The new RTH 8.51 replaces the previous world record holder, the RTH 6.51, setting new standards for lifting capacity and versatile application.

The innovative new RTH 8.51 is based on a winning engineering concept: by carefully optimising its materials and structural parts, our engineers were able to maintain the same dimensions and weight as the RTH 6.51, but increase its maximum lifting capacity by more than 2,000 kg.

Reach modes: M1, M2, M3

The new RTH 8.51 integrates the 3 reach modes featured on the other models in the range into a single unit, a first in the category:

• M1 – Max Outreach Mode

The RTH boom “Max Outreach Mode”, standard on all Magni rotating telescopic handlers, features a unique extension sequence, with the smaller, end sections extended first and the larger sections kept until last.

This extension mode increases both the range and the load capacity of the boom’s horizontal reach. It also provides greater load capacity at maximum height.

• M2 – Max Capacity Mode

The boom extension “Max Capacity Mode” is a leading-edge characteristic provided on RTH 8.35, 8.39 and 8.46 models. It extends the boom sections in a specific order, starting with the largest and finishing with the smallest sections.

This configuration optimises load capacity in the early stages of extension, thus enabling the boom to handle bigger loads than Max Outreach Mode. This mode is therefore ideal for operations which require lifting of heavy loads within a short operating range.

• M3 – Full Power Mode

The new “Full Power Mode” revolutionises the operation of Magni telescopic handlers, deactivating boom extension and retraction when the working position is reached in order to increase load capacity and improve operating stability. Available on 6- and 8-tonne RTH models, this feature, when combined with Magni winches or winch booms, provides load capacity performance comparable with that of off-road cranes for a given reach.

This mode allows boom extension to be blocked to reduce the impact of the dynamic forces generated by friction on the chains. In practice, extension is deactivated while rotation and lifting are still enabled, in exactly the same way as on telescopic boom cranes.

The main benefit of this function is the significant increase in load capacity, achieved by eliminating the dynamic effects generated by the boom extension system. What’s more, once these forces have been eliminated the horizontal boom can be extended further, increasing reach capacity.

Performance that challenges off-road cranes

With a maximum working height of 51 metres, the Magni RTH 8.51 is the world’s tallest rotating telescopic handler, offering performance that rivals that of compact off-road cranes, while retaining the unique versatility of interchangeable attachments.

The RTH 8.51 is compatible with more than 60 attachments, enabling it to satisfy the requirements of any sector, including:

• cladding panel installation using vacuum handler attachments
• green area maintenance with tree cutter attachments
• special operations made possible by a wide range of specific solutions for any need
