Zdas CDR 500 Hydraulic railway press 

Presses designed to mount and dismount railway wheel sets

The CDR press is designed to cold press on/off the railway wheel sets with guide bushes. The equipment enables to mount and dismount the
wheel sets for engines and railway wagons, while recording the pressing force course depending on the pressing length. After the pressing has
Ьeeп completed, a protocol is printed in order to file the process.
The press is of a horizontal three-column design that avoids press thwarting due to eccentric action of the force and guarantees exacl perpendi-
cularity between the wheel pressed and the pin. The press cylinder leans against the supporting traverse, which wheels travel along two beams.
Pressing force is taken up by the supporting traverse in locking positions given in advance depending on the type of the wheel set.

Reference:
For needs of railway
wagon repaır shops, several
CDR 500 hydraulic presses have been supplied
that serve to cold press on/off the travel wheels of railway
engines and wagons. Among the last successful references ranks the supply
of this equipment to one of the prominent Chinese manufacturers of railway engines
and wagons in a town of Qingdao.
