Road construction machines for Crack repairing

The Road Slotting Machine (model LS-200Slotting) is designed for precision grooving and crack preparation on asphalt and concrete surfaces — ideal for slotting prior to crack filling, sealing and joint repair.

Model LS-200Slotting; 18 HP gasoline engine; slotting speed 5–20 m/min; cutting depth 0–80 mm; cutting width 10–50 mm; four cutting blades (blade diameter 180–200 mm); weight 156 kg; overall size 1580×750×1150 mm; moving method: pull; start: hand pull; fuel: petrol.

Cutting depth is adjustable from 0 up to 80 mm and cutting width can be set between 10 and 50 mm, allowing flexible slot sizes for different crack-repair materials.

It is powered by an 18 HP gasoline (petrol) engine with a hand pull start.

The unit uses four cutting blades. Blade diameter compatibility is 180–200 mm. For best results use manufacturer-recommended blades matched to the surface material.

Yes — the machine is engineered for high-performance cutting on both asphalt and concrete surfaces for grooving and crack preparations.

The machine weighs 156 kg and has compact dimensions for good maneuverability on site. It is moved by a pull method; for transport between sites a small vehicle or trailer is recommended.

Routine maintenance includes cleaning debris after use, inspecting and tightening bolts, checking and replacing worn blades, monitoring engine oil and air filter, checking spark plug and fuel system, and lubricating moving parts. Regular checks minimize downtime and extend service life.

Blade replacement depends on material hardness, frequency of use and operator technique. Inspect blades before each shift for wear, chips or cracks and replace when cutting performance or safety is compromised. Contact your supplier for spare blades and part numbers.

Recommended PPE includes safety goggles or face shield, hearing protection, dust mask or respirator, cut-resistant gloves and safety boots. Always shut off the engine and disconnect spark plug before servicing, secure loose clothing, and follow local safety and emission regulations.

Standard inclusions are not specified in the general description. Typical items may include a set of blades, basic tools and an operator manual. Contact sales for an exact list of included accessories and optional kits.

Yes — the adjustable width (10–50 mm) and depth (up to 80 mm) make it suitable for preparing slots for a variety of crack sealants and fillers. Confirm slot size requirements with your material supplier for best results.

On-site training and after-sales service availability vary by supplier and region. Contact the manufacturer or dealer to ask about commissioning, operator training, maintenance services and spare-parts support.

The machine is powered by a gasoline engine so it will produce noise, dust and exhaust emissions. Compliance with local noise and emission regulations depends on your jurisdiction; use dust extraction or water suppression where required and wear appropriate PPE. Check with your supplier for quieter or emission-controlled engine options if needed.

Please contact the manufacturer or your local dealer to request pricing, lead times, shipping options and spare parts. The sales team can also provide customized quotes, accessory bundles and information on warranty and service plans.
