Product Introduction

Relying on our exquisite die forging technology, combined with precise machining processes, and implementing a strict quality inspection system, we have the excellent ability to produce a full range of hooks from 2 tons to 2000 tons. As one of the few domestic factories that masters the core technology of manufacturing large-tonnage hooks, we have become a benchmark in the industry.
Our hooks have a wide range of applications. Whether it is ship construction and lifting in large shipyards, material transfer in material factories, or various complex production scenarios, they can be perfectly adapted. What is particularly worth mentioning is that even in the face of extremely harsh environments such as strong corrosion and high temperatures, our hooks can still operate stably and reliably.

At the same time, in order to fully meet the diverse operational needs of customers and improve convenience and safety, we specially customized provide installation options for safety locks. You can flexibly decide whether to install a safety lock based on the characteristics of the actual work scenario and personal operating habits. Not only that, on the basis of the hook blank, we provide precise installation of parts such as beams and caps, which makes it easier for customers to complete the final assembly faster after getting the hook. This thoughtful design greatly simplifies the operation process, making the hook The entire production work is more smooth and efficient, making the operation easy and handy.
