Abstract:
A device for laying sleepers on a ballast-bed for railroad construction includes a body having a commuting-mechanism and a fork-lift on a first side of the body The fork-lift lifts and holds at least one set of sleepers above the ballast-bed. A pair of pivot-arms are movably coupled the body and include a gripper. The gripper moves a set of sleepers from the fork-lift from the first side of the body towards a second side of the body. A cradle-arrangement mounted on the second side of the body and the commuting-mechanism allow movement of the device. The pair of elongated fixed support-members is configured to support the set of sleepers moved by the grippers The pair of movable support-members has a reciprocating-movement with respect to the pair of elongated fixed support-members to successively release one sleeper of the set of sleepers at a time from the pair of elongated fixed support-members.
