A concrete curb machine is a heavy-duty road construction equipment used for continuous, one-time pouring of concrete curbs on-site. It replaces traditional precast methods. The machine uses spiral blades to push concrete into a forming mold, combined with high-frequency vibration to ensure concrete density.
In today’s market, this equipment is vital for highway shoulder curbing and urban road median installation. It handles straight lines and complex curves with ease.
Pro Tip: When buying, check the steering precision. Poor machines often deviate by more than 10cm on curves.

Why Choose YG Slipform Concrete Curb Machine?
Our KB20 and KB30 series represent a real change in performance.


1. Patented Dual Automatic Steering System
Most competitors use single steering. The YG concrete curb machine uses dual automatic steering. This reduces position deviation on curves by over 95%. It ensures the pavement width stays exact.
2. Exclusive Anti-Slip Self-Locking Function
During stormwater gutter formation, slopes are a major challenge. Our machine requires no manual braking on uphills or downhills. It automatically maintains the set speed. This removes the risk of “sliding,” ensuring safety.
3. Strong 4WD and Power
Equipped with a 65kw four-cylinder turbo diesel engine. When the longitudinal slope is < 5%, it can push a fully loaded 18-cubic-meter tanker. This is essential for airport runway edge drains.
Wide Applications and Industry Cases
The concrete curb machine is more versatile than you think:



- Municipal Works: Used for parking lot perimeter curb and city medians.
- Infrastructure: Fast completion of drainage channel edging and extruded curb machine tasks.
- Special Structures: Ideal for landscape curbing machine styles or jersey barrier blocks.
Success Case: Saudi Arabia New City Project
Our client, Ahmed, managed a large industrial zone in Saudi Arabia. High temperatures and tight deadlines made manual concrete curb and gutter machine installation impossible.
He imported the YG-KB30 crawler model.
- Problem Solved: Overcame labor shortages and concrete cracking issues.
- Result: Paving speed reached 10m/min, 12 times faster than manual work.
- Data: The project finished 20 days early, saving $45,000 in labor costs.
Concrete Curb Machine Frequently Asked Questions
Our screw feeder uses a high-torque hydraulic motor with wear-resistant coated blades. It prevents clogging. We recommend aggregate sizes between 5-16mm.
No. We use two-stage cooling (water and air). This keeps hydraulic oil temperatures low, extending the life of pumps and motors.
