Liebherr updates its R922 crawler excavator with more power
Liebherr is launching a revised R922 crawler excavator, replacing the previous R906 and joining the R918 and R926 in the company’s medium weight line-up. 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.

Liebherr launching a revised R922 crawler excavator
718 Liebherr is launching a revised R922 crawler excavator, replacing the previous R906 and joining the R918 and R926 in the company’s medium weight line-up. 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.
Perkins will showcase a complete line-up of Stage IV/Tier 4 Final engine solutions at Bauma, ahead of the new legislation next year. The four cylinder 854F-E34TA will demonstrate much of the technology on offer, as it uses Selective Catalytic Reduction (SCR) with an exhaust additive, plus a Diesel Oxidation Catalyst (DOC). Both Perkins’ 3.4 and 4.4-litre engine lines make do without a Diesel Particulate Filter (DPF), though the larger 7 litre will use a DPF as well.

Dana Holding Corporation used bauma 2013 to reveal its Spicer TE30 powershift transmission for heavy-duty materials handling applications. With five forward and three reverse speeds, the TE30 slots into the range between the TE27 and TE32 transmissions, and is compatible with engines ranging from 225-300kW. The Spicer TE30 transmission benefits from several engineering refinements to improve efficiency. These include decreased spinning speeds of internal components to lower oil churning losses, optimised cl
