Answering your wire rope questions 

Rope analysis graphicThe Konecranes Rope Analysis is designed to provide expert consultation to answer your wire-rope and rope-reeving questions. The analysis targets individual concerns such as rope selection, rope life, component failures, unexpected rope behavior, accident investigation or improvement opportunities, including recommendations on extending rope and component life. 

Using proprietary 3D modeling and calculation tools, we provide an engineering assessment, calculation and inspection of your ropes and reeving components. The rope life calculation is based on the EN 13001-3-2:2014 standard. 


Rope life estimate and recommendations 

We provide expert consultation and can give you a calculated estimate of rope life, recommendations for rope selection or rope reeving geometry improvement to target a variety of issues. The Rope Analysis can also be used to investigate a rope failure.

A deep look at the condition of your crane hook 

Hook analysisThe crane hook and bottom block components are stressed during each hoisting cycle. Hooks can fail due to cumulative fatigue. These failures often start as a fatigue crack in the hook shank. Heavy process-duty applications, changes in application and the use of below-the-hook lifting devices can all contribute to cumulative fatigue. 


Calculating the remaining fatigue life of your hook 

The Konecranes Hook Analysis utilizes visual and NDT inspections combined with fatigue calculations of the hook/shank and critical components of the bottom block. We're able to calculate the remaining fatigue life of your crane hook by reviewing the operating history of the crane and using that in conjunction with the reeving system dimensions.  

Our expert consultation on hook life, condition and safety can be helpful in planning, troubleshooting, and accident investigation. Konecranes uses the most current hook standard and analysis methods to estimate hook life. 

Recommendations are provided for the continued use of the hook along with a detailed continuing inspection plan.
