The device leverages 35Hz high-frequency vibration to rapidly disrupt the compacted structure of ballast particles. This process encourages particles to re-interlock into a tighter configuration, significantly boosting the ballast bed’s density and load-bearing capacity. Compared to low-frequency alternatives, this technology minimizes ballast fragmentation and ensures long-term stability.
The tamping picks are engineered to insert below the bottom surface of sleepers, fully compacting the ballast directly under the sleeper. This eliminates the risk of "shallow false ballast"—a common issue that leads to premature track settlement. By targeting the root cause of settlement, the DWL-48 reduces the need for follow-up maintenance.
Integrated with track lifting and shifting functions, the DWL-48 corrects key geometric parameters (level, height, direction) in real time while tamping. This synchronization minimizes secondary disturbances to the ballast bed, ensuring that the track remains aligned and stable immediately after operation.
Adopting a separable three-track sleeper tamping design, the device processes three sleepers simultaneously in a single operation. This structure improves work efficiency by 30%-40% compared to traditional double-sleeper tamping machines, making it ideal for large-scale track maintenance projects.
