Bonfiglioli is launching heavy duty drives for large machines
Bonfiglioli Trasmital has developed a new series of travel drive gearboxes for use in large, heavy duty tracked machines. The firm is now offering three new product sizes, the 722C, 724C and 726C, which extend its range of tracked travel drives. The 722C develops a maximum torque of up to 330,000Nm, making it suitable for use on excavators of 120-150tonnes, as well as cranes and drilling rigs of 180-230tonnes. The 724C develops a maximum torque of up to 450,000Nm, and is specially designed for large cranes

The BSC 1409 D from Putzmeister is a self-propelled concrete pump designed specifically for concreting drilled piles on unfinished surfaces. In contrast to using truck-mounted concrete pumps for concreting drilled piles, it does not need supports to be set up each time it changes location. Compared to concreting with a delivery pipe, placement speed with the tracked concrete pump is now said to be considerably higher.
Liebherr’s new 173tonne LB 44-510 rotary drilling rig offers 510kNm of torque, while the model’s in-house manufactured hydraulic drive provides automated torque adjustment, optimal continuous speed and four electronically adjustable speed ranges.
The LB 44-510 has been designed for drilling diameters of up to 3m and up to 92m drilling depths. The drilling rig is driven by a 505kW Stage IIIB/ Tier 4i V8 diesel engine.

Ammann is using INTERMAT to reveal its UniBatch range of asphalt mixing plants. With capacities from 80-350 tonnes/hour, this new plant type incorporates flexibility, and a larger selection of modules to allow the system to be expanded as required. Energy efficiency and reduced emissions are key elements of the UniBatch range, which is said to be is compatible with all of Ammann's recycling technologies. Mixer capacities extend from 1.3-4.3tonnes, hot silo storage is from 45-120tonnes and mixed material sto
