Crack Grooving Machine for Roads

The dust control grooving machine can easily, accurately, and quickly create sealing grooves with a width of 1-5 centimeters and a depth of 0-3 centimeters along any seam on asphalt and cement road surfaces. Equipped with a vacuum cleaner greatly reduces the dust generated during cutting and protects the environment.

FND-K25Ⅱ

1. Adjustable cutting width & depth, compliant with municipal & highway crack-repair standards Cutting depth ranges 0-30 mm, cutting width adjustable 10-50 mm to produce neat standard repair grooves. Narrow-slot mode works for fine municipal cracks; wider cutting setting handles wide cracks and aged alligator cracking on highways, complying with various regional project specifications. The machine can precisely follow existing crack tracks without extra marking, delivering high-speed field performance.

2. Powerful imported Briggs & Stratton engine with 5-stage cyclonic air filtration for harsh-site reliability Equipped with imported Briggs & Stratton V-twin gasoline engine rated at 18.4 KW (25 HP). Sufficient power reserve avoids performance drop when cutting hard aged asphalt or concrete pavement. Five-stage cyclonic air filter effectively blocks heavy construction-site dust, reduces internal engine abrasion and extends service life for long-duration open-air field jobs.

3. Human-body trigger emergency braking system, 7-seconds fast stop for enhanced operator safety Built-in tilt-impact emergency stop switch. When operators slip or lose machine control, physical contact will trigger the brake mechanism and shut down the unit within 7 seconds. It greatly mitigates onsite personal-injury risks and meets western job-site safety requirements, critical for lane-occupying maintenance in city and highway.

4. Integrated 3 KW high-power dust-collector with airflow 260 m³/h for real dust-free eco-friendly construction Independent 3 KW dust-extraction motor delivers airflow of 260 m³ per hour. Stone powder and cutting debris are collected in real-time during routing with minimal site dust pollution. Groove interior is cleaned automatically, reducing manual post-cleaning workload. Ideal for densely-populated urban roads with strict environmental inspection rules.

5. Hand-push compact layout, easy maintenance and perfect compatibility with full repair workflow Hand-push mobility enables flexible relocation on busy urban roads and expressway working zones. Standardized components allow fast replacement of cutter discs. Grooves processed by this router are fully compatible with crack sealing machines and bitumen sprayers for seamless integration into complete crack repair production line.

Technical FAQ

Q1: What pavement types can FND-K25A crack router work on? A: It works for asphalt pavement as well as Portland concrete pavement. Built-in dust-collection unit for urban sites with strict environmental requirements for crack pre-treatment.

Q2: Can cutting depth and width be adjusted? What is adjustment range? A: Cutting depth:0-30 mm; cutting width:10-50 mm. Operators can set groove dimension according to actual crack condition on projects.

Q3: How does the emergency braking system function? A: The machine adopts tilt-impact trigger switch. When operator loses balance and collides with the switch, machine will stop operation within 7 seconds for operator safety.

Q4: What is airflow rate of dust-collector? Can it clear debris inside groove? A: Dust-collection airflow reaches 260 m³/h. It captures surface dust and inner-groove debris during routing and greatly reduces post-routing cleaning workload.

Q5: What is the advantage of Briggs & Stratton engine air filter? A: Five-stage cyclonic air filtration greatly filters dust and impurities under high-dust routing site conditions, reduces engine wear and extends service life under harsh working environment.
