Lifting Gear Inspection and Discard Criteria

Lifting Gear Inspection and Discard Criteria: Complete Safety Guide for Crane Hooks, Shackles, Chains and Wire Ropes   Lifting operations are critical processes across industries such as construction, heavy manufacturing, offshore engineering, and port logistics. As the direct load-bearing interface between lifting equipment and loads, lifting gear plays a decisive role in operational safety. From crane hooks and shackles to welded chains, synthetic webbing slings, and steel wire ropes, improper selection, inadequate inspection, or delayed discard may lead to structural failure and serious accidents. International standards such as ISO lifting regulations and ASME rigging standards, together with Chinese GB standards, clearly define inspection and discard requirements. This guide provides a […]

How to Select the Right Crane Drum for Maximum Service Life

Selecting the correct crane drum is critical for lifting safety, wire rope life, and long-term operating cost. Whether you are designing an overhead crane, gantry crane, or hoist system, the drum directly affects fatigue performance and structural reliability. At Hanko Heavy Industry, we manufacture and export crane hoist drums for heavy-duty industrial applications worldwide. Based on real project experience, this guide explains how to choose the right wire rope drum step by step. Why Crane Drum Selection Directly Affects Safety A crane drum is not simply a rope storage component. It is a load-bearing mechanical part subjected to repeated bending stress from the wire rope. If the drum diameter, groove […]
