DCW 2.2 Binder Spreader

Dual Roller System

Two internal rollers enable flexible switching between 2-meter full-width or 1-meter individual-section spreading, adapting to any project layout.

Electronic Dosage Control

Integrated control system with a cab-mounted display allows the operator to fine-tune application rates in real time, ensuring consistent uniformity.

Front-Mount Design

Mounted at the front of the tractor, the DCW 2.2 lets you spread binder and immediately stabilize the soil in one single operation pass.

Lime & Cement Compatible

Designed specifically for distributing lime or cement binders in soil stabilization works, replacing inefficient manual bag-spreading methods.

Minimal Material Waste

Uniform application with minimal waste significantly outperforms the conventional "bag-spread" manual method, reducing material costs per project.

Heavy-Duty Steel Frame

The entire body is constructed from high-tensile structural steel, designed to withstand the vibration, dust, and mechanical loads of continuous field operation without deformation.

Variable Flow Gate Control

A motorized flow gate precisely regulates the volume of binder released per unit of travel, responding in real time to operator input from the cab display panel.

Counter-Rotating Rollers

The two internal rollers rotate in opposing directions, breaking up clumps and creating a fine, even curtain of material across the full working width for superior uniformity.

GPS Speed-Linked Dosing

The electronic system continuously adjusts the flow rate based on the tractor's ground speed, maintaining a constant application dose per m² regardless of terrain or speed variation.

Sealed Bearing Assemblies

All critical bearing points are factory-sealed and protected against lime and cement dust ingress — significantly extending service life and reducing maintenance intervals in aggressive environments.

Modular Section Shutoff

Each 1-meter roller section can be independently engaged or disengaged from the cab, enabling precise section control to avoid overlapping or over-application at field boundaries.

Tool-Free Hopper Access

The large-capacity hopper features quick-release access panels for cleaning and inspection, minimizing downtime between material changes from lime to cement or vice versa.

Digital Application Log

The onboard controller records total area treated, material consumed, and average application rate — providing accurate data for project reporting and material reconciliation.

Front-Mount & Connect

Attach the DCW 2.2 to the tractor's front three-point linkage. Connect hydraulics and plug in the cab display harness.

Load the Hopper

Fill the hopper with lime or cement binder. The large opening accommodates both bulk bags and pneumatic delivery.

Set Dosage Rate

Enter the required application rate (kg/m²) and select 1 m or 2 m width on the cab display. The system auto-calibrates flow accordingly.

Spread & Stabilize

Drive forward. The DCW 2.2 spreads binder at the front while the rear-mounted stabilizer mixes it into the soil in the same pass.

Monitor & Log

The display shows live usage data. On completion, retrieve the digital log for project records and compliance reporting.

Application Versatility

1 m or 2 m spreading widths selectable on the go — ideal for narrow paths and full-width roads alike.

Integrated Electronic Control

Precise adjustment by the operator from the cab display — no guesswork, no over-application.

Single-Pass Operation

Distribution and stabilization completed in one pass — cutting project timelines and equipment costs dramatically.

Efficiency & Economy

More uniform application with less waste compared to manual methods — proven savings on material and labor costs.

Highway Sub-Base Preparation — Bavaria, Germany

Road Engineering · 2023

A German infrastructure company used the DCW 2.2 for a 12 km highway segment. The electronic dosage control minimized cement over-application, cutting material costs by an estimated 22%. Soil bearing capacity reached target values in under 72 hours, meeting European construction standards ahead of schedule.

Agricultural Access Track Upgrade — NSW, Australia

Farm Infrastructure · 2022

A large-scale grain farm upgraded 25 km of internal access tracks using the DCW 2.2. The 1-meter section option allowed precise treatment of narrow paths without waste. Material savings exceeded 18% versus the previous manual lime-bag method, and track durability improved noticeably through two wet seasons.

Mine Site Road Maintenance — Gauteng, South Africa

Mining Logistics · 2024

A surface mining operation stabilized 30 km of heavy-haul roads using cement binder distributed by the DCW 2.2. The front-mount configuration allowed the stabilizer head to follow immediately, reducing the number of machine passes. Road dust suppression and load-bearing performance both improved measurably over the 6-month monitoring period.

Coastal Erosion Control — Normandy, France

Civil Engineering · 2023

A French civil engineering firm stabilized coastal embankments using lime distributed by the DCW 2.2. The selectable 1 m width enabled precise treatment of narrow paths in sensitive environmental zones. Fuel consumption averaged 19 L/hr, and the project came in under budget by approximately 15% versus the original manual spreading estimate.

Rural Road Program — Rajasthan, India

Government Infrastructure · 2024

A state road authority contractor utilized the DCW 2.2 on a rural connectivity program covering over 40 km. The machine's electronic control allowed operators to adapt dosage rates to varying soil conditions across the route. Labor requirements dropped by an estimated 35% compared to traditional bag-and-rake spreading methods.

"The DCW 2.2 cut our spreading and stabilization time in half. We used to run two separate passes — now one tractor does both jobs. The cab display is easy and intuitive. Our crew picked it up in a day."

James Hartwell

Road Construction Contractor · Queensland, Australia

"Very impressed with the uniformity of lime distribution. On previous projects we wasted 15–20% of material due to manual spreading. With the DCW 2.2 that waste is almost eliminated. The 1-meter mode is perfect for our narrow farm tracks."

Maria Fernández

Civil Engineer · Andalusia, Spain

"We operate on a large mining site with heavy-duty haul roads. The DCW 2.2 handles both lime and cement perfectly. The front-mount position means we stabilize immediately after spreading — the roads hold up much better now under our 80-tonne trucks."

Thabo Dlamini
