Modulift Upgrades Compression Test Rig to 1,650t Capacity
> Below-the-hook equipment manufacturer Modulift has upgraded its compression test rig (known as CTR1), adding 50% additional capacity to the now 1,650t machine. This is the second time Modulift has
upgraded the rig it originally manufactured in 2003 for testing 600t capacity spreader beams to a proof load of 660t. In 2012 it upgraded
CTR1 so 1,000t beams could be tested to 1,100t, while 1,500t beams can now be tested to the new capacity following the latest three- month retrofit. This was by far the most extensive
engineering that the rig has been subjected to in its lifetime. Sue Spencer, technical director, explained that the first upgrade was “not particularly major”, recollecting the replacement of a small number of components and strengthening of others. However, the latest project involved approximately 60% of the rig being replaced with new components. Spencer said: “We have been outspoken of
late about industry driving demand for larger capacity beams so it made sense to invest in the upgrade of our flagship test rig, which has been at the heart of the company for 14 years. Not only is it now one of the largest rigs of this type in the country, it is custom-designed for our specifications and thus makes an incalculable contribution to our manufacturing processes.” Every Modulift modular spreader beam
consists of a pair of end units and a pair of drop links with interchangeable struts that can be bolted into the assembly between the end units
to either lengthen or shorten the beam. Spencer explained that the unique design means they are essentially “pin-ended struts” and the entire load is transferred through the spreader beam as a pure axial compression load. The main rails of the rig are therefore in tension when the spreader beam is under test. She said: “We have squeezed as much
capacity out of the main rails of the rig as possible without having to replace the whole machine. We have increased the width and height of the rig so larger diameter spreaders can be tested. If there is demand in future to go even bigger we will consider it, but that would certainly mean replacing the rails.” Upon completion of a beam’s
manufacturing process, it is placed into the test rig and pinned into place at each end. A compression load is then applied to the pin at one end, whilst supporting the pin at the other. The drop links are then tensile tested separately in their own test rig, also located at Modulift’s facility. The on-site tensile rig can test drop links up to 50t capacity, while independent test houses have conducted tests on Modulift’s behalf up to 825t.
