1. Adjustable Grooving Accuracy to Reduce Re-work Cost Cutting depth 0-30mm and cutting width 10-50mm are continuously adjustable. It produces well-formed standard repair grooves along existing cracks on both asphalt and concrete pavements. Better groove shape enables stronger bonding with crack sealant, lowers re-cracking risks and saves your material cost and labor hours from rework.

2. Human-triggered Emergency Brake Prevents Accidents and Downtime Losses Equipped with human-body triggered emergency brake system. The machine stops within 7 seconds once touched by off-balance operators or under machine tilting. It effectively avoids safety accidents during hand-push operation, cuts injury risks and prevents project shutdown or compensation losses caused by safety incidents.


3. Built-in Dust Collector on FND-K25A: Pass Local Environmental Inspection and Avoid Penalties FND-K25A is equipped with a 3KW dust collector with 260m³/h air flow rate. It absorbs cutting dust in real-time during grooving. Greatly reduced site dust meets overseas municipal environmental requirements, helping you avoid fines for excessive dust and improve working conditions for operators.

4. Optimized Counterweight & Large-capacity Fuel Tank: Minimize Downtime and Boost Project Delivery Efficiency Weighing 225-245KG with well-balanced counterweight, the machine runs steadily without deviation during hand-push operation. The 25L large-capacity fuel tank supports long-hour continuous work without frequent refueling. It helps shorten construction periods, complete more grooving tasks within limited working hours and speed up project delivery.

5. Two-model Flexible Selection to Control Your Procurement Budget Choose FND-K25 for basic grooving tasks on regular sites. Select dust-collecting FND-K25A for municipal projects with strict environmental rules. You pay only for functions you actually need, optimizing your equipment investment.



Project Location: Al Quoz Municipal Road Maintenance Project, Dubai, United Arab Emirates

Project Background: Multiple main municipal roads in Al Quoz, Dubai developed extensive network cracks on asphalt and concrete surfaces due to long-term high-temperature exposure and heavy-vehicle traffic. Local authorities impose strict dust-control regulations with heavy fines for violations. Meanwhile, the project was under tight construction schedule. The contractor required equipment balancing working efficiency, operator safety and environmental compliance, and finally selected FND-K25A crack router.

Application Performance: Working on both asphalt and concrete pavements, the machine was set at cutting depth 0-25mm and cutting width 12-20mm to generate well-shaped repair grooves along original cracks. The integrated dust collection system captured cutting dust on-site, kept dust levels within limits and helped pass local environmental inspection without fines. The machine maintained stable performance under 45℃ high ambient temperature. The emergency brake system protected operators and prevented safety-related work stoppages. Approximately 1200 meters of crack grooving was completed per working day. Groove quality satisfied sealing requirements and ensured good sealant adhesion, greatly lowering future re-repair risks. The contractor finished pavement defect pre-treatment on schedule and delivered the project successfully.
