Welded rail clips can be fixed from the steel surface supporting the rail. This makes access requirements much easier during construction and when a crane is operational but being maintained.
Due to the compact design of some types the clips can be used with cranes fitted with guide rollers. All clips are adjustable but by amounts consistent with structural engineering design practice. It is normally a requirement to ensure the centre line of the rail passes within the thickness of the crane runway beam web.
The largest Gantrail clips can take a force of 300 kN from the rail into just one clip. This is because it is possible to lay down a large amount of weld metal around the base of the clip. However, the novel design of the clip ensures that it is still fully adjustable for 20 mm of horizontal movement of the rail.
Gantrail have welded base clips to fit all rail sizes including some that are no longer routinely made but are still found in some older applications. The size of the clip for any rail is in proportion with the rail it is designed to fix.
Gantrail have carried out extensive testing on clips to ensure that they will perform reliably and result in a long service life. This includes load tests on every model with external third party witness of tests and fatigue tests in third party laboratories.
Size for size welded clips give a stronger installation but bolted clips are often more convenient.
