Excavator-planner UDS-214 is self-propelled, multi-purpose hydraulic excavator on automotive chassis TATRA-815-2. Machine is assigned for finishing earth works in connection construction with surroundings, and with usage of suitable tool also for excavation and other earth works (digging of foundation excavations, channels, building up and engineering networks maintenance). The main bucket with capacity 0.63 m3 can ripper and lift soils of 2, 3 and 4 classes, but with additional replaceable equipment works with soils of 5-th class with density up to 1800 kg./m3. The excavator has the possibility of horizontal walls handling, maximum arm slope angle is 90 degrees. The excavator is equipped with a comfortable cabin with dependent water heating and two-speed fan, besides there is is a hatch in the ceiling of the cabin for ventilation of the cabin in the warm season.
