DORTMUND, Germany - TEREX O&K presented two new hydraulic excavators at the Bauma Fair in Munich.
The new RH 70 is a 122-t heavy backhoe excavator powered by a Caterpillar C18 engine and provides 8.0-m standard bucket capacity in combination with a 7.8-m monoboom and a 3.3-m stick. This is a 33% capacity increase, compared with the smaller RH 40-E, says the manufacturer. The RH 70 features electric-over-hydraulic controls and offers the largest operator cab in its class, including a durable control panel specifically made for mining applications. Other key features are a triple-race swing-roller bearing with internal lube lines and a fully independent oil cooling system. The RH 70 nicely pairs with 50- to 120-t trucks.
The new RH 340-B excavator is the latest addition to the popular RH 340 line. The RH 340-B is powered by two Caterpillar 3512C engines but also provides the option of two Cummins QSK 45s. Both engine sets deliver a massive output of 2,240 kW (3,000 hp). Another innovation is a more powerful hydraulic system with higher-capacity main pumps, delivering an impressive oil flow of 4 x 1,300 L/min. There are four main valve blocks to accommodate this increased oil flow.
