How to install Jinghong top drive guide rail

Use more than 400 Taipei division top drives. There are Beishi top drives in PetroChina, Sinopec, CNOOC, BP, Royal Dutch Shell, Chevron, Total and Schlumberger projects. Beijing Normal University is an enterprise of PetroChina, and Jinghong is a private enterprise. Its sales method is better than that of state-owned enterprises. Jinghong mainly does more business in Sinopec, and the sales methods of private enterprises are more flexible. The low price is caused by their different configurations. Moreover, Jinghong is a latecomer and must compete with price advantage. But the top drive is a service product, and the follow-up things will only be known after experience. Jinghong top drive is still double digits. Although it has advantages in Sinopec 1 1, 12, 13, I don't know that Sinopec is brewing reforms and will not implement the contract at all. I suggest to visit the manufacturer on the spot before making a decision. I still suggest Beijing Normal University wait until Jinghong gets the product stabilizer.
