Crack sealing machine is a road maintenance machine for repairing the pavement cracks, which is used for heating and pouring the sealant evenly into the treated cracks to achieve the waterproof purpose. It’s composed of chassis, power, driving motors, control system, heating system, and pumping systems. It’s used with a router, vacuum cleaner, or hot air lance. It applies to the residential, municipal, highway, freeway, airport, and other pavement.


Features

1. Centralized temperature controller: Dual-digital liquid crystal temperature controller: timely display and adjust the temperature of heating transfer oil, sealant, and sealing hose.

2. Sealing wand: Electric discharge switch controls the material volume, ensure the best sealing effect. Easy to replace sealing wand make sure the best effect according to different cracks. 

3. Heating transfer oil system: The sandwich design uses less oil, improves heating speed, and reduce replacement cost.

4. Special geometry chamber: The flame blow to the partition wall at an angle of 45 degrees downwards, without direct contact with a hot kettle, the air in the chamber is fully burned with a high heat utilization rate.

5. The lowest feeding height: Compact and reasonable structure, low operating position, and filling height ensure conveniently, labor-saving, and safe feeding operations.

6. Chassis: Dual shock absorber towing chassis; safe driving; Parking brake; self-propelled or and towing. 

7. Engine: Reliable Honda gasoline engine-generator.
