BELOW THE HOOK Ӏ SECTOR REPORT
a maximum WLL of 8t and an assembled span range between 0.5m and 2.5m, all the way up to the CMOD 250, with a maximum WLL of 300t and a span range between 2m and 20m.
ORIENTATION DAY Another area of below the hook equipment designed to provide greater control when lifting loads is load orientation devices – an niche that has developed quickly over recent years with systems from Verton, Roborigger, Vita Industrial, and Torquer utilising different techniques to achieve laod control. The system Inverness,
Scotland-headquartered Torquer has developed is called the Halo (Hands-free Autonomous Load Orientation), the latest iteration of which the company showcased at the recent Vertikal Days trade show in the UK. The system is designed to keep workers away from moving loads by giving them remote control over the crane load rotation. Torquer’s solution is unique in that it uses accelerating water to generate torque. This, the company says, prevents the danger
and energy usage associated with the high-speed rotating steel discs of gyroscopes.
It is available as a lifting frame or as an independent device that fits to any lifting beam. Torquer managing director Angus Jamieson says the company is continually looking to evolve the Halo system and make any improvements it can. “We’ve seen some demand
for our lifting frame to have more power but without extra weight,” he said at Vertikal Days. “We found that the bigger we make the [lifting frame’s] circuit you actually get more power from the same amount of water. “We’ve found that by doubling the lifting frame’s dimensions you can get up to eight times more turning power. We’ve just sent one of these bigger units out to Abu Dhabi, UAE, where it will be used for lifting pipes off a ship.” On the Halo that fits lifting
beams Torquer has also been lightening the system by swapping out its steel tanks for polyethylene tanks. “These are about 500kg lighter each,” highlights Jamieson “By reducing its weight the reach it can be used at on, say, a tower
Vita Industrial
launched its VLN load control device to the UK and Europe at Vertikal Days
crane, is increased. It's all about trying to keep the weight down.” Load orientation device
manufacturer Vita Industrial was also at Vertikal Days, on Wolffkran’s stand. It used the event to launch its Vita Load Navigator (VLN) to customers in the UK and Europe.
The Vita Load Navigator uses intelligent aviation sensors to detect load position, windspeed, and more than 1,000 other data points per second. High- powered air thrusters adjust loads within milliseconds with up to 1° accuracy, the company claims. The unit is controlled via remote for precision lifting. Vita Industrial has also been
working with DPR Construction, a US-based general contractor with projects worldwide. In recent months, DPR and Vita have partnered in a pilot programme of Vita’s hardware and software

Heat resistant soft sling
Lift-Tex Heavy Lift Slings is a heavy lift sling manufacturer based in the Netherlands. It specialises in heavy lift HMPE round slings (such as Dyneema) for heavy lift projects worldwide. The company has launched Inferno, a heat resistant soft sling that lifts loads in temperatures up to 200°C. It is made of 100% aramid and comes in yellow or black. Its knitted jacket is reparable for a sustainable solution. It is available from 0,5m to 65m.
