E-clip installation machine
12297604 · 2025-05-13 ·

An e-clip installation machine for securing rails to steel ties via automating and reducing the time required for installing e-clips that attach rails to steel ties is provided. The e-clip installation machine automates the process of securing rails to steel ties via inserting e-clips into a respective shoulder clip on either side of the two rails. A pair of hydraulic jaws clamp the steel tie and bring it up against the underside of the rails. Two e-clips for each rail are placed in position at the respective shoulder clips. Two pairs of hydraulic clamp mechanisms, corresponding to each rail, press the respective e-clips through openings within the respective shoulder clips. The e-clip installation assembly includes a jaw assembly and two clamp assemblies. Each clamp assembly includes a pair of clamp mechanisms, positionable on either side of a rail in proximity to a shoulder clip affixed to a steel tie. A clamp mechanism is utilized to compress an e-clip within an opening of the shoulder clip.
