Skewing in EOT Cranes is due to non synchronisation of Long Travel motors in case of twin motor drives. If it is central drive for L.T then it can be due to misalignment of L.T wheels. You have to check the diagonals of the wheels, all the wheels should be in line with L.T rails, also there should be minimum clearance of 5 mm between rails and wheels. There can be many such reasons. It will be better to approach crane mfr to sort out this problem.
