Powered by a Stage IIIB Liebherr diesel engine, developing 105kW (143hp), the R922 weighs in at 22 tonnes and designed as a general purpose civils machine. Using a Dual Circuit Positive Control hydraulic system, the excavator is said to consume less energy than previous models, resulting in fuel savings for the customer. The machine on show will be exhibited with a 2.7m dipper arm and LC undercarriage. However even with 600mm track pads the R922 does not exceed the 3.0m overall width for road transport in Europe.
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

The new 673 telescopic crawler crane from Sennebogen is said to be powerful, efficient and stable in operation. The machine offers a lifting capacity of 70tonnes crane while its telescoping boom is said to maximise versatility for an array of lifting applications. The new 673 R-HD is said to be rugged and durable and is the first telescopic crawler crane in the firm’s new E-series. Key features include stability and ease of transport, as well as fast set-up times. For on-road transport the crane is less tha
