Ease of transportation combined with strong lifting capacities \u2013 this was the primary development goal that the engineers at Tadano pursued when designing the new AC 5.250-2, which the company showcased in advance at bauma 2022. Now, as part of the final stretch of development for the crane\u2019s launch, Tadano has added a number of additional features that represent a significant upgrade to the AC 5.250-2, particularly in the area of safety.<\/strong><\/p>\n\n\n\n

Just to make it clear, however, the engineers at Tadano had already met all their ambitious development goals by the time the AC 5.250-2 was presented in Munich, and the excellent teamwork between the Lauf and Zweibr\u00fccken locations played a key role in that. \u201cThis kind of teamwork enabled us to take full advantage of and combine all the know-how and expertise from both our locations,\u201d explains Project Manager Peter Kleinhans. And the extraordinary results can be seen, for example, in the improved lifting capacities, which are 10 to 15 percent higher in many areas, and in certain configurations can even go all the way up to 30 percent higher. This enables the AC 5.250-2 to easily lead the pack with a lifting capacity of 16 tons with a 230 ft. boom length at a radius of 39 to 79 ft. There is also its lifting capacity of 12 tons at a radius of 138 ft. with a boom length of 154 ft., which is also at the very top of its class \u2013 to name just two examples. This impressive run is continued by the new crane\u2019s system length: The 230 ft. main boom can be extended by 138 ft. with a HAV main boom extension, making it possible to reach a system length of 367 ft. Also notable: All available main boom extensions from 19 ft. to 118 ft. are self-rigging, with no assist crane required.<\/p>\n\n\n\n

A sophisticated counterweight concept<\/strong><\/strong><\/p>\n\n\n\n

The crane can self-assemble its total counterweight of 88 tons in three lifts: 54.7 tons with a full 360\u00b0 radius of up to 20.3 ft. followed by two lifts of 16.7 tons, with each split into 11 and 5.7 tons for mounting on the right and left sides of the base package. And if necessary, the counterweight can be split into smaller pieces as well, making it possible to pick up the 6-ton base plate from a distance of up to 66 ft.  across the full radius. \u201cThanks to the IC-1 Plus crane control system, which comes as standard, the available radius can even be significantly increased at certain slewing angles,\u201d Peter Kleinhans underscores. In addition, the fact that the counterweight can be split into a large number of elements with none weighing more than 11 tons (10 metric tons) ensures maximum flexibility for transportation logistics. This increases the transportation options and also means that relatively small trucks can be used when required by space conditions at a work site. <\/p>\n\n\n\n

Right on board: the latest Tadano technological features<\/strong><\/strong><\/p>\n\n\n\n

Tadano designed the AC 5.250-2 to come with comprehensive equipment as standard right out of the gate, not to mention that all new cranes in the Tadano AC family will benefit from the same equipment, with one example being the innovative IC\u20111 Plus crane control system<\/strong>. This state-of-the-art touchscreen-controlled system determines the crane\u2019s maximum lifting capacity in real time for every boom position as a function of the superstructure\u2019s slewing angle. As a result, the crane is always able to take advantage of the maximum lifting capacity available to it \u2013 especially during lifts over the outriggers. In other words, this feature provides the greatest support when it comes to lifts in which the outriggers are not fully extended and the counterweight is reduced. The AC 5.250-2 benefits from this tremendously, as its outriggers can be extended asymmetrically to 0, 25, 50, 75, and 100 percent positions.<\/p>\n\n\n\n

In addition, the one-of-a-kind Surround View<\/strong> camera system, which both increases safety while driving and also makes it easier for crane operators to optimally position the crane at work sites, is also optionally available for the Tadano 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\u2019s current location. \u201cWith 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 sufficiently and ensure that they are using the required counterweight tail swing 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,\u201d explains Peter Kleinhans. The system also provides assistance on the way to the work site by making it easier for crane operators to notice pedestrians and cyclists when turning.<\/p>\n\n\n\n

Lift Adjuster \u2013 improved safety during travel and operation<\/strong><\/p>\n\n\n\n

