Company says machines are ideal for contractors in urban applications.
Terex Construction Americas
, Southaven, Mississippi, offers two wheeled excavators, TW85 and TW110, for North American contractors where the versatility of a wheeled machine is required. The company says that the TW85 and TW110 are ideal for urban applications where contractors want dedicated excavators for lifting, digging and laying pipes.
The Tier 4-compliant, 91-horsepower TW85 wheeled excavator has an operating weight of 18,519 pounds; a maximum digging depth of 13 feet, 5 inches; a maximum reach of 24 feet, 10 inches; and bucket capacities from 3.1 to 12.3 cubic feet. The model is equipped with a cooling system, featuring a reversible fan to promote lower operating noise levels and reduce fuel consumption.
The 102-horsepower TW110 wheeled excavator has an operating weight of 24,229 pounds; a maximum digging depth of 14 feet, 2 inches; a maximum reach of 27 feet, 3 inches; and bucket capacities of 5.26 to 16.85 cubic feet.
Both excavator models are designed around the operator, the company says. With the Terex Fingertip Control, the electric proportional control functions via a roller on the joystick. The short routes on the joystick result in higher precision and operator comfort when working. Terex says the dual-circuit hydraulics system with load-independent flow distribution allows all functions to be controlled simultaneously and independently of each other. And, load sensing technology reduces fuel consumption.
The system has been sensitively tuned to control all functions at all engine speeds, independently of the load. Travelling up to 12 mph, operators can select between two-wheel or all-wheel steering, matching the machine to specific site conditions.
Additionally, the wheeled excavators are equipped with the Terex Smart Control operating system. When designing the new system, Terex says it considered operator comfort, resulting in the introduction of a central control unit that makes it easier to adjust the machine to suit particular applications and operators. A new menu guide makes it simple to navigate around the options and information available, while the 3.5-inch display screen results in easier-to-read machine and engine data at a glance.
Both excavators are equipped with a hydrostatic travel drive that deliver powerful performance with fuel economy. Operating in a closed circuit, the drive system works independently of the working hydraulics system, which allow the operator to simultaneously maneuver, swing and drive. Additionally, the travel drive functions as a braking system. The machines’ automatic idling system improves fuel economy by reducing engine speed upon inactivity, reducing emissions and operating cost. The side-mounted engine on the two excavators acts as a counterweight, helping to ensure the machines’ stability when the excavator arm is fully extended.
Boom options are available for the TW85 and TW110 excavators and include standard and circular setups. The standard articulated arm is designed for high performance excavating, transportation and placement of heavy loads in large working areas, the company says. The circular boom is ideal for inner city construction sites where space is constrained. A monobloc option is available for the TW85 model, offering a staggered boom setup to give the excavator extra dumping height, range and digging depth.
Both excavators can work along walls and other existing infrastructures. The articulated joint on the excavator’s booms allows each machine to be moved to either side at full digging depth. With an articulation angle up to 120 degrees, work can be carried out on the narrowest construction sites.
Supported by the oscillating axle with an inclination angle of 14 degrees, Terex wheeled excavators remain stable on uneven ground. The optional floating function for the dozer blade makes it easier to level the ground and facilitates filling procedures and cleaning at the construction site. The undercarriage can be configured to the jobsite requirements. Undercarriage options include support legs, a support blade and a front dozer blade
A wide range of attachments are available for both the TW85 and TW110 wheeled excavator models, including standard, light-material, ditch-cleaning and swing buckets, as well as a hydraulic transverse cutting unit, ripper tool, hammer adapter, load hook and pallet forks. Quick attach systems are available in either mechanical or hydraulic.
