In favor of ideal investment condition necessary for heavy duty equipment manufacturing, most of global heavy industrial giants have set up their manufacturing or supplying base in China, especially in littoral areas, where are also the main areas that Openex provide custom metalworking service from. As an example, the industry of container handling equipment, such as Ship to Shore Container Gantry Crane (STS); Rubber Tyred Gantry Crane (RTG); Rail Mounted Yard Gantry Crane (RMG); Loaded Container Handling Reach Stacker (RS) and Empty Container Handling Liftruck (ECHL), the top 10 makers worldwide including Chinese native companies and international companies in China export every year large portion of equipment to worldwide ports. Openex has the capability to help these crane makers get supply of heavy duty metal components with good price, high quality and just-in-time delivery.
We custom make legs, cross beams for Rubber Tyred Gantry Crane, body frame for reach stackers, and also other necessary metal parts and components. The processes include cutting, bending, welding, turning, milling, boring, and assembling, among which the welding quality is important, therefore MT and UT are widely used to make sure the quality of the welding on structural components.
We also produce steel shafts over 3meters, bronze bush with inner diameter over 540mm and wall thickness over 10mm, which are required to have relatively high precision for easy assembling. The two holes for the shaft to go through are required to have high concentricity，we machined the pair of holes with double sided boring machine.
The parts, components we produced for gantry crane are also exported to Australia directly. The quality feedback is good, so we are referred by our customer to his friend for other fabrication business.
