CZK - vz.53 (železničný podvozok)

New Topic
The lightweight dismountable unsprung railway chassis vz.53 is designed for transporting track spans on wooden sleepers ( up to 30 m long ) and bridge trestles ( up to 26 m long ) on normal gauge tracks.


The load is always stored on two bogies. The relative position of the bogies is maintained by the load rubbing against the support surfaces.


Chassis design


The support section is welded from profile steel and steel plate. Because the chassis is unsprung, its service life is limited.


Chassis assembly


- 4 idler wheels mounted in the sidewalls,
- 2 siderails,
- 2 crossmembers connecting the siderails to the coupling.



Main technical data :


Dimensions in mm:


Wheelbase : 1000
Wheelbase : 1435
Wheel diameter : 400
Height of loading area above top of rail : 745


Weight kg :


Chassis with main cross member : 1100 / without 850


Max. Speed in km/h :


- Bridge provisional : 15
- track gauge : 30

Rail chassis vz.53 and vz.53i are low unsprung chassis designed for transporting self-supporting loads on normal gauge railway lines. The bogies are mainly intended for the transport of track spans of max. 30 m in length during the construction and repair of railway superstructure. After simple adaptation, they can also be used to transport IP beams. The track fields are stacked on the two highest bogies in five layers symmetrically so that they show minimum deflections. The distance between the bogies must not exceed 17 m.


The actual weight of the load per bogie must not exceed 32 t for the Model 53, then 36 t for the Model 53i.


The bogies are not equipped with brakes. The relative position of the chassis when carrying loads is maintained by friction of the load on the storage surfaces. When passing through a curve, the chassis design allows mutual displacement of the chassis sides by up to 100 mm.


The chassis are completed with accessories, accessories for transporting IP beams, mounting and measuring aids.


The railway chassis vz.53 is of older production, the new chassis vz.53i has a 4 t higher load capacity. The principle of the overall arrangement of the vz.53 and vz.54i chassis is identical.



Main technical data :


Dimensions in mm:



Gauge : 1435
Width : 1000


Wheel diameter : 400



Height of the storage area above the top of the rail : above the top of the rail. 53 - 810 mm / vz.53i - 788 mm


Load capacity : vz.53 -32 t / vz.53i - 36 t


Weight in kg :


vz.53 - 945 / vz.53i - 800


Max. speed limit : 30 km/h.


Chassis life 12 years.
