New Generation of Terex Excavators



Terex recently unveiled three new compact excavators to the market – the TW85 and TW110 wheeled excavators and the TC125 midi crawler excavator.

Designed and manufactured at Terex Construction’s Crailsheim facility, the new 2014 machines are equipped with the latest diesel engines which meet the EU Stage IIIB emission standard requirements (corresponds to US EPA Tier 4 interim standard), and are also equipped with proprietary Terex Smart Control system.

The two wheeled excavator models are larger than the existing TW70, while the new tracked midi-excavator is the largest in the range of 14 models extending from 1,158 kg to 12,500 kg.

TW85-engineEngines with more power and lower emissions

In comparison to previous models, the new engines demonstrate an increase in power of 10 to 14% (depending on the model) with reduced fuel consumption and significantly lower emission levels. 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 74.4 KW (101 HP) in the TW85 model and an output of up to 85 KW (116 HP) in the TW110 and TC125 models. Both Deutz engines feature an electronically-controlled high pressure common rail injection system and generate a maximum torque of 410 Nm (at 1600 rpm).

The TC125 is a short-tail machine with extra-wide, 2,500 mm x 510 mm dozer blade for more efficient dozing and increase stability. Load sensing hydraulic ensure only the required power is used where it is most in demand. The boom allows for lateral parallel adjustment for working in restricted areas. The angle of articulation is 65° to the left and 56° to the right.

The spacious, sound-insulated ROPS cab features sliding window in the cab door, a panoramic rear window and a skylight. The front window is supported in pneumatic springs and can be slid under the cab roof.

The TW85 can TW110 can travel at up to 36 km/h while the short tail make for easier working in restricted areas. Each is available with three undercarriage options - outrigger, support blade or front dozer blade. For difficult underfoot condition, the drive can change from 2-wheel drive to 4-wheel drive

The oscillating axle with up to 14° angle helps maintain ground contact when travelling over uneven ground.

Boom options include standard articulated boom and boom dipperstick. On the TW85, there is also circular boom, and monobloc offset boom option.

Terex-controlTerex Smart Control system developed in-house

A fundamental innovation in the design of the excavators is Terex Smart Control (TSC) - a completely new control and operating system.

This includes new control electronics through to a new instrument and joystick design. Maik Schulze, Construction and Development manager, explains:

“The Terex Smart Control system was developed in-house. Our objective 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.”

Redesign of the control elements

The main control elements, such as the joystick and the buttons, have undergone a complete redesign to offer improved ergonomics, surface feel, and grip. Other control functions are integrated into the joystick, which are directly selectable.

These innovations are designed to provide a noticeable improvement in terms of handling and operator comfort, enabling quicker, smoother and more precise work movements as well as increased performance.

The new keypad incorporates fundamental excavator functions and the extra-large keys provide easy operation, even while wearing work gloves.

Four independent additional control circuits

Up to four independent additional hydraulic control circuits provide efficient work and powerful operation of attachments in all three excavator models and can be operated simultaneously.
