The Pyongyang Trolley Bus Factory has introduced several new technologies into production.
Among its facilities made with the new technologies is a multipurpose shaped steel bending machine. Based on the cooling-bending method, the machine can bend various kinds of shaped steel to any angle. With the introduction of the new bending machine, the factory saved labour, materials and funds, reduced the production cycle to one fourth and doubled the trolley bus framework production capacity.
It remodelled previous fixed front frame jig into compressive front frame flexible jig, which made it possible to make any kind of frame with less effort and materials.
“Our factory’s portable rotary machine speed indicator is a very practical wireless device that can measure the speed of any rotating object within one-metre range and thus helps prevent different accidents and repair broken motors properly and quickly,” said senior engineer Kang Chol.
Besides, it has improved the quality of the trolley bus painting process by adopting a painting method based on far infrared heater and also introduced over 10 kinds of technical innovation plans such as the establishment of a power-saving core-type induction furnace and a trolley bus lighting testing process using screen.
