BELOW THE HOOK Ӏ SECTOR REPORT
called Below the Hook rather
than own them. “Hiring gives us much more flexibility,” added Nolan. “Below the Hook take care of all the testing and transportation to and from site. It means we can fully focus on the lifting operations as they handle everything else.”
IN THE FRAME Spreader frames are another option to add control and predictability to lifting operations. Modulift has just redeveloped its CMOD Modular Spreader Frame which now comes with an updated Corner Unit design which, it says, is up to 40% lighter while also being stronger than the original version. In addition, Modulift says the new design is up to 50% less expensive, too. The new CMOD Corner Unit was designed using advanced ANSYS engineering software packages. Modulift’s in-house engineers conducted a non-linear contact stress analysis on the corner unit bow simulating a full design load applied through the shackle. As a result, the new
Angus Jamieson, MD at Torquer, demonstrating the principle of its HALO lifting frame
and improved corner units are designed to minimise contact stresses between the top shackle bow and corner unit centre plate, providing optimal performance and durability. New CMOD Corner Units can
be combined with existing Modulift Struts and T-Pieces to create 4-, 6- or 8-point lifting frames. Modulift’s CMOD range
features eight different sizes to suit individual lifting needs, starting with the CMOD 6, capable of
A show of strength
Carl Collins, marketing manager at load cell specialist Dynamic Load Monitoring (DLM) demonstrated the company’s Standard Tensile Link at Vertikal Days trade show in the UK, along with the company's other products. “The tensile link load cell can go below the hook of a crane to measure tensile strength,” says Collins. “Our Tensile Links can be used to weigh anything from one tonne to 500 tonnes – so things like water bags and concrete. It’s rigged with shackles on either. One of its key benefi ts is that it’s a bit more accurate than our shackle load cells – although the shackles have less height for rigging, so which to use really depends on the user’s requirements.” The tensile link is made of light weight aerospace grade aluminium and can be branded for rental crane or rigging companies, such as DLM has done for RSS. The tensile link has a 800 metre range and the handheld
display is built by DLM to be interference-free for use in environments such as ports. It also provides a ‘rolling average’ feature for dynamic
lifts where rapid peaks and troughs may otherwise make obtaining a reading impossible.
