Rotating telescopic handlers combine precision and safety

Rotating telescopic handlers combine precision and safety

The newly released Manitou MRT 3050 and MRT 2470 complement a particularly wide range that is suited for high-rise construction work. The group becomes the first market operator to offer a rotating telescopic machine with a load bearing capacity of 7 tonnes for a height exceeding 20 metres.

The versatile MRT 3050 combines precision and safety, thanks to easier maintenance access for the operator and stabilizers with a deployment length of up to 6.25 metres. These are now fitted with a strain gauge system, which ensures more accurate and secure detection of the pressure of the stabilisers on the ground. The user can also check the extent of deployment thanks to a dashboard display. Equipped with a two-ratio hydrostatic transmission, the MRT 3050 has a maximum speed of 40 km/h. It is equipped with a Mercedes 176 hp Tier IV Final engine.

With a boom reach of 24 metres for a load-bearing capacity of 7 tonnes, the MRT 2470 is a response to the needs of heavy high-rise construction. Like the MRT 3050, the new MRT 2470 benefits from a new chassis. With a newly designed counterweight, this rotating telehandler maintains perfect stability, even with a maximum load at 24 metres. With its hydrostatic "shift-on-fly" transmission option, this model allows the operator to choose between a manual or automatic gearbox. With two ratios, the maximum speed of the MRT 2470 is 40 km/h. Cab access is facilitated with a wider footboard aligned with the cabin. Optionally, the operator has the benefit of an electronic stairway with an extra step that slides out when the stabilizers are deployed, making it easier to get in and out of the cab. The machine can thus be raised 23 cm when the stabilizers are completely deployed.

For indoor applications, a dual-energy engine with an electrical system is also available as an option, allowing noise pollution and polluting gas emissions to be reduced, and reducing the total cost of ownership (TCO).

Maintenance access is facilitated on the two models to reduce the TCO. The user can easily change the air and oil filters. The grease points have also been positioned so that they can be easily identified by the operator. A screen on the dashboard allows for better preventive maintenance, with information about part replacement intervals, depending on usage. Many services are available on these two models, with the connected solution Easy MANAGER, and an extended warranty available on the whole MRT range, with options of 2, 3, and 5 extra years.

The group has developed a new continuous rotation fork carriage CAT 1200/4000 R. With its 360° rotation, this attachment increases productivity by reducing movements when handling, facilitating the placement of long loads. This model has a width of 1.2m for a front loading capacity of 4 tonnes (+/- 15°). Its capacity is 2500 kg for the rest of the rotation (when the angle of rotation is greater than 15°). This model is intended for handling palletised loads in industrial environments and on construction sites. In collaboration with its engineering office, Manitou's attachments team has designed a connected tool using attachment recognition, a CAN-bus rotation sensor and built-in software. The position and weight of the load, as well as the fork rotation angle and position are checked several times per second, constantly ensuring the safety and stability of the load for the operator. This system also prevents overloading (according to the angle of rotation) and any lowering of the forks when the angle of rotation of the forks is greater than 90°.

The group has also developed a new aluminum extensible rotating aerial work platform basket, "PSE 4200 / 365 ALU", intended for MRT telehandlers. The choice of aluminum for the whole body of the basket (the rotator is still made of steel) allows for a significant weight saving of 150 kg, while maintaining a loading capacity of 365 kg including three people. The offset is significantly increased, allowing users to optimise their working efficiency and to maximise use of their machine's capabilities.
