Machine and method for welding rails of a track

摘要

A machine for welding the rails of a track includes a rail pulling device that grips the rail ends and pulls them together so that they can be welded to one another. Two rail clamps provided for gripping the rails are fastened to the rail pulling device. The rail clamps are each vertically adjustable in their position relative to the rail pulling device by way of a respective adjustment drive in a direction extending perpendicularly to a pulling device plane formed by hydraulic drives of the rail pulling device. With this, the rails can be lifted from ties in a simple manner in order to enable the clamping members of the rail pulling device to grip the rails.
