WELDING APPARATUS AND METHOD FOR RAILWAY TRACK RAILS

摘要

A machine for welding the rails of a track includes a rail pulling device (12) that grips the rail ends (4) and pulls them together so that they can be welded to one another. Two rail clamps (22) provided for gripping the rails (4) are fastened to the rail pulling device (12). The rail clamps are each vertically adjustable in their position relative to the rail pulling device (12) by way of a respective adjustment drive (23) in a direction extending perpendicularly to a pulling device plane formed by hydraulic drives (20) of the rail pulling device. With this, the rails (4) can be lifted from ties in a simple manner in order to enable the clamping members (17) of the rail pulling device (12) to grip the rails (4).
