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

A new range of reflectorless total stations has been developed by Topcon. Called the ES series, the new models also feature TSshield – a Topcon Group innovation using a multi-function telematics-based communication module that locates the instrument.
EmiControls new large turbine – the V22 – will be showcased at bauma 2013. The company, which began trading independently in 2012, offers mobile and stationary solutions for optimum dust emission control during demolition, recycling plant, quarry, mining and industrial-based applications.
Doosan Construction Equipment has launched a Dash-3 version of its popular reduced-radius 15tonne excavator, the DX140LCR-3. Powered by a Cummins QSB4.5 Stage IIIB-compliant engine, with exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), the machine has 10% more power and 15% more torque than the previous model. Both main boom and dipper arm forces get an 8% boost, while travel speeds are increased to 5.3km/h, resulting in a claimed a 10% increase in productivity.
