Document Type and Number:
WIPO Patent Application WO1999031322
Kind Code:
A9
Abstract:
A rail restraining (1) and weld delivery device (100) uses a frame for supporting a welding head with a clamp (3) for restraining a first rail end and a second rail end and a base twist assembly (17) for aligning said first end and second end. An interconnected weld containment apparatus (290) pivotally connects to the clamp by use of a cam actuated linear pin (7). This arrangement is operable in an environment in which clearance between rails is about 7 to 11 inches and sufficiently compact that it may be operated from and carried in a truck based on a standard over the road truck.
