The company, a specialist in load testing, completed an annual inspection of the crane, which has a safe working load of 11.6t at a radius of 6.27m and 5.3t at 12.04m. It was manufactured by Italy’s Heila, a provider of custom-built marine and offshore lifting equipment.
PT Xtra, which services oil and gas, construction and marine customers, stocks load cells ranging in capacity from 5t to 200t but in this case it chose Straightpoint’s most popular product, the Radiolink plus.
Commonly used in conjunction with water bags, the load cell is capable of both weighing and dynamic load monitoring.
PT Xtra completes up to four load tests every month, many of which represent repeat business from regular customers. It has recently employed Straightpoint’s force measurement, load monitoring and suspended weighing load cell equipment on a myriad of applications, including load tests on an overhead crane in a Batam warehouse and a davit crane used for releasing rescue boats.
“The latest Radiolink plus wireless dynamometer is constructed of aircraft grade aluminium and features an advanced internal design structure that not only provides the product with great strength to weight ratio, but also facilitates the use of a separate internal sealed enclosure,” Straightpoint said.
Heru Gunawan, director at PT Xtra, said the scope of work from Jan de Nul included completion of a load test on a second similar crane aboard a separate vessel. Again, the Radiolink plus was used.
