Example 5: Gear for Cranes – Worm Shafts
Wen-Hsiang machines high-precision worm shafts with heat treatment. The crane gears must be of high precision to prevent the crane from slipping and ensure that the crane endures the repeating work of pulling or pushing away objects. Wen-Hsiang's worm shafts are reliable and durable. They ensure that cranes can withstand intense work conditions and run smoothly. Our quality control ensures that our worm shafts are optimized for your cranes.
