Main Use of Ring Screws

Hanging ring screw This product is widely used in ports, electricity, steel, shipbuilding, petrochemicals, mines, railways, construction, metallurgical chemicals, automobile manufacturing, plastic machinery, industrial control, highways, large-piece transportation, pipeline auxiliary, slope tunnels, well road management protection, maritime rescue, marine engineering, airport construction, bridges, aviation, aerospace, venues and other important industries and infrastructure engineering machinery and equipment.

Hanging ring screw surface treatment: CORRUD-DT, this surface treatment is at least 20 times stronger than the corrosion resistance of ordinary galvanized treatment. The external thread length, the bolt snares with the other parts, and the same quality grade bolt must be used for replacement.

Hanging ring screws are forged as a whole, and by positive fire treatment and removal of oxidizing skin; forgings without burning, crack defects; and ring screws unified through hardness testing, hardness value hrB67 to 95. The strength of the power crown ring screw class is 12. Level 9.

The ring screws must be mounted vertically on the workpiece plane, and the joint surface needs to be flat and the joint steaming tight. The screw must be adjusted to the stretch direction and the screw scares away from contact with the sharp object.

The lifting ring screws pass 2.5 times the test load of the workload and are tested 20,000 fatigue sat esctors at 1.5 times the workload. The ring screws are required to meet or even exceed the ASME B30.26 standard.

Hanging ring screws by alloy steel by high reference German RUD WBG type production, this product is a large number of exports to Europe and the United States, and through the local G80 level standard inspection. Better material, higher than the existing domestic ring screw pull, provides a pull test report.

Hanging ring screws must have a professional to operate, and see the instructions for use, when connected with the sling, should keep the lifting gear and the lifting ring connection area turn freely, there should be professionals to carry out regular safety testing.

Up to 30T of workload and custom-made threads.
