Two sizes. One standard.
Choose 12.7 m³ for standard batch sizes or 14.7 m³ to maximise payload per trip. Both share the same proven chassis, running gear, and PMP motor system.
12.7 m³
The standard capacity variant. Suited for regular batch plant operations and urban ready-mix delivery routes where weight limits are a priority consideration.
14.7 m³
Maximum payload capacity for high-volume construction projects. Fewer trips per day means lower fuel cost and higher site productivity.
12.7 m³ — Dimensional side elevation
14.7 m³ — Dimensional side elevation
Key Features
Every component chosen for durability, performance, and ease of operation on the job site.
Drum & Mixing System
The Drum. The Heart of the Operation.
High-volume drum manufactured from abrasion-resistant steel, driven by a PMP hydraulic motor for reliable mixing and discharge in all conditions.
PMP Hydraulic Motor
Bi-directional rotation: forward at 2–6 rpm for mixing, reverse at up to 12–14 rpm for fast, clean discharge on site.
Abrasion-Resistant Construction
Drum shell and mixing blades manufactured from abrasion-resistant steel — engineered to withstand the constant wear of concrete aggregate.
Chassis & Structural Engineering
Built for the Long Haul.
S355J2+N structural steel chassis designed to handle the extreme cyclical loads of a fully laden concrete mixer in daily operation.
Axle Configuration
3-axle semi-trailer layout distributes the weight of a full drum across multiple axles, keeping individual axle loads within European regulatory limits.
Industrial Coating System
High-quality industrial coating applied over blast-prepared steel. Drum and chassis finish in customer-specified RAL colour for fleet branding.
Hydraulics & Drive System
Precision Hydraulic Drive.
PMP hydraulic motor delivers reliable, consistent drum rotation — from batch plant to job site, every cycle.
2–6 RPM Mixing Rotation
Forward rotation at 2–6 rpm keeps concrete homogeneous throughout transit, preventing segregation of aggregate and cement.
Up to 14 RPM Discharge
Reverse rotation up to 12–14 rpm enables rapid, complete discharge on site — minimising pour time and turnaround cycle.
Surface Protection & Finish
Industrial Coating
Applied over SA 2.5 blast-prepared steel for maximum adhesion and long-term protection against concrete residue and weather.
Custom Colour Options
Fleet branding made easy. Specify any RAL colour for drum and chassis to match your company livery.
Full LED Lighting
Complete LED lighting suite — rear combination lamps, side markers, licence plate illumination — compliant with European road regulations.
Tyres & Running Gear
Commercial Tyres
Heavy-duty commercial tyres rated for the axle load of a fully laden concrete mixer, selected to comply with European road regulations and provide stability throughout the delivery cycle.
PMP Hydraulic Motor Unit
Industry-standard PMP motor unit — trusted by concrete mixer manufacturers globally for its reliability, serviceability, and consistent output across high daily cycle counts.

Material & Engineering FAQs
What drum capacities are available on the STU Mixer Trailer?
STU TRAILERS® offers two standard drum capacities: 12.7 m³ and 14.7 m³. Both variants use the same chassis and running gear, with the drum size being the primary differentiator. Custom capacities can be discussed based on project requirements.
Technical Details:12.7 m³ is suited for standard ready-mix batches; 14.7 m³ maximises payload per trip, reducing fuel costs on high-volume projects.
What hydraulic motor drives the drum?
The drum is driven by a PMP brand hydraulic motor, renowned for its reliability in concrete mixing applications. The motor powers both the mixing rotation during transit and the discharge direction on site.
Technical Details:PMP motors provide bi-directional rotation: forward for mixing at 2–6 rpm and reverse for discharge at up to 12–14 rpm.
What steel is used for the drum construction?
The drum shell and blades are manufactured from high-strength, abrasion-resistant steel to withstand the highly abrasive nature of concrete. The exterior chassis uses S355J2+N structural steel.
Technical Details:Abrasion-resistant steel grades such as Hardox 400 or equivalent are commonly used for drum liners and mixing blades to extend service life.
What surface protection does the mixer trailer use?
The chassis and structural components receive a high-quality industrial coating system. The drum exterior is finished with a durable paint system resistant to concrete residue, UV exposure, and weather. Customers can specify RAL colours.
Technical Details:Surface preparation to SA 2.5 blast standard before primer and topcoat application ensures long-term adhesion.
How many axles does the mixer trailer have?
The standard configuration is a 3-axle semi-trailer, providing excellent load distribution for the heavy gross vehicle weight of a fully loaded concrete mixer. Axle specifications comply with European transport regulations.
Technical Details:3-axle configuration typically allows up to 27,000 kg total trailer axle load under European regulations, depending on axle spacing.
What lighting system is installed?
The trailer is equipped with a complete LED lighting system compliant with European road regulations. This includes rear combination lamps, side marker lamps, and licence plate illumination for safe road operation.
Technical Details:LED lighting reduces power draw compared to conventional bulbs and provides longer service life in the harsh vibration environment of concrete mixers.
Can the mixer trailer be customised?
Yes. STU TRAILERS® offers customisation of drum capacity, drum colour (any RAL), chassis configuration, axle choice, and additional equipment. We work directly with customers to deliver a trailer tailored to their fleet requirements.
Technical Details:Custom orders typically require 8–16 weeks lead time depending on specification complexity and current production schedule.
What markets does STU supply mixer trailers to?
STU TRAILERS® supplies mixer trailers across Europe and beyond, with demonstrated deployments in Ireland and other European markets. We serve ready-mix concrete producers, construction companies, and transport operators.
Technical Details:Trailers are configured to comply with the road transport regulations of the destination country, including lighting standards and axle load limits.
