DWL-48 Continuous movement tamping and stabilizing machine

The DWL-48 Continuous Action Tamping and Stabilizing Machine can achieve the continuous three-sleeper tamping operation and stabilize the power of railway. In contrast with the two-sleeper continuous tamping machine, it enhances the working efficiency by approximately 30% ~ 40% . By virtue of the additional compound controlling track stabilizer, the tamped railway directly obtains a quite high precision and sufficient stable performance, and this allows the high-speed and full-load operation of railway after the railway is officially put into use.

The DWL-48 Continuous Action Tamping and Stabilizing Machine employs a three-sleeper tamping device, which can simultaneously tamp three sleeper during the course of working. In addition, this device is separable in structure so as to allow the tamping operation despite the uneven sleeper spacing and the complicated zone, and may be widened in accordance with requirements. If necessary, it may be used as a high-performance one-sleeper tamping machine. The flexible optional configuration of tamping device boosts the maneuverability and adaptability of whole machine.

The DWL-48 Continuous Action Tamping and Stabilizing Machine uses two DEUTZ water-cooled engines as the power source. During the course of high-speed travel, this machine utilizes the mode which combines mechanical transmission and static hydraulic transmission. Such a reasonable transmission configuration helps to save energy. Furthermore, a series of advanced technologies, such as the bi-dimensional laser measuring system, the double-hydraulic-drive-shaft bogie for working trolley and the new electric drive system, are provided for the machine. The model filled the gap in this field domestically, bringing the large-scale road maintenance machinery produced in China a world-class player. The machine plays an significant role in the nationwide railway speedups.
