< PreviousG lobal crane heavyweight Tadano has announced further upgrades to its new AC 5.250-2 mobile crane as part of the fi nal stretch of development for the launch of the crane, which the company showcased in advance at Bauma 2022. With ease of transportation and excellent lifting capacities being the primary development goals that Tadano engineers pursued when designing the new AC 5.250-2, the compnay has now “outfi tted” the machine with a number of additional features that represent a signifi cant upgrade to the crane, particularly in the area of safety. Explaining the upgrades, Tadano clarifi ed that its engineers had already met all their ambitious development goals by the time the AC 5.250- 2 was presented at Bauma in Munich, and the excellent teamwork between the company’s Lauf and Zweibrücken locations played a key role in meeting those goals. Peter Kleinhans, Project Manager at Tadano, explained: “This kind of teamwork enabled us to take full advantage of and combine all the know- The 5-axle AC 5.250-2 is designed to stay within the 12-tonne per axle load limit leaglly allowed on most roads worldwide. TADANO IMPROVES PERFORMANCE, COMFORT AND SAFETY IN NEW AC 5.250-2 MOBILE CRANE New model offers innovative solutions developed to make it the benchmark of its class in as many aspects as possible NEW LAUNCHES 40 | DECEMBER 2023plantmachineryvehicles.comPlant / Machinery / Vehiclesan acoustic warning before reaching obstacles, and will stop the crane itself if there is a risk of collision. The backup assist system is automatically activated the moment the crane’s reverse gear is engaged, making backing up signifi cantly safer – it not only prevents injuries and property damage, but also crane downtimes associated with accidents. The system consists of a technical control system that can be activated with the press of a button and that measures the boom’s defl ection and independently adjusts the lift cylinder in order to compensate for the change in radius caused by the defl ection and to eliminate the risk of swinging. This way, the Lift Adjuster signifi cantly improves safety in the crane’s work environment. For operator comfort, all hydraulic components that emit noise are located away from the superstructure cab, where things are comfortably quiet. Moreover, the spacious design behind both cabs ensures maximum operating comfort and a pleasant work environment. The new AC 5.250-2 is powered by a Mercedes-Benz engine putting out 522hp and maximum torque of 2,600Nm. Meeting Stage V requirements, it is also cost-effective thanks to its Eco Mode, which ensures that the engine always produces the exact amount of power the crane actually needs at any one time, with the IC-1 crane control system taking care of the corresponding calculations. The Tadano AC 5.250-2 has a 70-metre main boom that can be extended by 42 metres with a HAV main boom extension. how and expertise from both our locations.“ According to Tadano, the results are extraordinary, with the corresponding lifting capacities being 10 to 15% higher in many areas - and with certain confi gurations even going all the way up to 30% higher than previous best values in this class. This enables the AC 5.250-2 to easily lead the pack with a lifting capacity of 14.5 tonnes with a 70-metre boom length at a radius of 12 to 24 metres, said Tadano. There crane also offers a lifting capacity of 11 tonnes at a radius of 42 metres with a boom length of 47 metres, which is also at the very top of the capabilities in this class, claims Tadano. EXTENDED SYSTEM LENGTH Another impressive upgrade is in the new crane’s system length: The 70-metre main boom can be extended by a generous 42 metres with a HAV main boom extension, making it possible to reach a system length of 112 metres. Also notable is the fact that all available main boom extensions from 5.8 to 36 metres are self-rigging. The crane can pick up its total counterweight of 80 tonnes in three lifts: 49.6 tonnes with a full 360° radius of up to 6.2 metres followed by two lifts of 15.2 tonnes, with each split into 10 and 5.2 tonnes for mounting on the right and left of the base package. And if necessary, the counterweight can be split into smaller pieces as well, making it possible, for example, to pick up the 5.5-tonne base plate from a distance of up to 20.1 metres across the full radius. “Thanks to the IC-1 Plus crane control system, which comes as standard, the available radius can even be signifi cantly increased at certain slewing angles,” Kleinhans said. In addition, the fact that the counterweight can be split into a large number of elements with none weighing more than 10 tonnes ensures maximum fl exibility for transportation