During the process of manual coupling the air pipe connections between the two coaches are also established automatically. The pivoted joints between the coupler and the coaches is designed and constructed in such a way that even in case of maximum difference in level, the coaches are capable of negotiating all track curves and of passing through points of change of gradient occurring during service. This coupler fulfills all other operational requirements. SALIENT FEATURES OF ESCORTS SEMI-PERMANENT 1. Semi-permanent coupler can take up a compressed load of 100 tons and tensile load of 70 tons. 2. The dynamic absorption capacity of the rubber draft gear of these couplers is 800 m-kg. 3. Due to rigid connection of this coupler there exists negligible play between them in coupling position and hence no appreciable wear and tear during train operation. 4. Due to rigid and stress transmitting mechanical connection between the coaches by fitting semi-permanent couplers, protection to the coach and the load against undue impacts is secured. 5. Due to high draft capacity incorporated in semi-permanent couplers, it allows coaches to buffer at higher speeds (from 3 km/hr to 15 km/hr) without any damage to the coach and the load. 6. The interlocking arrangement of these couplers prevents to some extent the mounting or telescoping of the coaches when involved in accidents. 7. As the fulcrum of these couplers is located far in the rear of the coach, coupler side displacements in curves and consequently the transverse forces acting on the wheel flanges are kept minimum .This reduces the wear of the wheel flanges and minimizes the chances of derailment. 8. As the coupling links of semi-permanent couplers form a parallelogram with equilibrium of forces, unintentional disengagement of coaches due to shocks is rendered impossible. 9. The design and construction of the pivoted joint between these couplers and coach permits vertical deflection of ±75mm and horizontal deflection of 284 mm or 13º on either side and as a consequence enables the coaches to couple up at all track curves and also on points of change of gradient even at maximum height difference between the two coaches.
