the actual engine and destination; they do not establish registration or approval for every market.

The vehicle and mixing body have related but distinct servicing requirements. The drum drive, hydraulics, water system and wear components need their applicable maintenance instructions in addition to chassis servicing.

Discuss manuals, inspection records, commissioning, spare parts and support arrangements with EPDAS. Confirm responsibility for both the selected chassis and body; warranty and service response are not fixed by the general table.

A useful comparison includes the configured vehicle, legal carrying capability, delivery cycle, servicing and the receiving operation. A larger drum may not improve productivity where site access or unloading space is the limiting factor.

The source’s feeding, unloading and residue figures are stated under unspecified conditions. Obtain the relevant performance basis before calculating fleet size, a fixed cost per delivery or a promised cycle time.