logistics. This means that relatively small trucks can be used for transportation when required by space conditions at a work site. Tadano said its team is also proud of the outstanding transportation confi guration options available for the AC 5.250-2. For instance, it can carry a three-sheave hook block for lifting loads of up to 67.3 tonnes or a 5.8-metre heavy-lift runner on board while remaining within a 12-tonne axle load confi guration – not to mention that the transportation mounts for the HAV extension are included by default in the 12-tonne axle load. Moreover, a payload of several hundred kilograms at the rear end is possible. And with 16-inch steel rims the crane can be used as a taxi crane without a support vehicle while remaining within the legal axle load limit of 12 tonnes. And if the axle load is increased to 16.5 tonnes, it can also carry up to 20 tonnes of its maximum counterweight of 80 tonnes. All these advantages contribute to the new Tadano fi ve-axle unit’s enormous versatility, the manufacturer said. CAMERA-ASSISTED POSITIONING Tadano added that the Surround View camera system, which makes it easier for crane operators to optimally position the crane at work sites, is also optionally available for the AC 5.250-2. This patented system uses six crane cameras to show a computer-assisted diagram of the maximum possible extension lengths for the outriggers at the crane’s current location. “With Tadano Surround View, crane operators can take a look at a display in the cab to know exactly how they need to position the crane at their work site in order to extend all outriggers suffi ciently and ensure that they are using the required counterweight tailswing radius. This eliminates tedious and time-consuming measurements and testing when looking for a location from which to operate the crane, making the latter ready for use faster,” said Kleinhans. Tadano has also added its TailGUARD active backup assist system as an additional technological innovation to maximise safety during travel. This system uses two ultrasonic sensors to monitor the area behind the crane when backing up and works regardless of ambient light conditions. It shows the distance from stationary and moving objects in the monitoring area on the cab’s monitor, plays NEW LAUNCHES Plant / Machinery / Vehiclesplantmachineryvehicles.comDECEMBER 2023 | 41E voQuip, a leading manufacturer of compact crushing and screening equipment and a part of the Terex stable of brands, have announced the launch of the new EvoQuip Falcon 820 Inclined Screen.

The effectiveness of fi eldwork in this industry depends on two critical factors: the equipment and the personnel operating it. These elements are interconnected, with equipment relying on skilled operators, and operators relying on the equipment to perform their tasks. When either of these components is compromised, work in the fi eld suffers. In equipment management, various metrics like downtime, mean distance between failures, and availability are employed to ensure that equipment remains operational and ready to work. However, these metrics often focus solely on equipment performance and don’t account for the wider impact on operations, clients, or the organisation as a whole when breakdowns and downtime occur. As a result, disputes arise, emotions run high, and additional metrics are introduced in an attempt to gain a more comprehensive understanding. Is there an alternative that simplifi es this situation? Is there a metric, well-established and documented in other fi elds that can effectively identify underperforming machinery without complicating business operations further? One such metric, originally used in human resources, may offer a solution: the Bradford Factor. It was designed to quantify the impact of frequent, short-term employee absences on an organisation. The concept is based on the idea that recurrent, brief absences can disrupt a business more than longer, continuous absences. THE BRADFORD FACTOR FORMULA The Bradford Factor formula considers the number of absence instances and the total days absent. The formula is B = S^2 x D, where B represents the Bradford Factor score, S is the number of separate instances within a specifi ed period, and D is the total number of days absent in the same period. Higher Bradford Factor scores suggest more disruptive absence patterns. This metric can be adapted for equipment management. By defi ning “S” as the number of separate downtime events within a specifi ed time frame and “D” as the total downtime days, you can use the Bradford Factor to assess equipment performance. HERE ARE THREE SCENARIOS TO ILLUSTRATE HOW THIS WOULD WORK: • Equipment A experienced one downtime event for a