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

Hyundai Heavy Industries is showcasing a hydraulic hybrid machine at bauma. The R220-LC Hi-POSS is a 22tonne-crawler excavator with a system that allows brake energy to be used for other functions. Hi-POSS stands for Hyundai intelligent power optimal sharing and energy saving. “This is the most novel thing we have,” said Hyundai product engineer Joachim Van de Perre. “With a conventional excavator, when you brake, the energy heats the hydraulic oil. Here we use the energy to perform another task with the ma

With an operating weight of 83.8 – 86tonnes, Hitachi’s giant ZX870LCH-5 excavator is said to be built to operate on the most demanding job sites, such as large-scale construction projects and in busy quarries. The model incorporates the HIOS IIIB hydraulic system, said to allow for faster operation with lower fuel consumption and increased front speed. The ZX870LCH-5 is claimed to have 6% more productivity in H/P mode compared to the previous Zaxis model. Swing torque is also said to have increased by 9% an
Hitachi Construction Machinery (Europe) president and chief executive Moriaki Kadoya believes HCME can achieve 20-30% sales revenue growth in the next five years through its wide range of mining-suited machines. The Hitachi Group subsidiary has a vast range of larger machines, including six crawler excavators – the 1200, 1900, 2600, 3600, 5600, and 800tonne 8000 model – which, Kadoya said, leaves HCME in an ideal position to pursue its ambitious growth target. The construction equipment industry giant also
