helps prevent load swing caused by load misalignment when the rope and hook are not vertical. As an added layer of protection, Intelli-Lift also detects snagged conditions that can occur along the travel path, or when moving hooks, slings, and rigging to the next lift, and stops all motions. Swinging loads are not only dangerous


for operators; they can damage equipment, resulting in costly repairs and downtime. To reduce these risks, Intelli-Lift alerts operators with a visible and audible warning before a dangerous load misalignment or snag condition occurs. Using sensors and a status control enclosure, the system activates directional lights and a programmable warning horn if it detects a side pull or off-center pick. Intelli-Lift will then assist operators, through manual or automatic adjustment, to center the bridge and trolley over the load before it is hoisted. “Suitable for new installations or retrofit


applications, Intelli-Lift enables precise load control, reduces stress on equipment, and offers quick, easy installation,” said Peter Stipan, Global Director, Automation Division. “Available in two configurations, Detection and Prevention, Intelli-Lift provides varying levels of control depending on application needs.” In the Detection System, the status


control enclosure provides notification of a misalignment or snag and allows the operator to manually correct the load position. The Prevention System offers two types of positional correction: Manual and Auto. In either Manual or Auto Correction, the load cannot be adjusted until the hoist motion is stopped. While using Manual Correction, an operator can use a Magnetek pendant or radio remote control to manually realign the load. In the Auto Correction System, software built into the Intelli-Lift System automatically re-centers the hoist above the load by moving the bridge and trolley. Intelli-Protect™ System No Fly-Zone


Technology Another product in the Intelli-Crane


family is the Magnetek-brand Intelli- Protect™ System. Intelli-Protect allows you to designate no-fly zones, or locations where a crane is programmed to slow down or stop, using motion control products such as variable frequency drives, radio remote controls, limit switches, and sensors. These versatile systems — ranging from simple configurations to the more complex — limit the risk of collisions, increase safety

RSS Removes Railway Footbridge Hit by Lorry


> Rope and Sling Specialists Ltd. (RSS) provided rigging gear to Quattro Plant Ltd. as an adapted rail crane lifted a 20t railway bridge that was knocked off its foundations by a heavy goods vehicle in South Wales recently. Quattro is a specialist provider of hire


solutions to the railway sector and boasts a varied fleet of road rail vehicles. In this instance it utilized its 55t capacity Demag AC55 Rail (City) Crane to complete urgent removal of the approx. 24m-long footbridge that had fallen awkwardly, with one section trapped between a tree and an abutment wall. Quattro contracted RSS to supply


rigging gear to work beneath the hook of the three-axle, telescopic boom, all-terrain crane. It delivered three spreader beams that were used in a one-over-two configuration; a MOD50 was used at 10m in length at the top, while two MOD24 beams were used at 3m in length underneath. The MOD50 can be used up to 50t at 8m and up to 13m at a lower capacity; the MOD24, meanwhile, can be used up to 24t at 5m and up to 8m at a lower capacity. All were supplied with top and bottom shackles. RSS also supplied a pair of 30t capacity


roundslings with an effective working length of 10m that were rigged from the crane’s hook down to the top beam. Four 10t capacity roundslings with an effective working length of 4m connected that beam to its lower counterparts. Completing the rig were four 12t capacity, 6m-long collar chains and shorteners; and four 25t capacity alloy bow shackles. Gary Worsley, site manager / appointed


person at Quattro, said: “The bridge was cut into sections prior to removal because of the way it had fallen, and each load was cradled as we lifted the pieces. We lowered them onto a road rail vehicle and trailers for

transportation by rail to a site compound, where they were to be off-loaded and cut up into smaller pieces as scrap. The rig was the most efficient given the loads, based on structural reports issued by our client; centre of gravity wasn’t a complication in this case.” Worsley explained that Quattro took a


phone call at 9:30am and was onsite with the crane and lifting gear by 6:30pm on the same day, by which point all trains had been suspended and police had cordoned off the road and a site compound was being completed. He added that the structure was unsafe and, inevitably, access was tightly restricted. Stephen Littler, regional manager,


Warrington, at RSS, said: “The footbridge removal was another example of us sourcing and mobilizing a below-the-hook rig for use in an emergency situation. Same-day delivery is imperative in such situations; without healthy stock levels at each of our regional depots, that kind of service would be impossible to provide—to customers like Quattro or others who fulfill this type of contract. In addition to two AC55s, Quattro owns


five 40t capacity Demag AC40 City Cranes, all converted to travel on rail infrastructure. Worsley said: “These are the only converted cranes in the UK—possibly Europe.” Worsley and RSS both expect to be involved in installation of a replacement footbridge. y


RSS Expands JDN Range with Profi Air Hoist


> Rope and Sling Specialists Ltd. (RSS) has secured a nationwide (UK) distributor and service partnership for JD Neuhaus’s (JDN) Profi air hoist range, available in capacities from 250kg up to 100t. The Profi air hoist range, offering air


pressure in four or six bar, is an explosion- protected series, suited to heavy-duty industrial use. It is available with various control options depending on the application and is especially suited for use in hazardous areas. RSS first teamed up with JDN in mid-


2019 and has since offered its pneumatic and hydraulic hoists, crane systems, and components, manufactured at headquarters in Germany, principally for use in extreme environments. It had also added to the portfolio a product for lifting in areas that require ultra-cleanliness and hygiene, such as the food and beverage sector. Steve Hutin, managing director at RSS, said: “It was always our intent to expand our
