Tadano introduces new 80-tonne all-terrain crane

Demag has launched the AC 80-4, a crane 80-tonne crane that encompasses a important increase that’s 60 meters (196.9 ft) lengthy and that, with some configurations, makes it attainable to have the longest important increase attain within the class of as much as 120 tonnes (132 US ton). The AC 804 can raise 5.4 tonnes (6 US ton) at a radius of 14 meters (45.9 ft). It additionally raises the bar with its important increase prolonged to 50 m (164.0 ft). 

If the principle increase size of 60 meters (196.9 ft) just isn’t sufficient, the attain will be expanded with a 6.5 metre (21.3 ft) important increase extension that may be offset by 25° and 50°. Its capability is 23.8 tonnes (26.2 US ton), that means that it may be used to raise heavy masses over obstacles. Because the extension will be folded and carried on the principle increase, it may be prepared to be used significantly rapidly. 

As well as, there’s a 1.50-meter (4.9 ft) runner with a capability of 26.6 tonnes (29.3 US ton) out there for the Demag AC 80-4. Accordingly, the AC 80-4 can be really helpful for indoor initiatives. The primary increase will be lowered as much as 3° under its horizontal place in order that potential work at top will be simply eradicated and the jibs will be put in rapidly and safely.

All Demag all terrain cranes are characterised by a compact design, and the brand new AC 80-4 is not any exception: Practically all of its dimensions are shorter than these of different four-axle items in its class. Its complete size is 12.15 meters (39.9 ft), the provider size is 10.60 meters (34.8 ft), its top doesn’t exceed 3.85 meters (12.6 ft), and the entrance overhang is a modest 1.49 meters (4.9 ft). 

In a position to journey on the street

Nevertheless, the AC 80-4 doesn’t want to attend to get to a piece website to indicate off its qualities. As an alternative, it does so when already underway. Amongst different issues, this is because of its subtle counterweight design, which makes it attainable to have a most counterweight of 17.7 tonnes (19.5 US ton). 

On the street, it might probably transport as much as 9.3 tonnes (10.3 US ton) of this counterweight itself whereas remaining underneath a 12-tonnes (13.2 US ton) axle load restrict, and all whereas additionally carrying the 6.5-meter (21.3 ft) swing-away jib. Actually, this configuration even features a three-sheave hook block on board. 

Mercedes-Benz engine and transmission

The AC 80-4 is supplied with a strong Mercedes-Benz engine for environment friendly journey and operation. It outputs a most energy of 340 kW (462 PS) and delivers a most torque of two,200 Nm. 

The state-of-the-art diesel engine conforms to EU Stage V and Tier 4 Ultimate emission necessities and will be downgraded to fulfill ECE-R96 regulation. A Mercedes-Benz G230-12 transmission, along with a drivetrain from the identical producer, is answerable for transmitting the engine’s energy to the street. 

With twelve ahead speeds and two reverse speeds, all-wheel steering as commonplace, and two or three pushed axles, this makes the AC 80-4 nicely suited not solely to the challenges of tough terrain at work websites, but additionally to quick journey on highways and long-distance drives.

All of the highlights from the Demag World of Improvements

As soon as on the work website, the brand new Demag Encompass View makes it simpler for crane operators to place the AC 80-4. This patented system makes use of the 4 crane cameras to indicate a computer-assisted diagram of the attainable outreach of the outriggers, in addition to the counterweight tailswing radius on the crane’s present location. 

Demag Encompass View additionally helps the driving force on the way in which to the development website. The cameras can ship pictures of the crane facet areas when turning, facilitating the crane driver to detect cyclists, pedestrians, or any obstacles. This operate is activated robotically when the indicator is operated.

The AC 80-4 additionally comes with the progressive Demag IC-1 Plus management system, which is taken into account by many specialists to be the main crane management system in the marketplace. Throughout operation, IC1 Plus calculates the crane’s lifting capability for each increase place as a operate of the superstructure’s slewing angle. Which means the utmost out there lifting capability can be utilized with any outrigger configuration, together with asymmetrical ones. 

This benefit is maximized when mixed with the Flex Base system, which makes it attainable to increase the outriggers to any level inside their vary, as this technique permits the crane to increase its outriggers all the way in which to surrounding obstacles even when an asymmetrical configuration is required. That makes it attainable to make use of the utmost attainable lifting capability in any scenario and is ideal for tight work websites particularly. It additionally permits the AC 80-4 to care for lifts that might usually be the unique purview of bigger cranes – and in locations that these cranes wouldn’t have the ability to attain in any respect resulting from their dimensions. 

The expanded graphic show gives the utmost attainable comfort: it’s designed within the type of a capability radar and gives crane operators with further info on lifting capability throughout the working vary whereas accounting for the increase place and the slewing radius, Furthermore, the automated counterweight detection operate helps crane operators deciding on the counterweight that has been arrange, as IC1 Plus will robotically detect it. 

Along with the IC-1 Plus management system, the crane is out there with the IC-1 Distant telematics resolution, which makes it attainable to remotely learn and diagnose all essential crane knowledge and permits house owners to combine the AC 80-4 into their fleet administration system.

Emissions and noise are a always rising drawback that in lots of instances is now not being tolerated, particularly in bigger cities. The commercial sector is predicted to offer sustainable options that may assist cut back this drawback. For this reason the ESTA-award-winning E-Pack is out there for the AC 80-4. This function is an electro-hydraulic system designed to be related to the crane. It comes with an built-in 32-kW electrical motor that makes extraordinarily quiet zero-emission crane operation attainable. Particular purposes for the E-Pack embrace crane jobs inside buildings, in dense city areas, and at evening in residential areas – in different phrases, underneath situations during which the corporate working the crane might must face stricter necessities that make typical crane operation with a diesel engine unimaginable.