In the future, the AC 5.250-2 will additionally come with one more important safety feature: The Lift Adjuster<\/strong>, which is a revolutionary one-of-a-kind lift assist system and is scheduled to become available for the crane in the coming year. The system consists of a technical control module that can be activated with the press of a button and that measures the boom\u2019s deflection and independently adjusts the lift cylinder in order to compensate for the change in radius caused by the aforementioned deflection and to eliminate the risk of swinging. This way, the Lift Adjuster significantly improves safety in the crane\u2019s work environment.<\/p>\n\n\n\n

A comfortable and safe workstation<\/strong><\/strong><\/p>\n\n\n\n

When developing the AC 5.250-2, the team at Tadano also made sure to attach special importance to the needs of crane operators. Accordingly, 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. As for safety, the intelligently positioned access points, attachment points for operators\u2019 personal safety equipment, and a step that can be extended from the carrier to make it safe and comfortable to enter and exit the superstructure cab all contribute. Moreover, the hill start assist system, which comes as standard, ensures stress-free travel operation when driving up and maneuvering on uphill slopes.<\/p>\n\n\n\n

Environmentally friendly operation<\/strong><\/strong><\/p>\n\n\n\n

Finally, the new AC 5.250-2 also makes a compelling case when it comes to its engine, a state-of-the-art Mercedes-Benz unit with an output of 522 hp and a maximum torque of 1917 ft-lb.  that provides solid propulsion and powerful lifting capacities. And it goes without saying that the HVO-compatible diesel engine meets the latest engine emissions requirements. In addition, it is particularly cost-effective thanks to its Eco Mode, which ensures that the engine always outputs the exact amount of power that the crane actually needs at any time, with the IC-1 crane control system taking care of the corresponding calculations. In addition, the crane also has a fuel-saving start-stop feature on board, with the system turning off the crane engine at the press of a button but without deactivating the control software.<\/p>\n\n\n\n

The bottom line<\/strong><\/strong><\/p>\n\n\n\n

The Tadano AC 5.250-2 tech demo immediately won over a large number of experts and other visitors back when it was revealed in Germany at bauma 2022, which should come as no surprise, as the state-of-the-art five-axle crane raises the bar in a large number of areas. This provides the crane with tremendous versatility, which combined with an enormous reach and large lifting capacities makes the unit perfect for erecting tower cranes and for construction projects of all types.<\/p>\n\n\n\n

Just to make it clear, however: The engineers at Tadano had already met all their ambitious development goals by the time the AC 5.250-2 was presented in Munich, and the excellent teamwork between the Lauf and Zweibr\u00fccken locations played a key role in that. \u201cThis kind of teamwork enabled us to take full advantage of and combine all the know-how and expertise from both our locations,\u201d explains Project Manager Peter Kleinhans. And the fact that the results are extraordinary can be seen, for example, in the corresponding lifting capacities, which are 10 to 15 percent higher in many areas and with certain configurations can even go all the way up to 30 percent 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-meter boom length at a radius of 12 to 24 meters. There is also its lifting capacity of 11 tonnes at a radius of 42 meters with a boom length of 47 meters, which is also at the very top \u2013 to name just two examples. This impressive run is continued by the new crane\u2019s system length: The 70-meter main boom can be extended by a generous 42 meters with a HAV main boom extension, making it possible to reach a system length of 112 meters. Also notable: All available main boom extensions from 5.8 to 36 meters are self-rigging.<\/p>\n\n\n\n

A sophisticated counterweight concept<\/strong><\/strong><\/p>\n\n\n\n

The crane can pick up its total counterweight of 80 tonnes in three lifts: 49.6 tonnes with a full 360\u00b0 radius of up to 6.2 meters 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 meters across the full radius. \u201cThanks to the IC-1 Plus crane control system, which comes as standard, the available radius can even be significantly increased at certain slewing angles,\u201d Peter Kleinhans underscores. 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 flexibility for transportation logistics. This means that relatively small trucks can be used for transportation when required by space conditions at a work site.<\/p>\n\n\n\n

Taxi crane with 12-tonne axle load<\/strong><\/strong><\/p>\n\n\n\n

The Tadano team is also tremendously proud of the outstanding transportation configuration 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-meter heavy-lift runner on board while remaining within a 12-tonne axle load configuration \u2013 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 the whole thing with 16-inch steel rims. The result? 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 five-axle unit\u2019s enormous versatility.<\/p>\n\n\n\n
