1. Background: The Need for Mobility in Concrete Production

In today’s construction industry, speed, efficiency, and flexibility have become decisive factors in ensuring project progress and cost optimization.
In many projects — especially infrastructure, residential, industrial, or transportation works — construction often takes place across multiple locations, under tight deadlines, and with varying production demands at each stage.

Traditionally, contractors have relied on stationary concrete batching plants, which provide stable performance but have significant limitations when relocation is required.
Dismantling, transporting, and reinstalling the plant consumes considerable time and cost, and may also affect equipment integrity.

For this reason, the Mobi concrete batching plant has emerged as a new trend in recent years — a plant that can be relocated without dismantling any components.
It is considered an ideal solution for mobile contractors, offering maximum flexibility in on-site concrete supply for all types of construction projects.

2. Introduction to the Mobi Concrete Batching Plant

The Mobi plant is specially designed with a mobile steel frame, allowing the entire system to be transported as a single unit from one site to another.
Unlike stationary plants that must be disassembled, Mobi can be moved simply by disconnecting the power supply and towing it with a truck or specialized trailer.

Recommended configuration:

• Plant capacity: 30 – 75 m³/h

• Aggregate bins: 2 – 3 bins

• Cement silos: 1 – 2 silos

With this capacity range, the Mobi plant is well-suited for small to medium-scale projects or short-term on-site concrete supply, significantly reducing the cost of transporting ready-mix concrete from distant plants.

In Vietnam, HTEN (Hoang Thinh Engineering JSC) is among the pioneers in designing, manufacturing, and supplying Mobi concrete batching plants, meeting international technical standards and adapting to local construction conditions.

3. Key Advantages of the Mobi Concrete Batching Plant

3.1. High Mobility – No Dismantling Required

The standout feature of the Mobi plant is its ability to move the entire system without disassembly.
All components — including aggregate bins, conveyors, mixer, and control cabinet — are mounted on a high-strength steel chassis, ensuring stability and safety during transportation.

Relocation only requires:

• Disconnecting electrical, water, and piping systems

• Lifting the plant onto a flatbed trailer using a crane

• Transporting it to the new site and securing the supports

• Placing it on a flat 30 cm thick concrete foundation

Total relocation time is typically 1 day, compared to several days for stationary plants — allowing contractors full flexibility in site planning and project scheduling.

3.2. Stable Mixing Performance – Flexible Configuration

Despite its compact and mobile design, the Mobi plant delivers high mixing efficiency and uniform concrete quality.
Its twin-shaft compulsory mixer ensures fast and thorough mixing, producing concrete with excellent workability and compressive strength.

Optional configurations include:

• 2–3 aggregate bins for different sand and stone types

• 1–2 cement silos (30–60 tons each)

• Cement screw conveyor for continuous feeding

• Electronic weighing system with PLC automatic control for precise dosing

• Water and additive dosing system for accurate ratio control

This ensures that the Mobi plant fully complies with the required technical standards for on-site concrete production.

3.3. Fast Installation – Ready to Operate in 3–5 Days

One of Mobi’s greatest advantages is its extremely short installation time.
While stationary plants may take 2–3 weeks to assemble and commission, Mobi can be fully operational within 3–5 days.

All modules are pre-engineered with quick-connect points, pre-installed wiring, and piping systems, minimizing on-site assembly work.
This makes installation simple and efficient, requiring fewer technicians and no specialized heavy equipment.

This advantage is particularly valuable for projects requiring frequent relocation or short construction phases, saving significant time and setup costs.

3.4. Compact Design – Suitable for Various Terrains

The Mobi plant has a significantly smaller footprint compared to a stationary plant of similar capacity.
Its optimized structure ensures stability during operation while allowing easy movement across diverse terrains — from rural roads to hilly or space-constrained construction sites.

3.5. Fully Automated Operation – Safe and Labor-Saving

The Mobi plant’s control system integrates a Siemens S7-1200 PLC with HtenBatch automation software, allowing complete monitoring and control of the mixing process to ensure consistent concrete quality.

The operator simply:

1. Selects the mix design

2. Verifies the materials (aggregates, water, cement, additives)

3. Starts the automated mixing cycle

The system also features error detection, data logging, and auto-shutdown safety functions, ensuring reliability and operator safety.

3.6. Easy Maintenance, Cleaning, and Relocation

Thanks to its compact and modular design, Mobi is easy to maintain and clean.
Major components such as the mixer, conveyors, weighing systems, and sensors are easily accessible for inspection and replacement.

When relocation is needed, the entire plant can be lifted by its frame or a crane and transported safely.
The reinforced chassis structure guarantees stability and prevents vibration or misalignment during transport.

4. Mobi vs. Stationary Batching Plant – Comparative Overview

The Mobi plant is not intended to replace stationary plants but to complement them — serving as a flexible, cost-efficient solution for projects that require mobility, rapid setup, and reliable on-site concrete production.

5. Practical Applications

The Mobi concrete batching plant is widely used in:

• Rural and infrastructure projects (roads, small bridges, culverts, retaining walls)

• Residential and industrial zones (infrastructure and factory foundations)

• Remote construction sites with limited access to ready-mix supply

• Small and medium-sized concrete producers expanding their service areas

Using the Mobi plant helps:

• Reduce concrete transportation costs

• Ensure fresh, high-quality concrete at the job site

• Maintain supply flexibility when schedules change

• Reuse the same plant across multiple projects

6. Investment and Operational Benefits

For contractors and project developers, investing in a Mobi plant offers clear economic and operational advantages:

• Reduced operating costs: fewer workers, less downtime

• Long-term efficiency: easy relocation and reuse for future projects

• Consistent concrete quality: precise dosing and full automation

• Increased competitiveness: independent supply and production flexibility

With these advantages, the Mobi concrete batching plant is becoming the preferred choice for modern contractors pursuing efficient, rapid, and flexible construction solutions.

7. Conclusion

The Mobi concrete batching plant provides the ultimate solution for projects requiring high mobility — delivering superior performance in time, cost, and concrete quality.
Its non-dismantling mobility, fast installation, stable operation, and easy maintenance make it a reliable choice for all construction needs.
