The first in China and the third in the world to master this technology.....  DPG500type Rail Layer

DPG500type Rail Layer was an project of Railway Ministry Science and Technology Development Programs (project number:2003G09-B).It is a special large-scale automatic equipment designed to meet seamless tracks laying requirements for laying sleepers between original and new rails as well as laying long rails. And it is applicable to lay both ballast and ballastless tracks.

Design Features:

DPG500type Rail Layer adopts the method of laying sleepers singly in a row; this kind of constructing method saves rail-assembly site and related equipments, and can ensure to lay an accurate rail line especially when laying long rails on curved lines.

Main Technical Specifacation:

Rail-laying Efficiency: 12sleeper/min, 2rail-line/shift

Specifacation of Rail Laid: 500m, 60Kg/m

Laying Sleeper Precision: Space error between sleepers: ±20mm

                     Space error between every six sleepers: ±30mm

                     Deviation of orbit center and line center: ±20mm

Regulating Range of Space between Sleepers: 400mm-800mm(electronically adjustable)

Environment Requirements:


Wind power: ≤6

Altitude: ≤2000m

Sleeper Type: Type II and Type III

Applicable Curve Radius: ≥400m

Applicable Line Longitudinal Slope: ≤12%

Construction Speed: ≤100km/h

Short Haul Trial Speed: ≤32km/h

Curved Line Radius of Railroad Line: ≥180m
