The Pyongyang Trolley Bus Factory has recently produced trolley buses which would contribute to passenger service in the capital city.
This year, technicians of the factory invented and introduced new technical innovation plans, thus laying foundations for increasing the production of trolley buses.
They made a general motor assembling jig to ensure precision in the assembly of motors and save much labour and time.
They also renewed the motor coil insulator winding equipment to prolong the serviceable life of motor coils.
“We are producing trolley buses more efficiently as compared to before by positively introducing new technical innovation plans. In the near future, the trolley buses produced at our factory will promote the rapidness and convenience of passenger service in the capital,” said Phyo Hyok San, chief engineer of the factory.
