The TW85 and TW110 wheeled excavators and the TC125 midi crawler excavator are designed and manufactured at Terex Construction’s Crailsheim facility.
Using latest clean engine technology has reduced emissions and fuel consumption while also increasing power by up to 14%, depending on model. All three excavators have newly developed water-cooled, 4-cylinder turbo diesel engines with charge air cooling and cooled exhaust gas recirculation, offering more power from reduced displacement.
With a nominal engine speed of 2000 rpm, the updated excavators produce a power output of up to 74.4kW in the TW85 model and up to 85kW in the TW110 and TC125 models. Both engines feature an electronically-controlled high pressure common rail injection system and generate a maximum torque of 410 Nm (at 1600 rpm).
A diesel particle filter reduces emissions by 90% compared to previous models.
Peter Hirschel, managing director of Terex Compact Germany, said: "By concentrating on our core competency of compact construction machinery, we achieved a sustainable improvement in our products. The new Terex compact excavators are not only cleaner, but we have embarked upon considerable development to be able to offer the customer real advantages in productivity. Measurably more power, noticeably more comfort for the operator, and therefore increased work efficiency and productivity."
The Terex Smart Control (TSC) operating system includes new control electronics through to a new instrument and joystick design. "The Terex Smart Control system was developed in-house,” said construction and development Maik Schulze. “Our requirement was to optimize operation and comfort, power, and ergonomics from the perspective of the operator. The operator shouldn't have to adapt to the excavator, the excavator should meet the needs of the operator."
