Terminal operators and owners are increasingly looking to increase the size of their quayside container cranes, which presents a series of challenges that must be overcome, such as coping with increased wheel loads, says CP&A.
There is a trend for ports to push their container cranes harder for longer, which can lead to cracks and other fatigue-related issues, says Richard Phillips, mechanical engineer, Casper, Phillips & Associates Inc.
US Crane Consultancy Casper Phillips & Associates (CP&A) was hired by Bubenzer (before it became Dellner Bubenzer) to help it develop a test procedure and observe the testing of the Brake Only Snag System.
A patented tapered dual diameter drum is a key element of a new fully mechanical system that, for container cranes, fulfils both overload safety and operational control over the container trim, list and skew (TLS).
With the US facing labour shortages, supply chain issues and even talk of a recession, several businesses in the overhead crane industry describe what they are doing to help not only their customers, but themselves too.
