Airpes Presents Eagle Black Box Crane Monitoring System
> Barcelona, Spain-based Airpes has launched a black box product—the Eagle—that monitors and logs the hoist, trolley and bridge movements of high duty cycle overhead cranes and hoists to ensure safe lifting and use within intended parameters. Airpes, a weighing systems and lifting
equipment specialist, is presenting the Eagle system as part of its AL-series of overload devices, but it sits at the top of the portfolio, including a multi-hoist overload protector, multi anti-collision crane system, and full connection with a black box app, for download on a laptop or smartphone. The system is available with a customized black box for hoist manufacturers’ volume production. The Eagle can be installed in the control
panel, usually located on the trolley or bridge, of a new electric overhead travelling (EOT) crane, or retrofitted. It is manufactured to M8 standards, a duty rating covering 20 or more lifts per hour at or near a crane’s rated capacity. This equates broadly to U.S.-based norms, Crane Manufacturers Association of America (CMAA) E / F or Hoist Manufacturers Institute (HMI) H5+ duty. It primarily suits the Eagle to installation
on cranes in medium to heavy-duty environments such as steel mills, coil processing plants, steel service centers, precast cement factories, metals production, shipyards and ports. However, it is also suitable for lifting applications where the duty cycle might be much lower, but where the load is extremely fragile and / or expensive, as is commonplace in the aerospace and nuclear industries, for example. Tad Dunville, general manager at Airpes
North America, said: “It is a multifaceted product with many features, but a holistic benefit is the input and output data it provides in relation to SWP [safe working period], which is the legally-mandated maximum run time before overhaul is required. Starts, cycle times, overloads, etc. are all calculated to provide a comprehensive overview to increase productivity and

throughput for cycle-conscious customers.” While serving as an SWP controller to
FEM 9.755, the Eagle can control up to four hoists and features a load limiter with 10 configurable outputs on 30 limits. It also covers 10 combinations of the sum of loads. Data captured includes number of overloads; number of weight cycling and accumulated total weight; register of the last 1,000 overloads with maximum weight, start date, time and duration; register of the last 10 weighings with maximum weight, start date and time; and estimates of the working group with number of cycles and maximum weight over time. Dunville said: “In simple terms, the Eagle
limits the hoist from picking up too much. But it can also control no-fly zones, where perhaps a section of runway isn’t rated as high as another or a customer doesn’t want a load carried near a particular machine. For example, if a crane loaded with a coil raised all the way up extends 10 ft. below the girder but the empty hoist only extends 5 ft. below the girder, that difference may cause contact with expensive plant fixtures and machinery. We can limit the crane to only travel in that area when unloaded or to completely nil travel in that area.” He added: “We typically work with
crane manufacturing and service companies or hoist OEMs [original equipment manufacturers], but we will work with end users upon request. Importantly, we are crane people only selling crane solutions; we don’t do other applications. We manufacture and assemble everything at our facility and test it as a system to ensure those in the field don’t have to do on-the-job integration. When there are problems, people can talk to experienced crane people at our offices in Spanish or English.” y
Trand chooses Liebherr LG 1750 for wind turbine project in West Texas
> A Liebherr LG 1750 provided the primary lifting power for Trand, Inc., during a nearly two week long project in May. The company provided crane services for a main shaft exchange on a wind turbine with a nearly 400- foot hub height in the Lubbock, Texas area. Based in Pratt, Kansas, Trand took
delivery of the first LG 1750 in the US in March. The LG 1750 is an 850 US ton-class eight axle, lattice boom mobile crane with the mobility of a drivable carrier and the lifting capacity of a crawler crane. It has a

633-foot maximum hoist height, six winches and variable boom systems. Among other items, the crane handled a gearbox assembly and its heaviest lift was 162,000 pounds. Under the leadership of Trand
President Terry D. Arnett, Vice President of Operations Andrea D. Arnett, crane operator Ken Cornelson, Jr. and rigger and oiler Patrick Petersen, all of the LG 1750’s standard features, combined with some additional equipment, helped the project get done safely, efficiently and on schedule. “One challenge we faced during the planning
of this job was that the allowable ground bearing pressure was very low,” said Andrea Arnett. “At the time of the crane purchase, we also purchased eight steel mats to help spread the pressure over a larger area and minimize the pressure per square foot to the ground. The steel mats were essential for this job.” The strength of the LG 1750 on this job
was its lifting capacity and luffing abilities. Trand also purchased a 344-foot luffing jib with the crane. “The luffer was essential for this job,” Arnett said. “We originally did not plan to use it, but the blades on this rotor had a 40-foot pre-bend and would likely have hit the boom using the original configuration.” The crane was sitting at a 110-foot radius and was able to easily remove and replace the rotor. This crane is also stabilized on an
outrigger system which makes it safer than other cranes of similar size and capacity. Fast mobilization and easy assembly and disassembly are benefits Trand appreciates. Including the LG 1750, Trand owns four
Liebherr cranes – two LTM 1750-9.1 mobile cranes and an LTM 1300-6.2. “We feel the LG 1750 is a great addition to our fleet to service the larger turbines that the current fleet cannot handle. We also plan to use it for plant work,” said Arnett. Trand’s overall fleet consists of 11 mobile
cranes. This positions the company to serve the wind power industry, which is continually moving toward larger towers and heavier components. Founded in 1990, Trand specializes in wind industry, refinery and gas plant projects and employs 22 people. “The courtesy that Liebherr has shown
us and our employees is above and beyond,” Arnett said. “With this being a new crane in the United States, there were many obstacles we had to overcome to make it work for our company, and Liebherr has gone the extra mile to make those adjustments. The gestures they have shown us make you feel more confident in your purchase and make you realize what an honor it is to own a Liebherr crane.”
