T1155III Surface Miner Features & Benefits

Advanced technology for improved machine efficiency

SmartTEC performance monitoring assists operators with adjustments to machine controls to help improve efficiency and tracks the operational performance of the machine on a consistent platform across all machine models.

Elevated operator visibility and comfort

The elevating rollover protective module cab features LEXAN glass, filtered and pressurized air, heating and air-conditioning. The cab’s vantage point allows an optimal view of the boom, trench and conveyor.

Superior ground penetration and low chain wear

A rotary power trencher drive motor and splined headshaft produce a low speed and high torque which provide maximum ground penetration and low chain wear for optimal production results.
