PURPOSE: A carrier for a traveling reducer in heavy construction equipment is provided to maintain carrier performance for a long time use by receiving a load along the longitudinal length of a planetary gear fixing member. CONSTITUTION: A carrier body(23) comprises a spline connector, a plurality of pin coupling holes and a ring settling unit. The carrier body is combined with a spline on one side of a sun gear through the spline coupling unit and rotatably supports a planetary gear. A planetary gear fixing member(20) is axially coupled with the pin coupling hole formed on one side of the carrier body and rotatably supports the planetary gear. A pin fixing member(26) is coupled with one side of the outer surface of the planetary gear fixing member and fixes the planetary gear fixing member. A compression ring member(30) is mounted on the ring settling unit. The compression thrust ring member prevents the separation of the planetary gear fixing member.
