Webbing Sling VS Steel Sling: Which Is Better for Modern Hoisting Operations?
25 Dec

From the relocation of precision instruments in workshops to the loading and unloading of hundred-ton containers at ports; from the lifting of lightweight components for building curtain walls to the transfer of high-temperature steel billets in steel mills---modern lifting scenarios are becoming increasingly diverse, and the requirements for lifting slings have long surpassed the basic need of simply "being able to bear weight." Safety, efficiency, preventing damage to the lifted object, and adaptability to complex environments have become core considerations in selection.

How to Select the Right Wire Rope Slings for Crane Operations?
19 Dec

In crane operations, wire rope slings are critical components connecting the lifting equipment to the load. The proper selection of these slings directly impacts operational safety, efficiency, and equipment lifespan.

How to Choose and Use Lifting Slings

Rigging Hardware Selection and Protection in Offshore Engineering: Don't Let "Small Components" Cripple Large Projects
11 Dec

At offshore wind turbine installation sites, next to the mooring systems of deep-water drilling platforms, and on the decks of subsea pipeline laying vessels, rigging hardware consistently plays a crucial role as a "force transmitter." These seemingly insignificant "steel components" must withstand the immense pressure of hundreds of tons of equipment while resisting the corrosion of seawater and salt spray, and the repeated impact of wind and waves. Post-accident analyses of many offshore engineering incidents reveal that problems often stem from incorrect rigging hardware selection or inadequate protection.

Rigging Use Avoidance Guide: 90% of Safety Problems Stem from These Points
04 Dec

In warehousing and logistics, construction, and machinery manufacturing, rigging serves as the "bridge" connecting lifting equipment and heavy objects, and its safety directly impacts personnel and property safety. However, in actual operations, many people's understanding of rigging remains at the level of "as long as it can lift," neglecting details in key aspects such as selection, operation, and maintenance.
