METHOD FOR MAINTAINING GAPS IN BEARER DURING REPAIRS OF FREIGHT CARS WITH TRUCKS Russian patent published in 2006 - IPC G01B5/00 

FIELD: railroad transportation, in particular, repairs of freight cars.

SUBSTANCE: method includes altering height of bearers of body bolster beam of car and truck bolster bearers base, determining required height (thickness) of inserts for caps of bearers, and provides normalized total gap in bearers on both sides of each end of car, includes measuring absolute values of height of bearers on bolster beam of car frame h₁ and truck bolster h₂, aforementioned truck repaired and prepared to fullering for the car. Then, formula is calculated and adjusting inserts are selected for caps of bolster bearers, required for provision of normalized total gap in bearers on both sides of each end of car. All necessary changes are performed using bearer height meter.

EFFECT: guaranteed provision of normalized total gap in bearers on both sides of each end of truck until fullering of truck for car, no need for repeated lifting of car superstructure, abolished delays in repairs and prevented low quality repairs.
