57-Type Crawler Road Cutting Machine — Practical, Patented, Jobsite-Ready

Introduction 

The 57-type Crawler Road Cutting Machine is our patented solution for reliable, straight and fast pavement cutting. Built around a four‑cylinder 490K engine and an electric‑control drive (24V) with remote operation, this crawler‑mounted cutter measures 2200 × 1160 × 1400 mm and weighs 700 kg. It cuts up to 30 cm deep and is designed for single-cut spacing of 50–100 cm, making it ideal for municipal road repair, runway maintenance, utility trenching and renovation projects where steady, accurate cutting is required.

Key features (what you get)

• Diamond blade cutting: Uses diamond segments for fast, clean cuts and the ability to cut through reinforced concrete and embedded steel.

• Onboard water spray: Built‑in water tank and spray system cool the blade, suppress dust and lengthen blade life.

• Rigid box‑style frame: A super‑rigid chassis resists warping and vibration for straighter cuts and longer service life of the saw and blade.

• Electric control + remote operation (24V): Remote control keeps the operator at a safe distance while electric drive ensures smooth, precise movements.

• Ergonomic & service friendly: Adjustable handle height, depth crank, front‑hinged blade guard and quick‑connect water fittings for easy blade changes and maintenance.

• Crawler mobility and stability: Even weight distribution (700 kg) gives stable traction on uneven pavement.

• Patented design: This 57 model incorporates patent-protected features developed for real jobsite needs.

Frequently asked questions (real questions we hear)

Q: What materials can the 57 cut? A: With the correct diamond blade you can cut concrete (including reinforced concrete), asphalt, precast concrete elements, granite, marble and brick. Always match blade type to material for best life and performance.

Q: How deep and how close can I cut? A: Maximum cutting depth is 30 cm (300 mm). For single‑cut operations follow the recommended spacing of 50–100 cm depending on breaking method and the pavement structure.

Q: Is water required during cutting? A: Yes. The onboard water spray cools the blade and suppresses dust — essential for extending blade life and keeping the work area safer and cleaner.

Q: How is the machine powered and controlled? A: The prime mover is a four‑cylinder 490K engine; motion control is electric (24V) with remote control operation, so you get engine power with precise, safe control.

Q: Can I use it where there’s no site power? A: Absolutely — the engine provides full independence from external electricity. The machine’s electric control runs from the onboard 24V system.

Q: What about maintenance and blade replacement? A: The 57 model is designed for field maintenance: front‑hinged blade guard, quick‑connect water hoses and a simple structure mean blade changes and routine checks are quick and tool‑friendly.

Q: Any important safety reminders? A: Yes — check motor, cables and grounding before use; run an empty‑load test to confirm blade direction and smooth operation; never feed material with loose gloves; when the workpiece is within 300 mm of the blade or cutting small pieces, use push tools instead of hands; stop and inspect at any abnormal noise or vibration; ensure ventilation in enclosed areas; shut off engine before refueling and avoid smoking or open flames nearby.
