JG150S 11ton Railroad Dual Head Tamping Machine For Railway Maintenance Excavator

The dual-head system can compact/tampe the sleepers on both sides of the track simultaneously, while traditional single-head equipment can only process one side at a time. This almost doubles the track area covered per unit time.

Modern dual-head tamping machines (such as the JG150S) typically employ a vibration frequency of approximately 35 Hz. This frequency has been proven to achieve maximum ballast compaction while avoiding excessive crushing or ballast damage.Deeper, more uniform ballast compaction contributes to improved overall track structure stability and load-bearing capacity, thereby reducing future maintenance frequency and costs.
