Dynamic Rigging Hire has recently completed a load test on a 130-ton overhead gantry crane in New South Wales, Australia, collaborating with a crane manufacturer and its client.
The company conducted the test to 110% of the crane’s rated capacity, reaching 143 tons.
It has performed the load test using a combination of steel test weights and water load bags.
The limited headroom posed a challenge, preventing the use of larger water load bags or a second tier suspended below, a method often employed for outdoor or ship-based cranes.
To address this, Dynamic Rigging Hire utilised steel test weights and four 35-ton water bags, achieving the necessary mass for the dynamic testing parameters.
The crane underwent dynamic testing to 130 tons before being subjected to a static test at 143 tons, representing 110% of its rated capacity.
Calibrated load cells were used throughout the process to ensure accurate measurement of the load mass.
All rigging and load test equipment were pre-inspected and certified to guarantee safety and precision.
Dynamic Rigging Hire, in a LinkedIn post, said: “Load testing new crane installations is a vital part of the commissioning process. Taking cranes and their supporting structures to “proof load” conditions is a unique and essential procedure.
“At Dynamic Rigging Hire, we have been providing our expertise to the crane service sector for many years with our comprehensive crane load testing services.”
Established in 2009, Dynamic Rigging Hire offers comprehensive proof load testing services for various lifting equipment across southeast Australia.
The company provides services for land-based cranes, maritime applications, and weighing large structures.
As the southeast Australian agent for the Seaflex product, Dynamic Rigging Hire uses water-filled bags for maritime load testing, offering a cost-effective alternative to steel or concrete weights.
