Busan Port Authority Develops Patented Clip Technology for Harbor Crane Maintenance... Ensures Safety Without Separate Construction

[Asia Economy Yeongnam Reporting Headquarters Reporter Hwang Du-yeol] Busan Port Authority (BPA) has developed a patented technology for a ‘height-adjustable replaceable clip for port cranes’ rails’ to enable efficient maintenance of crane rails within the port.

The clip for port cranes is a device used to secure crane rails and is installed to control rail vibrations and pressure.

Existing clips for port cranes have an integrated rubber elastic device that directly presses the rail, so when the rubber elastic device wears out, the entire clip had to be replaced.

When rail subsidence occurs due to pad wear under the rail, a gap also forms between the rubber elastic device and the rail.

The replaceable clip developed by BPA allows only the rubber part to be replaced when the rubber elastic device wears out, resulting in maintenance cost savings of over 80% in the future.

When a gap occurs between the rail and the rubber elastic device, the insertion of a spacer (Plate type) can secure the rail’s safety without additional construction work.

BPA proceeded with the development of the height-adjustable replaceable clip until March 2021, followed by prototype production and pilot introduction, and completed patent registration in June this year.

The patented product is planned to be applied during this year’s maintenance work.

It is expected that applying this technology in port sites will shorten maintenance work periods and reduce construction costs.

Kang Jun-seok, President of BPA, said, “We will continue to strive for technological development to increase the efficiency of maintenance work and realize a safe Busan Port.”
