According to Wacker Neuson, the company’s latest-generation excavators are “ground-up redesigns offering cutting-edge performance in a very compact package.” The new ET65 and ET90 compact track excavators, says the company, are significantly stronger and heavier, compared with previous models, while fitting in a smaller envelope and delivering increased performance and up to 20 percent better fuel economy.
The ET65 is a 6.5-ton model with a maximum digging depth of 13 feet 9-inches (with its long dipper stick) and has a breakout force of 11,398 pounds and is powered by a 48-horsepower Tier 4-Final Perkins engine.
The ET90, with an operating weight of 9 tons and using a 73.8-horsepower Tier 4-Final Deutz engine, has a breakout force of 15,829 pounds and a maximum digging depth of 15 feet 2 inches with its long dipper stick.
A new three-point, kinematic bucket linkage, along with an expanded, 200-degree angle of rotation, contributes to the machines’ high breakout force, says Wacker Neuson, and helps retain the load in the bucket before dumping.
With a lower center of gravity and significantly reduced dimensions, says Wacker Neuson, the ET65 and ET90 can reach areas not easily accessed by excavators with comparable capabilities. A low-profile engine compartment and larger windows are designed to provide enhanced visibility to both sides of the machine, and the boom has been shifted to the right, enabling the operator to see the entire boom and attachment, as well as the working area.
A new cab for ET65 and ET90 features standard air conditioning, cell phone charger/ holder and air-cushioned operator’s seat. Standard also is a hydraulic “quick-attach,” and a standard diverter valve on the auxiliary-hydraulic line allows switching between a hydraulic thumb and a hydraulic breaker without disconnecting hoses.
