Incorrect Operating Sequence
1. Starting with Vibration Immediately: The correct operation is to start the road roller smoothly and allow it to run stably before activating the vibration function.
2. Arbitrarily Adjusting the Vibration Frequency During Compaction: The vibration frequency should be set before operation and should not be adjusted arbitrarily during compaction.
3. Activating Vibration on Hard Surfaces: It is strictly forbidden to use the vibration function on hardened surfaces, otherwise it will cause equipment resonance and damage.
Safety Regulations Violation
1. Improper Operation on Slopes: When going up or down slopes, a low gear must be used (speed controlled below 7 km/h). Shifting gears or coasting in neutral on slopes is strictly prohibited.
2. Insufficient Spacing Between Multiple Rollers: When multiple road rollers are operating together, the distance between them should be at least three times the vehicle speed, and no less than 5 meters.
3. Rolling Edges Too Closely: When rolling the edges of soft roadbeds, a safety distance of at least 0.5 meters should be maintained, and pre-compaction should be performed first. Maintenance Negligence
1. Neglecting daily inspections: Starting work without checking tire pressure, parts condition, and the surrounding environment can easily lead to accidents.
2. Failure to clean tires promptly: Asphalt particles adhering to tires must be cleaned promptly, otherwise it will affect equipment performance.
3. Delayed fluid changes: Failure to change engine oil, brake fluid, etc., on schedule may lead to serious equipment damage.
Improper Speed Control
1. Excessive compaction speed: Compaction speeds exceeding 4 km/h can easily lead to uneven road surfaces or the risk of rollover.
2. Sharp turns: Turning speed must be slow. When turning with your toes, the speed should not exceed 3 km/h, and sharp turns are strictly prohibited.
Incorrect Handling of Special Working Conditions
1. Using rubber-tired rollers for SMA surface layers: This type of asphalt mixture requires vibratory rollers. Rubber-tired rollers will cause the asphalt binder to float, damaging the road texture and anti-skid properties.
2. Operating with faults: If abnormal pressure is found in the hydraulic system, the machine should be stopped immediately for inspection. It is strictly forbidden to continue operating with faults.
