The TW85 and TW110 wheeled excavators have operating weights of 18,519 and 24,229 pounds, respectively. Terex Fingertip Control has a roller on the joystick. The dual-circuit hydraulics system with load-independent flow distribution allows all functions to be controlled simultaneously and independently of each other. Load-sensing technology reduces fuel consumption. Hydrostatic travel drive operates in a closed circuit, independent of the working hydraulics system. The side-mounted engine acts as a counterweight. Knickmatik cylinders permit work alongside walls and other obstacles. The articulated joint on the boom allows the machine to be moved to either side at full digging depth. It has an articulation angle up to 120 degrees.
