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.
