Rail Anchors For Heavy Rail Tracks Stable Mechanical Property And Preventing Longitudinal Movement
Rail anchors or called rail anticreepers are spring steel clips that attach to the underside of rail tie plates and bear against the sides of rail sleepers. The function of rail anchors is to prevent longitudinal movement of the steel rails, either from changes in temperature or through vibration.

For heavy rail tracks such as 50kg, 70lb, 80lb, 90/91lb, best option for steel material is 60Si2MnA, based on our former production experience and customer feed back, this material shows more stable mechanical property than most common material for rail anchor production is 60Si2MnA.
Application Rules of Rail Anchors
Rail anchors should be on the gage side of the rail base against the same tie face on opposite rails.
Rail anchors have to hold the rail base tightly and firmly and have full bearing against rail tie face.
A new rail anchor and a rail tie will be needed when the bearing of rail anchor against the tie has been disturbed.
Anchors shall not be moved by driving them along the rail.
The rail ties should be kept straightened when the anchors are applied.
