Mine custom fishplates, Linzhou Zheng iron (certified), mining fishplates

Railway Turnout: Turnout diffuse locked. In the turnout unit welding is completed, the machine raising operation is completed, and the track bed density, the track surface elevation, and horizontal rails have to meet the design criteria of mine fishplates manufacturers conduct turnout relief, locked. Bleeding turnout locking conditions: two docking turnout turnout heart relative distance, line spacing accurate. Heart rail, rail tip and tip retainer bit Ge correctly. Turnout laying: Turnout zone bottom ballast rolling. To ensure that the density of the track bed of the turnout area, after the pre-stratified shop using roller compacted laying ballast thickness 27cm mine fishplates manufacturers, turnout bottom ballast after rolling is completed, be used to detect the density of the sand replacement method, compaction density of not less than 1.7g / cm3; ballast surface flatness ruler with 3m mine inspection fish plates, each direction of error should not be greater than ± 5mm. Compaction density of not less than 1.7g / cm3, aside from the road shall not exceed 50mm, ballast surface flatness tolerance of 10mm / 3m.
