Powered roof supports DTR

Advance step, m
1,1 – 4,1
Seam thickness, m
5030 – 6600
Shield resistance, kN

Designed for supporting and controlling the roof in mined area of face while operating flat seams of 1.1-4.7 m thickness.

Provides efficient operation with heavy and medium-weight roofs thanks to shield high load capacity from 850 to 1050 kN/m2.

Main advantages:

  • design is optimized for operation in seams with hard-collapsed roof;
  • special construction of basement lifting mechanism and shield kinematic parameters to operate in soft soil conditions;
  • long-lifetime European-made power hydraulic system produced in accordance with Eurostandart EN 1804-2;
  • effective and reliable European-made control system of different types: pilot control, multi-hose control, electric-hydraulic control.
