Product / 20 T Crane

20 Tone Diesel Crane is a Rail Mounted, Diesel operated, BG (Broad Gauge) transportation crane. The crane is extensively used by Mechanical Department of Indian Railway in sick lines for maintenance of wagons/coaches and Transportation Department Indian Railway for handling of Goods.

First 20T Diesel Crane was manufactured in 1980-81, and total 4 nos. were manufactured upto 82-83 with mechanical control system.

Later the control system was changed to Pneumatic as per RDSO Specification No. CR.D.122/90. Since 89-90 the shop has been manufacturing the 20 Tonne cranes as per this specification and has manufactured many such crane.

 

Future Planning:

There are a total of 16 20T cranes sanctioned in the RSP. Out of these 8 nos. for ER has already been taken under manufacture and is scheduled to be turned out during 2002-05. 

For the rest cranes a design of 20T Hydraulic crane has already been finalized by Jamalpur in consultation with RDSO. All future production of the cranes will be done as per the new design subject to success of prototype of the first crane.
