The inception of the 8.39 ensued from the redesign of the 6.39 model, showcasing upgraded load charts and a noteworthy boost in lifting capacity, elevated by 2 tonnes (4,409 pounds).

For the first time, this machine is equipped with two extension modes, M1 and M2. These two modes give access to two different load charts, to maximise performance in all operating conditions. The standard extension mode, M1, offers the operator the maximum reach and higher load capacities at the maximum height, while M2 mode restricts reach to provide increased load capacity of up to 8 tonnes (17,600 pounds).

Surprisingly reliable and rugged, it is the ideal partner on even the toughest construction sites, while their agility and ease of use guarantee operators a unique experience. No challenge is too complex: safety and precision are assured at even the greatest heights.



The 8.39 is extremely sophisticated, since it can be used, by just changing the attachment, as telescopic handler with the forks, as off-road crane by fitting the winch, and as aerial platform thanks to the basket. What’s more, via the RFID system the machine recognises the attachment and automatically sets the relevant safety devices and load chart.

 Safety and visibility

With ROPS/FOPS Level 2 certification, the cab guarantees best-in-class safety throughout all working phases.

Visibility is also improved, while maintaining regulatory and safety compliance, by moving the cab further forward, increasing the glazing in the top section and installing a more slender steering column.

The new Magni patented “easy access” system makes getting into and out of the cab easier by permitting a slight misalignment between the turret and chassis, facilitating access to the machine.

Operator comfort

As for all other RTH and TH models, the cab interiors have been completely restyled and all panelling is now injection-moulded for improved durability and a better finish. Courtesy lights fitted in various points inside the cab switch on when the door is opened. These LED lights can be dimmed and gradually fade out once the machine is switched off.

The air flows inside the cab have been improved by redesigning the bottom section of the windscreen, to optimise defrosting in even the coldest weather.

A sunblind which can be locked in two different positions is fitted in the roof, above the operator’s head, to guarantee the highest degree of comfort on even the sunniest days.

In the new cab both the armrests, which move with the seat, can be raised, creating a convenient storage compartment underneath the right armrest. An air-suspended, tilting premium seat with headrest is also available.

New MCTS (Magni Combi Touch Screen) on-board control system

The software installed on the new RTH range, also accessible from the touch screen, has been completely renewed. The restyled interface graphics ensure easy, intuitive use with user-friendly icons to identify the various functions.

In an upgrade from the previous release, the software now includes a main menu accessible from the various thematic screens, with new functions to provide a smoother, pleasanter user experience.

The main functions and innovations include:

  • Handling mode: allowing boom and traction speeds to be separated for more precise, faster movements when extending the boom while moving the vehicle.
  • Eco mode: this allows the engine rpm to be automatically reduced once the maximum speed is reached during on-road travel at constant speed, reducing fuel consumption and thus CO2 emissions.
  • Dedicated pre-settings: three new presets which can be selected by the operator, from the most precise to the most reactive, to optimise the performance of the attachment used.

Another important innovation is the Magni LLD (Live Load Diagram) system, which offers three different versions of the load chart screen for a complete view of the operating limits, to enable work in total safety:

  • Standard, displaying all the load bands (also featured on previous versions).
  • Dynamic, displaying the working area available in relation to the load being lifted.
  • 360°dynamic, which displays the working area available from above, enabling greater precision when working in conditions of varying stability.

Last but not least, like the whole of the new RTH range, this model is equipped as standard with a reversing camera, visible in the MCTS monitor, activated automatically when reverse gear is engaged.
