Powered roof supports DTR

0,8...1,0

Advance step, m

1,1 – 4,1

Seam thickness, m

5030 – 6600

Shield resistance, kN

Description

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.
