H-Type Coupler Model to impart training of Coupling & Uncoupling

Summary

Fully fledged working trolley of H-Type Coupler on track is prepared at DTTC-RTM to impart training to Running staff, Operating staff and shed maintenance staff.

Detailed description

Previously, repeated cases of Loco not coupling/uncoupling with load were happening at stations and yards due to lack of knowledge of Operating / Running staff and consequential detention of train / punctuality loss had been taking place. Moreover this problem had been creating a lot of inconvenience in those places like Chittaurgarh, Indore & Ratlam yard in Ratlam Division of WR, where RR has to be performed frequently to meet the operational requirements.  Many times coupler lock pin got damaged and loco parted from train while starting. Since operation of H-Type Coupler is to be practically demonstrated to all the staff, there was limitation of time, place, duration and practical operation constraints in the yard and as such, training was not getting properly imparted.

To overcome above issues and to ensure training of all the concerned through supervisors with physical demonstrations of all the subassemblies and procedure of  assuring proper coupling, a  fully fledged working trolley of H Type Coupler is made at DTTC, Ratlam (WR).

Two H-type coupler one fixed to the structure and one moveable on trolley is placed on rail, has been developed. By moving trolley the operation / function of coupling, parts involved in coupling, proper coupling and decoupling operations etc.  can be easily demonstrated to trainees.   All the important aspects while performing H-type coupler operation like dropping of lock lifter, clearing of tell tale slot of rotary lock lift lever, vertical position of rotary lock lifter rib, parallelism of Knuckle & coupler head machined faces, proper fitment of lock pin of coupler etc. are demonstrated. With the introduction of training on this model, the knowledge of all the concerned staff has improved drastically which is helping in reducing the cases of decoupling in yards during attachments. 

Impact / Benefit

Help to reduce MMBC & BWMS cases pertaining to H-type coupler significantly and thus enhanced the safety of train to avoid train parting and accident cases.
