Engineering Concrete,
On Wheels
HaulMix is a technology and engineering-driven equipment company building fully automatic, weight-based mobile concrete mixers that deliver RMC-plant precision anywhere, anytime.
Technologies used at Haulmix
At HaulMix, technology isn’t an add-on—it’s the core philosophy. We design mobile concrete production systems that combine precision batching, robust hydraulics, and intelligent controls to produce consistent, specification-grade concrete on site.
Our approach is simple: bring the accuracy and repeatability of a stationary RMC plant into a truck-mounted platform, while eliminating the need for permanent infrastructure, external power, and material wastage. Every HaulMix mixer is engineered to batch solid ingredients by weight, dose liquids precisely, mix in a high-torque PAN mixer, and discharge only after the batch meets defined parameters.
Engineering & Product Development
HaulMix equipment emerges from a disciplined product development cycle: concept validation → system architecture → subsystem prototyping → integration → field trials → iterative refinement.
System-level integration
Hydraulics, electronics, and mechanical structures are co-designed to work as a single, reliable system on wheels.
Modular architecture
Compartments for aggregates, cement/fly ash/GGBS, water, and admixtures are engineered for quick changeovers and scalable capacities (6–12 m³ transport).
Safety-first design
24 VDC control architecture and interlocked sequences reduce electrical risk and prevent out-of-sequence operations.
Maintainability
Service points, quick couplers, and accessible components minimize downtime in real-world site conditions.
PLC Automation & Controls
HaulMix uses industrial-grade PLC (Programmable Logic Controller) automation as the “central nervous system” of each mixer. The PLC executes the complete production cycle: recipe selection, weighing, dosing, mixing sequence & discharge control.
Recipe-driven batching
Operators select a mix design; the PLC enforces proportions and sequence without manual guesswork.
Real-time monitoring
Sensors feed data to the PLC, which adjusts actuators and valves to maintain target parameters.
Data & traceability
Production logs and batch reports support quality assurance and accountability.
Human-intervention-free operation
Interlocks and automated sequences reduce operator error and variability.
Electronic Load-Cell Technology
Precision starts with measurement. HaulMix integrates multiple electronic load cells to weigh solid ingredients directly at the point of batching, similar to conventional RMC plants.
Weight-based accuracy
Aggregates and binders are measured by weight, not volume, ensuring correct proportions batch after batch.
Consistency
Electronic load cells provide stable, repeatable readings under mobile conditions.
Quality compliance
Accurate ingredient measurement supports compliance with mix-design specifications and strength targets.
In HaulMix systems, load cells work in tandem with the PLC to close the loop between “target weight” and “actual weight,” enabling tight control over every batch.
Hydraulic Technology
HaulMix’s patented hydraulic drive system is the muscle behind its mobility and precision. Instead of relying on external power or complex mechanical linkages, critical functions—feeding, mixing, water/admixture dosing, and discharge—are powered by a purpose-built hydraulic circuit.
Patented hydraulic circuit
Designed for high flow, high torque, and fast cycle times while maintaining control and safety.
Integrated power unit
A dedicated slave engine runs only during production, switching off during transit to save fuel and reduce wear.
Responsive actuation
Hydraulic motors and valves enable rapid, synchronized operations for water discharge, admixture dosing, and mixer control.
This architecture allows HaulMix to deliver plant-like performance on a mobile chassis without compromising reliability.
Mixing Technology
At the heart of every HaulMix mixer is a high-speed, high-torque PAN mixer—an industry-proven design for homogeneous concrete in short cycle times.
Intensive mixing action
PAN mixers create strong shear and turbulence, ensuring uniform distribution of cement, aggregates, water, and admixtures.
Controlled discharge
The discharge gate opens only after the batch completes the required mixing time, protecting consistency and strength.
Batch-wise discipline
Each batch is a controlled event with defined start, mix, and discharge—unlike continuous volumetric systems.
The result is a highly homogeneous mix that meets structural and workability requirements, even in demanding site environments.
Water Management Technology
Water control is critical for workability and strength. HaulMix incorporates dedicated water tanks, high-flow pumps, and hydraulically operated valves to dose water precisely and rapidly.
Segregated, swivel-able tanks
Interconnected water tanks with patented design support balanced weight distribution and flexible site operations.
Fast, accurate dosing
High-flow pumps and large-diameter discharge lines reduce cycle time while maintaining dosage accuracy.
W/C ratio discipline
Precise water measurement supports target water–cement ratios, directly influencing strength and durability.
By treating water as a measured ingredient—not an estimate—HaulMix improves batch-to-batch consistency.
Pollution Control Technology
Environmental performance is a core differentiator for HaulMix. The system is designed to minimize material wastage, wash-water runoff, and uncontrolled discharge—common sources of pollution in traditional concrete operations.
On-board, PLC-operated pollution control
Automated sequences and interlocks prevent uncontrolled material release and support cleaner operations.
Zero/low-wastage batching
Weight-based batching and closed sequences reduce spillage and leftover material.
Urban-friendly operation
By producing concrete on demand at or near the point of use, HaulMix reduces wash-water discharge in city areas and the environmental footprint of long-distance wet transport.
This aligns HaulMix with modern sustainability expectations for construction equipment.

Testing & Quality
HaulMix equipment undergoes rigorous validation to ensure it performs reliably under real-world conditions.
Subsystem validation
Hydraulics, load cells, PLC I/O, and mixing mechanisms are tested individually before integration.
System-level trials
Full production cycles are run to verify batching accuracy, mixing homogeneity, and discharge behavior.
Field feedback loops
Operational data and user feedback inform iterative improvements in hardware and control logic.
The goal is simple: every HaulMix unit should deliver repeatable, specification-grade concrete with minimal downtime.
