Ocean engineering

In the manufacturing industry of marine engineering transmission equipment, CQ-Gearbox has developed multiple types of lifting gear drive device. The products have been widely used. The reduction ratio of a single lifting gearbox is large. By the reduction of multi-stage parallel transmission and multi-stage planetary and loading shunt, the reduction ratio can be over 6000:1, and the output speed can be less than 1 r/min. The output gear adopts the method of large modulus, big pressure angle, and small number of teeth. The material is high-strength alloy steel, which can effectively ensure the load-carrying capacity of the gear. The lifting capacity of a single output gear can reach450 tons.

It is classified according to the operating water depth and the rated lifting capacity of a single gearbox. 50 tons. Operating water depth covers from 200 feet to 550 feet; the rated lifting force of a single unit ranges from 50T to 450T.