total of 10 days over a 52-week period, The Bradford Factor is a formula that can be used to calculat the cost of downtime to your fl eet’s effi cency and how to remedy it. “In practice, equipment downtime often occurs on project sites where operational effi ciency is critical. When equipment is down, it leads to production delays, schedule disruptions, increased costs, reduced profi tability, and downstream impacts on return on investment” TIPS & KNOWLEDGE Plant / Machinery / Vehiclesplantmachineryvehicles.comDECEMBER 2023 | 47resulting in a Bradford Factor of 10: (1 x 1) x 10. • Equipment B had two downtime events, each lasting five days, over a 52-week period, resulting in a Bradford Factor of 40: (2 x 2) x 10. • Equipment C had 10 downtime events, each lasting one day, over a 52-week period, resulting in a Bradford Factor of 1,000: (10 x 10) x 10. These scenarios demonstrate that equipment with shorter, more frequent downtime events yields higher Bradford Factor scores, indicating a more significant negative impact on the organization. In practice, equipment downtime often occurs on project sites where operational efficiency is critical. When equipment is down, it leads to production delays, schedule disruptions, increased costs, reduced profitability, and downstream impacts on return on investment. APPLYING BRADFORD FACTOR TO MACHINERY MANAGEMENT To apply the Bradford Factor to equipment management, you can compile data for your equipment fleet. The table below lists 10 dozers, detailing the number of downtime events (S) and downtime days (D) for each unit. The average days down as well as the Bradford Factor are calculated and placed in the columns to the right. Unit D6007 had the highest number of down days and the highest average days down, while Unit D6003 had the second-highest average Using the Bradford Factor, fl eet owners can identify the particualr pieces of equipment that cost the most to the fl eet in terms of downtime. The Bradford Factor allows isolation of units that require the most extensive maintenance jobs so that they become productive again. TIPS & KNOWLEDGE 48 | DECEMBER 2023plantmachineryvehicles.comPlant / Machinery / Vehiclestheir average down days are some of the lowest in the group. The magnitude of the scores suggest that it was harder for the business to plan around the downtime of these units. When the Bradford Factor is employed, you can be absent frequently but not for long periods, and you can be absent for long periods but not frequently. A machine can be down frequently but not for long periods, or a machine can be down for long periods but not frequently. Notably, units with infrequent but longer- term downtime events may have lower Bradford Factor scores, as it is easier for the business to plan around these instances. In contrast, units with frequent and shorter downtime events may have higher Bradford Factor scores, indicating that it was more challenging to adapt to their downtime. A SYSTEMATIC APPROACH Using the Bradford Factor in equipment management provides a systematic approach to identifying underperforming equipment and aids decision-making regarding maintenance priorities. The concept of applying the Bradford Factor to equipment management emerged during a seminar in Canada, where it was used to assess machine performance and identify problematic equipment. By aligning readily available data with the Bradford Factor (S being the number of repair work orders and D being the mechanic hours spent), the results closely matched the opinions of those who worked with the equipment daily. This adaptation of the Bradford Factor offers a quantitative way to pinpoint underperforming equipment, aligning with intuitive assessments of their performance. As organizations strive for operational excellence, the Bradford Factor provides a concise and effective means to enhance maintenance decision-making. days down. But neither Unit D6007 nor D6003 are in the top five of the Bradford Factor. This is because both units had infrequent and longer-term down periods, so their Bradford Factors were much lower than units that had more frequent and shorter down events. Although both of these units certainly have issues that need to be addressed, the results suggest that it was easier for the business to plan around the downtime of these two units. Units D6005, D6009, and D6010 have the highest Bradford Factor scores even though The Bradford Factor is derived from Human Resource Management practices of identifying frequent short-term employee absence. “Is there a metric, well-established and documented in other fi elds that can effectively identify underperforming machinery without complicating business operations further?
